Social evolution in ants
An overview of the current state of scientific knowledge about social evolution in ants is presented and how studies on ants have contributed to an understanding of many fundamental topics in behavioural ecology and evolutionary biology is shown. Expand

Worker Reproduction in the Higher Eusocial Hymenoptera

  • The Quarterly Review of Biology
  • 1 September 1988
The analysis of data assembled on 49 ant species reveals that workers in monogynous species (i.e., with one queen per colony) reproduce moslty in queenless conditions, whereas those in polygynous species reproduce in queensless and queenright conditions equally often, in agreement with kinship theory.

Kin conflict over caste determination in social Hymenoptera
It is argued that caste determination, the process whereby females in the social Hymenoptera develop into either queens or workers, is subject to kin-selected conflict, and two contexts leading to potential caste conflict are suggested. Expand
Alternative adaptations, sympatric speciation and the evolution of parasitic, inquiline ants
It is concluded that inquiline species strictly following Emery's rule could have evolved by the intraspecific route, and such species provide evidence for West-Eberhard's “alternative adaptation” hypothesis that between-species diversity frequently stems from diversity within species. Expand
Worker matricide in social bees and wasps
Worker matricide represents an extreme form of kin-selected queen-worker conflict over sexual production and is favoured by annual life cycles, late-season colonies, declining queen productivity, male-only production by queens, and single mating. Expand
Genetic analysis of spatial foraging patterns and resource sharing in bumble bee pollinators
It is concluded that urban habitats support large bumble bees populations and are potentially valuable in terms of bumble bee conservation, and bumblebee‐mediated gene flow in plants is likely to occur over large distances and plant–bumble bee conservation requires landscape‐scale action. Expand
Parentage, reproductive skew and queen turnover in a multiple–queen ant analysed with microsatellites
The fine genetic structure of colonies of the ant, Leptothorax acervorum, is investigated to examine how queens share parentage in a social insect with multiple queens (polygyny), finding that surprisingly many sexual progeny were not the offspring of the extant queens within their colonies. Expand
The genomes of two key bumblebee species with primitive eusocial organization
Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation. Expand
Hamilton's rule and the causes of social evolution

  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B…
  • 19 May 2014
Evidence for Hamilton's rule is provided by presenting novel syntheses of results from two kinds of study in diverse taxa, including cooperatively breeding birds and mammals and eusocial insects, and comparative phylogenetic analyses of the genetic, life-history and ecological correlates of sociality.
