Intraguild predation in sympatric seals and the effect on a declining population. [PDF]
J Anim EcolThis study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.

Global Change Asymmetrically Rewires Ecosystems. [PDF]
Ecol LettUnderstanding how global environmental change affects food webs remains a key challenge. We synthesise empirical studies to reveal a general pattern of asymmetric rewiring, where anthropogenic pressures differentially impact habitats and restructure energy pathways within food webs.
