Kodiak Brown Bears:  Results

THE STUDY

RESEARCHERS

RESULTS

PUBLICATIONS

Since 2017 we have captured and attached GPS radio collars to 79 brown bears, obtaining over 600,000 locations. We attached an accelerometer to each collar to examine movement behavior and estimate energetic costs. During captures we weigh bears, record morphometric measurements, and collect tissue samples.

We also use stable isotope analyses on hair collected from brown bears across the Kodiak Archipelago. Analyses requires use of mass spectrometry, which separates different isotopes to estimate of terrestrial and aquatic diet components based on mass to change ratios.
