Effective conservation of species and ecosystems requires the understanding of important
ecological traits, such as dietary habits, food webs, and trophic niches. In diet studies, the …

Food webs are a major focus and organizing theme of ecology, but the data used to
assemble them are deficient. Early debates over food-web data focused on taxonomic …

Ecological niche differences are necessary for stable species coexistence but are often
difficult to discern. Models of dietary niche differentiation in large mammalian herbivores …

Dietary selection and intake affect the survival and health of mammals under extreme
environmental conditions. It has been suggested that dietary composition is a key driver of …

Populations of the world's largest carnivores are declining and now occupy mere fractions of
their historical ranges. Theory predicts that when apex predators disappear, large …

Over recent decades, ungulate populations across Europe have undergone a rapid
recovery. While this constitutes a conservation success, there is increasing concern about …

Individual decisions regarding how, why and when organisms interact with one another and
with their environment scale up to shape patterns and processes in communities. Recent …

Extreme weather events perturb ecosystems and increasingly threaten biodiversity.
Ecologists emphasize the need to forecast and mitigate the impacts of these events, which …

Large mammalian carnivores have undergone catastrophic declines during the
Anthropocene across the world. Despite their pivotal roles as apex predators in food webs …

Trophic rewilding seeks to rehabilitate degraded ecosystems by repopulating them with
large animals, thereby re-establishing strong top-down interactions. Yet there are very few …
