摘要: Aim We deconstructed the mammal species richness pattern in Europe to assess importance of large-scale gradients current macroclimate relative biogeographic history, habitat heterogeneity and human influence (HHH variables) as determinants for total species, widespread endemic separately. Location Europe, west 30° E. Methods (50-km resolution) into its components. used simultaneous autoregressive modelling (SAR) with information-theoretic model selection variation partitioning HHH variables. The variables included two historical factors, estimated by novel methodologies: (1) ice-age-driven dynamics, represented accessibility recolonization from hindcasting-estimated glacial refugia, (2) peninsular distance entry region main European faunal source western Asia. Results A large fraction explained was shared between SAR models. For richness, more could be uniquely attributed than HHH, whereas patterns (widespread species) opposite case. Considering individual there a strong peninsula effect on both but not richness. Main conclusions Both (history, influence) proved important predictors also difficult disentangle. Notably, particular is an determinant richness.
