Species richness and turnover patterns in European tenebrionid beetles

摘要: We used a hyperdiverse invertebrate group, tenebrionid beetles, to test competing hypotheses about the factors correlated with spatial variation in spe- cies richness and composition across Europe. 2. considered following for explaining species rich- ness, (i) heterogeneity, (ii) environmental energy, (iii) dispersal limitation post-glacial recolonisation, composition, current climate, Pleistocene glaciations, neutral dynam- ics. 3. inventories of 36 European territories, built from database contain- ing distributions 1010 or subspecies. Area, position, topo- graphical climatic variables were as predictors regression (richness) constrained analysis principal coordinates (composition) analyses. 4. The latitudinal gradient found tenebrionids was mostly explained by joint effect variables, supporting climate incomplete recolonisation hypotheses. 5. A parabolic relationship endemism longitude points presence centres Iberian Peninsula Balkans. Current con- ditions alone not sufficient explain turnover patterns tenebrionids, which are largely influenced factors. 6. Both glaciations supported, but fact that is uniform Europe suggests historical effects had deeper impact on assemblages than dynamics. Thus, seems more directly controlled cli- matic factors, whereas geographical constraints related sto- chastic colonisation events composition.
