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.

Foreword to Supplement 1: research on a polar species—the Arctic fox

Polar Research, 2017
The Arctic fox has a circumpolar distribution and is intensively studied because it is adapted to extreme environments and influences the ecology of many other species.

Predation Risk Does Not Delay Breeding but Reduces Nest Survival in High‐Arctic Shorebirds

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We assessed the impact of arctic foxes' predation pressure on two sympatric sandpiper species. Fox activity influenced the breeding ecology of both sandpipers, with earlier nest initiations and lower nest survival rates in areas of high fox activity. ABSTRACT Understanding predator–prey interactions is crucial for correctly answering many fundamental ...

Nutrient digestibility in Arctic fox (Vulpes lagopus) fed diets containing animal meals

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Three digestibility experiments on Arctic foxes were carried out. Control groups were fed standard diets (C1 and C2) composed of fresh or frozen animal by-products and steamed ground grain.

Fox dietary ecology as a tracer of human impact on Pleistocene ecosystems.

PLoS ONE, 2020
Nowadays, opportunistic small predators, such as foxes (Vulpes vulpes and Vulpes lagopus), are well known to be very adaptable to human modified ecosystems. However, the timing of the start of this phenomenon in terms of human impact on ecosystems and of

A Gnawing Question: How Do Caribou and Other Arctic Mammals Exploit Shared Bone Resources?

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Bones of dead animals are consumed by many species, yet the partitioning of this resource, and the associated ecological and evolutionary implications, remains poorly understood. Using bone modification features found on shed female caribou (Rangifer tarandus) antlers and skeletal bones lying on caribou calving grounds of the Arctic National Wildlife ...

Evolution and Climate Adaptation in Eurasian Gyrfalcon Populations

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This reports the influence of past, current and future Arctic climate change to the evolution of Eurasian gyrfalcons (Falco rusticolus), and reveals that its current evolutionary potential is insufficient to cope with the ongoing Arctic warming. ABSTRACT Climate change is considered a key driver for shaping ecological and evolutionary processes of ...

Foxes in Retrospect—Unraveling Human-Fox Relationships through Fox Tooth Ornaments in the Swabian Jura

Quaternary, 2023
Personal ornaments play an important role in our understanding of human cultural and behavioral change during the Upper Paleolithic, providing insights into intangible aspects of human cultural behavior. Some ornament forms are better studied than others,

Dynamics and persistence of rabies in the Arctic

Polar Research, 2019
Rabies is a major issue for human and animal health in the Arctic, yet little is known about its epidemiology. In particular, there is an ongoing debate regarding how Arctic rabies persists in its primary reservoir host, the Arctic fox (Vulpes lagopus ...
