J Theor Biol 264:1003-23. 2010..However, unless controlled for the effects of risk, the relation between m(*) and s(*) can be either positive or negative (a positive relation is usually taken as evidence against a size-number trade off)...
Why do larval helminths avoid the gut of intermediate hosts?G A Parker

Male "mixed" reproductive strategies in biparental species: Trivers was probably right, but why?G A Parker
Population and Evolutionary Biology Research Group, University of Liverpool, Liverpool L69 7ZB, United Kingdom
Am Nat 165:95-106. 2005..Nevertheless, most species conform to the model's criterion regarding relative parentage levels in broods of social versus extrapair mates. Patterns of extrapair parentage thus appear sufficient to stabilize biparental care systems...

'Sloppy' sperm mixing and intraspecific variation in sperm precedence (P2) patternsI F Harvey
School of Biological Sciences, University of Liverpool, UK
Proc Biol Sci 267:2537-42. 2000..Sloppy mixing can thus result in many of the observed P2 distributions. Sloppy mixing is unlikely to change the predictions of adaptive models of sperm competition...

Population and Evolutionary Biology Research Group, School of Biological Sciences, University of Liverpool, Liverpool, UK
J Evol Biol 16:47-54. 2003..Growth under competition appears comparable with "the tragedy of the commons", much analysed in social sciences. Our LHS prediction suggests that evolution generates a solution that seems cooperative but is actually selfish...
