This study characterizes the wave climate in the Arctic spanning 1992-2014 from a merged altimeter data set and a wave hindcast that uses CFSR winds and ice concentrations from satellites as input. The model performs well, verified by the altimeters, and is relatively consistent for climate studies. The wave seasonality and extremes are linked to the ice coverage, wind strength, and wind direction, creating distinct features in the wind seas and swells. The altimeters and model show that the reduction of sea ice coverage causes increasing wave heights instead of the wind. However, trends are convoluted by interannual climate oscillations like the North Atlantic Oscillation (NAO) and Pacific Decadal Oscillation. In the Nordic Greenland Sea the NAO influences the decreasing wind speeds and wave heights. Swells are becoming more prevalent and wind-sea steepness is declining. The satellite data show the sea ice minimum occurs later in fall when the wind speeds increase. This creates more favorable conditions for wave development. Therefore we expect the ice freeze-up in fall to be the most critical season in the Arctic and small changes in ice cover, wind speeds, and wave heights can have large impacts to the evolution of the sea ice throughout the year. It is inconclusive how important wave-ice processes are within the climate system, but selected events suggest the importance of waves within the marginal ice zone.}, journal = {The Cryosphere}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-14109175,~to-add-doi-URL,arctic-region,artic-sea-ice,climate,remote-sensing,waves-energy,wind}, lccn = {INRMM-MiD:c-14109175}, number = {4} }

Our tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work. The combination of our tools and our users is a vast and growing digital commons, a pool of content that can be copied, distributed, edited, remixed, and built upon, all within the boundaries of copyright law. [::License design and rationale] All Creative Commons licenses have many important features in common. Every license helps creators -- we call them licensors if they use our tools -- retain copyright while allowing others to copy, distribute, and make some uses of their work -- at least non-commercially. Every Creative Commons license also ensures licensors get the credit for their work they deserve. Every Creative Commons license works around the world and lasts as long as applicable copyright lasts (because they are built on copyright). These common features serve as the baseline, on top of which licensors can choose to grant additional permissions when deciding how they want their work to be used. [\textbackslash n] A Creative Commons licensor answers a few simple questions on the path to choosing a license -- first, do I want to allow commercial use or not, and then second, do I want to allow derivative works or not? If a licensor decides to allow derivative works, she may also choose to require that anyone who uses the work -- we call them licensees -- to make that new work available under the same license terms. We call this idea '' ShareAlike'' and it is one of the mechanisms that (if chosen) helps the digital commons grow over time. ShareAlike is inspired by the GNU General Public License, used by many free and open source software projects. [\textbackslash n] Our licenses do not affect freedoms that the law grants to users of creative works otherwise protected by copyright, such as exceptions and limitations to copyright law like fair dealing. Creative Commons licenses require licensees to get permission to do any of the things with a work that the law reserves exclusively to a licensor and that the license does not expressly allow. Licensees must credit the licensor, keep copyright notices intact on all copies of the work, and link to the license from copies of the work. Licensees cannot use technological measures to restrict access to the work by others. [::Three '' Layers'' Of Licenses] Our public copyright licenses incorporate a unique and innovative '' three-layer'' design. Each license begins as a traditional legal tool, in the kind of language and text formats that most lawyers know and love. We call this the Legal Code layer of each license. [\textbackslash n] But since most creators, educators, and scientists are not in fact lawyers, we also make the licenses available in a format that normal people can read -- the Commons Deed (also known as the '' human readable'' version of the license). The Commons Deed is a handy reference for licensors and licensees, summarizing and expressing some of the most important terms and conditions. Think of the Commons Deed as a user-friendly interface to the Legal Code beneath, although the Deed itself is not a license, and its contents are not part of the Legal Code itself. [\textbackslash n] The final layer of the license design recognizes that software, from search engines to office productivity to music editing, plays an enormous role in the creation, copying, discovery, and distribution of works. In order to make it easy for the Web to know when a work is available under a Creative Commons license, we provide a '' machine readable'' version of the license -- a summary of the key freedoms and obligations written into a format that software systems, search engines, and other kinds of technology can understand. We developed a standardized way to describe licenses that software can understand called CC Rights Expression Language (CC REL) to accomplish this. [\textbackslash n] Searching for open content is an important function enabled by our approach. You can use Google to search for Creative Commons content, look for pictures at Flickr, albums at Jamendo, and general media at spinxpress. The Wikimedia Commons, the multimedia repository of Wikipedia, is a core user of our licenses as well.

