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 ...
Toward understanding the effect of top predators on ecosystems
(Journal article; Tidsskriftartikkel, 2009)
To what extent top predators - carnivores at the top of food chains - drive or just respond to ecosystem dynamics is a central, but partially unresolved, question in ecology. In this report, we highlight how different research approaches employed in aquatic and terrestrial ecology may have a bearing on how the role of top predators in ecosystems is perceived.
