A vision for incorporating human mobility in the study of human-wildlife interactions

Wildlife are affected by human movement and static human infrastructure. In this Perspective, the authors propose a 'dynamic human footprint' that incorporates metrics accounting for time-varying human activities. As human activities increasingly shape land- and seascapes, understanding human-wildlife interactions is imperative for preserving biodiversity. Habitats are impacted not only by static modifications, such as roads, buildings and other infrastructure, but also by the dynamic movement of people and their vehicles occurring over shorter time scales. Although there is increasing realization that both components of human activity substantially affect wildlife, capturing more dynamic processes in ecological studies has proved challenging. Here we propose a conceptual framework for developing a 'dynamic human footprint' that explicitly incorporates human mobility, providing a key link between anthropogenic stressors and ecological impacts across spatiotemporal scales. Specifically, the dynamic human footprint integrates a range of metrics to fully acknowledge the time-varying nature of human activities and to enable scale-appropriate assessments of their impacts on wildlife behaviour, demography and distributions. We review existing terrestrial and marine human-mobility data products and provide a roadmap for how these could be integrated and extended to enable more comprehensive analyses of human impacts on biodiversity in the Anthropocene.

Automated summary

Wildlife are affected by human movement and static human infrastructure. The authors propose a 'dynamic human footprint' that incorporates metrics accounting for time-varying human activities. Understanding human-wildlife interactions is crucial for preserving biodiversity as human activities shape landscapes, and capturing more dynamic processes in ecological studies is challenging.
