Temporal trend of mercury in relation to feeding habits and food availability in arctic foxes (Vulpes lagopus) from Svalbard, Norway
We investigated the temporal trend of mercury (Hg) in arctic foxes from Svalbard, Norway sampled in the period 1997–2014 ( n = 109, from 11 trapping seasons). We used linear models to investigate the effect of trapping season, feeding habits (δ 13 C), food availability from marine and terrestrial ec...