Two contrasted bench-scale methodologies have been used to ratify the results. Cypress showed low ignitability and consumability and high sustainability and combustibility. The low ignitability of C.~sempervirens suggests a potential resistance to moderate wildfires. Cypress stands could be a promising land management tool to reduce the wildfire initiation risk. Accurate determination of flammability is required in order to improve knowledge about vegetation fire risk. Study of the flammability of different plant species is essential for the Mediterranean area, where most ecosystems are adapted to natural fire but vulnerable to recurrent human-induced fires, which are the main cause of forest degradation. However, the methods used to evaluate vegetation flammability have not yet been standardized. Cupressus sempervirens is a native or naturalized forest tree species in the Mediterranean area that is able to tolerate prolonged drought and high temperatures. The aim of this study was to characterize the flammability of C.~sempervirens var. horizontalis at particle level by using different bench-scale calorimetry techniques (mass loss calorimeter, epiradiator and oxygen bomb) to determine the main flammability descriptors (ignitability, sustainability, combustibility and consumability) in live crown and litter samples. Our findings indicate that this variety of cypress is relatively resistant to ignition because of the high ash content, the high critical heat flux, the high time to ignition displayed by both crown and litter samples and the ability of the leaves to maintain a high water content during the summer. We also discuss the possibility of exploiting some morphological, functional and ecological traits of the species to construct a barrier system (with selected varieties of cypress) as a promising complementary land management tool to reduce the fire spread and intensity in a Mediterranean context. [Excerpt: Discussion and conclusions] [...] The FMC of live C. sempervirens samples was relatively high and stable between April and the middle of August (84-96\%). Furthermore, the low variability in the water content across the crown layers ( Fig. 3) may have important implications for crown fire potential ( Van Wagner, 1977). Madrigal et al. (2013) reported a wider range of FMC for Pinus pinaster needles (95-155\%), whereas Viegas et al. (2001) indicated that the FMC of live Mediterranean forest fuels may be as low as 50-60\,\% during the summer season, much lower than the value detected in the present study in live crown samples of cypress. Ignition and fire occurrence are closely related to the moisture content of live and dead fuel ( Dimitrakopoulos and Papaioannou, 2001) and fresh leaves of Mediterranean species appear to become very flammable when the moisture content decreases below 75\,\% ( Chandler et al., 1983) or below 100\,\% in the case of pine needles ( Van Wagner, 1977). An interaction between the physiological state of a live plant (which determines the moisture content) and the concentration of volatile compounds has also been reported ( Weise et al., 2005 and Alessio et al., 2008). During an intense wildfire, the effect due to accumulation of gasified volatile organic compounds (VOCs) may be stronger than the effect due to a low water content, thus explaining specific occurrences such as extreme rate of fire spread and eruptive fire events ( Viegas and Simeoni, 2011). [\textbackslash n] The live fresh samples of C. sempervirens did not ignite in MLC tests performed at 25 kW/m2, whereas in a previous study, live P. pinaster needles with similar FMC (95\%) ignited at the same heat flux ( Madrigal et al., 2013) ( Supplementary Fig. 1). Notably, the HRR curve obtained for C. sempervirens at 35 kW/m2 was similar to that obtained by Madrigal et al. (2013) for live P. pinaster needles at a lower heat flux (25 kW/m2). In EPI2, at 25 kW/m2 ( Table 5), the IF of fresh cypress live fuel was as low as 23\,\%, while at 55 kW/m2, the IF was 100\,\%, for both crown fresh samples and litter samples (conditioned and oven-dried). These results are consistent with the CHF values determined in MLC tests. [\textbackslash n][...] [\textbackslash n] The TTI and CHF are the most representative descriptors of ignitability. Both TTI (at 50 kW/m2) and CHF of live cypress fuel obtained with MLC in the present study were significantly higher than those determined by Madrigal et al. (2013) for live P. pinaster needles with the same FMC value (95\%). The ignitability of common cypress was much lower than that of P. pinaster. Live C. sempervirens leaves also displayed the longest TTI in a comparative study of ornamental species Ganteaume et al. (2013a). However, based on TTI, common cypress has been reported to be the most flammable of several Mediterranean species tested ( Liodakis et al., 2002). This discrepancy may be due to different ignition devices used in the two studies. [\textbackslash n] Heat content is known to be highly dependent upon the chemical composition of a fuel. The GHC values obtained in this study for live C. sempervirens samples in the oxygen bomb test were higher than those obtained for litter ( Table 3). Whereas, in contrast to the findings of Elvira and Hernando (1989), only slight differences in GHC values of live samples were found between spring and summer in the present study ( Table 4). Madrigal et al. (2011) reported a higher GHC for live P. halepensis and P. pinaster needles than for C. sempervirens and Pinus pinea. Even greater differences were observed between species on comparing the GHC of litter samples ( Supplementary Table 2). Liodakis et al. (2002) reported a lower GHC for C. sempervirens leaves that for other Mediterranean species, both conifers and broadleaf species, possibly due to differences in the proportion of chemical components in the leaves and to differences in the residual mass fraction. [\textbackslash n] [...] [\textbackslash n] In highly resinous species (i.e. pines) and during the heating phase, the effect of volatile flammable gases (VOCs) is crucial in priming and/or accelerating combustion (Chetehouna et al., 2009). Our findings indicate the natural resistance of live fuel of common cypress to the initial stages of combustion (ignitability). The gases produced by thermal degradation of cypress live fuel did not ignite, irrespective of the heat source (EPI or MLC) or the heat flux to which the samples were subjected. The VOCs stored in cypress leaf glands (Della Rocca, 2012 and Moya and Moya, 2013d) are probably degassed (Greenberg et al., 2006 and Ciccioli et al., 2014) when vegetation is warming up (at 60-150 \textdegree C), and thus will not contribute to ignition. Moreover, cypress is not a resinous species in the strict sense. Neither the xylem or the bark produce resin constitutively, but only as consequence of mechanical wounds or lesions due to pathogens or pests. [\textbackslash n] In Mediterranean regions characterized by long dry summers, litter appears to play a crucial role in fire risk and transmission (Hogkinson, 2002). Both conditioned and oven-dried C. sempervirens litter samples always ignited (IF 100\%); however, in the present study all flammability parameters (except TTI) measured at 35 kW/m2 were lower than those obtained at 25 kW/m2 for P. pinaster litter with the same FMC (11\%) by Madrigal et al. (2011) ( Supplementary Table 2). Comparing different Mediterranean species, Petriccione (2006) classified the flammability of cypress litter as moderate-high, similar to that of Myrtus communis, Q. ilex, O. europea and P. halepensis, but lower than that of Quercus pubescens, Fraxinus ornus, P. pinaster and Genista aetnensis. [\textbackslash n] In nature, C. sempervirens litter has a high bulk density ( Ganteaume et al., 2013b), as the small segments accumulate in thick layers, also due to a low mineralisation rate ( Della Rocca et al., 2006). These traits reduce the circulation of air in the litter, which may act like a sponge and retain humidity, thus hampering ignition. A thick litter layer is also known to favour self-extinction of fire ( Orme\~no et al., 2009). [\textbackslash n] In this study, the RMF at the end of the test was considered as ash content. In the MLC tests, the ash content of cypress fresh fine fuel ranged from 3.5 to 6.8\,\%. This is consistent with the results reported by Dimitrakopoulos and Panov (2001) who obtained higher values of mineral ash for C. sempervirens leaves (4.73\%) than for other Mediterranean species such as Q. ilex (2.9\%) and P. brutia (2.8\%). The heat content of plant material has been demonstrated to be negatively related to ash content. A higher ash content essentially indicates that there is less mass to burn ( Mutch and Philpot, 1970 and Philpot, 1970), thus influencing fire sustainability and consumability. [...] [Management recommendations and future research] Common cypress is known to produce a deep dense litter that is difficult to ignite and even prevents the development of understory vegetation due to a presumed allelopathic effect. This species is also often planted as a windbreak to protect valuable crops from prevailing winds in the Mediterranean area. In addition to these traits, the findings of our laboratory trials, which have demonstrated the low ignitability of crown and litter cypress samples, encourage further studies at tree and plantation levels to assess the effectiveness of cypress barriers as a silviculture measure to reduce wildfire initiation risk in sensitive sites (e.g. WUIs). Well designed plantations constructed with suitable varieties of cypress (selected for habit and resistance to pathogens causing severe dieback and resin exudation, e.g. cypress canker) and taking into account topography, flammability risk mapping, land use etc. may be useful for creating buffer zones to hinder or prevent the rapid spread of wildfire, also decreasing the likelihood that a surface fire will become a crown fire. The ability of cypress plantations to slow fire progression is derived from a combination of properties of individual trees. The need of transposing laboratory results and empirical observations to a real scale, lead the Diputaci\'on de Valencia (Spain) and the province of Siena (Italy) to plan the realization of the first experimental plantations of the 'cypress system' as a way to conduct further research aimed at improving prevention against wildfires. Useful information on setting up operational cypress plantations as firewalls is reported in Della Rocca et al.

