Our scientists just published a paper in the Journal of Mammalogy (Rodent populations on the northern Great Plains respond to weather variation at a landscape scale). Using tens of thousands of mice and voles found within owl pellets, this paper describes the effects of weather on population changes of southern Saskatchewan’s most common rodents. Interestingly, they found meadow vole populations increase 5-times above normal following winters with deep snow cover. Yep, snowy winters tend to produce excellent vole-crops!
