Body mass records_DOetal.csv

Body mass is one of the most important phenotypic attributes in animal ecology and life history. This trait is widely used in the fields of ecology and macroevolution, since it influences physiology, morphological functions, as well as a myriad of ecological and social interactions. In this data set, our aim was to gather a comprehensive bird and mammal body mass data set from northern South America. We report body mass, discriminated by sex, for 42,022 individual birds and 7,441 mammals representing 1317 bird species (69% of Colombia’s avifauna) and 270 mammal species (51% of Colombian mammals) from the Neotropics. The data was sourced from vouchers collected between 1942 and 2020 and from individuals captured and released at banding stations over the last two decades for birds (2000 – 2020) and the last decade for mammals (2010 – 2020), by ten research groups and institutions in Colombia. This data set fills gaps identified in other similar databases, as it focuses on northern South America, a highly diverse Neotropical region often underrepresented in morphological data sets. We provide wide taxonomic coverage for studies interested in information both at regional and local scales.<br>

体重是动物生态学与生活史研究中极为关键的表型性状之一。该性状被广泛应用于生态学与宏观演化研究领域，因其可对生理机能、形态功能以及诸多生态与社会互动行为产生影响。
本数据集旨在汇集南美北部地区的鸟类与哺乳动物体重数据，构建全面的相关数据集。本次共记录了42022只鸟类与7441只哺乳动物的体重数据，且按性别进行区分；样本涵盖新热带区（Neotropics）的1317种鸟类（占哥伦比亚鸟类区系的69%）与270种哺乳动物（占哥伦比亚哺乳动物物种的51%）。
本数据集的数据来源于哥伦比亚十个研究团队与机构的采集工作：其中鸟类数据包含1942年至2020年采集的凭证标本，以及2000年至2020年近二十年间在鸟类环志站捕捉并放生的个体；哺乳动物数据则取自2010年至2020年近十年间的相关采样工作。
本数据集填补了其他同类数据库的现存空白，因其聚焦物种多样性极高的南美北部新热带区——该区域在现有形态学数据集中的代表性往往不足。
本数据集可为关注区域及局域尺度相关信息的研究提供广泛的分类学覆盖范围。
