Paternal environment effects are driven by female reproductive fluid but not sperm age in an external fertilizer
Sperm ageing after ejaculation can generate paternal environment effects that impact
offspring fitness. In many species, female reproductive fluids (FRFs), ie ancillary fluids …

Sperm specificity and potential paternal effects in gynogenesis in the Amazon Molly (Poecilia formosa)
C Cerepaka, I Schlupp - PeerJ, 2023 - peerj.com
Abstract The Amazon Molly (Poecilia formosa) reproduces by gynogenesis, a relatively rare
form of asexual reproduction where sperm is required to trigger embryogenesis, but male …

Post-ejaculatory environmental effects on sperm phenotype and reproductive fitness in a broadcast spawning marine invertebrate
J Hadlow - 2024 - research-repository.uwa.edu.au
The post-ejaculatory environment, ie, either in the female reproductive tract for internal
fertilisers or in an external medium for external fertilisers, can be very hostile for sperm cells …
