Data from: Male body size and condition affects sperm number and production rates in mosquitofish, Gambusia holbrooki

- 摘要：
- Sperm number is an important predictor of paternity when there is sperm competition. Sperm number is often measured as maximum sperm reser
Data from: No support for the sexy?sperm hypothesis in the seed beetle: sons of monandrous females fare better in post?copulatory competition

- 摘要：
- ortant in sperm competition within certain species. Previous empirical work has revealed such genetic constraints in the seed beetle

- doi:10.5061/dryad.5pc00
- 摘要：
- competitiveness could be attributed exclusively to differences in the sperm competitive ability of focal males, a conclusion supported by subsequent analyses
Data from: Male sperm storage compromises sperm motility in guppies
- 负责人：
- DOI：
- doi:10.5061/dryad.n687q
- 摘要：
- competitiveness is lacking. Here, we used a paired experimental design that compares sperm quality between ‘old’ and ‘young’ ejaculates from individual male guppies
Data from: Additive genetic variance in polyandry enables its evolution, but polyandry is unlikely to evolve through sexy or good sperm processes
- 负责人：
- DOI：
- doi:10.5061/dryad.p0j5k
- 摘要：
- Polyandry is widespread despite its costs. The sexually selected sperm hypotheses (‘sexy’ and ‘good’ sperm) posit that sperm competition plays a role
Data from: Polyandrous females provide sons with more competitive sperm: support for the sexy-sperm hypothesis in the rattlebox moth (Utetheisa
- 负责人：
- DOI：
- doi:10.5061/dryad.vb14q
- 摘要：
- t female multiple mating and male sperm competitiveness co-evolve via a Fisherian runaway process. We tested the sexy-sperm hypothesis by using competitive
Data from: A general description of additive and non-additive elements of sperm competitiveness and their relation to male fertilization success
- 负责人：
- DOI：
- doi:10.5061/dryad.g7q12
- 摘要：
- . Genuine conclusions on male sperm competitiveness can only be made in real competitive situations. However, statistical analyses of sperm competitiveness
Data from: Do sperm really compete and do eggs ever have a choice? Adult distribution and gamete mixing influence sexual selection, sexual conflict
- 负责人：
- DOI：
- doi:10.5061/dryad.c57rf
- 摘要：
- males directly compete for an egg and whether eggs ever have a choice. Direct sperm competition and egg choice depend on whether sperm from different
Data from: Evolutionary change in testes tissue competition among experimental populations of house mice
- 负责人：
- DOI：
- doi:10.5061/dryad.3t082
- 摘要：
- increase the chance of success in sperm competition, and larger testes are able to produce more sperm. However, changes in the organization of the testes
Data from: Flexible memory controls sperm competition responses to male Drosophila melanogaster
- 负责人：
- DOI：
- doi:10.5061/dryad.1q52r71
- 摘要：
- Males of many species use social cues to predict sperm competition and tailor their reproductive strategies, such as ejaculate or behavioural
