Environmentally induced stress affects fitness of bold and shy alike: A long‐term study of personality and feather corticosterone in Arctic‐breeding kittiwakes

Journal of Animal Ecology, EarlyView.
Quantifying how individuals differ as their environment changes around them is crucial to predict population responses to climate change. By incorporating personality, physiology and life‐history the authors show that while environmental change is likely to impact the whole population equally, when individuals are most impacted will vary across the ...

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Genetic structure of sugar kelp in the St. Lawrence Estuary and Gulf (Québec, Canada)

Journal of Phycology, EarlyView.
Abstract The sugar kelp, Saccharina latissima, is cultivated at low scale in Quebec, Canada, and current practice involves seeding meiospores or gametophyte stocks onto spools carrying twine and transferring these to a seaweed farm site. As the stocks can originate from locations spanning several hundreds of kilometers from the farm sites, such ...

Tidewater glaciers as feeding spots for the Black-legged Kittiwake (Rissa tridactyla): A citizen science approach

Polish Polar Research, 2020
Thirty-one tidewater glacier bays in Spitsbergen Island were visited by yachts in August 2011, 2015, 2016 and 2017. Surface water samples were taken by volunteers, the members of the yacht crews, to measure concentrations of suspended matter, salinity,

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.

Retracing the Response of Rangifer to Postglacial Climate Change in Arctic Islands

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Our study examines the role of sea ice and glacial retreat in shaping the biogeography of Rangifer tarandus across Arctic islands since the last glacial period. Using mitochondrial DNA analysis and approximate Bayesian computation (ABC) modelling, we found that Arctic island dispersal occurred during the Holocene, with sea ice cover likely influencing ...
