TL;DR: The effects caused by different insect invaders are reviewed according to their ecosystem roles, i.e. herbivores, predators, parasites, parasitoids and pollinators; the level of biological organisation at which they occur; and the direct and indirect mechanisms underlying these effects.

TL;DR: Higher levels of taxonomic resolution will be sufficient for detecting the impacts of disturbance in lineages of terrestrial arthropods with higher levels of phylogenetic constraint, although this does not negate the necessity and importance of species‐level identifications in situations with sufficient resources and where study questions demand alpha taxonomy.

TL;DR: The emerald ash borer is a serious exotic pest of ash trees (Fraxinus spp.) in North America, and is responsible for the deaths of millions of trees in Ontario and Michigan.

TL;DR: A view of the forest canopy that is heterogeneous with respect to arthropod refuge from natural enemies is supported, although treatment effects were small for some taxa.

TL;DR: A wide variety of latitudinal patterns are demonstrated, reflecting the ecological variation between subfamilies, and host taxon and subfamily identities are better predictors of the shape of the relationship between subfamily abundance and latitude than other characteristics that have been previously hypothesised to be important.
