  • A novel mark-recapture-recovery survey using genetic sampling for polar bears Ursus maritimus in Baffin Bay 
    Atkinson, Stephen; Laidre, Kristin L.; Arnold, Todd W.; Stapleton, Seth; Regehr, Eric V.; Born, Erik W.; Wiig, Øystein; Dyck, Markus; Lunn, Nicholas J.; Stern, Harry; Paetkau, David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Changes in sea-ice dynamics are affecting polar bears Ursus maritimus across their circumpolar range, which highlights the importance of periodic demographic assessments to inform management and conservation. We used genetic ...
  • An on-ice aerial survey of the Kane Basin polar bear (Ursus maritimus) subpopulation 
    Wiig, Øystein; Atkinson, Stephen N.; Born, Erik W; Stapleton, Seth; Arnold, Todd; Dyck, Markus; Laidre, Kristin L.; Lunn, Nicholas J.; Regehr, Eric V. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract There is an imminent need to collect information on distribution and abundance of polar bears ( Ursus maritimus ) to understand how they are affected by the ongoing decrease in Arctic sea ice. The Kane Basin (KB) ...
  • Changes in winter and spring resource selection by polar bears Ursus maritimus in Baffin Bay over two decades of sea-ice loss 
    Laidre, Kristin L.; Stern, Harry; Born, Erik W.; Heagerty, Patrick; Atkinson, Stephen; Wiig, Øystein; Lunn, Nicholas J.; Regehr, Eric V.; McGovern, Richard; Dyck, Markus (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Loss of Arctic sea ice has implications for the distribution and population structure of ice-dependent species such as polar bears Ursus maritimus. We used remotely sensed sea-ice concentration data for Baffin Bay, Canada, ...
  • Performance and retention of lightweight satellite radio tags applied to the ears of polar bears (Ursus maritimus) 
    Wiig, Øystein; Born, Erik W; Laidre, Kristin L; Dietz, Rune; Jensen, Mikkel V; Durner, George M; Pagano, Anthony M; Regehr, Eric; St. Martin, Michelle; Atkinson, Stephen; Dyck, Markus (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Background Satellite telemetry studies provide information that is critical to the conservation and management of species affected by ecological change. Here we report on the performance and retention of ...
  • Range contraction and increasing isolation of a polar bear subpopulation in an era of sea ice loss 
    Laidre, K.L.; Born, Erik W.; Atkinson, Stephen N.; Wiig, Øystein; Andersen, Liselotte W.; Lunn, Nicholas J.; Dyck, Markus; Regehr, E.V.; McGovern, R.; Heagerty, Patrick; Heagerty, P. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased ...
  • The role of satellite telemetry data in 21st century conservation of polar bears (Ursus maritimus). 
    Laidre, Kristin L.; Durner, George M.; Lunn, Nicholas J.; Regehr, Eric V.; Atwood, Todd C.; Rode, Karyn D.; Aars, Jon; Routti, Heli; Wiig, Øystein; Dyck, Markus; Richardson, Evan S.; Atkinson, Stephen; Belikov, Stanislav; Stirling, Ian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Satellite telemetry (ST) has played a critical role in the management and conservation of polar bears (Ursus maritimus) over the last 50 years. ST data provide biological information relevant to subpopulation delineation, ...
