ReptTraits: a comprehensive database of ecological traits in reptiles

Trait databases have become important resources for large-scale comparative studies in ecology. Such an understanding has important implications for basic eco-evolutionary theory and conservation efforts worldwide. Reptiles are emerging as a key group for studying these questions, with new data accumulation accelerating. We collected data, from earlier databases and the primary literature, to create the most up-to-date database on reptilian traits with 40 traits from 12060 species of reptile (Amphisbaenia, Crocodylia, Rhynchocephalia, Sauria, Serpentes and Testudines). Data were collected from 1288 data sources published between 1820–2023. The data encompass various morphological, physiological, behavioural, and performance traits along with availability of genetic data, IUCN red list assessments, and population trends. Our goal was to provide this resource without restrictions, to keep the database current, and to grow the number of relevant traits in the future. Furthermore, as published data for some of the less well-known species are scarce, we hope this study can initiate a community effort to fill in data gaps.
