| Summary: | (Uploaded by Plazi for the Bat Literature Project) Freshwater systems have been profoundly changed by the construction of dams, and the influence of dams on bat activity is poorly understood. In this study, we analyzed the effects of small dams along mountain streams on local bat communities. This work was carried out in five small streams located in the NE of Portugal using bioacoustic surveys during the summer of 2011. The present study confirms that, in the northeast areas of Portugal, the majority of bat species use artificial bodies of water for either drinking or foraging, but species differed in terms of their activity levels over the reservoirs when compared with intact stream habitats. As predicted, small dams in the study area were important centers of overall bat activity relative to other sampling areas. At the same time, feeding activity was also higher in the flooded areas. We also found that Pipistrellus pipistrellus, Myotis daubentonii, Pipistrellus kuhlii, Pipistrellus pygmaeus/Miniopterus ... |
