| lemming winter habitat choice: a snow-fencing experiment. | the insulative value of early and deep winter snow is thought to enhance winter reproduction and survival by arctic lemmings (lemmus and dicrostonyx spp). this leads to the general hypothesis that landscapes with persistently low lemming population densities, or low amplitude population fluctuations, have a low proportion of the land base with deep snow. we experimentally tested a component of this hypothesis, that snow depth influences habitat choice, at three canadian arctic sites: bylot islan ... | 2012 | 22042523 |
