Physiology can underlie movement, including short-term activity, exploration of unfamiliar environments, and larger scale dispersal, and thereby influence species distributions in an environmentally sensitive manner. We conducted meta-analyses of the literature to establish, firstly, whether physiological traits underlie activity, exploration, and dispersal by individuals (88 studies), and secondly whether physiological characteristics differed between range core and edges of distributions (43 studies). We show that locomotor performance and metabolism influenced individual movement with varying levels of confidence. Range edges differed from cores in traits that may be associated with dispersal success, including metabolism, locomotor performance, corticosterone levels, and immunity, and differences increased with increasing time since separation. Physiological effects were particularly pronounced in birds and amphibians, but taxon-specific differences may reflect biased sampling in the literature, which also focussed primarily on North America, Europe, and Australia. Hence, physiology can influence movement, but undersampling and bias currently limits general conclusions.
生理学可以作为运动的基础，包括短期活动、探索陌生环境和更大规模的扩散，从而以对环境敏感的方式影响物种分布。我们对文献进行了荟萃分析，首先确定个体的生理特征是否是活动、探索和扩散的基础（88 项研究），其次确定分布范围的核心和边缘之间的生理特征是否存在差异（43 项研究）。我们表明，运动表现和新陈代谢以不同程度的置信度影响个体的运动。与核心区域相比，分布范围的边缘区域在可能与扩散成功相关的特征上存在差异，包括新陈代谢、运动表现、皮质酮水平和免疫力，而且随着时间的推移，差异会越来越大。生理效应在鸟类和两栖动物中尤为明显，但分类群的差异可能反映了文献中的有偏采样，这些文献主要集中在北美、欧洲和澳大利亚。因此，生理学可以影响运动，但采样不足和偏差目前限制了普遍结论。
