Microhabitat utilisation, home ranges, and movement patterns of the collared lemming ( Dicrostonyx groenlandicus) in the central Canadian Arctic
We investigated patterns of home ranges, movements, and microhabitat use of the collared lemming (Dicrostonyx groenlandicus) on Kent Peninsula, Northwest Territories. Eleven animals were fitted with radio collars and intensively radio-tracked for 2 months. Males and females differed in their home ra...

We investigated patterns of home ranges, movements, and microhabitat use of the collared lemming (Dicrostonyx groenlandicus) on Kent Peninsula, Northwest Territories.
