HomeRange: A global database of mammalian home ranges

Motivation: Home range is a common measure of animal space use as it provides ecological information that is useful for conservation applications. In macroecological studies, values are typically aggregated to species means to examine general patterns of animal space use. However, this ignores the environmental context in which the home range was estimated and does not account for intraspecific variation in home range size. In addition, the focus of macroecological studies on home ranges has been historically biased toward terrestrial mammals. The use of aggregated numbers and terrestrial focus limits our ability to examine home range patterns across different environments, variation in time and between different levels of organisation. Here we introduce HomeRange, a global database with 75,611 home-range values across 960 different mammal species, including terrestrial, as well as aquatic and aerial species.

研究背景与动机：家域（home range）是衡量动物空间利用的常用指标，其所承载的生态学信息可为物种保护实践提供关键支撑。在宏生态学（macroecology）研究中，现有研究通常将家域数值汇总为物种水平均值，以探究动物空间利用的一般模式。然而，该类做法忽略了家域估算时所处的环境背景，且未纳入家域面积的种内变异维度。此外，长期以来宏生态学研究对家域的关注存在偏向陆生哺乳动物的偏差。仅依赖汇总数据且研究对象局限于陆生类群的现状，制约了我们对不同环境、不同时间尺度以及不同组织层级下家域模式的探究能力。为此，本研究构建了HomeRange全球数据库，该库收录了960种哺乳动物的75611条家域估值数据，涵盖陆生、水生及空中活动的哺乳动物类群。
