中国两栖类生活史和生态学特征数据集

A dataset on the life-history and ecological traits of Chinese amphibians

截至2021年底,中国共记载591种两栖类(不包括外来入侵种),是世界上两栖类物种数最多的国家之一。物种特征影响和决定了物种在环境中的生存能力,在进化生物学、生态学和保护生物学研究中具有重要作用。目前,中国两栖类在线数据库(https://www.amphibiachina.org)已经整理了我国两栖类的形态特征、生物学信息和地理分布等部分物种特征,但仍缺乏一个完整的、可自由检索的数据集。通过系统查阅文献和数据检索,本文收集整理了中国全部591种本土两栖类的22个特征数据,包括物种发现时间(最早发现和描述新物种文章的发表时间)、模式产地、中国受威胁等级、全球受威胁等级、致危因子、是否中国特有种、是否岛屿特有种、雄性体长、雌性体长、窝卵数、卵径、产卵地点、幼体主要生境、成体微生境、活动模式、生殖周期、繁殖时间、是否有亲本照顾、受精方式、海拔范围、分布地区、分布省份数。除了物种发现时间、是否岛屿特有种、分布地区、分布省份数外,其余特征数据都有不同程度的缺失,数据完整度为27.92%-100%,平均完整度为71.72%,标准差为24%。本数据集是目前我国两栖类最新和最全的物种特征数据库,希望可以为我国两栖类生态学、保护生物学、生物地理学等研究提供数据支持。

China has a total of 591 amphibian species(not including alien invasive species)as of the end of 2021 and is one of the countries with the richest amphibian diversity in the world.The species traits of amphibians affect their survival in the environment and play an important role in the study of evolutionary biology,ecology,and conservation biology.AmphibiaChina(https://www.amphibiachina.org)has compiled some data on the life-history traits,ecological traits,and geographical distribution of Chinese amphibians.However,we still lack an accessible database of the species traits of Chinese amphibians.Through extensive retrieval and searching,we systematically collected data on 22 characteristic traits related to the life-history,ecology,and geographic distribution of all the 591 amphibian species in China.The 22 characteristic traits included:the discovered time of species,holotype location,China Red List status,IUCN Red List status,threatened factors,Chinese endemism,insular endemism,body size of male/female,clutch size,egg size,breeding site,primary larval habitat,adult microhabitat,activity cycle,reproductive cycle,breeding time,parental care,fertilization type,elevational range,domestic distribution,and the number of provinces distributed.Except for the discovered time of species,domestic distribution,the number of provinces distributed,and insular endemism,the data on other traits were incomplete to varying degrees.The data completeness varied from 27.92%to 100%,with the mean completeness of 71.72%and a standard deviation of 24%.This dataset is the latest and most complete one of species traits of all the amphibian species native to China.This dataset can provide data support for the research of the ecology,conservation biology,and biogeography of Chinese amphibians.
