Exposure of wildlife to anticoagulant rodenticides (ARs) has been extensively documented
for species directly or indirectly linked to pest rodents via the terrestrial food web. Recently …

Long‐lived top predators shape biodiversity structure in their ecosystems and predator–prey
interactions are critical in decoding how communities function. Studies on the foraging …

Declining emissions of persistent organic pollutants (POPs), subject to international control
under the Stockholm convention, are not consistently reflected in biotic samples. To assess …

Predator populations are imperiled globally, due in part to changing habitat and trophic
interactions. Theoretical and laboratory studies suggest that heterogeneous landscapes …

Otters are semi-aquatic mammals specialized in feeding on aquatic prey. The Eurasian otter
Lutra lutra is the most widely distributed otter species. Despite a low degree of genetic …

Optimal foraging theory predicts that carnivores select prey species based on intrinsic
factors, such as body size, vulnerability, and abundance. Prey abundance can vary …

Toxic metals have been linked to a range of adverse health effects in freshwater organisms.
However, for higher vertebrates, there is little understanding of the large-scale drivers of …

Eurasian otters are apex predators of freshwater ecosystems and a recovering species
across much of their European range; investigating the dietary variation of this predator over …

Concentrations of 33 PFASs were determined in 20 Eurasian otters, sampled 2015–2019,
along a transect away from a factory, which used PFOA in PTFE manufacture. Despite …

Background Protozoan pathogens from the genus Cryptosporidium cause the diarrhoeal
disease cryptosporidiosis in humans and animals globally. Freshwater biota could act as …
