Data from: Stabilizing selection on sperm number revealed by artificial selection and experimental evolution
- 负责人:
- Cattelan, Silvia
- DOI:
- doi:10.5061/dryad.23r95
- 摘要:
- in the competing pool the prime predictor of fertilization success. Despite the strong postcopulatory selection acting directionally on sperm production, its geneti
Data from: Sperm variation within a single ejaculate affects offspring development in Atlantic salmon

- 摘要:
- to select for sperm cohorts differing in longevity within single ejaculates of wild caught male salmon. We found that within-ejaculate variation in sperm
Data from: Unravelling anisogamy: egg size and ejaculate size mediate selection on morphology in free-swimming sperm

- 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: Conspecific sperm precedence is reinforced, but postcopulatory sexual selection weakened, in sympatric populations of Drosophila

- DOI:
- doi:10.5061/dryad.n88kb1m
- 摘要:
- to outcompete heterospecific sperm, consistent with selection for increased postcopulatory isolation. We also find these D. pseudoobscura populations hav
Data from: Experimental evolution reveals that sperm competition intensity selects for longer, more costly sperm

- doi:10.5061/dryad.22rh6
- 摘要:
- , it is theorized that widespread sperm competition leads to selection for investment in sperm numbers, achieved by minimizing sperm size within limited resources
Data from: Positive selection on sperm ion channels in a brooding brittle star: consequence of life-history traits evolution
- 负责人:
- DOI:
- doi:10.5061/dryad.713q3
- 摘要:
- ons surrounding sperm in the brooding species, either directly affecting sperm, or via an increase in male/female conflict. This phenomenon could have promoted
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:
- to respond to selection. We then investigated whether polyandry can evolve through sexually selected sperm processes. We measured lifetime polyandry
Data from: Postcopulatory sexual selection is associated with accelerated evolution of sperm morphology

- 摘要:
- on and the speed of sperm evolution, and suggest that postcopulatory sexual selection promotes rapid evolutionary diversification of sperm morphology.
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
Data from: Sperm blocking is not a male adaptation to sperm competition in a parasitoid wasp

- 摘要:
- the mechanics of processing sperm in this species, which are likely shaped by selection on female reproductive morphology for adaptive sex allocation.
