Omnivory, feeding at more than one trophic level, is a prevalent feature of freshwater
ecosystems. Understanding where and when omnivory is important, its relevance for …

Ecological understanding of the role of consumer–resource interactions in natural food webs
is limited by the difficulty of accurately and efficiently determining the complex variety of food …

Optimal foraging theory predicts that predators are selective when faced with abundant prey,
but become less picky when prey gets sparse. Insectivorous bats in temperate regions are …

Variation in prey resources influences the diet and behaviour of predators. When prey
become limiting, predators may travel farther to find preferred food or adjust to existing local …

Zoophytophagy (true omnivory) is a ubiquitous behavior. It allows plant-feeding predators to
maximize their development by finding essential nutrients, and to survive when animal …

Abstract Knowledge gaps regarding the potential role of pesticides in the loss of agricultural
biodiversity worldwide and mixture-related issues hamper proper risk assessment of …

Generalist species with numerous food web interactions are thought to provide stability to
ecosystem dynamics; however, it is not always clear whether habitat generality translates …

Understanding the feeding behaviour of the species that make up any ecosystem is
essential for designing further research. Mammals have been studied intensively, but the …

As extreme generalists, cockroaches mix their diet from foods that vary greatly in their
nutrient composition. It might thus be predicted that these insects have evolved robustness …

Under current climate trends, spring ice breakup in Hudson Bay is advancing rapidly,
leaving polar bears (Ursus maritimus) less time to hunt seals during the spring when they …