Here, we build upon this experience and present the results of a global statistical analysis and a predictive model for low temperature treeline positions. We identified 376 natural treelines from satellite images across the globe, and searched for their closest climatic proxies using a climate database. The analysis included a snow and a water balance submodel to account for season length constraints by snow pack and drought. We arrive at thermal treeline criteria almost identical to those that emerged from the earlier in situ measurements: tree growth requires a minimum length of the growing season of 94 days. The model yields best fit when the season is defined as all days with a daily mean temperature {$>$}0.9 \textdegree C, and a mean of 6.4 \textdegree C across all these days. The resultant treeline model 'TREELIM' offers a robust estimation of potential treeline elevation based on climate data only. Error terms include imprecise treeline position in satellite images and climate approximations in mountainous terrain. The algorithm permits constraining low temperature limits of forest growth worldwide (including polar treelines) and also permits a bioclimatic stratification of mountain biota, for instance, for biodiversity assessments. As a side product, the model yields the global potentially forested area. The results support the isotherm theory for natural treeline formation. This completely independent statistical assessment of the climatic drivers of the global treeline phenomenon confirmed the results of a multi-year measurement campaign. [Excerpt: Basic model assumptions and definition of climatic treeline proxies] From our earlier works with data loggers (K\"orner and Paulsen 2004), it emerged that only three independent parameters are necessary to model treeline elevation by standardized meteorological data: (a) a threshold temperature DTMIN that constrains the growing season; (b) a minimum mean temperature for all days of the growing season SMT as defined in (a); (c) a minimum length of the growing season LGS. The definition of the growing season is a central issue, because temperatures outside the growing season have no predictive value (K\"orner 2012). The model, thus, needs to select periods suitable for tree growth, which means, warm enough conditions with sufficient soil moisture and no snow cover. [\textbackslash n] Defining the beginning and end of the growing season by a critical air temperature only (as in K\"orner and Paulsen 2004) turned out to be problematic at a global scale because this procedure does not account for irregular seasonal temperatures at equatorial latitudes, and it does not account for snow pack and drought. Therefore, the TREELIM model presented here uses a LGS representing the sum of days with a daily mean temperature above a defined threshold temperature (DTMIN). The mean temperature of the growing season (SMT) for any site is then calculated by averaging the daily means for all these days. Days during which snow is present or during which soil water is not available do not count for season length [...] [\textbackslash n] [...] [::Snowpack] The snow module of TREELIM accounts for the assumption that trees do not exert significant growth as long as there is late-laying snow on the ground. Snow pack may thus constrain the length of the growing period, despite warm air temperatures. It was assumed that all precipitation that falls at daily mean temperatures {$\leq$}0 \textdegree C fall as snow, and snow was assumed to stay and accumulate on the ground as long as daily mean temperatures remained {$<$}0 \textdegree C. If a snow layer is present, snow is assumed to melt whenever daily mean temperatures are {$>$}0 \textdegree C at a rate of 0.84 kg m-2 day-1 for each degree {$>$}0 \textdegree C (the WATFLOOD model; http://www.civil.uwaterloo.ca/watflood/). Sublimation was ignored. [\textbackslash n] Whenever rain falls on an existing snow layer, this water cools to 0 \textdegree C and the thermal energy (4.186 kJ kg-1 K-1) is used to melt snow (333.5 kJ kg-1 snow). Thus, 1 mm of rain melts 1/80 kg m-2 snow per degree air temperature above 0 \textdegree C. The quantity of snow pack (in kg m-2) was calculated by a simple input-output model with a daily resolution: snow layer at day (i) = snow layer at day (i - 1) + snowfall at day (i) - snow melt at day (i). [\textbackslash n] [...] [::Site water balance] [...] The water balance equation was solved by a submodel of TREELIM that accounts for precipitation (liquid and solid), evapotranspiration, and the resulting soil water content. Since climate databases offer only monthly precipitation, we had to approximate actual rainfall regimes, assuming that air temperature determines saturated vapour content of the air. We then adopted a temperature-related stepwise interpolation of mean daily rainfall from annual data with a monthly resolution. This given amount of precipitation water was allocated by plausibility to precipitation events in the following way: The mean per day event was assumed to be 5 mm if the monthly mean T was {$<$}5 \textdegree C, 10 mm for 5-10 \textdegree C, 15 mm for 10-15 \textdegree C, 20 mm for {$>$}15 \textdegree C. For instance, if the monthly mean temperature is 7.3 \textdegree C and the monthly precipitation is 27.4 mm, precipitation events are assumed to be 10 mm each, one on day 7, one on day 14, and the remaining 7.4 mm are assumed to fall on day 21. [\textbackslash n] This procedure is more realistic than for instance splitting monthly precipitation into 30 events. Since soil moisture is buffering moisture availability, the actual fragmentation of monthly precipitation is not very critical, except for conditions where drought is critical, which is rare at alpine treeline elevations. Errors introduced by this procedure are certainly small compared to the uncertainty of actual precipitation at treeline, based on climatic layers derived from low elevation climate stations. [::Daily Potential evapotranspiration] (DPET) was estimated using the Hargreaves equation (Hargreaves and Samani 1985) in the FAO-56 form as adopted by Allen et al. (1998), again with a daily resolution. [...] [::The water balance] for a given day was then calculated with a two-layer bucket model for a given soil water holding capacity as defined by the International Geosphere-Biosphere Programme (IGBP 2000).

Aims The aim of this study was to assess the impact of the developmental stage of naturally regenerated stone pine individuals on tolerance to low temperature (LT) from summer to late autumn and in spring, at a highly continental site in central Spain. Specifically, we tested to what extent the differences in tolerance are related to shoot heteroblasty. Methods We assessed LT tolerance of needles from individuals at three age classes (class C1: seedlings, class C2: 4- to 8-year-old saplings and class C3: {$>$}9-year-old saplings) over nine dates from summer to spring. Results LT tolerance displayed severe seasonal trends and differed between age classes. It usually increased with sapling age. Such differences were tightly related to heteroblasty of the shoots. Our results point to a higher LT tolerance associated with larger leaf dry mass per unit area (LMA) values. No impact of late frosts on shoot growth rates was detected during this study.

[Excerpt] [...] The document, a policy summary prepared by Working Group III of the IPCC, is the third instalment of the IPCC's Fifth Assessment Report. It follows reports on the science of climate and the impacts of climate change, released in the past few months. Compiled by hundreds of lead and reviewing authors over several years, the report warns that without substantial policy and technology changes, the world is heading towards dangerous temperature rises. Its focus is therefore on the technological and economic options for stabilizing atmospheric greenhouse-gas concentrations at acceptable levels. [...] The report, released at a packed press conference in a Berlin hotel, details how annual emissions have increased from 27 gigatonnes (Gt) of CO2 equivalent in 1970 to 49\,Gt in 2010 (see 'Who emits what?'). Emissions may now have reached more than 52\,Gt per year. The report adds that to have a 50\,\% chance of keeping the global surface-temperature increase below the UN target of 2\,\textdegree C, humans must not release more than an additional 1,550\,Gt of greenhouse gases before 2100. At current rates, that limit will be exceeded before 2050. The working group also warns that developed countries' emissions targets for 2020 -- agreed at a 2010 climate summit in Cancun, Mexico -- are inconsistent with the 2\,\textdegree C ceiling, which was set at the same summit. '' Meeting this goal would require further substantial reductions beyond 2020,'' the report finds. The IPCC also acknowledges that the renewable-energy industry is making substantial gains in performance and cost reductions. But it notes that growing global energy demand and an increase in coal's share of the global fuel mix in recent years threaten to thwart mitigation efforts. [...] Some researchers have long argued for a more pragmatic and diversified approach to climate change. For example, one group wrote in a policy paper in 2010 that fostering technological progress while focusing on poverty reduction -- an estimated 1.5 billion people have no access to electricity -- might ultimately prove more effective than international treaties such as the expired Kyoto Protocol on climate change (G. Prins et al. The Hartwell Paper; LSE, 2010).

In Scandinavia, it may be expected to expand inland from coastal areas if the warming climate trend continues. [::Habitat and Ecology] Taxus baccata is capable of growing under (not entirely closed) canopy of beech (Fagus spp.) as well as other deciduous broad-leaved trees, but it will only develop to large trees in more open situations. In Switzerland, the richest area of Central Europe for yew, it forms a yew-beech wood on cool, steep marl slopes in the Jura and the foothills of the Alps up to 1,400 m a.s.l. (Ellenberg 1988). Under the evergreen Common Yew, nothing else will grow. In England, T. baccata is best developed on chalk downs - again on steep slopes - and can form extensive stands outside the beech woods invading down grassland. In much of Europe where the climate is less oceanic it survives better in mixed forests, coniferous as well as mixed broad-leaved-conifer forests, again mostly on limestone substrates, and often occupying rocky cliffs and slopes. On acid soils yews perform less well under canopy and usually do not develop beyond a sapling stage in woods. Its northern limits in Scandinavia are determined by its sensitivity to severe frost. Its toxicity (all parts except the red arils around the seeds) prevent browsing by cattle and sheep, but not by rabbits and deer, as these animals have developed a level of immunity to the dangerous alkaloids. Apart from seed germination (dispersed by birds), T. baccata readily regenerates from stumps and roots (suckers); ancient hollow trees may rejuvenate constantly in this way. When planted, e.g. in church yards and cemeteries, soil pH seems unimportant; some of the largest and presumably oldest specimen trees in NW Europe, in particular Brittany (France) and the British Isles, are known from such locations and were planted probably since Celtic times [::Use and Trade] In the Middle Ages the wood of Common Yew was very much in demand for long-bows and cross-bows and was exported from Switzerland to England. Yews were also planted near sacred wells, early Christian churches, monasteries, and castles for symbolic/religious reasons as well as practical (military) ones. It still is one of the obligatory cemetery trees in NW and Central Europe. The hard, slow growing wood is used for gates, furniture, parquet floors, panelling, and is excellent for carving and wood turning as its contorted growth and 'burls' form intricate, vari-coloured patterns. For the same reasons yew does not provide timber suitable for construction. The toxicity to cattle and horses has led to extermination of Taxus baccata from many woodlands in past centuries, when almost all woodland served for grazing animals. Although of lower concentration than in some other species, its alkaloid taxanes, contained mostly in the leaves, yield a semi-synthesized anti-cancer drug similar to Taxol\textregistered{} and yew hedge clippings can still be sold to pharmaceutical companies. As an ornamental shrub or tree it reappeared in the formal gardens of the Baroque period, as it lends itself to clipped hedges and topiary of all shapes. This horticultural interest has in turn led to the development of numerous cultivars, some of which have bright yellow arils around the seeds. [::Major Threat(s)] Although in past centuries Yew has been 'persecuted' in much of Europe and it had become rare in many areas, with the changes in woodland management and use since the nineteenth century the species has made a remarkable come-back and is not in danger of extinction in the wild.}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-13621296,conservation,forest-resources,iucn,iucn-least-concern-lc,taxus-baccata}, lccn = {INRMM-MiD:c-13621296} }

