The longlegged ant (Anoplolepis gracilipes) is one of the most damaging invasive tramp
ants globally. It is generally found between latitudes 27° N and 27° S in Asia, although it has …

Extreme temperatures can constrain foraging behavior, and individual differences in thermal
tolerances may affect foraging performance within and among species. Ambient …

Collective phenotypes, which arise from the interactions among individuals, can be
important for the evolution of higher levels of biological organization. However, how a …

One neglected aspect of research on foraging behavior is that of the effect of obstacles that
increase habitat complexity on foraging efficiency. Here, we explored how long it takes …

In ants, workers of different sizes may perform various tasks, even in so‐called monomorphic
species with relatively low body size variation. However, it is unclear if the body size …

Experience can lead to faster exploitation of food patches through spatial learning or other
parallel processes. Past studies have indicated that hungry animals either search more …

Bees provide pollination services in both agricultural and natural ecosystems. However,
invasive ants that exploit floral nectar in these landscapes can compete with bees for …

Selection may favour traits throughout an individual's lifetime or at a particular life stage. In
many species of social insects, established colonies that are more genetically diverse …

Differences among groups in collective behavior may arise from responses that all group
members share, or instead from differences in the distribution of individuals of particular …

Animal behaviour often is characterised by standardised assays. In social insects such as
ants, behaviour assays are for example used to characterise aggressive and peaceful …
