Variation in winter diet of southern Beaufort Sea polar bears inferred from stable isotope analysis (2007, unknown): “There appears to be two groups of polar bears near Svalbard (Mauritzen et al. 2001).”
Importance of fast ice and glacier fronts for female polar bears and their cubs during spring in Svalbard, Norway (2012, unknown): “Polar bears from the Svalbard/Barents Sea population show a high degree of seasonal fidelity (Mauritzen et al. 2001); site fidelity has also been observed in other polar bear populations (Stirling et al. 1977, 1980, 2004, Lentfer 1983, Bethke et al. 1996, Born et al. 1997, Taylor et al. 2001,…”
Low site fidelity and home range drift in a wide-ranging, large Arctic omnivore (2009, background): “If an animal shows fidelity to seasonal ranges, observations 12 months apart will be closer together than expected ( Mauritzen et al. 2001 ).”
A novel method for identifying behavioural changes in animal movement data. (2009, background): “Many fundamental demographic parameters can be directly related to animal movements, including foraging success, breeding success, migration and dispersal (Guinet et al. 2001; Mauritzen et al. 2001; Laidre et al. 2003; Matthiopoulos 2003; Buskirk & Millspaugh 2006).”
Population ecology of polar bears at Svalbard, Norway (2005, background): “Polar bears in Svalbard are part of the Barents Sea population and are linked genetically and through movements to the bears in the western Russian Arctic (Wiig 1995; Paetkau et al. 1999; Mauritzen et al. 2001).”
Seasonal and annual movement patterns of polar bears on the sea ice of Hudson Bay (2006, unknown): “For example, females have greater energetic demands when they are accompanied by dependent offspring than when they are not, and therefore may adopt different space-use strategies (Amstrup et al. 2000; Mauritzen et al. 2001 ).”
Optimal use of resources structures home ranges and spatial distribution of black bears (2007, background): “Energetic costs of lactation are high (Moen & Boomer 2005), so intuitively, the resource threshold by which a lactating female chooses patches for a home range should be higher than when she is not lactating (e.g. Mauritzen et al. 2001).”
Using satellite telemetry to define spatial population structure in polar bears in the Norwegian and western Russian Arctic (2002, background): “However, in the Svalbard and Barents Sea area spatial distribution of female polar bears was similar for females in the different reproductive states ( Mauritzen, Derocher & Wiig 2001 ) and we therefore expected little influence of reproductive state on spatial population structure.”
Diet composition of polar bears in Svalbard and the western Barents Sea (2002, unknown): “and dietary differences were postulated to explain the different space use patterns (Mauritzen et al. 2001).”
The importance of tidewater glaciers for marine mammals and seabirds in Svalbard, Norway (2014, background): “Satellite tracking of female polar bears later in the year shows that they generally display two different space-use strategies; one is to stay close to the coast and the other is to go offshore onto the drifting ice when the sea-ice recedes during summer (Mauritzen et al., 2001).”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “They demonstrate long-term fidelity to denning and spring feeding areas and are faithful to denning substrate (i.e., land vs. ice; Ramsay and Stirling 1990, Amstrup and Gardner 1994, Wiig 1995, Mauritzen et al. 2001).”
