Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

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

Hatching Strategies in Monogenean (Platyhelminth) Parasites that Facilitate Host Infection [PDF]

, 2011
In parasites, environmental cues may influence hatching of eggs and enhance the success of infections. The two major endoparasitic groups of parasitic platyhelminths, cestodes (tapeworms) and digeneans (flukes), typically have high fecundity, infect more

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 ...
