SquamBase 1.0 – a dataset of squamate species traits

Motivation: I present a database that contains information on multiple key traits for all 11,744 recognized species of squamates worldwide. The database encompasses key traits and hopefully a reasonably comprehensive picture of available public knowledge. I present a comprehensive description of the sources and rationale leading to the assignment of each particular trait state for each species. Hopefully, the dataset can serve the scientific community and promote research and understanding of the group, comparisons with other taxa, and assessment of conservation needs. Furthermore, gaps in our knowledge of squamate traits become readily apparent and will hopefully lead to further study and even better knowledge.

Main types of variables contained: morphological, ecological, life history, geographic and conservation-related traits

Spatial location: Global

Time period: Late Holocene to recent

Major taxa and level of measurement: Squamata, species

Software format: .xlsx

Methods
Data were manually collected over 18 years.

研究背景：本文构建一套数据库，收录全球11744个已确认的有鳞目（Squamata）物种的多项关键性状信息。该数据库涵盖核心性状数据，力求全面整合现有公开可获取的相关研究成果。本文详细阐述了为各物种赋予特定性状状态的依据与数据来源逻辑。本数据集旨在服务科研共同体，推动该类群的研究与认知深化，助力与其他类群的比较分析，以及物种保护需求评估。此外，当前我们对有鳞目性状认知的空白将清晰显现，有望推动后续相关研究，进一步完善相关知识体系。
