The lifespan of spermatozoa from externally fertilizing freshwater fish ranges from a few
seconds to several minutes, depending on the species. External factors, such as …

Factors such as gamete quality can profoundly affect fertility, but the spawning micro-
environment that surrounds the spermatozoa and eggs during gamete contact has largely …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

Highlighting the growing importance of the sticklebacks as a model species in emerging
fields such as molecular genetics, genomics, and environmental toxicology, Biology of the …

In species with internal fertilization, females can favour certain males over others, not only
before mating but also within the female's reproductive tract after mating. Here, we ask …

Organisms exposed to altered salinity must be able to perceive osmolality change because
metabolism has evolved to function optimally at specific intracellular ionic strength and …

Female mate choice after copulation or spawning is cryptic when a female differentially
influences the fertilization success of sperm from different males. We tested whether ovarian …

Sperm cryopreservation is a highly efficient method for preserving genetic resources. It
extends the reproductive period of males and significantly reduces costs normally …

Polyandrous mating systems result in females mating with multiple males, generating
opportunities for strong pre‐mating and post‐mating sexual selection. Polyandry also …

In polyandrous mating systems, females maintain the opportunity to bias male fertilization
success after mating in a process known as cryptic female choice. Mechanisms of cryptic …
