Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-30)
Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation where food availability is anticipated to be low, and thus reduced diet overlap is expected. We present here the first assessment of diet overlap of high arctic lemmings during winter based on DNA ...
Sources of variation in small rodent trophic niche: New insights from DNA metabarcoding and stable isotope analysis

Stakeholder Perspectives on Triage in Wildlife Monitoring in a Rapidly Changing Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-15)
Monitoring activities provide a core contribution to wildlife conservation in the Arctic. Effective monitoring which allows changes in population status to be detected early provides opportunities to mitigate pressures driving declines. Monitoring triage involves decisions about how and where to prioritize activities in species and ecosystem based monitoring. In particular, monitoring triage examines ...
Effects of changing permafrost and snow conditions on tundra wildlife: critical places and times
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-21)
The change of water phase around 0 °C has considerable impacts on wildlife ecology because liquid and solid water strongly differ in their insulating capability, mechanical resistance, and light reflectance. Freeze and melt events thus have strong ecological relevance, particularly in the Arctic where snow and ice are omnipresent and their conditions are changing due to climate warming. We first ...
