The Overlooked Threat of Global Warming on Elasmobranch Fertility
Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.
