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 ...
Not only mosses: lemming winter diets as described by DNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-01)
The temporal dynamics of most tundra food webs are shaped by the cyclic population
dynamics of lemmings. While processes during winter may be behind the recent disruptions
of lemming cycles, lemming winter ecology is poorly known. We present here the first DNA metabarcoding data on the winter diet of Norwegian lemmings (Lemmus lemmus), based on feces collected after a winter of population ...
