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 ...

Food web approach for managing Arctic wildlife populations in an era of rapid environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-28)
Scientists and wildlife managers implementing adaptive monitoring and management schemes, are tasked with providing predictions of population responses to harvest and environmental changes. Such predictions are useful not only to forecast direct effects of climate, productivity, land use, or habitat degradation, but also changes in the food web, such as expanding/increasing species that are predators, ...
Effect of scavenging on predation in a food web
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-26)
<ol>
<li>The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and food-restricted environment, but contrary to predictions from the FEH, empirical evidence shows that Arctic mammals are often smaller than their temperate conspecifics. ...
Assessing the effect of predator control on an endangered goose population subjected to predator-mediated food web dynamics
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-29)
<ol>
<li>Assessing the effectiveness of conservation actions to halt population declines is challenging when confounded by other factors. We assessed whether culling of red fox, a predator currently increasing in number in the sub‐Arctic, contributed to recent recovery of the critically endangered Fennoscandian population of Lesser White‐fronted Goose <i>Anser erythropus</i>, while controlling for ...
Challenges and opportunities when implementing strategic foresight: lessons learned when engaging stakeholders in climate-ecological research
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-13)
Ecosystems are currently experiencing rapid changes. Decision-makers need to
anticipate future changes or challenges that will emerge in order to implement both short-term
actions and long-term strategies for reducing undesirable impacts. Strategic foresight has been
proposed to help resolve these challenges for better planning and decision-making in an uncertain future. This structured process ...
Life-cycle analysis of an endangered migratory goose to assess the impact ofconservation actions on population recovery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-29)
Evaluating the effectiveness of conservation actions is challenging for migratory species because a population can
be impacted anywhere along its route. Conservation actions for the critically endangered Fennoscandian lesser
white-fronted goose population include culling of red foxes in the breeding area and habitat improvements and
reduction of illegal hunting in the non-breeding areas. One goal ...
