Abstract Ants (Hymenoptera: Formicidae) are one of the most dominant terrestrial organisms
worldwide. They are hugely abundant, both in terms of sheer numbers and biomass, on …

The importance of interspecific competition is a highly controversial and unresolved issue for
community ecology in general, and for phytophagous insects in particular. Recent …

Comprising a substantial part of living biomass on earth, ants are integral to the functioning
of terrestrial ecosystems. More than 12,000 species have been described to date, and it is …

Interactions between ants and honeydew-producing hemipteran insects are abundant and
widespread in arthropod food webs, yet their ecological consequences are very poorly …

With an expanding human population placing increasing pressure on the environment,
agriculture needs sustainable production that can match conventional methods. Integrated …

Arthropod generalist predators (AGP) are widespread and abundant in both aquatic and
terrestrial ecosystems. They feed upon herbivores, detritivores, and predators, and also on …

Non‐native ants can cause ecosystem‐wide ecological change, and these changes are
generally assumed to be negative. Despite this, the evidence base has never been …

Historic and current land-use changes have altered the landscape for grassland biota, with
over 90% of grasslands and savannas converted to agriculture or some other use in north …

Indirect defence, the adaptive top‐down control of herbivores by plant traits that enhance
predation, is a central component of plant–herbivore interactions. However, the scope of …

Abstract Agricultural landscapes in North America have developed through complex
interactions of biophysical, socioeconomic and technological forces. While they can be …
