Data from: Population density and structure drive differential investment in pre- and postmating sexual traits in frogs
- 负责人:
- DOI:
- doi:10.5061/dryad.10nk0
- 摘要:
- Sexual selection theory predicts a trade-off between premating (ornaments and armaments) and postmating (testes and ejaculates) sexual traits
Data from: Maternal obesity increases insulin resistance, low-grade inflammation and osteochondrosis lesions in foals and yearlings until 18 months
- 负责人:
- DOI:
- doi:10.5061/dryad.s8g04
- 摘要:
- , as well as offspring growth, metabolism, low-grade inflammation, testicular maturation and osteochondrotic lesions until 18 months of age were investigated. Twenty
Data from: Anticipatory flexibility: larval population density in moths determines male investment in antennae, wings and testes
- 负责人:
- DOI:
- doi:10.5061/dryad.qp5g7
- 摘要:
- ment in testes size depended on the number of individuals, while male investment in wings and antennae depended upon larval density. In contrast, the size of female
Data from: Experimental evolution reveals that sperm competition intensity selects for longer, more costly sperm

- DOI:
- doi:10.5061/dryad.22rh6
- 摘要:
- for spermatogenesis in the testis. Here, we empirically examine how sperm competition shapes sperm size, after more than 77 generations of experimental selection
Data from: Polyandry, predation, and the evolution of frog reproductive modes
- 负责人:
- DOI:
- doi:10.5061/dryad.v67g3
- 摘要:
- , testes mass was significantly larger and more variable in males with exposed amplexus that are vulnerable to polyandry. Our results indicate tha
Data from: Sperm production characteristics vary with level of sperm competition in Cataglyphis desert ants
- 负责人:
- DOI:
- doi:10.5061/dryad.v7000
- 摘要:
- er of spermatozoa stored in their accessory testes at emergence is thus a reliable measure of total investment into sperm production. In a comparative study of 15
Data from: Differential investment in pre- versus post-copulatory sexual selection reinforces a cross-continental reversal of sexual size dimorphism
- 负责人:
- DOI:
- doi:10.5061/dryad.49mf6
- 摘要:
- and consequently have evolved relatively larger testes and steeper hyper-allometry with body size. American populations, in sharp contrast, display muc
Data from: Genetic dissection of hybrid male sterility across stages of spermatogenesis
- 负责人:
- DOI:
- doi:10.5061/dryad.vd6k4b2
- 摘要:
- and genetic determinants of hybrid male sterility from a developmental perspective, we characterized testis histology in 312 F2 hybrids generate
Data from: Steroid hormones in hair reveal sexual maturity and competition in wild house mice (Mus musculus domesticus)

- 摘要:
- to older females and increased with the level of visible injuries or scars. Testosterone in males positively correlated with body weight, age, testes
Data from: Seasonally sympatric but allochronic: differential expression of hypothalamic genes in a songbird during gonadal development
- 负责人:
- DOI:
- doi:10.5061/dryad.5d9s571
- 摘要:
- ong the HPG axis. During the sympatric pre-breeding stage, we measured hypothalamic and testicular mRNA expression of candidate genes via qPCR in captive male juncos
