Seascape Connectivity Shapes Genetic and Species β‐Diversity in Tropical Reef Fishes
Ecology and Evolution, Volume 16, Issue 6, June 2026.Our study combines species occurrence data from five reef fish families with genomic SNP data for 19 species. A correlation between genetic and species β‐diversity emerges only in the Western Indian Ocean, where higher genetic β‐diversity and significant isolation by distance at both the population and community levels are detected.

Marine Parasite Biogeography Mirrors Host Patterns Across Latitude, Area, and Diversity
New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.Parasites are integral components of biodiversity, yet they remain poorly represented in large‐scale biogeographic theory. In this study, we test whether marine parasites follow three macroecological patterns established for free‐living taxa, namely that parasite species richness: (1) scales positively with area (both host body size and geographic area)

Fisheries Bycatch of Chondrichthyes
, 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.

Evolutionary Stability of the Shark Snout: Geometric Morphometrics of Ventral Facial Openings
Annals of the New York Academy of Sciences, Volume 1560, Issue 1, June 2026.Landmark‐based geometric morphometrics of 453 shark species reveal that ventral head morphology is conserved across Selachii. Morphospace and ancestral reconstructions support strong phylogenetic control and limited divergence from ancestral conditions.

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

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the

Environmental DNA, Volume 8, Issue 3, May–June 2026.Community diversity metrics revealed a clear ecological gradient, with the highest diversity observed in recolonized mature stands, intermediate in the natural stands, and lowest in the restored stands. Taxonomic profiles varied with mangrove stand, age, and zonation.

Conservation Science and Practice, Volume 8, Issue 5, May 2026.This study combines literature and online data sources to expand the smalleye stingray's range, highlight ecological interactions and specific threats. Abstract Many chondrichthyan fishes are experiencing alarming population declines primarily due to overfishing, exacerbated by their inherently vulnerable life history traits including slow growth rates

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings
Fish and Fisheries, Volume 27, Issue 3, Page 591-606, May 2026.ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as
