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 0 ºC isotherm in the Last Glacial Maximum as a tipping point, we tested the following hypotheses: northern European assemblages host fewer 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 correlates positively with human influence, while phylogenetic and trait diversity show clustered patterns in areas with stronger human influence.

当前的气候，以及长期的气候变化和人类影响，决定了欧洲哺乳动物多样性的地理分布

已知历史气候变化，当前气候和人类影响会影响当前物种的丰富度，但很少研究它们对系统发育和性状多样性的影响。我们研究了这三个因素与欧洲哺乳动物物种独立变异，系统发育和性状多样性的关系。考虑到0°C等温线在上一次冰河极大期的位置作为转折点，我们检验了以下假设：北欧组合的寄主数量少于南部组合；北部地区具有特征和系统发育上的聚类组合，而更稳定的南部地区则具有随机或过度分散的组合。物种丰富度与人类影响呈正相关，
