Data from: Differential sperm storage by female zebra finches Taeniopygia guttata
- 负责人：
- DOI：
- doi:10.5061/dryad.46bq0
- 摘要：
- When females mate promiscuously, female sperm storage provides scope to bias the fertilization success towards particular males via the non-random
Data from: Intra-ejaculate sperm selection in female zebra finches

- 摘要：
- Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching
Data from: Early diversification of sperm size in the evolutionary history of the old world leaf warblers (Phylloscopidae)

- doi:10.5061/dryad.rj25q
- 摘要：
- Sperm morphological traits are highly variable among species and are commonly thought to evolve by post-copulatory sexual selection. However, littl
Data from: Tactic-specific differences in seminal fluid influence sperm performance

- DOI：
- doi:10.5061/dryad.1pb77
- 摘要：
- Seminal fluid often makes up a large part of an ejaculate, yet most empirical and theoretical studies on sperm competition have focused on how sperm
Data from: A competitive environment influences sperm production, but not testes tissue composition, in house mice
- 负责人：
- DOI：
- doi:10.5061/dryad.tg386p7
- 摘要：
- Due to the physiological cost of sperm production, males are expected to be prudent in their expenditure and adjust their investment accordin
Data from: Female-induced remote regulation of sperm physiology may provide opportunities for gamete-level mate choice
- 负责人：
- DOI：
- doi:10.5061/dryad.151r7
- 摘要：
- ween sexes occur largely at the gamete level. Certain combinations of eggs and sperm often have higher fertilization success than others, which ma
Data from: Phenotypic plasticity in genitalia: baculum shape responds to sperm competition risk in house mice
- 负责人：
- DOI：
- doi:10.5061/dryad.57v6627
- 摘要：
- Males are known to adjust their expenditure on testes growth and sperm production in response to sperm competition risk. Genital morphology can als
Data from: A study of the transit amplification divisions during spermatogenesis in Oncopeltus fasciatus to assess plasticity in sperm number

- DOI：
- doi:10.5061/dryad.q57n9h7
- 摘要：
- males maintained late-life fertility. We tested the hypothesis that older milkweed-fed males maintained fertility by producing more, higher quality sperm
Data from: Unravelling anisogamy: egg size and ejaculate size mediate selection on morphology in free-swimming sperm

- DOI：
- doi:10.5061/dryad.2bj8g
- 摘要：
- the size-related selection pressures of sperm competition and zygote survival, assuming that fertilization of all eggs precludes selection for phenotypes tha
Data from: Ejaculate evolution in external fertilizers: influenced by sperm competition or sperm limitation?
- 负责人：
- DOI：
- doi:10.5061/dryad.t5jp7
- 摘要：
- The evolution of sperm quality and quantity is shaped by various selective processes, with sperm competition generally considered the primary