[::] Conflicts on environmental consequences from bioenergy policy are reconcilable. [::] Conflicts on globally shared rights and responsibilities are not easily reconciled. [Abstract] Growing concerns over emissions of green-house gases causing climate change as well as energy security concerns have spurred the interest in bioenergy production pushed by EU targets to fulfil the goal of 20~per cent renewable energy in 2020, as well as the goal of 10~per cent renewable fuels in transport by 2020. Increased bioenergy production is also seen to have political and economic benefits for rural areas and farming regions in Europe and in the developing world. There are, however, conflicting views on the potential benefits of large scale bioenergy production, and recent debates have also drawn attention to a range of environmental and socio-economic issues that may arise in this respect. One of these challenges will be that of accommodating forest uses - including wood for energy, and resulting intensification of forest management - with biodiversity protection in order to meet EU policy goals. We note that the use of biomass and biofuels spans over several economic sector policy areas, which calls for assessing and integrating environmental concerns across forest, agriculture, energy and transport sectors. In this paper, we employ frame analysis to identify the arguments for promoting bioenergy and assess the potential policy conflicts in the relevant sectors, through the analytical lens of environmental policy integration. We conclude that while there is considerable leverage of environmental arguments in favour of bioenergy in the studied economic sectors, and potential synergies with other policy goals, environmental interest groups remain sceptical to just how bioenergy is currently being promoted. There is a highly polarised debate particularly relating to biofuel production. Based on our analysis, we discuss the potential for how those issues could be reconciled drawing on the frame conflict theory, distinguishing between policy disagreements and policy controversies.}, journal = {Forest Policy and Economics}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-11738844,~to-add-doi-URL,bioenergy,biomass,europe,forest-resources,ghg,science-policy-interface,uncertainty}, lccn = {INRMM-MiD:c-11738844} }

Here, we unveil the existence of opposite trends of recruitment limitation between the dominant genera Quercus and Pinus on a large scale and identify the key ecological drivers of these diverging trends. Location Spain Methods We gathered data from the Spanish National Forest inventory to assess recruitment trends for the dominant species (Pinus halepensis, Pinus pinea, Pinus pinaster, Pinus nigra, Pinus sylvestris, Pinus uncinata, Quercus suber, Quercus ilex, Quercus petraea, Quercus robur, Quercus faginea and Quercus pyrenaica). We assessed the direct and indirect drivers of recruitment by applying Bayesian structural equation modelling techniques. Results Severe limitations in recruitment were observed across extensive areas for all Pinus species studied, with recruitment failure affecting 54-71\,\% of the surveyed plots. In striking contrast, Quercus species expanded into 41\,\% of the plots surveyed compared to only 10\,\% for Pinus and had a lower local recruitment failure (29\,\% of Quercus localities compared to 63\,\% for Pinus species). Bayesian structural equation models highlighted the key role of the presence of Q.\,ilex saplings and the increase in the basal area of Q.\,ilex in limiting recruitment in five Pinus species. The recruitment of P.\,sylvestris and P.\,nigra showed the most negative trends and was negatively associated with the impacts of fire. Main conclusions This study identified Q.\,ilex, the most widespread species in this area, as a key driver of recruitment shifts on a large scale, negatively affecting most pine species with the advance of forest succession. These results highlight that the future expansion/contraction of Q.\,ilex stands with ongoing climate change will be a key process indirectly controlling the demographic responses of Pinus species in the Mediterranean Basin.}, journal = {Global Ecology and Biogeography}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-12651320,anthropogenic-changes,anthropogenic-unsustainable-species-distribution,climate-change,ecosystem-invasibility,forest-resources,global-warming,invasive-species,mediterranean-region,pinus-halepensis,pinus-nigra,pinus-pinaster,pinus-pinea,pinus-sylvestris,pinus-uncinata,plantation,potential-habitat,quercus-faginea,quercus-ilex,quercus-petraea,quercus-pyrenaica,quercus-robur,quercus-suber,spain,sustainability}, lccn = {INRMM-MiD:c-12651320} }

[Excerpt] [] [...] The transformation of research publishing is less a revolution and more a war of attrition. Battle lines were drawn long ago and all sides are well dug-in. In 2001, this journal published a series of viewpoints on the future of 'e-access to the primary literature' (see go.nature.com/pezj84). Those attitudes seem strikingly familiar today. At the time, the founders of the Public Library of Science initiative (then PLS, now reborn as the publisher PLoS) urged that research results should be stored in free, online, centralized repositories. Technology enthusiasts sang the praises of easy search and retrieval across a wide range of publication formats beyond the traditional journal article, but warned of the need for common standards. Publishers pointed out that someone would have to finance the publication of the increasing tide of information, and debated where revenue sources should come from. [] There was a voice missing from that debate: yours. More than a decade on, this journal's publisher, Nature Publishing Group (NPG), tried to remedy that by surveying more than 23,000 scientists about their experience of and opinions on open-access publishing. The key question is not just what scientists could have, but what they want. [...] [] One preliminary result that stands out is the diversity of experiences and attitudes across disciplines. In biology, 17\,\% of papers published by the respondents over the past three years had been immediately made free for all to read by paying the publisher up front, and more than half of the biologists surveyed said that they had published at least one such paper. In chemistry, the proportion of papers was just 4\,\%, and less than one-quarter of chemists had published at least one open-access paper. More than half of biologists felt that '' all papers should be published open-access'', whereas just under one-third of chemists agreed (the remaining one-third of chemists neither agreed nor disagreed). [] Nor do scientists hold consistent views about how widely information should be shared and reused. [...] [] [...] [] The dazzling variety of publishing options will fragment the information available on the web. Scholars need to think through how they would like that information to be shared and reused -- answers may be different for the various disciplines.

However, they possess different characteristics in terms of spatial detail or thematic accuracy. Little attention has been paid to the effect of these characteristics on simulation models and the resultant policy implications. In this study we tested whether the choice of a forest map has substantial influence on model output, i.e. if output differences can be related to the input differences. A sensitivity analysis of the spatially explicit Global Forest Model (G4M) was performed using four different forest maps: the pan-European high resolution forest/non-forest map (FMAP), the Corine Land Cover (CLC), the Calibrated European Forest Map (CEFM) and the Global Land Cover (GLC). Finally, the impact of potential differences owing to input datasets on decision-making was tested in a selected case study: reaching the EU 10\,\% biofuel target through enhanced utilization of forest biomass. The sensitivity analysis showed that the choice of the forest cover map has a major influence on the model outputs in particular at the country-level, while having less influence at the EU27 level. Differences between the input datasets are strongly reflected in the outputs. Similarly, depending on the choice of the input alternate options for decision-making were found within the hypothesized biofuel target (case study), demonstrating a substantial value of information. In general, it was demonstrated that input maps are the major driver of decision-making if forest resource outputs of the model are their basis.

