Does female feeding motivation affect the response to a food-mimicking male ornament in the swordtail characin Corynopoma riisei?

abstract：:Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild population dynamics, fisheries and aquaculture. In this extensive review spanning tropical and cold-w...
