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.

本数据集收录了自然历史馆藏标本的采样点坐标，涵盖随机选取的、均分布于非洲大陆的575种被子植物（angiosperm）。部分采集点的地理坐标是在本研究中完成地理配准的。在将采集点输入物种分布模型（Species Distribution Model）之前，研究人员已通过R语言包*ecospat*对采集点进行空间拆分，后续该模型被用于空间推演生物多样性指标。
