These data represent estimates of den entrance and exit dates for female polar bears in the southern Beaufort and Chukchi Seas based on temperature sensor data obtained from satellite collars. An algorithm described in Olson et al. (2017) was used to determine whether the female entered a den and further analyses using temperature data as described in Olson et al. (2017) were used to assess den entry and emergence dates. The algorithm used identified the denning period as that during which collar temperature remained consistently above a temperature threshold. As such, users of these data should be aware that bear behavior can affect den entrance and exit date. If a bear moves in and out of a den frequently, the...
These data are the data for spring body composition and energy content for adult female brown bears from Gates of the Arctic, Lake Clark, Kodiak, and Katmai, Alaska, 2014-2017.
This dataset contains a select subset of Argos and GPS locations collected by satellite data collection systems from collared adult female polar bears that were instrumented in the southern Beaufort Sea between 1985-2015.
This dataset is one table with time-linked behavior data derived from video camera collars on polar bears on land near Churchill, Manitoba, Canada. Eighteen polar bears were equipped with video-camera collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) for 19 - 23 days in 2019, 2021, and 2022.
These data are the data for age, skull size, body length, and lean mass for Gates of the Arctic, Lake Clark, Kodiak, and Katmai, Alaska, 2013-2016.
