Chukchi Sea Polar Bear Location Data 1985-1996 Chukchi Sea Polar Bear Location Data 1985-1996

These data are the raw location data collected from satellite radio-collars fitted on adult female polar bears in the Chukchi Sea, between 1985-1996. The collars were worn by adult female polar bears ranging within the Chukchi Sea subpopulation boundaries as identified by the International Union for the Conservation of Nature's Polar Bear Specialist Group. Agros collars were programmed...

Assessing the Robustness of Quantitative Fatty Acid Signature Analysis to Assumption Violations (Supplementary Data) Assessing the Robustness of Quantitative Fatty Acid Signature Analysis to Assumption Violations (Supplementary Data)

This dataset contains fatty acid (FA) data expressed as mass percent of total FA for bearded seals, ringed seals and walrus. This is one of many datasets used in Bromaghin et al. 2016 (https://doi.org/10.1111/2041-210X.12456). These supplemental data were used in computer simulations to compare the bias of several quantitative fatty acid signature analysis (QFASA) estimators and develop

Laysan Teal (Anas laysanensis) Microsatellite DNA Data, Laysan Island 1999-2009, Midway Atoll 2007-2010 Laysan Teal (Anas laysanensis) Microsatellite DNA Data, Laysan Island 1999-2009, Midway Atoll 2007-2010

The geographically closed, non-migratory populations of endangered Laysan Teal (Anas laysanensis) were sampled in the wild. This species was once widespread across the Hawaiian archipelago, but became isolated on Laysan Island (415 ha) from the mid-1800s until 2004 when a translocation to Midway Atoll (596 ha) was undertaken to reduce extinction risks. We compared genetic diversity and...

U.S. Geological Survey Polar Bear Mark-Recapture Records, Alaska Portion of the Southern Beaufort Sea, 2001-2010 U.S. Geological Survey Polar Bear Mark-Recapture Records, Alaska Portion of the Southern Beaufort Sea, 2001-2010

The dataset consists of one file of tabular data. These data include: a unique bear identification, bear sex, birth year, capture year, capture location (latitude and longitude), indicator of satellite radio status, and search effort.
