  1. ncbi Unicolonial ants: where do they come from, what are they and where are they going?
    Heikki Helantera
    Department of Biological and Environmental Sciences, PO Box 65 Viikinkaari 1, University of Helsinki, FI 00014 Helsinki, Finland
    Trends Ecol Evol 24:341-9. 2009
    ..However, at extreme sizes, kin selection theory predicts that these behaviors are maladapted and evolutionarily unstable, a prediction that is supported by their twiggy phylogenetic distribution...
  2. ncbi Worker reproduction in the ant Formica fusca
    H Helantera
    Department of Biological and Environmental Sciences, University of Helsinki, Helsinki, Finland
    J Evol Biol 18:162-71. 2005
    ..Our results suggest that worker reproduction in F. fusca is ultimately an interplay of conflicts over male parentage and sex allocation and that both worker and self policing have roles as proximate mechanisms of resolution...
  3. ncbi Geometry explains the benefits of division of labour in a leafcutter ant
    Heikki Helantera
    Department of Biological and Environmental Sciences, University of Helsinki, University of Helsinki, Finland
    Proc Biol Sci 275:1255-60. 2008
    ..Third, the size of fruit pieces cut increases approximately in proportion to the cube of mandible length. Our results are a novel mechanistic example of how size variation among worker ants enhances division of labour...
  4. ncbi Sex allocation conflict in insect societies: who wins?
    Heikki Helantera
    Laboratory of Apiculture and Social Insects, Department of Biological and Environmental Science, University of Sussex, Falmer, Brighton BN1 9QG, UK
    Biol Lett 5:700-4. 2009
    ..We suggest future work for analysing power in the conflict between queen and workers over sex allocation and discuss the extent of male power...
  5. ncbi Do unicolonial wood ants favor kin?
    Heikki Helantera
    Department of Biological and Environmental Sciences, University of Helsinki, Helsinki, Finland
    J Biol 8:56. 2009

    Margaret J Couvillon
    Laboratory of Apiculture and Social Insects, School of Life Sciences, University of Sussex, Falmer, Brighton, UK
    J Chem Ecol 36:1306-8. 2010

    Laboratory of Apiculture and Social Insects, Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK

    Heikki Helantera
    Department of Biological and Environmental Sciences, University of Helsinki, Helsinki, Finland
    Am Nat 170:E14-25. 2007

    Francis L W Ratnieks
    Laboratory of Apiculture and Social Insects, Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK
    J Theor Biol 244:470-7. 2007
    ..Our model is an example where an explicit treatment of underlying genetics and mechanisms of behaviour, such as information use, is necessary to fully understand the evolution of an adaptive behavioural strategy...
