Statistical results from comparing prey percentages in diets of subadult and adult male and female polar bears sampled in the Chukchi Sea 2008–2017 that tested positive or negative for pathogen exposure using Mann-Whitney U-tests.

Dietary prey percentages are based on quantitative fatty acid analysis using data from polar bear and prey adipose tissue samples as reported in [79]. Sample sizes for each analysis are provided in parentheses within the pathogen column. P-values in bold with an asterisk highlight significant dietary percentages between bears exposed versus not exposed to a pathogen.
