Abstract:Males often strategically modify their rate of sperm production based on the social context, but it remains unclear how environmental and genetic factors shape this plasticity. In freshwater ecosystems, high ambient temperatures often lead to isolated pools of hotter water in which inbreeding occurs. Higher water temperatures and inbreeding can impair fish development, potentially disrupting sperm production. We used guppies (Poecilia reticulata) to investigate how developmental temperature (26°C or 30°C) and … Show more
