Evaluating Competition Between Sympatric Flying Squirrels (Glaucomys Spp.) In Northeastern Minnesota
… species with similar niches. Northern flying squirrels (Glaucomys sabrinus) and southern flying squirrels (G. volans) have increasingly overlapping ranges due to warming temperatures across eastern North America, including northern Minnesota. We evaluated whether the two species spatially …

Effects of tannins on protein digestibility and detoxification activity in gray squirrels (Sciurus carolinensis)
Captive gray squirrels were fed acorns or diets containing commercial tannins to determine the effects of tannins on digestion and detoxification (glucuronidation) activity. In the Acorn experiment, Northern red oak acorns (Quercus rubra), white oak acorns (Q. alba), or rat chow were fed to …
