Analyzing the proximity to cover in a landscape of fear: A new approach applied to fine-scale habitat use by rabbits facing feral cat predation on Kerguelen archipelago
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-07)
Although proximity to cover has been routinely considered as an explanatory variable in studies investigating prey behavioral adjustments to predation pressure, the way it shapes risk perception still remains equivocal. This paradox arises from both the ambivalent nature of cover as potentially both obstructive and protective, making its impact on risk perception complex and context-dependent, and ...
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 ...
A probabilistic algorithm to process geolocation data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-18)
<p><i>Background: </i>The use of light level loggers (geolocators) to understand movements and distributions in terrestrial and marine vertebrates, particularly during the non-breeding period, has increased dramatically in recent years. However, inferring positions from light data is not straightforward, often relies on assumptions that are difficult to test, or includes an element of subjectivity ...
