Insects are among the most diverse and widespread animals across the biosphere and are
well‐known for their contributions to ecosystem functioning and services. Recent increases …

Insect pests continue to exact a high toll on agricultural production, in spite of intense
agrochemical input. The movement of insect pests from one place to another underlies their …

Population sizes of generalist consumers are increasing in many ecosystems because of
various human activities, and it is critical to understand the trophic role of these generalist …

Host ranges are commonly quantified to classify herbivores and plant pathogens as either
generalists or specialists. Here, we summarize patterns and mechanisms in the interactions …

The diverse ecology of parasitoids is shaped by extrinsic competition, ie, exploitative or
interference competition among adult females and males for hosts and mates. Adult females …

Aim To quantify spatio‐temporal changes in species richness and assemblage composition
of Danish butterflies over more than 100 years and to assess whether different functional …

Inferences of the interactions between species' ecological niches and spatial distribution
have been historically based on simple metrics such as low-resolution dietary breadth and …

Abstract The tribe Dacini (Diptera: Tephritidae) contains over 930 recognised species and
has been widely studied due to the economic importance of some taxa, such as the Oriental …

Specialisms on resources and for niches, leading to specialization, have been construed to
be tantamount to speciation and vice versa, while the occurrence of true generalism in …

Recognizing how different species react to environmental changes provides fundamental
information for conservation biology. Population and distribution trends in changing …
