Authors: Gemma Carroll, Briana Abrahms, Stephanie Brodie & Megan A. Cimino Journal: Nature Ecology and Evolution DOI: https://doi.org/10.1038/s41559-024-02454-0 “Climate change is driving a rapid redistribution of life on Earth. Variability in the rates, magnitudes and directions of species’ shifts can alter spatial overlap between predators and prey, with the potential to decouple trophic interactions. Although phenological mismatches between predator requirements

BrasharesJournal: Movement EcologyDOI: https://doi.org/10.1186/s40462-024-00471-z Abstract Excerpt: “Our study indicates that hunters can successfully employ a diversity of harvest strategies, and that hunting success is mediated by the interacting effects of hunting mode and landscape features. Such results highlight the breadth of human hunting modes, even
