Occurrences of cactaceae on the American continent

Reliable biodiversity data are fundamental for assessing species distributions, detecting knowledge gaps, and informing conservation strategies. We present a comprehensive dataset containing 435,694 georeferenced occurrence records for 1,892 species of Cactaceae across the Americas. This large-scale compilation provides an overview of the spatial distribution of cactus species, revealing geographic and taxonomic biases in sampling efforts. The dataset offers a valuable resource for advancing ecological and biogeographic research and supports future analyses aimed at understanding the diversity, distribution, and conservation needs of this emblematic plant family. This database is an expansion of the database compiled by Amaral et al., 2022

可靠的生物多样性数据是评估物种分布、识别研究空白、为保护策略制定提供科学依据的核心基础。本研究构建了一套覆盖美洲地区、包含1892种仙人掌科（Cactaceae）植物共计435694条带地理坐标的物种出现记录的综合数据集。该大规模整合数据集全面呈现了仙人掌物种的空间分布概况，同时揭示了采样工作中存在的地理与分类学偏差。本数据集可为生态与生物地理学研究的深化提供宝贵资源，并为后续针对该标志性植物类群的多样性、分布格局及其保护需求的相关分析提供有力支撑。本数据库是对Amaral等人2022年构建的数据库的扩充。
