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.

Microscopic Analysis of Mustelus schmitti´s Uteri During Reproductive Cycle
Annual Research & Review in Biology, 2015 Aims: It was analysed with light and electron microscopy the different zones of the Mustelus schmitti`suteri along the reproductive cycle. Study Design: Histological routine techniques were used. Place and Duration of Study: Specimens of Mustelus schmitti were collected from the Bahia Blanca estuary, each month, from 2002 to 2006.
