Neogene Caribbean elasmobranchs: diversity, paleoecology and paleoenvironmental significance of the Cocinetas Basin assemblage (Guajira Peninsula, Colombia) [PDF]
Biogeosciences, 2019 The Cocinetas Basin is located on the eastern flank of the Guajira Peninsula, northern Colombia (southern Caribbean). During the late Oligocene through the Pliocene, much of the basin was submerged.

Ecology and Evolution, Volume 16, Issue 1, January 2026.Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

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.

Molecular phylogeny, including a new species of Anindobothrium (Cestoda, Rhinebothriidea) from the Southern eagle ray Myliobatis goodei, finally solves the taxonomic enigma of Phyllobothrium myliobatidis [PDF]
Zoosystematics and EvolutionDuring a parasitological survey of tapeworms from Myliobatis goodei Garman, 1885 (Myliobatiformes: Myliobatidae) in coastal waters off Argentina in the Southwestern Atlantic, a new rhinebothriidean cestode species, Anindobothrium danielae sp.

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.The lack of biometric data on chondrichthyan species has impeded the implementation of management strategies essential for the conservation of sharks and rays captured using different fishing gears in coastal ecosystems. This study aims to assess morphometric relationships (length–weight [LW], length–dorsal length [DL], and length–disc width [DW]) and ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...
