Animal personalities or behavioural syndromes are consistent and/or correlated behaviours
across two or more situations within a population. Social insect biologists have measured …

Individuals within social groups often show consistent differences in behaviour across time
and context. Such interindividual differences and the evolutionary challenge they present …

Here, we reveal an unanticipated role of the blood-brain barrier (BBB) in regulating complex
social behavior in ants. Using scRNA-seq, we find localization in the BBB of a key hormone …

Social insects are important models for social evolution and behavior. However, in many
species, experimental control over important factors that regulate division of labor, such as …

Social insects frequently engage in oral fluid exchange–trophallaxis–between adults, and
between adults and larvae. Although trophallaxis is widely considered a food-sharing …

Infochemicals, including hormones, pheromones, and allelochemicals, play a central role in
mediating information and shaping interactions within and between individuals. Due to their …

Olfactory circuits change structurally and physiologically during development and adult life.
This allows insects to respond to olfactory cues in an appropriate and adaptive way …

Division of labor (DOL) is a characteristic trait of insect societies, where tasks are generally
performed by specialized individuals. Inside workers focus on brood or nest care, while …

Ant-infecting Ophiocordyceps fungi are globally distributed, host manipulating, specialist
parasites that drive aberrant behaviors in infected ants, at a lethal cost to the host. An …

This paper introduces a conceptual framework for the evolution of complex systems based
on the integration of regulatory network and niche construction theories. It is designed to …
