Abstract
Integrated datasets linking traits, spatial distributions, environmental variables andphylogenies are essential for comparative research, but remain limited for many planttaxa, including those which are most threatened. Cactaceae are a morphologically and ecologically diverse succulent family that are iconic components of ecosystems across the Americas, and face high extinction risk. To support future comparative research, we present CactEcoDB (The Cactus Ecological Database), an Open Access dataset of curated spatial, ecological, trait, phylogenetic, and diversification data for over 1,000 cactus species. CactEcoDB includes species-level trait data, geographic occurrence records, environmental variables, range size estimates, speciation rates, and the largest time-calibrated phylogeny of cacti to date. By integrating these diverse data in a single and accessible platform, CactEcoDB is intended as a community resource for ecological, evolutionary, biogeographic, and conservation-focussed studies involving cacti, one of the most celebrated yet threatened plant families.
