MOMv3.3.txt Description The purpose of this data set was to compile body mass information for all mammals on Earth so that we could investigate the patterns of body mass seen across geographic and taxonomic space and evolutionary time. We were interested in the heritability of body size across taxonomic groups (How conserved is body mass within a genus, family, and order?), in the overall pattern of body mass across continents (Do the moments and other descriptive statistics remain the same across geographic space?), and over evolutionary time (How quickly did body mass patterns iterate on the patterns seen today? Were the Pleistocene extinctions size specific on each continent, and did these events coincide with the arrival of man?). These data are also part of a larger project that seeks to integrate body mass patterns across very diverse taxa (NCEAS Working Group on Body size in ecology and paleoecology: linking pattern and process across space, time and taxonomic scales). We began with the updated version of Wilson and Reeder’s (1993) taxonomic list of all known Recent mammals of the world (<i>N</i> = 4629 species) to which we added status, distribution, and body mass estimates compiled from the primary and secondary literature. Whenever possible, we used an average of male and female body mass, which was in turn averaged over multiple localities to arrive at our species body mass values. The sources are line referenced in the main data set, with the actual references appearing in a table within the metadata. Mammals have individual records for each continent they occur on. Please note that our data set is more than an amalgamation of smaller compilations. Although we relied heavily a data set for Chiroptera by K. E. Jones (<i>N</i> = 905), the CRC handbook of Mammalian Body Mass (<i>N</i> = 688), and a data set compiled for South America by P. Marquet (<i>N</i> = 505), these total less than half the records in the current database. The remainder are derived from more than 150 other sources (see reference table). Furthermore, we include a comprehensive late Pleistocene species assemblage for Africa, North and South America, and Australia (an additional 230 species). “Late Pleistocene” is defined as approximately 11 ka for Africa, North and South America, and as 50 ka for Australia, because these times predate anthropogenic impacts on mammalian fauna. Estimates contained within this data set represent a generalized species value, averaged across gender and geographic space. Consequently, these data are not appropriate for asking population-level questions where the integration of body mass with specific environmental conditions is important. All extant orders of mammals are included, as well as several archaic groups (<i>N</i> = 4859 species). Because some species are found on more than one continent (particularly Chiroptera), there are 5731 entries. We have body masses for the following: Artiodactyla (280 records), Bibymalagasia (2 records), Carnivora (393 records), Cetacea (75 records), Chiroptera (1071 records), Dasyuromorphia (67 records), Dermoptera (3 records), Didelphimorphia (68 records), Diprotodontia (127 records), Hydracoidea (5 records), Insectivora (234 records), Lagomorpha (53 records), Litopterna (2 records), Macroscelidea (14 records), Microbiotheria (1 record), Monotremata (7 records), Notoryctemorphia (1 record), Notoungulata (5 records), Paucituberculata (5 records), Peramelemorphia (24 records), Perissodactyla (47 records), Pholidota (8 records), Primates (276 records), Proboscidea (14 records), Rodentia (1425 records), Scandentia (15 records), Sirenia (6 records), Tubulidentata (1 record), and Xenarthra (75 records). <i>Key words</i>: <i>body mass; extinct mammals; late Quaternary; macroecology; taxonomy.</i>文件列表 数据文件采用ASCII格式，以制表符分隔，未使用任何压缩方案。本数据集不含表头行，共包含5732条记录。 MOMv3.3.txt 数据集说明 本数据集旨在收录全球所有哺乳动物的体质量（body mass）数据，以探究地理、分类学维度以及演化时间尺度下的体质量分布模式。我们的研究兴趣涵盖：不同分类群内体尺寸的遗传保守性（即属、科、目级阶元内的体质量保守程度如何？）；各大洲间体质量的整体分布模式（即各大陆的体质量矩统计量及其他描述性统计量是否保持一致？）；以及体质量随演化时间的变化规律（即现代体质量模式的演化速率如何？更新世（Pleistocene）集群灭绝在各大陆是否存在体型选择性？这些灭绝事件是否与人类抵达各大陆的时间相吻合？）。 本数据集同时隶属于一项旨在整合多样类群体质量分布模式的大型研究项目——美国国家生态分析与合成中心（National Center for Ecological Analysis and Synthesis，简称NCEAS）“生态学与古生态学中的体尺寸：跨空间、时间与分类学尺度关联模式与过程”工作组。 我们以Wilson与Reeder于1993年发表的全球现生哺乳动物分类名录更新版（共收录4629个物种）为基础，补充了物种的保护现状、分布范围以及从一手、二手文献中整理得到的体质量估算值。在条件允许的情况下，我们先计算雌雄个体体质量的平均值，再对多个采样地点的该平均值再次取平均，以此得到各物种的体质量数值。数据集中的文献来源已进行行内标注，完整参考文献列表见元数据中的附表。 哺乳动物的每条记录对应其分布的单个大洲。需说明的是，本数据集并非仅由小型数据集汇编而成：尽管我们大量参考了K. E. Jones编撰的翼手目（Chiroptera）数据集（共905条记录）、《哺乳动物体质量CRC手册》（共688条记录）以及P. Marquet编撰的南美哺乳动物数据集（共505条记录），但这三项来源的总记录数尚不足当前数据库总记录数的一半。剩余记录均来自150余个其他数据源（详见参考文献附表）。此外，我们还补充了非洲、北美、南美及澳大利亚的晚更新世物种组合（额外新增230个物种）。“晚更新世”的时间界定为：非洲、北美、南美约11千年前，澳大利亚约50千年前，该时间节点早于人类活动对哺乳动物区系造成显著影响的时期。 本数据集收录的体质量估算值为物种水平的通用数值，已按性别与地理范围进行平均。因此，本数据集不适用于需要结合特定环境条件分析体质量与种群关联的研究问题。 本数据集涵盖所有现生哺乳动物目，以及部分已灭绝的古老类群，共收录4859个物种。由于部分物种（尤其是翼手目）分布于多个大洲，因此实际总条目数为5731条，而不含表头行的原始总记录数为5732条。我们已收录以下类群的体质量数据：偶蹄目（Artiodactyla，280条记录）、Bibymalagasia（2条记录）、食肉目（Carnivora，393条记录）、鲸目（Cetacea，75条记录）、翼手目（Chiroptera，1071条记录）、袋鼬目（Dasyuromorphia，67条记录）、皮翼目（Dermoptera，3条记录）、负鼠目（Didelphimorphia，68条记录）、双门齿目（Diprotodontia，127条记录）、蹄兔目（Hydracoidea，5条记录）、食虫目（Insectivora，234条记录）、兔形目（Lagomorpha，53条记录）、滑距骨目（Litopterna，2条记录）、象鼩目（Macroscelidea，14条记录）、微兽目（Microbiotheria，1条记录）、单孔目（Monotremata，7条记录）、Notoryctemorphia（1条记录）、箭齿兽目（Notoungulata，5条记录）、鼩负鼠目（Paucituberculata，5条记录）、袋狸目（Peramelemorphia，24条记录）、奇蹄目（Perissodactyla，47条记录）、鳞甲目（Pholidota，8条记录）、灵长目（Primates，276条记录）、长鼻目（Proboscidea，14条记录）、啮齿目（Rodentia，1425条记录）、树鼩目（Scandentia，15条记录）、海牛目（Sirenia，6条记录）、管齿目（Tubulidentata，1条记录）以及异关节总目（Xenarthra，75条记录）。 关键词：体质量；已灭绝哺乳动物；晚第四纪；宏生态学；分类学。