Regardless of emission scenarios, it is universally expected that British Columbia will experience warmer air temperatures, coupled with more precipitation in some regions and less in others. Forest fires are expected to be more frequent and more intense in the southern half of the province and in the Taiga Plains, but less important in other portions of the province. Forest insects and fungal pathogens are expected to more fully occupy the current range of their host tree species and expand ranges northward and to higher elevations along with their hosts.

Although many of the contributing factors to the changed disease scenarios are anthropogenic, there has been a reluctance to control them by legislation, other forms of government authority or through public involvement. Some of the primary obstacles relate to problems in communicating biological understanding of concepts to the political sphere of society. Relevant response to new disease scenarios is very often associated with a proper understanding of intraspecific variation in the challenging pathogen. Other factors could be technical, based on a lack of understanding of possible countermeasures. There are also philosophical reasons, such as the view that forests are part of the natural ecosystems and should not be managed for natural disturbances such as disease outbreaks. Finally, some of the reasons are economic or political, such as a belief in free trade or reluctance to acknowledge supranational intervention control. Our possibilities to act in response to new disease threats are critically dependent on the timing of efforts.

Members of the genus Sambucus have a multitude of uses including: river bank stabilization and windbreaks (Paquet and Jutras 1996); wildlife food and refuge; ornamental, crafts and games; versatile human food source, and multi-purpose medicinal (Vall\`es et al. 2004). While the scientific documentation related to elderberries has increased over the last two decades, few reviews have been published. Martin and Mott (1997) reviewed the selection, cultivation, and management of American elderberry for wildlife and habitat management. More recently, the ecology of the European elderberry in the British Isles was thoroughly reviewed by Atkinson and Atkinson (2002). Finally, Charlebois (2007) reviewed the medicinal properties of elderberries, some of which were already mentioned in Dioscorides' Materia Medica written around the first century. Despite a well established commercial production in many countries of Europe and an increasing interest in North America, little attention has been paid to the horticultural aspects of this genus and its potential as a food and a medicinal crop. Recent works linking an antioxidant-rich diet to disease prevention (Prior 2003; Willcox et al. 2004; Scalbert et al. 2005; Zafra-Stone et al. 2007; Seeram 2008), along with the versatility of elderberry as a crop, a food, and a medicine, have generated a renewed interest in this genus.

By analyzing the model sensitivity to global-scale replacement of forests by grassland, it is shown that the surface albedo increase owing to deforestation has a cooling effect of -1.36 K globally. On the other hand, forest removal decreases evapotranspiration efficiency and decreases surface roughness, both leading to a global surface warming of 0.24 and 0.29 K, respectively. The net biogeophysical impact of deforestation results from the competition between these effects. Globally, the albedo effect is dominant because of its wider-scale impact, and the net biogeophysical impact of deforestation is thus a cooling of -1 K. Over land, the balance between the different processes varies with latitude. In temperate and boreal zones of the Northern Hemisphere the albedo effect is stronger and deforestation thus induces a cooling. Conversely, in the tropics the net impact of deforestation is a warming, because evapotranspiration efficiency and surface roughness provide the dominant influence. The authors also explore the importance of the ocean coupling in shaping the climate response to deforestation. First, the temperature over ocean responds to the land cover perturbation. Second, even the temperature change over land is greatly affected by the ocean coupling. By assuming fixed oceanic conditions, the net effect of deforestation, averaged over all land areas, is a warming, whereas taking into account the coupling with the ocean leads, on the contrary, to a net land cooling. Furthermore, it is shown that the main parameter involved in the coupling with the ocean is surface albedo. Indeed, a change in albedo modifies temperature and humidity in the whole troposphere, thus enabling the initially land-confined perturbation to be transferred to the ocean. Finally, the radiative forcing framework is discussed in the context of land cover change impact on climate. The experiments herein illustrate that deforestation triggers two opposite types of forcingmechanisms-radiative forcing (owing to surface albedo change) and nonradiative forcing (owing to change in evapotranspiration efficiency and surface roughness)-that exhibit a similar magnitude globally. However, when applying the radiative forcing concept, nonradiative processes are ignored, which may lead to a misrepresentation of land cover change impact on climate. [Excerpt: Conclusions] In this study we addressed the biogeophysical impact of deforestation with a fully coupled land-ocean-atmosphere GCM. We contrasted the climate of a maximally forested earth with the climate resulting from the replacement of forest by grass. Our experimental design allows us to separate the respective roles of surface albedo, evapotranspiration efficiency, and surface roughness in shaping the net biogeophysical effect of deforestation. Whereas our main focus here was on the energy budget and surface temperature, investigations of the response of the hydrological cycle will be conducted in the future. [\textbackslash n] Increase in surface albedo owing to complete deforestation has a cooling effect on climate (-1.36 K globally). On the other hand, forest removal decreases evapotranspiration efficiency and surface roughness, which warms surface climate (respectively, by 0.24 and 0.29 K globally). The magnitude of these different effects varies regionally. The cooling effect due to albedo change is stronger at high latitudes and affects both land and ocean. Conversely, the warming effect from change in evapotranspiration efficiency and surface roughness is stronger at low latitudes and does not affect the oceans. [\textbackslash n] The net biogeophysical impact of deforestation results from the competition between these effects. Globally, the albedo effect is dominant and the net biogeophysical impact of deforestation is a cooling of -1 K. This is mainly because the albedo effect spreads over the ocean, whereas the other effects do not. On continents, however, the balance between the different processes changes with latitude. In temperate and boreal zones of the Northern Hemisphere the albedo effect is stronger and deforestation thus induces a cooling, as has already been noticed in previous studies (e.g., Betts 2001; Bounoua et al. 2002). Conversely, in the tropics the net impact of deforestation is a warming because evapotranspiration efficiency and surface roughness provide the dominant influence in these regions. [\textbackslash n] This study also highlights the importance of the coupling with the ocean. Up to now, most of our knowledge concerning the impact of land cover change on climate comes from atmospheric models not coupled to an ocean model but instead assuming fixed oceanic conditions (e.g., Dickinson and Henderson-Sellers 1988; Nobre et al. 1991; Bonan 1997; Lean and Rowntree 1997; Chase et al. 2000; Gedney and Valdes 2000; Betts 2001; Bounoua et al. 2002; DeFries et al. 2002; Voldoire 2006). Implicitly, this assumption was justified be the fact that the perturbation owing to land cover change is applied to land and not to the ocean. However, our experiments show that taking into account the coupling with the ocean greatly affect the simulated response to deforestation. First, we noted that the ocean surface responds to deforestation by a cooling. Second, even the temperature change over land is strongly affected by the ocean coupling. By not taking into account the coupling with the ocean we would have concluded that the net effect of deforestation, averaged over all land areas, is a warming. By accounting for the ocean coupling, this net effect is of opposite sign. We also further demonstrated that the main parameter involved in the coupling with the ocean is surface albedo. This is because change in albedo modifies temperature and humidity in the whole troposphere, thus enabling the initially land-confined perturbation to be transferred to the ocean. [\textbackslash n] Finally, the results presented here give some insight concerning the nature of the forcing owing to land cover change. Supporting earlier hypothesis (Pielke et al. 2002; NRC 2005; Davin et al. 2007), we showed that deforestation involves two opposite types of forcing mechanisms: a radiative forcing (owing to surface albedo change) and a nonradiative forcing (owing to change in evapotranspiration efficiency and surface roughness). We quantified the relative importance of these opposite forcings in the context of our complete deforestation experiments and found that, globally, they are of similar magnitude. This result highlights the limitation of the classical radiative forcing framework in which equilibrium temperature change is viewed as a response to a radiative forcing perturbation. Land cover change can also affect equilibrium temperature through nonradiative processes. Historical deforestation took place mostly in temperate regions, and therefore radiative forcing was roughly acceptable in quantifying its effect. Future deforestation, however, is expected to take place in the tropics where nonradiative effects are dominant. Hence, using the radiative forcing framework in the context of future land cover change may lead to a misrepresentation of its impact on climate.}, journal = {Journal of Climate}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-6519442,~to-add-doi-URL,albedo,boreal-forests,climate,complexity,deforestation,evapotranspiration,feedback,forest-resources,global-climate-models,humidity,land-cover,large-vs-wide-scale,oceans,off-site-effects,surface-roughness,temperate-forests,temperature,trade-offs,tropical-forests,wide-scale}, lccn = {INRMM-MiD:c-6519442}, number = {1} }

