Tundra Nunavik: Functional traits of bird and mammal species of Labrador and northern Quebec

While most ecological studies focus on the impact of climate change on some populations or species, broader, ecosystem-based information is needed to better predict the future state of the Arctic. We therefore conducted a large-scale study aimed at characterizing through modelling the vulnerability of tundra ecosystems to climate change. As part of this study, we gathered ecological and biological information on 183 mammal and bird species inhabiting Labrador and the province of Québec north of the 50°N. Distributions of mammals were taken from the International Union for the Conservation of Nature (IUCN), while distributions of birds were taken from BirdLife International and NatureServe. For each species, we compiled information on names (Latin, English, French, Inuktitut), diet, body mass, behaviour, lifespan, habitat and nest characteristics. This information originates from the scientific literature, large web databases, and expert advice. Information sources are listed in the dataset and a description of each species characteristic is available in the Supplementary documentation.

尽管大多数生态学研究集中于气候变化对某些种群或物种的影响，然而，为了更精确地预测北极未来的状态，我们需要更广泛的、基于生态系统的信息。鉴于此，我们开展了一项大规模研究，旨在通过建模来表征苔原生态系统对气候变化的脆弱性。作为本研究的组成部分，我们收集了栖息于拉布拉多地区以及50°N以北魁北克省的183种哺乳动物和鸟类物种的生态和生物信息。哺乳动物的分布数据来源于国际自然保护联盟（IUCN），而鸟类的分布数据则来源于国际鸟类生活保护组织（BirdLife International）和自然保护协会（NatureServe）。对于每一种物种，我们汇编了有关其学名（拉丁文、英文、法文、因纽特语）、饮食、体重、行为、寿命、栖息地以及巢穴特征的详细信息。这些信息源自科学文献、大型网络数据库以及专家意见。信息来源列于数据集中，每种物种特征的描述亦可在补充文档中找到。
