2D to 3D: Exploring Variation of Niche Dimensionality Across Consumers in a Coastal Arctic Ecosystem and Implications on Interpretation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.

Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Novel terrestrial haul-out behaviour by ringed seals (Pusa hispida) in Svalbard, in association with harbour seals (Phoca vitulina)

Polar Research, 2017
Ringed seals (Pusa hispida) are the most ice-associated of all Arctic pinnipeds. In the Svalbard area, this species has always given birth, moulted and rested on sea ice. In addition, much of their food has been comprised of ice-associated prey. Recently,

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Foraging Ecology and Contaminant Burdens of Ringed Seals (Pusa hispida) in the Central Canadian Arctic [PDF]

, 2020
Increasing temperatures have led to declines in the extent of Arctic sea ice. Due to their reliance on sea ice and central position within Arctic marine food webs, ringed seals (Pusa hispida) are particularly vulnerable to these climate-mediated changes.
