Under its fur, the arctic fox has a lot of body fat, which helps to keep it insulated in the cold. In the autumn, arctic foxes increase their fat reserves to provide energy and insulation through the winter. The Arctic fox in its winter coat. The arctic fox’s compact, round shape an...
Some of the arctic hare’s predators include the arctic fox, the red fox, the gray wolf, the ermine, snowy owls, and the Canada lynx.Humans are also traditional predators of this animal. Many people who live in the Arctic hare’s territory depend on hunting them for food and for their...

Atmospheric mercury (Hg(0), Hg(II)) and riverine exported Hg (Hg(II)) are proposed as important Hg sources to the Arctic Ocean. As plankton cannot passively uptake Hg(0), gaseous Hg(0) has to be oxidized to be bioavailable. Here, we measured Hg isotope r

A major goal in evolutionary biology is to understand the processes underlying phenotypic variation in nature. Commonly, studies have focused on large interconnected populations or populations found along strong environmental gradients. However, studies
Animals seen so far: Lynx, Fox, Wolves, Coyote, Caribou, Moose, Bison, Willow Ptarmigan, Ravens. Standing on a Frozen Ocean Tuktoyaktuk is filled with history and adventure. People die all the time up here, when a whiteout causes them to get lost, or their snowmobile breaks through the ...

We also assumed a porosity of 0.20 for the sandstone (below 24 m depth) based on the values reported for sandstone of the Colville Group on the Umiat region on the North Slope of Alaska (Fox et al., 1979). Because the unconsolidated sediments (between 3 and 24 m depth) are formed ...
