Dispersal of juvenile collared lemmings (Dicrostonyx groenlandicus) in a high-density population
We tested whether dispersal of juvenile lemmings occurs at high population densities and whether predation risk affects movements of juveniles. The study was conducted in July and August 1996 on the Kent Peninsula, Northwest Territories, during a peak in the lemming cycle. We fitted 43 juvenile collared lemmings (Dicrostonyx groenlandicus) of the summer generations on a control plot and a predator-exclosure plot with radio transmitters and examined their home ranges and movement patterns.

Dicrostonyx: Collared Lemmings, or Varying Lemmings
These lemmings are short, stockily built creatures. The third and fourth claws of their forefeet are unusually large and well adapted to digging. In summer these claws are about normal in appearance, but with the approach of winter they develop a peculiar double effect in a vertical plane, which makes them very strong and well suited for burrowing in the frozen earth or in snow and ice. This remarkable development of the third and fourth claws in winter distinguishes Dicrostonyx from all other small rodents. [eng] |
