- 摘要:
- male age and body mass differences, O. cornuta males produced on average ?175’000 spermatozoa that were ?65% viable, which are both significantly lower
Data from: Moderate heritability and low evolvability of sperm morphology in a species with high risk of sperm competition, the collared flycatcher

- 摘要:
- Spermatozoa represent the morphologically most diverse type of animal cells and show remarkable variation in size across and also within spe
Data from: The Azores Bullfinch (Pyrrhula murina) has the same unusual and size-variable sperm morphology as the Eurasian Bullfinch (Pyrrhula

- 摘要:
- ow that the spermatozoa of the two species have similar ultrastructure and gross morphology. Thus, the unusual and supposedly neotenous sperm morphology pr
Data from: Sperm is a sexual ornament in rose bitterling

- 摘要:
- bitterling mate choice and we propose that sperm acts as a releaser pheromone in bitterling, functioning as a sexual ornament signalling male quality as a mate.
