Edward Grey Institute of Ornithology, Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK
Proc Biol Sci 274:853-60. 2007..These rapid within-male fluctuations may help explain the recent findings of trade-offs between male social and gametic competitive abilities and may help maintain phenotypic variability in these traits...

Male reproductive senescence causes potential for sexual conflict over matingRebecca Dean
Edward Grey Institute, Department of Zoology, University of Oxford, Oxford OX1 3PS, UK
Curr Biol 20:1192-6. 2010..Thus, male senescence causes potential for sexual conflict over mating, and the intensity of this conflict is modulated socially, by the probability of old males dominating reproductive opportunities...

Evolution and Ecology Group, School of Biological Sciences, University of Leeds, Leeds LS2 9JT, UK
Curr Biol 14:R511-3. 2004..Recent evidence indicates that this happens because females eject previously stored semen after a new copulation, revealing female bias in sperm use and the resulting battle of the sexes over fertilisation...
