  1. pmc Life history and the evolution of family living in birds
    Rita Covas
    Institute of Evolutionary Biology, University of Edinburgh, Edinburgh EH9 3JT, UK
    Proc Biol Sci 274:1349-57. 2007
    ..We therefore propose that both life-history and ecological factors play a role in determining the evolution of family living across species, yet we suggest different mechanisms than those proposed by previous models...

    ..However, the survival function was not symmetric, indicating that body mass might not be under stabilizing selection as suggested previously...

    Centre d Ecologie Fonctionnelle et Evolutive, Centre National de Recherche Scientifique, Unite Mixte de Recherche 5175, 1919 Route de Mende, 34293 Montpellier Cedex 5, France
    Am Nat 172:441-8. 2008
    ..Because mark-recapture models provide an explicit way to integrate and reliably model the detection process, we strongly recommend their use to address questions in evolutionary biology...

    Matthieu Paquet
    CEFE CNRS, 1919 Route de Mende, Montpellier, France
    PLoS ONE 8:e59336. 2013
    ..Taken together, these results suggest that the environment created by helpers can influence maternal allocation and potentially offspring phenotypes...

    Rita Covas
    Percy FitzPatrick Institute, University of Cape Town, Rondebosch 7701, South Africa
    Proc Biol Sci 271:827-32. 2004
    ..Hence, these results also provide evidence for a direct influence of reproductive costs on life-history decisions such as age at first reproduction and breeding and helping behaviours...

    Rita Covas
    Percy FitzPatrick Institute, University of Cape Town, Rondebosch 7701, South Africa
    Proc Biol Sci 269:1905-9. 2002
    ..We present evidence for strong stabilizing selection on body mass, verifying the prediction that body mass probably results from a trade-off between the risks of starvation at low mass and predation at high mass...
