Photo-ID as a tool for studying and monitoring the endangered Saimaa ringed seal

Endangered Species Research, 2016
Photo-identification (photo-ID) with camera traps was examined as a non-invasive method for studying and monitoring the endangered Saimaa ringed seal Phoca hispida saimensis.

Avian influenza overview March–May 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Between 28 February and 4 June 2026, 949 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (186) and wild (763) birds in 30 countries in Europe. The downward trend in the number of detections observed at the end of the previous reporting period continued and is expected to persist throughout the summer ...

A Bayesian approach to include Indigenous Knowledge and satellite telemetry data in habitat selection functions

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our work points to the importance of both Western science and IK data sources in models used for conservation and management decisions. We show how the models that include the IK result in more informed predictions and the value of IK when predicting important areas for species that may be relied upon for conservation and management decisions.

A novel tool to mitigate by-catch mortality of baltic seals in coastal fyke net fishery.

PLoS ONE, 2015
Developing methods to reduce the incidental catch of non-target species is important, as by-catch mortality poses threats especially to large aquatic predators.

Haulout patterns of Saimaa ringed seals and their response to boat traffic during the moulting season

Endangered Species Research, 2013
Conservation of the Critically Endangered ringed seal Phoca hispida saimensis population in Lake Saimaa in Finland requires broader knowledge of the behavioural ecology of this subspecies.

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.

Top‐Down and Bottom‐Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology

Ecology Letters, Volume 29, Issue 3, March 2026.
This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

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 ...

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,

Notes From the Era of Pre‐Modern Fishing in the Baltic Sea Reveal an Extensive and Resilient Fishing Mode

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT In the past half‐century, fishing in one regional part of the Baltic Sea, the Stockholm Archipelago, has almost disappeared due to falling fish abundance, especially of herring (Clupea harengus). By examining published observations and archived material on historical fishing patterns, we found evidence of a remarkably continuous high level of ...
