In a rapidly changing world, ecology has the potential to move from empirical and
conceptual stages to application and management issues. It is now possible to make large …

One challenge in merging community and ecosystem ecology is to integrate the complexity
of natural multitrophic communities into concepts of ecosystem functioning. Here, we …

Many human influences on the world's ecosystems have their largest direct impacts at either
the top or the bottom of the food web. To predict their ecosystem‐wide consequences we …

Herbivorous top-down forces and bottom-up competition for nutrients determine the
coexistence and relative biomass patterns of producer species. Combining models of …

The study of the determinants of biomass pyramids (ie, the patterns of biomass of organisms
at different trophic levels of an ecosystem) within and across ecosystems is an enduring …

The development of new methods and approaches for ensuring the sustainability of
agriculture and ecosystem services is an important challenge that ecologists, agronomists …

We performed a meta‐analysis of 31 lake mesocosm experiments to investigate differences
in the responses of pelagic food chains and food webs to nutrient enrichment and fish …

Human activities may compromise biodiversity if external stressors such as nutrient
enrichment endanger overall network stability by inducing unstable dynamics. However …

Background Food web composition and resource levels can influence ecosystem properties
such as productivity and elemental cycles. In particular, herbivores occupy a central place in …

Scavenging can have important consequences for food web dynamics, for example, it may
support additional consumer species and affect predation on live prey. Still, few food web …
