Temporal shifts as elusive responses to anthropogenic stressors in a mammal community

Conservation decision-making often relies on species' distribution changes in response to anthropogenic disturbances but overlook their temporal responses. Filling the knowledge gap on the temporal shifts as elusive responses of wild animals to human activity is important because this may provide information for more proactive conservation planning. In this study, we used camera traps in a field survey technique to investigate the trade-offs between spatial and temporal responses of a mammal community to major human activities in Qinling Mountains, China. We focused on five most abundant mammalian species including giant panda (Ailuropoda melanoleuca), takin (Budorcas taxicolor), wild boar (Sus scrofa), tufted deer (Elaphodus cephalophus), and Chinese goral (Naemorhedus griseus), and examined the drivers of, and the trade-offs between the change of their spatial distributions and daily activity patterns in response to anthropogenic disturbances. We found that in response to human interferences, giant panda and takin mainly changed their distributions, while wild boar, tufted deer and Chinese goral altered their daily activity patterns, indicating the elusive responses of the latter species under anthropogenic stressors. In addition, anthropogenic stressors such as farming and tourism have more profound impacts on mammal communities than previously revealed by species distribution modeling only. For nature reserves that aim to conserve multiple species simultaneously, a more flexible, adaptive management framework is thus needed to capture the trade-offs between multiple species' spatial and temporal responses to anthropogenic disturbance.

Automated summary

The study investigated the spatial and temporal responses of mammal species to human activities in the Qinling Mountains, China, finding that giant pandas and takins mainly changed their distributions, while wild boars, tufted deer, and Chinese gorals altered their daily activity patterns in response to anthropogenic disturbances. This suggests that certain mammal species exhibit elusive responses to human interference, highlighting the need for a more adaptable conservation framework.
