Wildlife Biology, EarlyView.Food acquisition is arguably the most important, and among the riskiest behaviours for most mammals. Carcasses are an ephemeral resource for many scavengers, particularly black‐backed jackals Lupulella mesomelas that prey on small mammals. Landscape of fear theory suggests that prey species should reduce their activity in areas of high predator ...

Animal Conservation, EarlyView.Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis
British Journal of Pharmacology, EarlyView.Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Insect Conservation and Diversity, EarlyView.Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...
