Species interactions in the Anthropocene

Abstract

Research Highlight: Van Scoyoc, A., Smith, J. A., Gaynor, K. M., Barker, K., & Brashares, J. S. (2023) The influence of human activity on predator–prey spatiotemporal overlap. Journal of Animal Ecology, https://doi.org/10.1111/1365‐2656.13892. Few corners of the globe remain untouched by humans, and thus nearly all wildlife communities are influenced by human activity. Van Scoyoc et al. (2023) present a framework that places predator–prey interactions explicitly within an anthropogenic context, revealing that predator–prey dyads fall into one of four categories depending on whether predators and prey are attracted to or avoid human activity. These responses can either increase or decrease overlap among species via divergent pathways, which can help to make sense of seemingly conflicting patterns from prior studies. Their framework facilitates hypothesis testing, which they demonstrate with a meta‐analysis of 178 predator–prey dyads from 19 camera trap studies. With evidence for each of the four pathways, yet some unexpected outcomes for temporal overlap among dyads, this review generates exciting questions and lays out a productive path forward to improve our understanding of species interactions in the Anthropocene.
