Polar Research, 2017 Climate change can have a marked effect on the distribution and abundance of some species, as well as their interspecific interactions. In 1992, before ecological effects of anthropogenic climate change had developed into a topical research field ...

Why are Svalbard Arctic foxes Brucella spp. seronegative?
Polar Research, 2022 Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed to such bacteria through the consumption of infected marine mammals, as implied by the finding of s-Brucella antibodies in polar bears (Ursus ...

Polar Research, 2017 Three decades have passed since the Arctic fox (Vulpes lagopus) was first put into a population genetic perspective. With the aim of addressing how microevolution operates on different biological levels, we here review genetic processes in the Arctic fox

Foxes engineer hotspots of wildlife activity on the nutrient-limited Arctic tundra
Global Ecology and Conservation, 2022 Predators largely affect ecosystems through trophic interactions, but they also can have indirect effects by altering nutrient dynamics and acting as ecosystem engineers. Arctic foxes (Vulpes lagopus) are ecosystem engineers that concentrate nutrients on

Behavioural responses of a gamebird to human encounters across the hunting season
Wildlife Biology, EarlyView.We examined the behavioural adaptation of rock ptarmigan Lagopus muta in response to human encounters across the hunting season. We conducted disturbance experiments in two different parts of the species' range, in subarctic (Iceland) and in alpine (Italy) habitats.

Zoo Biology, EarlyView.We distributed a survey to global institutions housing bush dogs (Speothos venaticus) to collect data on factors which may affect litter survival. Information from the Zoological Information Management System (ZIMS) and studbook records supplemented this dataset. We found that within northern temperate regions, the number of pups reared to the age of 1

Integrative Zoology, EarlyView.We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Ecology and Evolution, 2023 Resource fluctuation is a major driver of animal movement, influencing strategic choices such as residency vs nomadism, or social dynamics. The Arctic tundra is characterized by strong seasonality: Resources are abundant during the short summers but ...
