Large herbivores play unique ecological roles and are disproportionately imperiled by
human activity. As many wild populations dwindle towards extinction, and as interest grows …

Global change is impacting forests worldwide, threatening biodiversity and ecosystem
services including climate regulation. Understanding how forests respond is critical to forest …

Human activities are fundamentally altering biodiversity. Projections of declines at the global
scale are contrasted by highly variable trends at local scales, suggesting that biodiversity …

Large mammalian herbivores (megafauna) have experienced extinctions and declines since
prehistory. Introduced megafauna have partly counteracted these losses yet are thought to …

Niche partitioning facilitates species coexistence in a world of limited resources, thereby
enriching biodiversity. For decades, biologists have sought to understand how diverse …

Abstract Motivation The BioTIME database contains raw data on species identities and
abundances in ecological assemblages through time. These data enable users to calculate …

Herbivory is a key process structuring vegetation in savannas, especially in Africa where
large mammal herbivore communities remain intact. Exclusion experiments consistently …

Global biodiversity assessments have highlighted land-use change as a key driver of
biodiversity change. However, there is little empirical evidence of how habitat …

Understanding how predation risk and plant defenses interactively shape plant distributions
is a core challenge in ecology. By combining global positioning system telemetry of an …

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 …
