The evolution of male traits in social insects.
An evolutionary framework for testing sexual selection and sperm competition theory across the advanced eusocial insects (ants, wasps, bees, termites) is developed and two areas related to premating sexual selection (sexual dimorphism and male mate number) that have remained understudied are highlighted.

Ant reproductive strategies
It appears that most deviations from “normal” colony propagation can be explained by a decreased success of dispersal and solitary founding by solitary queens in certain types of habitats.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Moribund Ants Leave Their Nests to Die in Social Isolation
The Ecology of Communal Breeding: The Case of Multiple-Queen Leptothoracine Ants
A framework for understanding multiplequeening in leptothoracines almost certainly results from high costs to single queens of dispersal and colony foundation (high ecological constraints), which select for queens to seek adoption in their natal colony.
Clonal reproduction and genetic caste differences in a queen-polymorphic ant, Vollenhovia emeryi
The queen-polymorphic ant Vollenhovia emeryi might provide an interesting model system to trace the evolution of unusual caste and sex determination systems.
The genome of the fire ant Solenopsis invicta
A phylogenetic analysis revealed that an ancestral vitellogenin gene first underwent a duplication that was followed by possibly independent duplications of each of the daughter viteLLogenins, possibly reflecting differential selection acting on the queen and worker castes.
Worker rank, reproductive status and cuticular hydrocarbon signature in the ant, Pachycondyla cf. inversa
It is shown that the composition of cuticular hydrocarbons of egg-l laying workers is quantitatively and qualitatively different from that of non-laying workers and resembles the hydrocarbon blend of the queen but does not completely match it.
Nest site limitation and colony takeover in the ant Leptothorax nylanderi
Investigation of the colony and population structure of the small, mynnicine ant Leptothorax (Myrafant) nylanderi in a deciduous forest near Wurzburg, Germany, where nest sites appear to be strongly limited, finds that nest sites become scarce in summer and both established colonies and young founding queens face a severe shortage of suitable nest sites.
