• Population ecology of polar bears at Svalbard, Norway (2005, methodology): “Axillary girth (cm) was measured as the circumference around the chest at the axilla with a rope tightened with a tension of about 0.5 kg. Body mass was estimated from a regression model developed for the study population using axillary girth and body length (Derocher and Wiig 2002).”
• Potential causes and life-history consequences of sexual size dimorphism in mammals (2005, background): “For example, in the polar bear (Ursus maritimus; Derocher & Wiig, 2002 ), a longer period of growth in males was found to result in pronounced sexual dimorphism in both body length and mass.”
• POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, background): “Adult male polar bears are roughly twice the size of adult females (Derocher et al. 2005) and individuals of both sexes continue to grow after reaching sexual maturity (Derocher and Wiig 2002).”
• Sexual dimorphism and the mating ecology of polar bears (Ursus maritimus) at Svalbard (2010, methodology): “The mean age of paired males in our study (13.6 years) was similar to the age at which adult males achieve 97% of their asymptotic body mass (13.5 years; Derocher and Wiig 2002).”
• The prevalence of Toxoplasma gondii in polar bears and their marine mammal prey: evidence for a marine transmission pathway? (2010, background): “By the age of ten, male polar bears are more than twice as heavy as their female counterparts (Derocher and Wiig 2002), and this almost certainly has an impact on the size of prey they take.”
• A tale of two polar bear populations: ice habitat, harvest, and body condition (2011, methodology): “We therefore chose to apply the modified von Bertalanffy length curve, which has been found to be the best fit for polar bears in other studies (Derocher and Wiig 2002).”
• Brown bear conservation and the ghost of persecution past (2011, background): “…on life-history parameters have been found repeatedly in ungulates (e.g. Albon et al., 1987; Skogland, 1989; Post et al., 1997; Festa-Bianchet et al., 2000) as well as in large carnivores (e.g. Dahle et al., 2006; Derocher and Stirling, 1995; Derocher and Wiig, 2002; Zedrosser et al., 2006).”
