Effects of food and predators on the home-range sizes of arctic ground squirrels (Spermophilus parryii)
We used radiotelemetry to study the effects of food addition and predator reduction on the home-range sizes of adult arctic ground squirrels (Spermophilus parryii) on large-scale experimental grids in the boreal forest of the southwestern Yukon Territory. Home ranges were 2-7 times smaller on food-s...
