• Intrasexual selection and group spawning in quacking frogs (Crinia georgiana) (2004, background): “First, they will provide an insight into the evolution of group spawning, a mating system that may be widespread amongst anurans yet remains largely uninvestigated (cf. Byrne et al., 2002, 2003; Halliday, 1998).”
• Human sperm competition: testis size, sperm production and rates of extrapair copulations (2004, background): “Across species, increased risk (the average probability that females will copulate with more than one male) and intensity (the average number of different males with which females copulate) of sperm competition are expected to favour increased male expenditure on sperm production (Parker 1998), a pa”
• Parental investment, sexual selection and sex ratios (2008, background): “Although males often do invest more in competitive traits in species when competition is intense (e.g. Weckerly, 1998; Byrne et al., 2002; Lindenfors et al., 2002; Bro-Jørgensen, 2007), something is amiss if biologists can use the same logic to reach two diametrically opposed conclusions.”
• Bigger testes do work more: experimental evidence that testis size reflects testicular cell proliferation activity in the marine invertebrate, the free-living flatworm Macrostomum sp. (2004, methodology): “Studies aimed at testing this theory have mainly used static measures of male allocation, such as testis weight (Warner and Robertson 1978; Harcourt et al. 1981; Møller 1988a, 1988b; Gage 1994, 1995; Pitnick and Markow 1994a; Petersen and Fischer 1996; Pitnick 1996; Hosken 1997, 1998; Stockley et al”
• Phenotypic plasticity in sperm production rate: there’s more to it than testis size (2007, background): “In fact, many studies use testis size and sperm production interchangeably without testing this assumption (e.g. Pitnick et al. 2001; Byrne et al. 2002; Newlon et al. 2003; Malo et al. 2005; Minder et al. 2005), whereas other studies explicitly state that they make this assumption (e.g. Hellriegel…”
