The tribal and generic classification of the diverse ant subfamily Ponerinae (Hymenoptera:
Formicidae) is revised to reflect recent molecular phylogenetic information and a reappraisal …

▪ Abstract Social Hymenoptera show two contrasting strategies of colony reproduction. A
reproductive female can raise the first generation of brood alone (independent foundation) …

In insect societies lacking morphologically specialized breeders and helpers, reproduction is
often restricted to behaviorally dominant individuals. Such societies occur in about 100 …

We review the different levels of reproductive conflict within ant societies. Workers and
queens may disagree about sex allocation and the origin of males. Other conflicts arise …

Several decades of research in humans, other vertebrates, and social insects have offered
fascinating insights into the dynamics of punishment (and its subset, policing), but authors …

According to the classic life history theory, selection for longevity depends on age-
dependant extrinsic mortality and fecundity. In social insects, the common life history trade …

In social Hymenoptera with no morphological caste, a dominant female becomes an egg
layer, whereas subordinates become sterile helpers. The physiological mechanism that links …

In many social hymenopteran species, workers possess functional ovaries that are
physiologically inactive in the presence of queens. We investigated the ovarian regulatory …

Being social and living in groups is often advantageous over leading a solitary life. At the
same time, however, cooperative systems are susceptible to exploitation and cheating by …

In a variety of social animals, individuals can secure reproductive rights through aggressive
