【 摘 要 】

ABSTRACTThe Arctic fox (Vulpes lagopus) is a small canid with a circumpolar Arctic distribution. Several subspecies are recognized, including a subspecies known as the Pribilof fox (V. l. pribilofensis) endemic to the Pribilof Islands of Alaska, USA. Pribilof fox tissues were collected from the islands of St. Paul (n = 38) and St. George (n = 13). Levels of persistent organic pollutants (POPs) and stable isotopes of carbon and nitrogen were measured and the findings related to sex, age class, island and access to anthropogenic food resources using ANOVA and principal component analysis. The rank order for POPs in fat was polychlorinated biphenyls (∑PCBs) > chlordanes (∑CHLs) ≫ hexachlorocyclohexanes (∑HCHs) > DDTs (∑DDTs) > hexachlorobenzene (HCB) ~ polybrominated diphenyl ethers (∑PBDEs). Adult females had lower mean levels of most POPs (∑PCBs, ∑CHLs, ∑HCHs, ∑DDTs) and lower δ15N values than adult males. Foxes on St. Paul had significantly higher levels of most POPs than those on St. George, though St. G...