Soils, topography, surficial geology, and hydrology determine the capability of forest buffers to intercept and treat these flows. This paper describes two landscape analysis techniques for identifying and mapping locations where agroforestry buffers can effectively improve water quality. One technique employs soil survey information to rank soil map units for how effectively a buffer, when sited on them, would trap sediment from adjacent cropped fields. Results allow soil map units to be compared for relative effectiveness of buffers for improving water quality and, thereby, to prioritize locations for buffer establishment. A second technique uses topographic and streamflow information to help identify locations where buffers are most likely to intercept water moving towards streams. For example, the topographic wetness index, an indicator of potential soil saturation on given terrain, identifies where buffers can readily intercept surface runoff and/or shallow groundwater flows. Maps based on this index can be useful for site-specific buffer placement at farm and small-watershed scales. A case study utilizing this technique shows that riparian forests likely have the greatest potential to improve water quality along first-order streams, rather than larger streams. The two methods are complementary and could be combined, pending the outcome of future research. Both approaches also use data that are publicly available in the US. The information can guide projects and programs at scales ranging from farm-scale planning to regional policy implementation.}, journal = {Agroforestry Systems}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-13618239,agroforestry,flow-accumulation,forest-resources,integration-techniques,riparian-zones,sediment-transport,soil-erosion,soil-resources,spatial-prioritization,topographic-wetness-index,vegetation-buffer,water-quality,water-resources}, lccn = {INRMM-MiD:c-13618239}, number = {1} }

Using rain gage and response data from five fires in Colorado and southern California, we document the rainfall conditions that have triggered post-fire debris flows and develop empirical rainfall intensity-duration thresholds for the occurrence of debris flows and floods following wildfires in these settings. This information can provide guidance for warning systems and planning for emergency response in similar settings. Debris flows were produced from 25 recently burned basins in Colorado in response to 13 short-duration, high-intensity convective storms. Debris flows were triggered after as little as six to 10~min of storm rainfall. About 80\,\% of the storms that generated debris flows lasted less than 3~h, with most of the rain falling in less than 1~h. The storms triggering debris flows ranged in average intensity between 1.0 and 32.0~mm/h, and had recurrence intervals of two years or less. Threshold rainfall conditions for floods and debris flows sufficiently large to pose threats to life and property from recently burned areas in south-central, and southwestern, Colorado are defined by: I~=~6.5D-~0.7 and I~=~9.5D-~0.7, respectively, where I~=~rainfall intensity (in mm/h) and D~=~duration (in hours). Debris flows were generated from 68 recently burned areas in southern California in response to long-duration frontal storms. The flows occurred after as little as two hours, and up to 16~h, of low-intensity (2-10~mm/h) rainfall. The storms lasted between 5.5 and 33~h, with average intensities between 1.3 and 20.4~mm/h, and had recurrence intervals of two years or less. Threshold rainfall conditions for life- and property-threatening floods and debris flows during the first winter season following fires in Ventura County, and in the San Bernardino, San Gabriel and San Jacinto Mountains of southern California are defined by I~=~12.5D-0.4, and I~=~7.2D-0.4, respectively. A threshold defined for flood and debris-flow conditions following a year of vegetative recovery and sediment removal for the San Bernardino, San Gabriel and San Jacinto Mountains of I~=~14.0D-0.5 is approximately 25~mm/h higher than that developed for the first year following fires.

Forests are particularly sensitive to climate change, because the long life-span of trees does not allow for rapid adaptation to environmental changes. Adaptation measures for forestry need to be planned well in advance of expected changes in growing conditions because the forests regenerated today will have to cope with the future climate conditions of at least several decades, often even more than 100 years.

We argue that, although improved accuracy can be delivered through the traditional tasks of trying to build better models with improved data, more robust forecasts can also be achieved if ensemble forecasts are produced and analysed appropriately.}, journal = {Trends in Ecology \& Evolution}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-1030028,consensus,ensemble,modelling,robust-modelling,species-distribution,uncertainty}, lccn = {INRMM-MiD:c-1030028}, number = {1} }

Annual courses of photosynthesis ( A max ), stomatal conductance ( g s ), electron transport rate (ETR) and chlorophyll levels were compared between 2003 and 2004, the latter year representing the humid long-term climate at the site. ETR, A max and g s were lowered during 2003 by drought rather than ozone, whereas chlorophyll levels did not differ between the years.

Comparison of AOT40, an O 3 exposure-based risk index of O 3 stress, and cumulative ozone uptake (COU) yielded a linear relationship throughout humid growth conditions, but a changing slope during 2003. Our findings support the hypothesis that drought protects plants from O 3 injury by stomatal closure, which restricts O 3 influx into leaves and decouples COU from high external ozone levels.

Therefore, the first objective of this study was to quantify the velocities, rebound heights as well as the residual hazard of rockfall on a forested and a non-forested slope. The second objective was to evaluate existing rockfall protection forest management guidelines, as well as the underlying criteria. We carried out and analysed 100 real size rockfall experiments at a non-forested site (Site 1) and 102 identical experiments at a forested site (Site 2) on the same slope. We compared the obtained results with literature data on rockfall protection forests. At the non-forested site, results show that the mean maximum velocity is 15.4 m s-1 compared to 11.7 m s-1 at the forested site. The maximum rebound height decreases from 8 m (Site 1) to 2 m (Site 2) and the number of rocks that surpass the 223.5 m slope distance decreases from 95 out of 100 (Site 1) to 35 out of 102 (Site 2). A major effect of rockfall on a forested slope is the development of a treeless rockfall path or couloir, which had evolved after releasing 78 rocks at Site 2. The effect of such a couloir can be mitigated by cutting trees on both sides of the couloir and leaving the trunks on the slope, diagonally to the slope direction. This is a known and effective technique to reduce the effect of gaps in protection forests. During our experiments, none of the rocks attained their maximal velocity within the first 40 m. They did, however, attain destructive velocities (11-15 m s-1) within that distance. Based on our observations, we propose a maximum gap size in the slope direction of 1.3 times the mean tree height, with a maximum of 40 m. Further, we present various findings that have direct implications for the management of rockfall protection forests. Finally, the results proved that forests can provide effective protection against rockfall.}, journal = {Forest Ecology and Management}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-13618014,abies-alba,acer-pseudoplatanus,comparison,disturbances,fagus-sylvatica,forest-resources,landslides,larix-decidua,picea-abies,quercus-robur,rockfalls}, lccn = {INRMM-MiD:c-13618014}, number = {1-3} }

