Differential responses of ecosystem components to a low-intensity fire in a Mediterranean forest: a three-year case study. García-Tejero, S., Taboada, Á., Tárrega, R., Salgado, J., & Marcos, E. Community Ecology, 14(1):110--120, June, 2013.
Paper doi abstract bibtex Mediterranean forests are especially prone to fire, a periodic disturbance that affects all the ecosystem components in different ways. Gathering knowledge on the particular responses and rate of recovery of multiple ecosystem components following a wildfire is crucial to reliably evaluate its consequences on biodiversity. Using eight sampling transects, we studied the changes in four ecosystem components (topsoil, plants, carabids, and staphylinids) during three years after a spring wildfire in a Quercus pyrenaica forest; and compared them with the surrounding unburnt forest (hereafter control). We found great variety of responses to fire suggesting each component may deal with this recurring disturbance via different adaptations, and that the time spent to recover to pre-disturbance conditions depends on the group of focus. Topsoil characteristics were highly variable and minor differences were found between burnt and control transects. Plant community was considerably affected by fire but rapidly recovered exceeding the control forest in species richness and cover, partly due to proliferation of annual herbs. However, plant species composition differed between burnt and control forests during the whole study period.

[Conclusions]
The wildfire had different effects on the ecosystem components
studied. While topsoil features hardly differed between
control and burnt transects, plant community was
greatly affected by fire, although it almost recovered to prefire
conditions during the following years, mainly due to resprouting
of woody species. During the second and third
years, annual herbs proliferated thanks to reduced competition,
producing a good yield of seeds which may have fed the
carabid seed predators that colonised the warm and dry burnt
transects during that period, therefore increasing overall
carabid richness and abundance. Staphylinid beetles were
mostly negatively affected by fire during the first two years,
maybe due to a decrease in the number or quality of the microhabitats
they require to feed and reproduce, but their assemblages
approached those of the control transects during
the third sampling year. For carabids and staphylinids, control
transects were spatially more different than the burnt
ones as the possible pre-existing differences between burnt
transects could have been overcome due to the homogenising
effect of fire. All these patterns underline the fact that spring
fires in Mediterranean oak forests may help to maintain the
spatial heterogeneity typical of traditional management practices
to which the ecosystem components are adapted (see
Hj\"{a}lt\'{e}n et al. 2010). In this sense, vegetation rapidly recovered
by autosuccession, carabids increased their abundance
and species richness and, together with staphylinids, they developed
different assemblages from those of the unburnt surrounding forest thus enhancing biodiversity at the landscape
scale.},
