In insects, olfaction plays a crucial role in many behavioral contexts, such as locating food,
sexual partners, and oviposition sites. To successfully perform such behaviors, insects must …

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

Ants live in organized societies with a marked division of labor among workers, but little is
known about how this division of labor is generated. We used a tracking system to …

Human brain size nearly quadrupled in the six million years since Homo last shared a
common ancestor with chimpanzees, but human brains are thought to have decreased in …

How do ant colonies get anything done, when no one is in charge? An ant colony operates
without a central control or hierarchy, and no ant directs another. Instead, ants decide what …

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

Abstract 'Division of labor'is a misleading way to describe the organization of tasks in social
insect colonies, because there is little evidence for persistent individual specialization in …

Division of labor is a complex phenomenon observed throughout nature. Theoretical studies
have focused either on its emergence through self-organization mechanisms or on its …

Division of labor, the specialization of workers on different tasks, largely contributes to the
ecological success of social insects [1, 2]. Morphological, genotypic, and age variations …
