Harmonizing circumpolar monitoring of Arctic fox: benefits, opportunities, challenges and recommendations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity
monitoring plans to improve our ability to detect, understand and report on long-term
change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of
future monitoring because of its circumpolar distribution, ecological importance and reliance
on Arctic ecosystems. We provide ...
Homage to Hersteinsson and Macdonald: climate warming and resource subsidies cause red fox range expansion and Arctic fox decline
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
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, Hersteinsson
and Macdonald published a seminal paper hypothesizing that the northern distribution
limit of the red fox (Vulpes vulpes) is determined ...
Ecosystem drivers of an Arctic fox population at the western fringe of the Eurasian Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
The distribution of traditional breeding dens on the Varanger Peninsula (70–71°N) in northernmost
Fennoscandia indicates that this area once harboured a large Arctic fox population.
Early 20th century naturalists regarded the coastal tundra of the Fennoscandian Low Arctic to
be a stronghold for the species. At the start of our research in 2004, however, the local Arctic
fox population was ...
The importance of willow thickets for ptarmigan and hares in shrub tundra : the more the better?

Dietary variation in Icelandic arctic fox (Vulpes lagopus) over a period of 30 years assessed through stable isotopes
(Journal article; Tidsskriftartikkel, 2019-12-21)
Identifying resources driving long-term trends in predators is important to understand ecosystem changes and to manage populations in the context of conservation or control. The arctic fox population in Iceland has increased steadily over a period of 30 years, an increase that has been attributed to an overall increase in food abundance. We hypothesized that increasing populations of geese or seabirds ...
