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.

Testing biodegradable interventions to disrupt plant–animal feedbacks and promote seagrass establishment

Restoration Ecology, Volume 34, Issue 1, January 2026.
Biogeochemical and physical feedbacks are well known to prevent ecosystem recovery even after initial disturbance factors are mitigated. However, multi‐trophic interactions that may maintain disturbed areas have received less attention, despite their potential importance in mediating restoration success. In this study, we surveyed stingray feeding pits

Digital Conservation Can Fill Data Gaps in Data‐Poor Regions: Case of Elasmobranchs in India

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 11, November 2025.
ABSTRACT Internet and social media use have increased significantly over the past decade, resulting in huge volumes of biodiversity data that are potentially cost‐effective means to better inform biodiversity conservation and resource management. We examine the role of digital conservation in a data‐poor context of the Global South, using sharks and ...
