Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

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.
