Impact of Tusk Anomalies on the Long-Term Foraging Ecology of Narwhals. [PDF]

Ecol Evol
We combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...

High Cost and Low Trust: Insights From Qualitative Commercial Fishing Cost Data in the Northeast United States

Fisheries Management and Ecology, Volume 33, Issue 4, Page 665-680, August 2026.
ABSTRACT In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey.

A Holistic Framework for the Protection and Management of Seagrass Meadows as Natural Assets of the Sea of Marmara

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Seagrass meadows in the Sea of Marmara (SoM) are under unprecedented ecological stress due to cumulative anthropogenic pressures and climate‐driven changes, exacerbated by recent large‐scale disturbances such as the 2021 mucilage event. Their degradation threatens biodiversity, coastal stability and the broader ecological integrity of the ...

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

Environmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

Widespread decline in the abundance of sea cucumber assemblages in atolls of the protected Rowley Shoals, northwestern Australia

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The Rowley Shoals, off northwestern Australia, are renowned as a biodiversity hotspot. This remote system comprises three atolls, Clerke, Imperieuse and Mermaid, which in recent years have been increasingly targeted by illegal fishing, a pressure rising across the Indo‐Pacific.

Genetics in the Ocean's Twilight Zone: Population Structure of the Silvery Lightfish Across Its Distribution Range

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

Fish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

Decarbonizing Fisheries Through Ensuring Healthy Stock Status

Fish and Fisheries, Volume 27, Issue 2, Page 370-380, March 2026.
ABSTRACT Industrial capture fisheries depend on fossil fuels, which tend to dominate both greenhouse gas emissions and operational costs of this form of seafood production. Improving energy efficiency is, in addition to shifting to alternative fuels, a crucial path towards decarbonizing fisheries.

Spatial Variability in Year‐to‐Year, Near‐Bottom Hypoxia Over the United States Pacific Northwest Continental Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The continental shelf off the northwest coast of North America experiences seasonal upwelling driven by summertime southward winds. Nutrient‐rich, low‐oxygen water is upwelled onto the shelf from a depth of about 150 m seaward of the continental shelfbreak.

Frequency of consumption of different fish, crustacean and mollusc species contributing to methylmercury exposure and consumer awareness of national advice on their consumption

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract Following a request of the European Commission, EFSA assessed fish and other seafood consumption patterns and consumer awareness of related health risks and benefits across the 27 Member States, Iceland and Norway. Awareness of existence of consumption national advice and to which extent this advice influence consumers consumption behaviour ...
