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 ...
Emergent rainy winter warm spells may promote boreal predator expansion into the arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-06)
Climate change has been characterized as the most serious threat to Arctic biodiversity. In addition to gradual changes such as climate warming, extreme weather events, such as melting temperatures in winter and rain on snow, can have profound consequences for ecosystems. Rain-on-snow events lead to the formation of ice layers in the snow pack, which can restrict access to forage plants and cause ...
