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。本研究构建了一套综合性数据集，收录了美洲地区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（occurrence records）。此次大规模数据汇编全面呈现了仙人掌类植物的空间分布格局，同时揭示了采样工作中存在的地理偏倚与分类学偏倚。本数据集可为生态学与生物地理学领域的研究推进提供宝贵资源，并支撑未来旨在阐明该标志性植物类群的多样性特征、分布现状与保护需求的相关分析。本数据库是对Amaral等人2022年编制的数据集的扩展完善。
