An Arctic predator–prey system in flux: climate change impacts on coastal space use by polar bears and ringed seals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-17)
<p>1. Climate change is impacting different species at different rates, leading to alterations in biological interactions with ramifications for wider ecosystem functioning. Understanding these alterations can help improve predictive capacity and inform management efforts designed to mitigate against negative impacts.</p>
<p>2. We investigated how the movement and space use patterns of polar bears ...
Haul-out behaviour of Arctic ringed seals (Pusa hispida): inter-annual patterns and impacts of current environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-27)
Hauling out onto a solid substrate is an integral part of most pinnipeds’ activity budgets. Ringed seals (<i>Pusa hispida</i>) are an Arctic species that hauls out on sea ice routinely throughout the year. In 2006, a sudden change in the sea-ice regime occurred in Svalbard (Norway). Amongst other changes, the amount of land-fast ice declined sharply. This study examined the intra- and inter-annual ...
Haul-out behaviour of the world's northernmost population of harbour seals (Phoca vitulina) throughout the year

Contrasting changes in space use induced by climate change in two Arctic marine mammal species
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-06)
Global warming is inducing major environmental changes in the Arctic. These changes will differentially affect species owing to differences in climate sensitivity and behavioural plasticity. Arctic endemic marine mammals are expected to be impacted significantly by ongoing changes in their key habitats owing to their long life cycles and dependence on ice. Herein, unique biotelemetry datasets for ...
