Age-specific survival, abundance, and immigration rates of a Weddell seal (Leptonychotes weddellii) population in McMurdo Sound, Antarctica (2004, background): “Such results are not unusual considering that Gaillard et al. (1993) found that juveniles are often more susceptible to changes in the environment than adults.”
Ultrasonic tracking of Greenland sharks, Somniosus microcephalus, under Arctic ice (2004, background): “In some respects these movements would be analogous to the inter-island movements of white sharks noted by Strong et al. (1992) and to the movements of polar bears searching for ringed seals in areas of land-fast sea ice (Gjertz and Lydersen 1986; Furgal et al. 1996; Ferguson et al. 1999, 2000).”
Seasonal and annual movement patterns of polar bears on the sea ice of Hudson Bay (2006, unknown): “In addition, seasonal changes in ice conditions create different habitats through which bears must move and hunt, and their movement rates and habitat preferences often change cyclically with the seasons (Ferguson et al. 2000a).”
Forecasting the relative influence of environmental and anthropogenic stressors on polar bears (2016, background): “Two of the ecoregions—the Polar Basin Convergent Ice (Convergent; three subpopulations) and Archipelago (six subpopulations)—are characterized by persistent multiyear sea ice that has allowed polar bears to remain on the ice yearround (e.g., Ferguson et al. 2000).”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “…may seek shelter in temporary dens in drifted snow on the ice at high latitudes for up to several weeks at a time to escape periods of intense cold or inclement weather or when seals may be less abundant or accessible (Messier et al. 1994, Ferguson et al. 2000a, b, Van de Velde et al. 2003).”
Sexual dimorphism and the mating ecology of polar bears (Ursus maritimus) at Svalbard (2010, background): “Because polar bears have large home ranges, are distributed at low densities, live in remote areas, and live in a highly dynamic sea ice habitat (Ferguson et al. 2000; Mauritzen et al. 2003), their mating system is poorly understood.”
Effects of sea ice extent and food availability on spatial and temporal distribution of polar bears during the fall open-water period in the Southern Beaufort Sea (2008, background): “…and BaYn Bay, includes spending up to 4 months of the year on land during the fall open-water period (Stirling et al. 1977; Derocher et al. 1993; Ferguson et al. 1997, 2000), polar bears in Alaskan populations, including the Southern Beaufort Sea (SBS) and Chukchi Sea, and other open basin…”
Long-distance swimming by polar bears (Ursus maritimus) of the southern Beaufort Sea during years of extensive open water (2012, background): “Polar bears are essentially a terrestrial mammal that filled a niche on the top surface of an ice-covered ocean (Ferguson et al. 2000; Amstrup 2003; Mauritzen et al. 2003a; Durner et al. 2004).”
Segregation of Beaufort Sea beluga whales during the open-water season (2006, unknown): “This method has been successfully used to evaluate habitat use at the seasonal scale in polar bears (Ursus maritimus Phipps, 1774) (Ferguson et al. 2000) as well as at the finer scale of daily habitat selection in woodland caribou (Rangifer tarandus caribou (Gmelin, 1788)) (Rettie and Messier 2000).”
Observations of mortality associated with extended open-water swimming by polar bears in the Alaskan Beaufort Sea (2006, background): “Ferguson et al. (2000) documented only 0.04% (3 of 6,943) of polar bear telemetry observations were classified as occurring in ‘‘open water’’.”