We assessed, for the first time, the ability of existing reserve-selection methods to secure species in a climate-change context. Six methods using a different combination of criteria (representation, suitability and reserve clustering) are compared. The assessment is carried out using European distributions of 1200 plant species and considering two extreme scenarios of response to climate change: no dispersal and universal dispersal. With our data, 6-11\,\% of species modelled would be potentially lost from selected reserves in a 50-year period. Measured uncertainties varied in 6\,\% being 1-3\,\% attributed to dispersal assumptions and 2-5\,\% to the choice of reserve-selection method. Suitability approaches to reserve selection performed best, while reserve clustering performed poorly. We also found that 5\,\% of species modelled would lose their entire climatic envelope in the studied area; 2\,\% of the species modelled would have nonoverlapping distributions; 93\,\% of the species modelled would maintain varying levels of overlapping distributions. We conclude there are opportunities to minimize species' extinctions within reserves but new approaches are needed to account for impacts of climate change on species; especially for those projected to have temporally nonoverlapping distributions.}, journal = {Global Change Biology}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-201812,~to-add-doi-URL,climate-change,clustering,conservation,europe,species-dispersal,species-distribution,uncertainty}, lccn = {INRMM-MiD:c-201812}, number = {9} }
@techreport{wolfEUFORGENTechnicalGuidelines2003, title = {{{EUFORGEN Technical}} Guidelines for Genetic Conservation and Use for Silver Fir ({{Abies}} Alba)}, author = {Wolf, Heino}, year = {2003}, pages = {6}, address = {{Rome, Italy}}, institution = {{EUFORGEN}}, abstract = {Since silver fir stands have been regenerated mainly naturally for a long period, there is reason to assume that they have preserved their original genetic structure and diversity, although the genetic composition of silver populations may have been modified by adaptation and/or drift processes. It is evident that in several parts of the distribution area genetic variation has been reduced due to the mentioned decline of silver fir. This reduction of population sizes may have reached a stage where the future survival of locally remnant populations is no longer guaranteed. [] To preserve the population-specific genetic structures of silver fir, i.e. locally common alleles and the area-specific allele frequency distribution, many different populations from various distribution areas should be selected systematically for gene conservation purposes. The most effective way to conserve larger occurrences of silver fir and their genetic resources is through in situ conservation of stands and populations as well as their natural regeneration using long-term and small-scale regeneration methods. Additional activities are the promotion of silver fir individuals by tending and thinning, and the strict control of game. If planting of silver fir is required, culling for height of plants in the nursery should be avoided since genetic effects of this procedure cannot be excluded. In case of occurrences with a low number of individuals, enrichment planting in addition to the natural regeneration is recommended with plants from other, larger occurrences of the same region to avoid a higher frequency of half-sib offsprings and subsequent inbreeding in the next regeneration stage. [] To avoid risks of interspecific geneflow, reforestation using exotic Abies species in the vicinity of silver fir stands should be strictly monitored. Only in marginal areas, with highly depleted genepools and where ecological conditions are very degraded could interspecific mating help to create new adapted genotypes. In all other cases, it should be avoided. For small populations with a decreased number of individuals, and in addition to in situ conservation measures, the establishment of ex situ gene conservation seed orchards is highly recommended in order to overcome the isolation of individuals and to promote outcrossing. The sampling of single trees does not affect the genetic structure if a sufficient number of individuals is considered. However, sampling should be done exclusively in indigenous populations, randomly in respect to the phenotype but representatively in respect to ecological variation. Wherever possible, the genotype of the individuals sampled should be assessed and considered, e.g. using gene markers to avoid loss of genetic variation and a reduced diversity. Complementary to in situ and ex situ conservation measures, seeds of silver fir can be stored in genebanks for about 3 to 5 years provided that outcrossing has taken place among a minimum number of 20 individuals. To overcome the negative effects of isolation in silver fir relicts in the short term, the collection and storage of pollen in combination with artificial pollination of mature trees could be an efficient but expensive approach. [] In the European Community, silver fir is under the EU Directive on the marketing of forest reproductive material. For reforestation or re-introduction of silver fir, only forest reproductive materials are to be used according to the regulations and must be suitable for the site conditions in question. In nations not under EU law, the procurement of forest reproductive material should follow the principles of approval, identification and control. In every case, however, recommendations should be developed for the proper use of forest reproductive material.}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-14257293,conservation,forest-resources,quercus-suber}, lccn = {INRMM-MiD:c-14257293} }

Our view incorporates the modeling and simulation phases that are recognized in the systems engineering and operations research communities, but it adds phases that are specific to the numerical solution of PDEs. In each of these phases, general sources of uncertainty, both aleatory and epistemic, and error are identified. Our general framework is applicable to any numerical discretization procedure for solving ODEs or PDEs. To demonstrate this framework, we describe a system-level example: the flight of an unguided, rocket-boosted, aircraft-launched missile. This example is discussed in detail at each of the six phases of modeling and simulation. Two alternative models of the flight dynamics are considered, along with aleatory uncertainty of the initial mass of the missile and epistemic uncertainty in the thrust of the rocket motor. We also investigate the interaction of modeling uncertainties and numerical integration error in the solution of the ordinary differential equations for the flight dynamics.}, journal = {Reliability Engineering \& System Safety}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-6210431,complexity,computational-science,modelling,software-engineering,software-errors,software-uncertainty}, lccn = {INRMM-MiD:c-6210431}, number = {3} }

@inproceedings{weissTopographicPositionLandforms2001, title = {Topographic Position and Landforms Analysis}, booktitle = {{{ESRI International User Conference}}}, author = {Weiss, Andrew D.}, year = {2001}, abstract = {[Excerpt: Introduction] Many physical and biological processes acting on the landscape are highly correlated with topographic position: a hilltop, valley bottom, exposed ridge, flat plain, upper or lower slope, and so on. Examples of these processes include soil erosion and deposition; hydrological balance and response; wind exposure; and cold air drainage. These biophysical attributes in turn are key predictors of habitat suitability, community composition, and species distribution and abundance. This poster presents an algorithm, implemented in GRID, for generating a multi-scale Topographic Position Index, classifying this index into slope position and landform types, and using the Topographic Position Index to characterize watersheds. This work was done as a contractor with U.S. EPA Region 10, working on the Environmental Monitoring and Asssessment Program Western Landscape Project (Jones et al 2000). [] [...] [Basic Algorithm] The Topographic Position Index (TPI) compares the elevation of each cell in a DEM to the mean elevation of a specified neighborhood around that cell (Fig. 2a). In this example an annulus neighborhood is used, but continuous circles or other shapes could be used. Since the only input required is a digital elevation model, TPI can be readily generated almost anywhere. Positive TPI values represent locations that are higher than the average of their surroundings, as defined by the neighborhood (ridges). Negative TPI values represent locations that are lower than their surroundings (valleys). TPI values near zero are either flat areas (where the slope is near zero) or areas of constant slope (where the slope of the point is significantly greater than zero). Topographic position is an inherently scale-dependent phenomenon. As an example, consider a location in a meadow in Yosemite valley. At a fine scale of 100m, the topographic position would be a flat plain. This may be an appropriate scale for looking at soil transport or site water balance. At a scale of several kilometers, this same point is at the bottom of a 1500m deep canyon, which may be more significant for overall hydrology, mesoclimate, wind exposure, or cold air drainage. The ecological characteristics of a site may be affected by TPI at several scales. In a study of vegetation distributions in the Spring Mountains of southern Nevada (Guisan, Weiss, and Weiss 1999) species distribution models show significant relationships to TPI at scales of 300m, 1000m, and 2000m. TPI was generally second most important predictive variable after elevation.

We identified six categories of fragmentation (interior, perforated, edge, transitional, patch, and undetermined) from the amount of forest and its occurrence as adjacent forest pixels. Interior forest exists only at relatively small scales; at larger scales, forests are dominated by edge and patch conditions. At the smallest scale, there were significant differences in fragmentation among continents; within continents, there were significant differences among individual forest types. Tropical rain forest fragmentation was most severe in North America and least severe in Europe-Asia. Forest types with a high percentage of perforated conditions were mainly in North America (five types) and Europe-Asia (four types), in both temperate and subtropical regions. Transitional and patch conditions were most common in 11 forest types, of which only a few would be considered as "naturally patchy" (e.g., dry woodland).

