ReptTraits: a comprehensive dataset of ecological traits in reptiles

Trait datasets are increasingly being used in studies investigating the eco-evolutionary theory and global conservation initiatives. 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 dataset 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 intention is to make this resource freely accessible, ensuring its current status and encouraging the inclusion of additional relevant traits in the future. Gaps in trait data might impede our ability to conduct large-scale analyses but we aim to catalyse a collaborative effort within the scientific community to address these data gaps.
