Studies have demonstrated adverse effects of global warming on aquatic ecosystems.
However, the effects of increased water temperature (IWT) on fish reproduction are still …

Rising and more variable global temperatures pose a challenge for biodiversity, with
reproduction and fertility being especially sensitive to heat. Here, we assessed the potential …

Invasive species may quickly colonize novel environments, which could be attributed to both
phenotypic plasticity and an ability to locally adapt. Reproductive traits are expected to be …

Aim The few fish species able to reproduce across wide osmotic ranges either plastically
acclimate sperm performance to, or are locally adapted to, different salinities. The invasive …

Reproduction of external fertilizing vertebrates is typically constrained to either fresh or salt
water, not both. For all studied amphibians and fishes, this constraint includes immotile …

For externally fertilising organisms in the aquatic environment, the abiotic fertilisation
medium can be a strong selecting force. Among bony fishes, sperm are adapted to function …

An alternation between diploid and haploid phases is universal among sexual eukaryotes.
Across this biphasic cycle, natural selection and sexual selection occur in both phases …

In externally fertilizing species, the gametes of both males and females are exposed to the
influences of the environment into which they are released. Sperm are sensitive to abiotic …

Evolutionary theory predicts that selection will favor phenotypic plasticity in sperm traits that
maximize fertilization success in dynamic fertilization environments. In species with external …

Medaka Oryzias latipes is a tiny euryhaline fresh water fish distributed in environments
differing widely in salinity. According to past reports, Oryzias latipes spermatozoa are not …
