Relative influence of environmental variables on explained variance of patterns of terrestrial vertebrate species richness at the pan-European scale and by ecoregions modelled using Boosted Regression Trees.

<p>“Arc”: Arctic; “AlpN”: Northern Alpine; “Bor”: Boreal; “AtlN”: Northern Atlantic; “Cont”: Continental; “Nem”: Nemoral; “AtlC”: Central Atlantic; “Step”: Steppic; “AlpS”: Southern Alpine; “Pan”: Pannonian; “Lus”: Lusitanian; “MedM”: Mediterranean Mountains; “MedN”: Northern Mediterranean; “MedS”: Southern Mediterranean; “Ana”: Anatolian. Environmental variables are detailed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0131924#pone.0131924.t001" target="_blank">Table 1</a>. Values in brackets are the performance of BRT model for each taxon and expressed as a percent of deviance explained (%).
