Journal of Animal Ecology, Volume 93, Issue 9, Page 1176-1191, September 2024.During fall migration, avivorous raptors and avian prey co‐occur across space and time. We used a novel approach—combining eDNA metabarcoding and eBird data—to investigate predator–prey interactions between an avivorous raptor and co‐occurring avian prey species. This approach revealed prey availability and traits influence raptor‐songbird interactions

The specialised buzz pollination syndrome poses a partial barrier to plant invasions
Journal of Ecology, Volume 112, Issue 8, Page 1686-1700, August 2024.We found that plants that exhibit traits consistent with the buzz‐pollination syndrome are underrepresented as invasive species across the globe. Our result suggests that the specialist buzz‐pollination syndrome poses a partial barrier to plant invasions. Our review also highlighted six alternative insect behaviours that can enable invasive plants with
