摘要: Recent decline of sea ice habitat has coincided with increased use land by polar bears (Ursus maritimus) from the southern Beaufort Sea (SB), which may alter risks exposure to pathogens and contaminants. We assayed blood samples SB assess prior Brucella spp., Toxoplasma gondii, Coxiella burnetii, Francisella tularensis, Neospora caninum, estimate concentrations persistent organic pollutants (POPs), evaluate risk factors associated POPs. found that seroprevalence spp. T. gondii antibodies likely through time, provide first evidence C. N. F. tularensis. Additionally, odds were greater for used than remained on during summer fall, while mean POP chlordane (ΣCHL) lower land-based bears. Changes in bear behavior brought about climate-induced modifications Arctic marine ecosystem increase certain contaminant pathways.
