Arthropods are an important component of grassland systems, contributing significantly to
biodiversity and ecosystem structure and function. Climate, fire, and grazing by large …

Grasshoppers are insect herbivores common to grassland ecosystems worldwide. They
comprise important components of biodiversity, contribute significantly to grassland function …

Climate change is expected to alter trophic interactions within food chains, but predicting the
fate of particular species is difficult because the predictions hinge on knowing exactly how …

Why is the World green–what keeps herbivores, and herbivorous insects in particular, from
consuming all of their food? When this question was first posed, the relative importance of …

Mutualism can facilitate the colonization, establishment, and spread of invasive species. By
modifying interactions with third parties, mutualisms can have cascading community-wide …

Cascading effects of predators on total plant trophic‐level biomass tend to be weaker in
terrestrial than in aquatic systems. Accordingly, it is hypothesized that top predator effects on …

Because both intrinsic and extrinsic factors influence insect population dynamics, operating
at a range of temporal and spatial scales, it is difficult to assess their contributions. Long …

The ecological consequences of climate change are determined by many climate
parameters, not just by the commonly investigated changes in mean temperature and …

Aim To assess effects of current global temperature and precipitation gradients on the
trophic function of plant–herbivore–predator interactions. Specifically, I study effects of …

Climate change can affect species directly and indirectly by altering interactions between
species within communities. These indirect effects can ramify through a community and …
