Impact of an Updated Climate Database on Model Performance and Niche Variability in Species Distribution Modeling

Despite the continuous accrual of occurrence data, the climate datasets used in species distribution modeling (SDM), particularly in mechanistic frameworks such as CLIMEX, often remain based on outdated climate baselines. Here, we present an updated global climate database (1992-2021) and corresponding bioclimatic variables, specifically structured for CLIMEX compatibility while also supporting application across multiple SDM frameworks. By providing a temporally updated climate baseline and...
