Status and trends in the structure of Arctic benthic food webs [PDF]

, 2015
Ongoing climate warming is causing a dramatic loss of sea ice in the Arctic Ocean, and it is projected that the Arctic Ocean will become seasonally ice-free by 2040.

Trophic Structure and the Isotopic Niche Dynamics of the Tasiujaq (Eclipse Sound, Nunavut, Canada) Marine Food Web

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 9, September 2025.
ABSTRACT Rapid warming in the Arctic is causing cumulative impacts on ecosystems, including widespread reduction in sea ice extent, resulting in shifts in primary production, which can have cascading bottom‐up trophic influences on marine food web structure and function. Understanding trophic interactions and the structure of local food webs across the

Habitat and Trophic Specialization Among Greenland Cod (Gadus ogac) Morphotypes in the Context of Climate Change Resilience

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Morphological variation and habitat‐trophic metrics from carbon (δ13C) and nitrogen (δ15N) stable isotopes were estimated in Greenland cod (Gadus ogac) collected along the marine coast near Ulukhaktok, NT, in the western Canadian Arctic. This study provides critical insights into the ability of coastal Arctic Gadids to respond to shifts in resource use

Spring phenology of the Arctic Ocean shelf production system

Communications Earth & Environment
The shelf areas of the Arctic Ocean host some of the world’s most productive marine ecosystems, yet their under-ice early-season phenology and inter-trophic dynamics remain poorly understood amid rapid climate change.

Status and biology of harbour seals (Phoca vitulina) in Svalbard

NAMMCO Scientific Publications, 2010
Harbour seals in Svalbard are the northernmost population of this species. This small population is comprised of ca. 1,000 individuals, most of which reside along the west coast of Prins Karls Forland (78°20’N). Satellite tracking studies have shown that

Spatial Distribution of Numerical Density of Pelagic Juveniles (0‐Group) of Broadcast Spawning Fish Stocks Follows a Common Statistical Pattern

Fish and Fisheries, Volume 26, Issue 5, Page 717-732, September 2025.
ABSTRACT Statistical distributions of spatial abundance data of animal populations can be informative about underlying processes and mechanisms that govern the spatial distributions. Here, we examine a large data set from annual 0‐group fish surveys in the Barents Sea (1980–2017) collected with standardised trawl sampling from a regular grid with 30–35

Impact of dispersed fuel oil on cardiac mitochondrial function in polar cod Boreogadus saida

Environmental Science and Pollution Research, 2014
In this study, impact of dispersed oil on cardiac mitochondrial function was assessed in a key species of Arctic marine ecosystem, the polar cod Boreogadus saida. Mature polar cod were exposed during 48 h to dispersed oil (mechanically and chemically) and dispersants alone.

Inclusivity of Indigenous Knowledge Systems in Fisheries Management

Fish and Fisheries, Volume 26, Issue 4, Page 669-687, July 2025.
ABSTRACT Indigenous Peoples have developed knowledge systems that foster respectful and reciprocal relations between humans and other‐than‐human beings, supporting resilient ecosystems and societies. Despite the impacts of colonisation, Indigenous Knowledge Systems (IKS) endure in many parts of the world, and there is growing recognition that IKS can ...

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

Journal of Fish Biology, Volume 107, Issue 1, Page 143-160, July 2025.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...
