| Summary: | Understanding how the spatial distribution of ecological resources shape species’ diversity and abundance in human-modified landscapes is a central theme in conservation biology. However, studies often disregard that such patterns may vary over time, thereby potentially missing critical environmental constraints to species persistence. This may be particularly important in highly mobile species such as bats, which are able to track temporal variations in spatial resource distribution. Here we test the hypothesis that bats in Mediterranean landscapes are strongly affected by the progressive reduction in water availability during the seasonal summer drought. We analysed the effects of landscape composition and structure on bat diversity and activity, during Pregnancy, Lactation and Post-lactation periods, and identified the most influential variables within and across periods. Water bodies showed the strongest positive effect on bats, followed by riparian habitats and areas with steeper (>30%) slopes. ... : Data with transect information, including response variables and predictorsIn this data file, you can find transect identifier (Transect), sampling year and season, as well as all the predictors and response variables. Predictors are scaled and weighted according to transect area. Predictors: alt_stdev (Altitude standard deviation); slp_range (slope range); s30 (Slopes stepper than 30º); nort.media (northness median); east.media (eastness median); NP_C (number of closed patches); ED_C (edge density closed patches); AREA_MN_C (mean area of closed patches); PR_C (closed patches richness); NP_O (number of open patches); ED_O (edge density open patches); AREA_MN_O (mean area of open patches); PR_O (open patches richness). Species: Bbar (Barbastella barbastellus), Eser.Eisa (Eptesicus serotinus, E. isabellinus); Eser.Eisa.Nlei (Eptesicus serotinus, E. isabellinus, Nyctalus leisleri); Mdau (Myotis daubentonii); Mesc (M. escalerai); Mmyo.Mbly (M. Myotis, M. blythii); Msmall (small Myotis group – M. daubentonii, M. ... |
