With the burgeoning use of immune-based treatments for cancer, never has there been a
greater need to understand the tumour microenvironment within which immune cells …

Interactions among terrestrial carnivores involve a complex interplay of competition,
predation and facilitation via carrion provisioning, and these negative and positive pathways …

The metacommunity concept is an important way to think about linkages between different
spatial scales in ecology. Here we review current understanding about this concept. We first …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

Why do species live where they live? What determines the abundance and diversity of
species in a given area? What role do species play in the functioning of entire ecosystems …

Apex predators have experienced catastrophic declines throughout the world as a result of
human persecution and habitat loss. These collapses in top predator populations are …

The role of generalist predators in biological control remains controversial as they may not
only reduce pest populations but also disrupt biocontrol exerted by other natural enemies …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Interspecific killing among mammalian carnivores is common in nature and accounts for up
to 68% of known mortalities in some species. Interactions may be symmetrical (both species …

Although almost all prey live with many types of predator, most experimental studies of
predation have examined the effects of only one predator at a time. Recent work has …
