dc.description.abstractWe investigated the temporal trend of mercury (Hg) in arctic foxes from Svalbard, Norway sampled in the period 1997–2014 (<i>n</i> = 109, from 11 trapping seasons). We used linear models to investigate the effect of trapping season, feeding habits (δ<sup>13</sup>C), food availability from marine and terrestrial ecosystems (reindeer carcasses and sea ice cover), sex, age and body condition on liver total Hg (THg) levels. Liver THg levels increased in arctic foxes with 7.2% (95% CI: 2.3, 9.6) per year when the concentrations were adjusted for variation of δ<sup>13</sup>C, sea ice cover, and reindeer carcasses, whereas the raw annual trend was 3.5% (CI: −0.11, 7.2). However, the THg levels in arctic foxes from Svalbard are still lower than other marine mammals. We also demonstrate that arctic fox terrestrial food consumption is important for lowering the overall THg levels in this species.en_US
