	abstract = {The damming of rivers and streams alters downstream habitat characteristics and biotic assemblages, and might thus alter stream functioning, although there is not much direct evidence of this impact. In this study we compared breakdown of alder leaves upstream and downstream from 4 small ({\textless}1 hm3) dams in 4 Mediterranean mountain streams with no appreciable impact on water temperature and nutrient concentrations. Despite no effect on water characteristics, dams decreased leaf litter breakdown rates. Abundance and biomass of invertebrates and shredders and hyphomycete sporulation rates did not differ between upstream and downstream bags. However, the structure of invertebrate and hyphomycete assemblages did. Especially evident was a drop in limnephilids, which might explain the slower breakdown of leaf litter below dams. These results may help to explain some of the variability found in the literature on the effects of dams on decomposition rates. If dams increase water temperature and nutrient concentrations they may promote faster decomposition, but if dams do not change water characteristics, their impact on detritivore communities may cause slower decomposition rates.},
