Data from: Current climate, isolation and history drive global patterns of tree phylogenetic endemism

摘要: Aim: We mapped global patterns of tree phylogenetic endemism (PE) to identify hotspots and test hypotheses about possible drivers. Specifically, we tested related current climate, geographical characteristics historical conditions, assessed their relative importance in shaping PE patterns. Location: Global. Time period: used the present distribution trees, predictors covering conditions from mid-Miocene present. Major taxa studied: All seed-bearing trees. Methods: compiled distributions for 58,542 species across 463 regions worldwide, matched these a recent phylogeny seed plants, calculated each region. suite predictor variables describing climate (e.g. mean annual temperature), isolation) cover at last glacial maximum) spatial regression model explain variation PE. Results: Tree was highest on islands, higher closer equator. three groups contributed substantially pattern. Isolation topographic heterogeneity promoted high PE, as did cover. Among mainland regions, temperature seasonality strongly negatively while positively islands. Some relationships differed among major floristic regions. For example, maximum positive Paleotropics, Miocene negative Neotropics. Main conclusions: Globally, can be explained by combination geographic, historical, factors. geographic appear key However, impact historic differs considerably reflecting unique histories. Hence, trees is result globally relevant drivers regional climatic
