- 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, background): “Experimental removal of sexual selection, and hence removal of sperm competition, did lead to changes in testis size in two species of Diptera (Hosken and Ward 2001; Hosken et al. 2001; Pitnick et al. 2001; Snook 2001).”
- No evidence that sexual selection is an ‘engine of speciation’ in birds (2003, methodology): “We use relative testes size as a measure of the intensity of post-mating sexual selection (Parker 1998; Hosken & Ward 2001), because this trait is widely accepted to be a reliable predictor of the rate of extra-pair paternity and as such the intensity or risk of sperm competition (Møller & Briskie…”
- Measuring relative investment: a case study of testes investment in species with alternative male reproductive tactics (2002, methodology): “Selection on testes investment has also been investigated by direct manipulations of sperm competition risk in selected lines of Drosophila melanogaster (Pitnick et al. 2001) and yellow dung flies, Scatophaga (Scathophaga) stercoraria ( Hosken & Ward 2001 ).”
- Strategic ejaculation in the common dung fly Sepsis cynipsea (2002, background): “In addition, experimental evidence in two fly species also indicates that testis size evolves in accordance with theory (Hosken & Ward 2001; Hosken et al. 2001; Pitnick et al. 2001), and, for Scathophaga stercoraria, males with larger testes were better in sperm competition (Hosken et al. 2001).”
- Variation in paternity in the field cricket Teleogryllus oceanicus: no detectable influence of sperm numbers or sperm length (2003, background): “Subsequent microevolutionary experiments (Hosken and Ward, 2001; Hosken et al., 2001) suggest that sperm length may not be important in sperm competition for this species, because experimental removal of sperm competition via enforced monogamy resulted in decreased sperm production but had no influe”
