Disturbance and habitat modification by humans can alter animal movement, leading to negative impacts on fitness, survival and population viability. However, the ubiquity and nature of these impacts across diverse taxa has not been quantified. We compiled 208 studies on 167 species from terrestrial and aquatic ecosystems across the globe to assess how human disturbance influences animal movement. We show that disturbance by humans has widespread impacts on the movements of birds, mammals, reptiles, amphibians, fish and arthropods. More than two-thirds of 719 cases represented a change in movement of 20% or more, with increases in movement averaging 70% and decreases −37%. Disturbance from human activities, such as recreation and hunting, had stronger impacts on animal movement than habitat modification, such as logging and agriculture. Our results point to a global restructuring of animal movement and emphasize the need to reduce the negative impacts of humans on animal movement.

人为干扰导致动物运动广泛中断

人类的干扰和栖息地改变会改变动物的运动,从而对健康、生存和种群生存能力产生负面影响。然而,这些影响在不同分类群中的普遍性和性质尚未量化。我们对来自全球陆地和水生生态系统的 167 个物种进行了 208 项研究,以评估人类干扰如何影响动物运动。我们表明,人类的干扰对鸟类、哺乳动物、爬行动物、两栖动物、鱼类和节肢动物的活动具有广泛影响。在 719 个案例中,超过三分之二的变化幅度为 20% 或更多,平均变化幅度为 70%,下降幅度为 -37%。人类活动(例如娱乐和狩猎)的干扰对动物运动的影响比栖息地改变(例如伐木和农业)的影响更大。
