Data from: Dunnock social status correlates with sperm speed, but fast sperm does not always equal high fitness

- DOI:
- doi:10.5061/dryad.ncjsxksrh
- 摘要:
- average speed of sperm cells per sample, we also analyzed subsamples of the fastest sperm cells per sample. In other words, we systematically evaluated the effect
Data from: Long sperm fertilize more eggs in a bird

- DOI:
- doi:10.5061/dryad.dc335
- 摘要:
- hough sperm size and swimming velocity are known to independently affect fertilization success in certain species, exploring the relationship bet
Data from: Male body size and condition affects sperm number and production rates in mosquitofish, Gambusia holbrooki
- 负责人:
- DOI:
- doi:10.5061/dryad.sf651
- 摘要:
- ts sperm production rates. We counted sperm number in large and small Gambusia holbrooki (eastern mosquitofish) after 3 weeks on either a high or low food diet
Data from: Sperm head abnormalities are more frequent in songbirds with more helical sperm: A possible trade-off in sperm evolution
- 负责人:
- St?stad, Hanna
- DOI:
- doi:10.5061/dryad.1mj39tf
- 摘要:
- cies with more pronounced helical sperm have higher average sperm swimming speed, our results suggest an evolutionary trade-off between sperm perform
Data from: Postcopulatory sexual selection is associated with accelerated evolution of sperm morphology
- 负责人:
- DOI:
- doi:10.5061/dryad.qb2c7
- 摘要:
- the speed of evolutionary diversification in sperm form is unknown. Using passerine birds, we quantified evolutionary rates of sperm length divergence amo
Data from: Sperm duct gland contents increase sperm velocity in the sand goby
- 负责人:
- DOI:
- doi:10.5061/dryad.pp68kp4
- 摘要:
- d a paired experimental design, with spermatozoa tested with and without sperm duct gland contents mixed into seawater. We measured sperm velocity, per
Data from: Strategic adjustments in sperm production within and between two island populations of house mice
- 负责人:
- DOI:
- doi:10.5061/dryad.87pk2
- 摘要:
- Sperm production is physiologically costly. Consequently, males are expected to be prudent in their sperm production, and tailor their expe
Data from: The effects of male age, sperm age and mating history on ejaculate senescence
- 负责人:
- DOI:
- doi:10.5061/dryad.8p502cr
- 摘要:
- male age (3, 9, and 14 weeks post-maturation) and their interaction on sperm velocity, sperm reserves, and the rate of sperm replenishment
Data from: Male sperm storage compromises sperm motility in guppies
- 负责人:
- DOI:
- doi:10.5061/dryad.n687q
- 摘要:
- (Poecilia reticulata). We show that older sperm exhibit significant reductions in sperm velocity compared with younger sperm from the same males. We found no evidence
Data from: Sperm head morphology is associated with sperm swimming speed: a comparative study of songbirds using electron microscopy

- 摘要:
- h sperm swimming speed and the frequency of extra-pair young (EPY). We found that species whose sperm had a relatively more pronounced helical form
