A database of life-history,ecological,and biogeographical traits of snakes worldwide
The inherent ecological and life-history characteristics of organisms are fundamental in determining species population dynamics and survive strategies,as well as their ability to adapt to environmental changes.Snakes are a group of vertebrates with a high degree of morphological specialization.However,due to the cryptic nature of snakes and their solitary behavior,life-history and ecological studies on snakes remain relatively lagged compared with other vertebrate groups,and no comprehensive trait database specifically dedicated to snakes has been available.This study collected and compiled 28 traits of 4,145 snake species by systematically consulting published snake books,peer-reviewed and non-peer-reviewed literature,online databases and other data resources.These traits include life-history traits(8 traits including body mass,total length,prey),ecological traits(7 traits including distribution,microhabitat,elevational distribution),and biogeographical traits(13 traits including annual mean temperature,annual mean precipitation,normalized difference vegetation index(NDVI)).The data completeness of these traits ranged from 42.41％to 99.90％.Compared to other datasets,this dataset has the most complete number of species,the richest traits,and offers higher completeness for some traits.As the most comprehensive and up-to-date global trait dataset for snakes,it provides valuable data support for research in ecology,biogeography and conservation biology of snakes at both global and region scales.
