CarniDIET 1.0: A database of terrestrial, carnivorous mammal diets

Motivation: A species’ diet is central to understanding many aspects of its biology, including its behaviour, movement, and ecological niche. The diets of terrestrial carnivorous mammals, defined here as species primarily consuming other mammals (hereafter, mammal-consumers), have been extensively studied and can vary in the proportion of different food types, and species, consumed across their geographic ranges. Accessibility to data capturing such variation in diets of mammal-consumers across the variety of ecosystems they occur in would provide valuable information for conservation, and open research avenues for macroevolution and macroecology. However, data on mammal-consumer diets across their geographic ranges have not been systematically collated. Here, we present CarniDIET (Version 1.0), an open-access database containing quantitative data on the diets of terrestrial mammal-consumers collated from the literature.

研究背景：物种的食性是理解其生物学诸多维度的核心，包括其行为、活动模式与生态位。本文所定义的陆生食肉哺乳动物，即以其他哺乳动物为主要食物来源的类群（下称哺乳类食性动物），其食性已被广泛研究，且不同食物类型与猎物物种的摄入比例在其地理分布范围内存在差异。获取能够反映哺乳类食性动物在所栖息各类生态系统中食性差异的数据，将为物种保护提供宝贵参考，并为宏观进化与宏观生态学研究开辟新的方向。然而，目前尚未有研究对哺乳类食性动物在其地理分布范围内的食性数据进行系统性整理。为此，我们发布CarniDIET（版本1.0），这是一个开源数据库，收录了从文献中整理得到的陆生哺乳类食性动物食性的定量数据。
