abstract = {BackgroundWe aimed to characterise the geographical distribution of Sørensen-based multi-site dissimilarity (βsor) and its underlying true turnover (βsim) and nestedness (βsne) components for Chinese Lauraceae and to analyse their relationships to current climate and past climate change.MethodsWe used ensembles of small models (ESMs) to map the current distributions of 353 Lauraceae species in China and calculated βsor and its βsim and βsne components. We tested the relationship between βsor, βsne and βsim with current climate and past climate change related predictors using a series of simultaneous autoregressive (SARerr) models.ResultsSpatial distribution of βsor of Lauraceae is positively correlated with latitude, showing an inverse relationship to the latitudinal α-diversity (species richness) gradient. High βsor occurs at the boundaries of the warm temperate and subtropical zones and at the Qinghai-Tibet Plateau due to high βsne. The optimized SARerr model explains βsor and βsne well, but not βsim. Current mean annual temperature determines βsor and βsne of Lauraceae more than anomalies and velocities of temperature or precipitation since the Last Glacial Maximum.ConclusionsCurrent low temperatures and high climatic heterogeneity are the main factors explaining the high multi-site β-diversity of Lauraceae. In contrast to analyses of the β-diversity of entire species assemblages, studies of single plant families can provide complementary insights into the drivers of β-diversity of evolutionarily more narrowly defined entities.}
