Innate Immunity and Stress and Reproductive Hormone Metrics for Southern Beaufort Sea Polar Bears, 2013-2015

Data Download [28KB] | Metadata | AK Science Portal | Project Site | Date Range: 2013 - 2015

These were data collected from polar bears from the Southern Beaufort Sea during the spring between 2013 and 2015. Data include individual identification, demographic characteristics, year, status for the current and prior year regarding use of land, concentrations of stress response and reproductive hormones, blood-based biomarker measures indicative of fasting, body mass index, and body condition. These data were used to assess factors influencing variation in measures of innate immunity, physiological stress, and concentrations in stress-response and reproductive hormones in polar bears.
