Novel Assay for Endangered Hong Kong Grouper (Epinephelus akaara) to Assess eDNA Shedding, Decay, and Population Status

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)

The Extinction Risk–Range Change Relationship: Evidence From the Fossil Record

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Climate change is a major driver for the wave of species extinctions predicted for this century. Extinction risk assessments are often estimated from climate‐driven reductions in the geographic ranges of species. However, the empirical relationship between extinction risk and range change remains unclear because few extinctions are ...

New vertebrate microfossils expand the diversity of the chondrichthyan and actinopterygian fauna of the Maastrichtian–Danian Hornerstown Formation in New Jersey [PDF]

open access: yesActa Palaeontologica Polonica
The abundance of shark and actinopterygian fossils in the Cretaceous and Paleogene strata of the Atlantic Coastal Plain is well documented; but much remains unknown about the survivorship patterns of these major components of shallow marine faunas in the

Conservation Value of Shallow‐Water Habitats for Rays Within a Long‐Standing Marine Protected Area

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Marine protected areas (MPAs) are a widely used tool in the conservation and protection of threatened marine species. When MPAs include the key habitat of species into their design, they can provide refuge and opportunity for recovery from exploitative pressures.

DNA barcoding unveils skate (Chondrichthyes: Rajidae) species diversity in ‘ray’ products sold across Ireland and the UK [PDF]

open access: yes, 2013
Skates are widely consumed across the globe, but many large species are subject to considerable concern regarding their conservation and management. Within Europe such issues have recently driven policy changes so that, for the first time, reports of ...

How Host Phylogeny and Diet Shape the Specificity and Specificity Diversity of Animal Gut Microbiomes

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
By identifying unique/enriched microbial species across taxa and diet types in 318 animal species with our SSD (specificity and specificity diversity) framework, we demonstrated that host phylogeny and diet are joint drivers of microbial specificity compositional heterogeneity, potentially linking the macroecological pattern of phylosymbiosis with the ...

Indigenous peoples and local community reports of climate change impacts on biodiversity

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

Fisheries Bycatch of Chondrichthyes

open access: yes, 2017
This chapter reviews the current state of knowledge about global chondrichthyes bycatch, including how the combination of biological characteristics of these species and the impact of different fishing methods reflect their vulnerability to bycatch.

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

open access: yesThe 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

Myocardial trabeculation in embryos of Scyliorhinus canicula (Elasmobranchii, Chondrichthyans) [PDF]

open access: yes, 2018
Currently, three types of ventricular myoarchitecture are recognized in vertebrates, namely compact, spongy (trabeculated) and mixed myocardium. Mixed myocardium, which has been recently proposed as the primitive condition in gnathostomes, is composed of
