Hormones reflect the impacts of reproductive rest on subsequent pregnancy in a marine predator
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract After reaching sexual maturity, iteroparous female vertebrates may intermittently skip producing offspring, effectively taking a year of reproductive rest. This may confer benefits to lifetime fitness by enhancing future reproductive success.

International Journal of Molecular Sciences, 2013 Several evidences supported the existence of melatonin effects on reproductive system in fish. In order to investigate whether melatonin is involved in the modulation of GnRH systems in the European sea bass, we have injected melatonin (0.5 μg/g body ...

Emerging Perspectives on Gonadotropin Regulation in Vertebrates Revealed by the Discovery of FSH-RH in Teleosts. [PDF]
BioessaysRegarding pituitary gonadotropin regulation, recent studies have shown that in mammals, FSH and LH are regulated by a single GnRH (solo GnRH model), whereas in teleosts, they are regulated by CCK (FSH‐RH) and GnRH (LH‐RH), respectively (dual GnRH model).
