Trait hypervolumes based on natural history collections can detect ecological strategies that are distinct to biogeographic regions

<strong>specimen_localities_for_mapping_trait_hypervolumes.csv</strong> Point localities of specimens held in natural history collections for a random sample of 575 angiosperm species that all occur in the continent of Africa. Some of the localities were georeferenced as part of this research. Localities were spatially disaggregated using the R package <em>ecospat</em> prior to use in Species Distribution Models that were then used to spatially project biodiversity metrics. Fields: 1. Source How the specimen locality data was obtained: <strong>GBIF</strong> = from the Global Biodiversity Information Facility, <strong>TROPICOS </strong>= from Tropicos.org. Missouri Botanical Garden, <strong>Taxonomic_literature</strong> = specimens cited in published taxonomic literature, <strong>Kew_herbarium </strong>= specimens seen by authors in the herbarium of the Royal Botanic Gardens, Kew, London. <strong>RAINBIO =</strong> RAINBIO species checklist of tropical African vascular plants, <strong>LMA_herbarium</strong> = specimens seen by authors in the herbarium of the Agricultural Research Institute of Mozambique, Maputo, Mozambique, <strong>Kitwe_herbarium</strong> = specimens seen by authors in the herbarium of the Division of Forest Research Forestry Department, Kitwe, Zambia, <strong>Edinburgh_herbarium</strong> = specimens seen by authors in the herbarium of the Royal Botanic Garden Edinburgh, <strong>Windhoek_herbarium</strong> = specimens seen by authors in the herbarium of the National Herbarium of Namibia, <strong>UPS_herbarium </strong>= specimens seen by authors in the herbarium of the Museum of Evolution, Uppsala, Sweden. 2.

本数据集收录了馆藏于自然历史博物馆的、随机抽取的575个非洲分布被子植物（angiosperm）物种的标本采样点坐标。部分采样点的地理坐标是在本研究中完成地理配准的。在用于构建物种分布模型（Species Distribution Models）之前，我们使用R语言包<em>ecospat</em>对采样点进行了空间解聚，随后利用该模型对生物多样性指标进行空间投影。
