Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 03:23 AM | Dataset Last Updated: January 13, 2025 at 12:00 AM
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.
