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: 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
Data from: The biomechanical basis of evolutionary change in a territorial display

- 摘要：
- speed among species. Between islands, however, differences in dewlap speed were most likely the result of a major increase in muscle contraction velocity

- 摘要：
- in response behaviour was discernible. As vehicle speed increased, cowbirds did not have enough time to assess the approaching vehicle, and cowbirds
Data from: Flight paths of seabirds soaring over the ocean surface enable measurement of fine-scale wind speed and direction

- 摘要：
- on soaring seabirds to record their tracks. Seabirds were accelerated by tail winds or slowed down by head winds during flight, so their flight speed changed
Data from: Early diversification of sperm size in the evolutionary history of the old world leaf warblers (Phylloscopidae)

- 摘要：
- e is known about the evolutionary dynamics of sperm morphology, and whether rates of evolutionary change are variable over time and among taxonomic groups. Here, we examine spe

Data from: Measuring sperm swimming performance in birds: effects of dilution, suspension medium, mechanical agitation, and sperm number
- 负责人：
- DOI：
- doi:10.5061/dryad.662kb6m
- 摘要：
- Sperm swimming performance, including swimming speed and the proportion of motile cells, may strongly affect fertilization success. However, littl
Data from: Optimal running speeds when there is a trade-off between speed and the probability of mistakes
