Life history and maximum weight database for rays (Class Chondrichthyes, Superorder Batoidea) up to June 2022

Database of available life history data for ray species (Class Chondrichthyes, Superorder Batoidea) including study location, maximum size, length at maturity, age at maturity, maximum age, growth k, litter size, gestation and breeding interval. Literature search up to June 2022 with references included (authors, date, and DOI). Prepared for use in estimating species-specific maximum intrinsic rate of population increase (rmax) in the paper: 'Tropical rays are intrinsically more sensitive to overfishing than the temperate skates'. https://doi.org/10.1016/j.biocon.2023.110003. Maximum weight data with references for 85 rays used in analyses for this manuscript also provided.
Additional offspring length (disc width or total length) data sourced from Last et al., 2016 Rays of the World, Sharkipedia, and IUCN Red List Assessments as of December 2023 along with length-weight conversions sourced from FishBase for use in the manuscript entitled: 'Offspring size resolves a latitudinal population growth rate paradox in rays and skates'.

本数据集收录鳐总目（Superorder Batoidea，隶属软骨鱼纲Class Chondrichthyes）各物种的公开生命史数据，涵盖研究位点、最大体型、性成熟体长、性成熟年龄、最大年龄、生长参数k、胎仔数、妊娠期及繁殖间隔等核心指标。文献检索范围截至2022年6月，且完整收录相关参考文献信息，包括作者、发表年份及数字对象标识符（DOI）。本数据集专为估算物种种群最大内禀增长率（rmax）而构建，相关研究成果发表于论文《热带鳐类比温带魟类对过度捕捞的内在敏感性更高》（https://doi.org/10.1016/j.biocon.2023.110003）。此外，本手稿分析所用的85种鳐类的最大体重数据及对应参考文献亦一并纳入数据集。
额外收录的幼体体长（盘宽或总长度）数据，采集自截至2023年12月的Last等人2016年专著《世界鳐类》、Sharkipedia及国际自然保护联盟红色名录评估（IUCN Red List Assessments）；同时辅以从FishBase获取的体长-体重转换参数，以供题为《幼体体型破解鳐类与魟类种群增长率的纬度悖论》的手稿研究使用。
