A tale of two polar bear populations: ice habitat, harvest, and body condition (2011, background): “Polar bears were captured in DS and BB as part of ongoing efforts to monitor the status of the two populations (Stirling and Kiliian 1980; Stirling et al. 1980; Taylor et al. 2001, 2005; Peacock 2009; Canadian Wildlife Service, unpublished data; Greenland Institute of Natural Resources, unpublished…”
Impacts of changing sea-ice conditions on Arctic marine mammals (2011, background): “…up and delayed freeze-up had resulted in a shorter sea-ice-season in the region which caused the bears to spend more time ashore, resulting in declining body condition, reproductive rates, survival, and population size (Stirling et al. 1999, 2004; Parks et al. 2006; Stirling and Parkinson 2006).”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “…areas (i.e., Hudson Bay, Foxe Basin, Baffin Bay/Davis Strait), the annual ice melts completely and all bears are forced to spend up to several months on land fasting until freeze-up allows them to return to the ice again (e.g., Stirling et al. 1999, Taylor et al. 2001, Stirling and Parkinson 2006).”
Predicting survival, reproduction and abundance of polar bears under climate change. (2010, unknown): “For illustration we discuss survival predictions for a fasting period length of 120 days, typical of the 1980s, and 180 days which reflects potential future conditions (the fasting period has been increasing by about 7 days per decade since the early 1980s; Stirling and Parkinson, 2006).”
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): “September, we predicted that the number of polar bears occurring on land would increase as opportunities for bears to return to the sea ice decline ( Stirling et al. 1999; Stirling and Parkinson 2006).”
Trends in body condition in polar bears (Ursus maritimus) from the Southern Hudson Bay subpopulation in relation to changes in sea ice (2016, background): “However, the duration of sea ice has declined across much of polar bear range (Stirling and Parkinson 2006), especially in seasonal sea ice regions (Amstrup et al.”
Impacts of climate change on the seasonal distribution of migratory caribou (2009, background): “…regulates many processes across numerous taxa, increases in air temperature will impact many species, including the abundance of polar bears (Ursus maritimus, Stirling & Parkinson, 2006) and the distribution of freshwater fishes, such as smallmouth bass (Micropterus dolomieu, Sharma et al., 2007).”
Changes in Canadian seabird populations and ecology since 1970 in relation to changes in oceanography and food webs (2009, background): “Arctic cod is an ice-associated fish (Bradstreet and Cross 1982) and these changes may be linked to progressively earlier break-up of sea-ice in Hudson Bay since the early 1990s (Gagnon and Gough 2005; Stirling and Parkinson 2006).”
POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, background): “We are particularly grateful to the native hunters of Nunavut and Newfoundland and Labrador for collecting fat samples from marine mammals harvested in their subsistence hunts.”
Rapid ecosystem change and polar bear conservation (2013, background): “As sea ice availability has declined, forcing bears onshore for progressively longer periods, the number of human-bear interactions has increased (Stirling & Parkinson 2006; Towns et al. 2009).”
Spatial and temporal patterns of problem polar bears in Churchill, Manitoba (2009, background): “Since the early 1980s, the condition of adult bears and average weights of lone adult females in the fall have declined resulting in increased nutritional stress (Derocher and Stirling 1995a; Stirling and Lunn 1997; Stirling and Parkinson 2006).”
