A tracking technique to locate small mammals at low densities
To optimize our livetrapping of low-density populations of lemmings (Dicrostonyx kilangmiutak) and voles (Microtus oeconomus) (0.2-0.4 animals/ha) in the Arctic tundra, we developed a powdered-slide tracking technique to determine if burrows were occupied. Painted microscope slides covered with talc...
