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

open access: yesEcology 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 Overlooked Threat of Global Warming on Elasmobranch Fertility

open access: yesFish 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.

Hopping Hotspots Shaped the Global Biogeography and Diversification of Orectolobiform Sharks

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim In marine biogeography, many clades exhibit their greatest species richness in the Central Indo‐Pacific region, which includes the Indo‐Australian Archipelago. However, there is no consensus that this region was the ancestral cradle of clade's species richness.

Ecological function of the Ariake Bay as a scalloped hammerhead shark (Sphyrna lewini) nursery in the northwestern Pacific

open access: yesGlobal Ecology and Conservation
The scalloped hammerhead (Sphyrna lewini), a cosmopolitan shark inhabiting temperate and tropical waters, is highly vulnerable to fisheries owing to late maturity and low reproductive output.

Measuring juvenile habitat quality for fishes and invertebrates

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2346-2395, December 2025.
ABSTRACT Identifying the role of marine and estuarine habitats in supporting fish and invertebrate populations during vulnerable juvenile life stages is essential to achieve effective conservation and fisheries management. There remains general agreement that: (i) the quality of juvenile habitat is best measured as the contribution of juveniles to ...

Rapid DNA/eDNA‐Based ID Tools for Improved Chondrichthyan Monitoring and Management

open access: yesMolecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Rapid DNA/eDNA‐based ID tools, which detect specific genetic patterns without requiring sequencing, are essential for biodiversity and wildlife trade monitoring, particularly for species of conservation concern. However, the practical application of these methods remains limited by the availability of standardised protocols, accessibility of ...

A new species of Abdounia (Elasmobranchii, Carcharhinidae) from the base of the Boom Clay Formation (Oligocene) in northwest Belgium [PDF]

open access: yes, 2007
On the basis of isolated teeth, collected from the base of the Boom Clay Formation (Rupelian, Oligocene) at the SVK clay pit (Sint-Niklaas, NW Belgium), a new species of requiem shark, Abdounia belselensis sp. nov., is described.

Eutetrarhynchid trypanorhynchs (Cestoda) from elasmobranchs off Argentina, including the description of Dollfusiella taminii sp. n. and Parachristianella damiani sp. n., and amended description of Dollfusiella vooremi (São Clemente et Gomes, 1989) [PDF]

open access: yes, 2014
During a parasitological survey of teleosts and elasmobranchs in the Argentine Sea, 3 species of eutetrarhynchids were collected from the batoids Myliobatis goodei Garman and Psammobatis bergi Marini, and the shark Mustelus schmitti Springer.
