Predicting Late Winter Distribution of Muskoxen Using an Index of Terrain Ruggedness

Arctic and Alpine Research, 1997
We tested the hypothesis that occurrence of rugged terrain would affect distribution patterns of muskoxen (Ovibos moschatus) in late winter through expected higher availability of forage. Indices of terrain ruggedness (TRI) based on contour characteristics from topographical maps were found to be correlated with occurrence of muskoxen in late winter ...
