Amphibian database

Amphibian is a diverse terrestrial vertebrate group with more than 8000 species, which is an important part of major terrestrial and freshwater ecosystems. Unfortunately, amphibians are experiencing a worldwide population decline. Trait information is important for understanding the causes of endangerment. Meanwhile, such information is also essential for studying amphibians using trait-based approaches. However, such data of amphibians is the scarcest among terrestrial vertebrate groups. To fill this gap, we collected morphological traits of global amphibians available from the literature and compiled a database to facilitate future studies.
