A dataset on the morphological, life-history and ecological traits of mammals in China

Species traits reflect the species’ ecological function and fitness. The trait databases play a vital role in studying biodiversity maintenance and loss, species evolution and adaptation, ecological interactions and processes, ecosystem functions, and species responses to both climate change and human pressures. China is one of the countries with the richest mammal diversity in the world, so far, there is no comprehensive resource of morphological, life history, ecological and geographical distribution data of the mammals in China. We compiled 24 traits data of 754 Chinese mammals (including recently regional extinct species and those species with disputed taxonomy and distribution) between 2008 and 2021 through systematic literature review and dataset integration, referred to mammalian monographs and field guides. The main sources used in completing the dataset were: the life history traits were retrieved from trait database (COMBINE: COalesced Mammal dataBase of INtrinsic and Extrinsic traits, Soria et al, 2021); Smith and Xie (2009) A Guide to the Mammals of China and Pan et al (2007) A Field Guide to the Mammals of China, and the zoogeographical regionalization and distribution type were searched in Zhang (2011) China Animal Geography, and species distribution in provinces and threatened category were cited from Jiang et al (2021) China’s Red list of Biodiversity: Vertebrates, Volume I, Mammals and Liu et al (2019; 2020) Handbook of Mammals of China. In addition, Handbook of the Mammals of the World (Wilson & Mittermeier, 2009; 2011; 2012; 2018; 2019; Mittermeier & Wilson, 2014; Wilson et al, 2016), Mammal Diversity Database (American Society of Mammalogists, ASM, 2021) and COMBINE (COalesced Mammal dataBase of INtrinsic and Extrinsic traits, Soria et al, 2021) were taken as supplementary data source. Further, peer–reviewed scientific publications from 1990 to 2021 were searched in CNKI, Google Scholar to supplementary traits data. Our dataset included body weight, brain size, head body length, tail length, forearm length (Chiroptera), hind foot length, ear length, sexual maturity time, gestation length, litter size, litters per year, generation length, diet, activity pattern, habitat type, habitat breadth, realm, biome, endemic species, elevational range, distribution type, zoogeographical regionalization, geographical distribution. Among these twenty-four traits, the data integrity ranged from 30.11% to 100.00%. The traits data were incomplete to some extent due to lack of research while the information about endemic species, geographical distribution in province of China’s mammals are completed. The dataset is the latest and most complete database on the traits of China’s mammals, which lays the foundation for future researches in mammalogy and biodiversity study and promote information sharing and in-depth mining of mammal diversity in China.

物种性状反映了物种的生态功能与适合度。性状数据库在生物多样性维持与丧失、物种演化与适应、生态相互作用与过程、生态系统功能，以及物种对气候变化与人为压力的响应等研究中发挥着至关重要的作用。中国是全球哺乳动物多样性最为丰富的国家之一，但迄今为止尚未有涵盖中国哺乳动物形态、生活史、生态及地理分布数据的综合性资源库。本数据集通过系统文献调研与数据集整合，参考哺乳动物专著及野外指南，于2008年至2021年间收集了754种中国哺乳动物（包含近期区域灭绝物种及分类学与分布存在争议的物种）的24项性状数据。本数据集的主要数据来源如下：生活史性状提取自性状数据库COMBINE（COalesced Mammal dataBase of INtrinsic and Extrinsic traits，Soria等，2021）；《中国哺乳动物图鉴》（Smith & Xie，2009）与《中国哺乳动物野外指南》（Pan等，2007）；动物地理区划与分布型的数据源自《中国动物地理》（张荣祖，2011）；省级物种分布数据与受威胁等级引用自《中国生物多样性红色名录：脊椎动物 第一卷 哺乳动物》（Jiang等，2021）以及《中国哺乳动物志》（Liu等，2019；2020）。此外，本数据集还将《世界哺乳动物手册》（Wilson & Mittermeier，2009；2011；2012；2018；2019；Mittermeier & Wilson，2014；Wilson等，2016）、哺乳动物多样性数据库（美国哺乳动物学会[American Society of Mammalogists, ASM]，2021）以及前述COMBINE数据库作为补充数据源。同时，本研究还于CNKI与Google Scholar中检索了1990年至2021年间的同行评议科学文献，以补充性状数据。本数据集涵盖的24项性状包括：体重、脑容量、头体长、尾长、前臂长（翼手目适用）、后足长、耳长、性成熟时间、妊娠期、胎仔数、年产胎数、世代长度、食性、活动节律、生境类型、生境宽度、生物地理区、生物群区、特有物种、海拔范围、分布型、动物地理区划以及地理分布。在上述24项性状中，数据完整度介于30.11%至100.00%之间。由于部分类群研究不足，部分性状数据存在一定程度的缺失，但中国哺乳动物的特有物种信息与省级地理分布数据均已完整收录。本数据集是当前最新且最为全面的中国哺乳动物性状数据库，可为未来哺乳动物学与生物多样性相关研究奠定基础，并推动中国哺乳动物多样性的信息共享与深度挖掘。
