When multiple victim species (eg prey, host) are attacked by one or more shared enemy
species (eg predator, pathogen), the potential exists for apparent competition between victim …

Ecologists have quantified Orthoptera (grasshoppers and crickets) density in a wide variety
of conservation studies. Objective determination of Orthoptera population size is possible …

Trophic cascades are regarded as important signals for top‐down control of food web
dynamics. Although there is clear evidence supporting the existence of trophic cascades, the …

Predators of herbivorous animals can affect plant populations by altering herbivore density,
behavior, or both. To test whether the indirect effect of predators on plants arises from …

Current theory on trophic interactions in food webs assumes that ecologically similar species
can be treated collectively as a single functional unit such as a guild or trophic level. This …

The grasshopper family Acrididae is one of the most diverse lineages within Orthoptera,
including more than 6,700 valid species distributed worldwide. Grasshoppers are dominant …

The influence of predation on rocky intertidal community structure has long emphasized the
importance of indirect interactions. Most efforts in this area have focused on the density …

Summary 1 Several recent studies have considered the relative effects of local vs.
landscape factors on diversity of several animal taxa in grasslands. However, very few have …

Understanding the effects of land-use on threatened ecosystems is of special relevance for
nature conservation. The aim of our study was to use Orthoptera as ecological indicators for …

Habitat selection behavior is affected by complex interplays between competing
requirements. Here we combine field observations with laboratory experiments to examine …
