Optimizing a Novel eDNA‐Based Framework for Reef Fish Biodiversity Monitoring Using an Autonomous Filtration System and in situ Nanopore Sequencing

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study presents a comprehensive eDNA metabarcoding protocol optimized for monitoring fish biodiversity in coral reefs and other remote marine environments. By combining an autonomous underwater filtration system, Oxford Nanopore sequencing, and a 12S reference database specifically developed for French Polynesia, the method enables efficient and ...

The Neocolonial Tightening of CITES: How Northern Narratives Marginalize Southern Conservation

Conservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT CITES has demonstrated a persistent trend of regulatory tightening over five decades, raising critical questions about both equity and effectiveness in global conservation governance. This study examines how structural power imbalances and dominant Northern narratives within the Convention have systematically marginalized pluralistic ...

Dental Morphology, Palaeoecology and Palaeobiogeographic Significance of a New Species of Requiem Shark (Genus Carcharhinus) from the Lower Miocene of Peru (East Pisco Basin, Chilcatay Formation)

Journal of Marine Science and Engineering, 2022
Nowadays, the requiem sharks comprise one of the most diverse and widespread families of selachians, i.e., Carcharhinidae. Among the carcharhinids, the genus Carcharhinus has the largest number of living species, namely, at least 35.

Volitional Swimming Kinematics of Blacktip Sharks, Carcharhinus limbatus, in the Wild

Drones, 2020
Recent work showed that two species of hammerhead sharks operated as a double oscillating system, where frequency and amplitude differed in the anterior and posterior parts of the body. We hypothesized that a double oscillating system would be present in

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

Defining ecological roles of sharks on coral reefs

Biological Reviews, Volume 100, Issue 6, Page 2707-2725, December 2025.
ABSTRACT Sharks have often been perceived to play a critical role in the dynamics of coral reef ecosystems globally. Yet, there is relatively little evidence to support this idea across all but a limited set of species and contexts. Research on the roles and importance of reef sharks has been complicated by logistical challenges in collecting data on ...
