- DOI：
- doi:10.5061/dryad.7cr21
- 摘要：
- , we detected effects of the selection regime for two male morphological traits. Specifically, worms evolving under enforced monogamy had a distinct shape
Data from: HIPK4 is essential for murine spermiogenesis

- 摘要：
- for sperm head shaping and male fertility in mice. HIPK4 is expressed in round and early elongating spermatids. Hipk4 knockout males are sterile, exhibiting
Data from: Testis asymmetry in birds: the influences of sexual and natural selection

- 摘要：
- but significant negative relation between the degree of size and shape asymmetries. In extant species, testis size and shape symmetries increase
Data from: Micropyle number is associated with elevated female promiscuity in Lepidoptera

- DOI：
- doi:10.5061/dryad.2c5m1
- 摘要：
- could explain profound micropylar variation: (i) increasing micropyle number reduces the risk of infertility through sperm limitation in species that mate
Data from: Sibling rivalry: males with more brothers develop larger testes

- 摘要：
- of enforced monogamy in captivity. While these results suggest that differences in sperm production between species with divergent evolutionary histories

- 摘要：
- New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shape
Data from: Female behavior and the interaction of male and female genital traits mediate sperm transfer during mating.

- 摘要：
- Diploid organisms manipulate the extent to which their haploid gametes experience selection. Animals typically produce sperm with a diploid
Data from: Demography or selection on linked cultural traits or genes? Investigating the driver of low mtDNA diversity in the sperm whale usi

- 摘要：
- social structures, counteracting even high mobility, abundance and limited barriers to dispersal. One such species is the sperm whale, which shows very limited
Data from: Developmental diet irreversibly shapes male post-copulatory traits in the neriid fly (Telostylinus angusticollis)

- DOI：
- doi:10.5061/dryad.0215pq7
- 摘要：
- within the female reproductive tract and sperm length in the neriid fly, Telostylinus angusticollis. We found that males fed a nutrient-poor developmental diet produced sperm
