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 ...
Modeling the demography of species providing extended parental care: A capture–recapture multievent model with a case study on polar bears (Ursus maritimus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-10)
<ol>
<li>In species providing extended parental care, one or both parents care for altricial young over a period including more than one breeding season. We expect large parental investment and long-term dependency within family units to cause high variability in life trajectories among individuals with complex consequences at the population level. So far, models for estimating demographic ...
Using camera traps to monitor cyclic vole populations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-02)
Camera traps have become popular labor-efficient and non-invasive tools to study animal populations. The use of camera trap methods has largely focused on large animals and/or animals with identifiable features, with less attention being paid to small mammals, including rodents. Here we investigate the suitability of camera-trap-based abundance indices to monitor population dynamics in two species ...
