Adjustments of the Northwestern muskrat (ondatra zibethicus spatulatus) to a Northern environment ...
The northwestern muskrat (Ondatra zibethicus spatulatus) is nowhere more abundant than in the delta of the Mackenzie River in northern Canada. An investigation was undertaken to assess the adjustments resident animals have made in order to inhabit a region more than one hundred miles inside the Arct...

The northwestern muskrat (Ondatra zibethicus spatulatus) is nowhere more abundant than in the delta of the Mackenzie River in northern Canada.
