The evolution of male traits in social insects.
Pair formation in social insects mostly happens early in adult life and away from the social colony context, which precludes promiscuity in the usual sense. Termite males have continuous spermExpand

Ant reproductive strategies
In contrast to what is generally believed, the reproductive strategies of ants are remarkably diverse and include such different phenomena, as wingless female and male sexuals, reproduction by matedExpand

Moribund Ants Leave Their Nests to Die in Social Isolation
Animal societies provide perfect conditions for the spread of infections and are therefore expected to employ mechanisms that reduce the probability of transmitting pathogens to group members [1-4].Expand

Clonal reproduction and genetic caste differences in a queen-polymorphic ant, Vollenhovia emeryi
Most social Hymenoptera are characterized by simple haploid sex determination and environment-based caste differentiation. This appears to be strikingly different in the queen-polymorphic antExpand

Worker rank, reproductive status and cuticular hydrocarbon signature in the ant, Pachycondyla cf. inversa
Abstract. Workers in de-queened colonies of the neotropical ant, Pachycondyla cf. inversa, form linear or near-linear dominance hierarchies by violent antennation and biting. In these rank orders,Expand

The coevolutionary dynamics of obligate ant social parasite systems — between prudence and antagonism
In this synthesis we apply coevolutionary models to the interactions between socially parasitic ants and their hosts. Obligate social parasite systems are ideal models for coevolution, because theExpand

Queen primer pheromone affects conspecific fire ant (Solenopsis invicta) aggression
Monogyne fire ant, Solenopsis invicta, colony Keywords Queen Aggression Execution Polygyny workers are territorial and are aggressive toward members of other fire ant colonies. In contrast, polygyneExpand

The Ecology of Communal Breeding: The Case of Multiple-Queen Leptothoracine Ants
Multiple-queen societies of ants are key subjects in the study of communal breeding. Societies of leptothoracine ants may be obligately monogynous (contain a single reproductive queen), functionallyExpand

The significance of latitudinal variation in body size in a holarctic ant, Leptothorax acervorum
The mean body size of workers of the holarctic ant Leptothorax acervorum increases with latitude. Workers from populations near the Polar Circle were 10% larger than workers from central Europe. ThisExpand

Evolution of male morphology in the ant genus Cardiocondyla.
The ant genus Cardiocondyla is characterized by a striking male polymorphism, with wingless, local fighter males (ergatoid males) with life-long spermatogenesis, and winged, peaceful disperser malesExpand
