Aim. Historical climate variations, current climate and human impacts are known to influence current species richness, but their effects on phylogenetic and trait diversity have been seldom studied. We investigated the relationship of these three factors with the independent variations of species, phylogenetic and trait diversity of European mammals. Considering the position of the 0ºC isotherm in the Last Glacial Maximum as a tipping point, we tested the following hypotheses: northern European assemblages host less species than southern European ones; northern areas harbour trait and phylogenetically clustered assemblages, while the more stable southern areas host random or overdispersed assemblages; and, species richness increases with human influence, while phylogenetic and trait diversity show clustered patterns in areas with stronger human influence. Location. Western Palearctic. Time period. Current and Late-Pleistocene effects on present-day diversity. Major taxa studied. Terrestrial mammals. Methods. ... : Data on the distribution of native terrestrial (both volant and non-volant) mammal species were obtained from IUCN (2016), using a 100 km equal-area grid (i.e. with 10,000 km2 cells) encompassing the whole Western Palearctic, i.e. both Europe and the Mediterranean region (European grid, based on the ETRS89 Lambert Azimuthal Equal-Area projection; it also includes the Mediterranean Islands and Northern Africa). This region hosts 357 mammal species, which constitute the regional pool of species that can potentially colonise any grid cell, and therefore were used as the source pool for all community assembly analyses described below. The extent of the analyses was limited to mainland Europe (comprising Great Britain and Russia up to the Ural Mountains), the Anatolian Peninsula, Syria and Israel. In total, these territories host 354 mammal species. We excluded cells that had less than 95% of land surface. Species richness (S_R) was calculated as the number of species recorded in each grid cell. We used a dated ...
