    　View Summary

    Incomplete sampling of species' geographic distributions has challenged biogeographers for many years to precisely quantify global-scale biodiversity patterns. After correcting for the spatial inequality of sample completeness, we generated a global species diversity map for woody angiosperms (82,974 species, 13,959,780 occurrence records). The standardized diversity estimated more pronounced latitudinal and longitudinal diversity gradients than the raw data and improved the spatial prediction of diversity based on environmental factors. We identified areas with potentially high species richness and rarity that are poorly explored, unprotected, and threatened by increasing human pressure: They are distributed mostly at low latitudes across central South America, Central Africa, subtropical China, and Indomalayan islands. These priority areas for botanical exploration can help to efficiently fill spatial knowledge gaps for better describing the status of biodiversity and improve the effectiveness of the protected area network for global woody plant conservation.

  • Global patterns of phylogenetic beta‐diversity components in angiosperms

    Abstract Questions Geographic gradients of beta‐diversity help understanding the relationship between species and their environment. However, on a global scale, such patterns are only known for a few taxa, mainly terrestrial vertebrates, especially when considering the phylogenetic dimension. Here, we present the first global analysis of phylogenetic beta‐diversity (PBD) for angiosperms. We aim to disentangle the relative contribution of PBD components (turnover‐ and nestedness‐resultant differences) and the deviation of PBD given the taxonomic beta‐diversity (TBD) along environmental and geographic gradients. Location Global. Methods We compiled range maps of 207,146 angiosperm species at 1° cells and calculated PBD for assemblages formed by each focal cell and its neighboring cells in radii of 1.5° and 2° (“moving‐window" approach). PBD was decomposed into turnover‐ and nestedness‐resultant components, evaluating their relative importance as the proportion of nestedness‐resultant PBD to the total PBD (PBD<sub>ratio</sub>). To evaluate lineage exchanges, we calculated the deviation of PBD from TBD (PBD<sub>dev</sub>). We assessed the breakpoints of relationship between PBD and geographic (latitude and elevation) and environmental (temperature and precipitation) gradients using linear piecewise regressions. Results The turnover‐resultant component was predominant in shaping the global angiosperm PBD pattern. PBD<sub>ratio</sub> was positively correlated with temperature, having a breakpoint around 14°. Because PBD<sub>dev</sub> was mostly positive, TBD prevailed over PBD; PBDdev was correlated significantly with latitude and temperature gradients, being higher (i.e., low lineage replacement compared with species replacement) at latitudes above 50° N, and in colder climates (below 2°C). Conclusions We provided the first global assessment of current geographic PBD patterns for angiosperms. Our results showed that such patterns are largely dictated by global environmental and geographic gradients, with lineage replacement being more important than lineage loss in virtually all areas, except at higher latitudes and on islands and peninsulas.

    Yasuhiro Kubota receives the Award for the paper Kubota, Y., Kusumoto, B., Shiono, T., & Ulrich, W. (2018). Environmental filters shaping angiosperm tree assembly along climatic and geographic gradients. Journal of Vegetation Science, 29, 607–618. This study is an excellent example of using fine-scale plant community data from forest vegetation plots sampled on different continents to address macroecological questions about the evolution of the global phylogenetic diversity of angiosperm floras. Using a global dataset of forest plots, Kubota et al. convincingly demonstrated that phylogenetic clustering of angiosperm trees is stronger in those regions of the world that are currently drier and experienced a larger climatic change during the Quaternary. This study significantly contributes to our understanding of global diversity patterns, including the differences between tropical and extratropical diversity.
