Editor’s summary
Agriculture, settlements, roads, and other infrastructure profoundly shape the habitats that are available to nonhuman animals. In addition to changing their behavior to avoid or exploit these new hazards and resources, many species may also directly avoid humans. Oliver et al. examined how bird and mammal habitat use depends on both human land use and direct human presence using mobile device data to determine where people are (see the Perspective by Beaudrot). Across 37 species with geolocation data in the United States, most species responded directly to human movements, with most of these showing interactive effects between human land use and human presence. Considering only human effects on land cover will thus often provide inaccurate assessments of species’ habitat use. —Bianca Lopez
Abstract
Sustainable human–wildlife coexistence requires a mechanistic understanding of the many ways that humans affect animals. However, progress is hampered by the lack of accessible data measuring the dynamic presence of people. Here, we leverage mobile-device data to disentangle how human presence and landscape modification differentially influence the use of geographic and environmental space for 37 mammal and bird species across the United States. Human presence affected more than 65% of species, with substantial variation across species. For ~60% of species that responded to human activities, the effects were interdependent—animals tended to react more strongly to human presence in less modified habitats. Our results demonstrate that human presence and landscape modification have complex combined effects on wildlife, which need to be considered for effective management.
