My students and I have done a series of field experiments on the deer mouse (Peromyscus maniculatus), Townsend's vole (Microtus townsendii), and the creeping vole (Microtus oregoni) around Vancouver since 1971 to see what factors are important in causing populations to fluctuate. In 1973 we began work at Kluane Lake in the southwest Yukon to see if our findings could be extended to more northern populations.
