Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Evidence for a fisher‐designed solution to manta and devil ray bycatch in tuna fisheries

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Bycatch in global tropical tuna purse seine fisheries represents a significant source of mortality for manta and devil rays (mobulids), which are globally threatened. Use of best handling and rapid release practices on purse seine vessels can substantially reduce mortality and improve vulnerability status for mobulids.

Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Complete Mitochondrial Genome of the Araucanian Herring, Strangomera bentincki, Norman, 1936 (Teleostei: Clupeiformes: Clupeidae): Phylogenetic Analysis and Implications in Fishmeal Traceability

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Araucanian herring (Strangomera bentincki) is a pelagic fish whose main processed products are fishmeal and oil. The complete mitogenome is 16,758 bp, consisting of 13 coding genes, two rRNAs, 22 tRNAs, and the control region. Phylogenetic analysis supported a monophyletic clade with Sprattus muelleri and Sprattus antipodum.
