The evolution of male traits in social insects.
TLDR
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. Expand
Ant reproductive strategies
TLDR
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. Expand
Inclusive fitness theory and eusociality
TLDR
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
TLDR
It is shown that workers of the ant Temnothorax unifasciatus dying from fungal infection, uninfected workers whose life expectancy was reduced by exposure to 95% CO(2)[6, 7], and workers dying spontaneously in observation colonies exhibited the same suite of behavior of isolating themselves from their nestmates days or hours before death.

Clonal reproduction and genetic caste differences in a queen-polymorphic ant, Vollenhovia emeryi
TLDR
The queen-polymorphic ant Vollenhovia emeryi might provide an interesting model system to trace the evolution of unusual caste and sex determination systems. Expand
Electrochemistry of conducting polymers--persistent models and new concepts.
TLDR
Electropolymerization in Novel Electrolytic Media 4745: Influence of the Polymerization Technique, Influence of Experimental Conditions, and Specific Phenomena of n-Doping. Expand
The coevolutionary dynamics of obligate ant social parasite systems — between prudence and antagonism
TLDR
This synthesis applies coevolutionary models to the interactions between socially parasitic ants and their hosts, finding that queen‐tolerant and queen‐intolerant inquilines and slavemakers are ideal models for coev evolution. Expand
Worker rank, reproductive status and cuticular hydrocarbon signature in the ant, Pachycondyla cf. inversa
TLDR
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. Expand
Queen primer pheromone affects conspecific fire ant (Solenopsis invicta) aggression
TLDR
It is proposed that the powerful effect of fire ant queens on conspecific nestmate recognition is caused by a queenproduced recognition primer pheromone that increases the sensitivity of workers to subtle quantitative differences in nestmate recolgnition cues. Expand
The genome of the fire ant Solenopsis invicta
TLDR
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. Expand