Factors shaping seedfall patterns have been typically explored from the tree perspective (seed shadow) or from the population perspective (seed rain). However, the seed rain is actually composed of multiple seed shadows. In this paper, we use this framework to explore the variables shaping the seedfall pattern of the wild olive tree (Olea europaea var. sylvestris), a fleshy-fruited tree of the Mediterranean scrublands. We monitored the movement patterns of avian seed dispersers and the seedfall around each fruit-bearing O. europaea tree in two contrasting sites, differing in the degree of human management and abundance of scrub cover. None of the seed dispersers moved between microhabitats (different shrub species and open interspaces) as a function of microhabitat relative abundance. All dispersers foraged preferentially at O. europaea; only the smaller species visited open interspaces, and these only sporadically. Avoidance of open sites by frugivores, especially larger species, and their attraction to source trees were the major determinants of the seedfall pattern. Regarding seed size distribution among microhabitats, we found that only small seeds were significantly overrepresented in open interspaces. From the seed shadow perspective, seed density under trees was similar in the two study sites, but it decreased with distance at a higher rate in the disturbed scrubland. From the seed rain perspective, seed density was significantly different among microhabitats, with open interspaces collecting few, if any, seeds, and places under source trees receiving the highest densities. Results from seed shadow and seed rain analyses were integrated to construct a path model to explore the relative contribution of spatial, microhabitat, and individual tree features to the seedfall pattern. Factors related to microhabitat were identified as having a major role in shaping seedfall pattern. Open interspaces collected few seeds, points under shrub species with sparse foliage collected moderate seed densities, and points under shrubs with dense foliage collected the highest seed densities. The comparison between sites suggests that habitat alteration (a reduction of the scrub layer) can lead to contrasting seedfall patterns. The occurrence of an abundant scrub layer in the well-preserved scrubland allowed a complex pattern of seed rain. In contrast, the sparse scrub cover in the disturbed scrubland yielded a seedfall pattern composed of multiple seed shadows constrained to the vicinity of tree crowns. Thus, our sampling design and analytical approach have proved useful in describing the relative importance of the set of variables that shapes the complex seedfall pattern of a bird-dispersed plant. This seedfall pattern, in turn, is central to the understanding of the spatial patterns of plant recruitment and the efficiency of the dispersal mutualism.}, journal = {Ecology}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-13593951,bird-dispersal,forest-resources,seed-dispersal,tree-ecology}, lccn = {INRMM-MiD:c-13593951}, number = {7} }

Ninety-five \% confidence intervals ranged from 5 to \% . Estimated sample sizes varied greatly. The value of knowing the live fuel moisture content in fire decision making is unknown. If the fuel moisture is highly variable, then it is possible for the confidence intervals to span one or more fire behavior or danger classes. Errors in live fuel moisture data may directly affect the costs in safety and resources associated with prescribed fire and wildfire suppression. [Excerpt: Fire management implications] As pointed out in the Live Fuel Moisture Task Force Report (Cohen et al. 1995), live fuel moisture information is currently best used in strategic decisions instead of tactical decisions because of the current limitations in our understanding of live fuels and fire behavior. Since the 1940's,live fuel moisture information has been used in fire danger calculations, a strategic level use of the data. In the first version of the National Fire-Danger Rating System (NFDRS), live fuel moisture was sampled along transects at each fire danger station. This approach was replaced by live fuel moisture models for herbaceous and shrub fuels in the 1978 NFDRS (Bradshaw et al. 1983). The 1978 NFDRS live fuel moisture model transfers herbaceous fuels into the 1-hour timelag fuel class; however, live woody fuels are not transferred into the corresponding dead fuel classes. Live fuels can still contribute heat to the combustion process (Richards 1940, Bradshaw et al. 1983). [] Some users of live fuel moisture information have used the data to develop general guidelines related to fire behavior and danger (Cohen et al. 1995). Monitoring live fuel moisture data over several years has enabled others to use the data to estimate what the current fire danger is relative to previous years' fire danger. By developing an '' average'' annual live fuel moisture profile, a fire management agency can make these fire danger assessments. [...] However, error associated with live fuel moisture samples should be considered when using live fuel moisture data in this fashion. [] Consider the following example. The confidence intervals for chamise at Boquet Canyon 1 were roughly {$\pm$}40\,\% and at San Marcos were roughly {$\pm$}10\,\%. [] Assume guidelines such as: [::1)] live fuel moisture {$>$} 120\,\%-low fire danger; [::2)] 80\,\% {$<$} live fuel moisture {$<$} 120\,\%-moderate fire danger; [::3)] 60\,\% {$<$} live fuel moisture 80\,\%-high fire danger; and [::4)] live fuel moisture {$<$} 60\,\%-extreme fire danger; [] have been developed. [] If live fuel moisture is estimated to be 90\,\%, fire danger would be rated anywhere from low to extreme at Boquet and moderate at San Marcos because of the width of the confidence intervals. This may have serious implications for fire management applications. [...] [Summary] The variation associated with sampling live fuel moisture was examined for several shrub and canopy fuels in southern California, Arizona, and Colorado. Ninety-five \% confidence intervals ranged from {$\pm$}5\,\% to {$\pm$} 100\,\%. Estimated sample sizes also varied greatly. At allowable error of 5\,\%, maximum mean estimated sample size was as high as 630. Increasing allowable error to 25\,\% reduced estimated sample sizes to less than 30. [] The value of live fuel moisture in fire decision making is unknown. If the fuel moisture is highly variable, then it is possible for the confidence intervals to span one or more fire behavior or dangers classes. Errors in live fuel moisture data may directly affect the costs in safety and resources associated with prescribed fire and wildfire suppression. If live fuel moisture content is to be sampled to provide information for fire management decisions, care should be taken to collect an adequate sample to insure that the precision of the estimate is within acceptable bounds.

Die Gattung wird - gemeinsam mit den eng verwandten Gattungen Microtropis WALL. und Glyptopetalum THWAITES der Unterfamilie Celastroideae, Tribus Euonymeae zugeordnet. Sie unterteilt sich in zwei Subgenera (Euonymus und Kalonymus), welche sich wiederum in mehrere Sektionen und Reihen aufgliedern lassen. Die folgenden Merkmale gelten als gattungsspezifisch: Meist aufrechte, in einigen F\"allen auch niederliegende und sehr selten kletternde Str\"aucher, oft mit vierkantigen Zweigen, gegenst\"andigen (Ausnahme: E. nanus), ungeteilten und kahlen Bl\"attern. Die vier- bis f\"unfz\"ahligen, gr\"unlichen Bl\"uten fallen wenig auf und stehen in Bl\"utenst\"anden, welche den Achseln von Laub- oder Niederbl\"attern entspringen. Die Staubbl\"atter sitzen auf einem rel. gro\ss en, fl\"achigen, Nektar absondernden Diskus (hypostaminater D.). Euonymus-Arten bilden kantige, drei- bis f\"unff\"achrige Kapselfr\"uchte aus.

The vegetation cover of the floodplain depends on topographical levels which govern the frequency and duration of submergence during flooding. Along the valley, forest patches vary from a continuous ribbon of riparian wood along the river to a mosaic of groves towards the upland terraces. In the floodplain, the forest dynamics are influenced by floods, appear to be reversible, and are subject to dominant allogenic processes. On the contrary, forest dynamics on the terraces, which are not influenced by floods, are irreversible and subjected to dominant autogenic processes. Since the end of the 17th century, the structure of riparian woods has been modified by navigation and agriculture leading to a fragmentation of forest cover in the floodplain. Modern agriculture and urbanization have accentuated these tendencies by modifying the hydrologic regime of the river. These historical changes result in a fragmentation of forest cover and a substitution of species in the riparian zone, the forest dynamics being still reversible in the floodplain.}, journal = {Landscape Ecology}, keywords = {*imported-from-citeulike-INRMM,~INRMM-MiD:c-13544889,floodplain-forests,forest-conservation,river-restoration}, lccn = {INRMM-MiD:c-13544889}, number = {3} }

Following a short review of past attempts and proposals in this field, a format for model description is presented. The prototype inventory has been implemented on a personal computer, using a common commercial DBMS. Some advantages and problems of this implementation are also discussed in the paper. Furthermore, an attempt is made to identify the basic features of a user-friendly interface for the data base in order to allow the non-computer-oriented users to easily access and extract information from the inventory.
