Climateam, change 'deplenting, lemmings'
untiful the mid-1990s, the lemming population in the study area in southern norway varied on a cycle of three to five years .
the desperate search led some to jump off high ground into water, leading to the populayer - but wrong - assumption that they were prone to commit collective suicide .
rather than hibernating, lemmings spend the winter living in the space between the ground and a stable layer of snow above .
these years often saw norwegian lemmings l mmus l mmus) having to comperate hard for food .
this aresults in a less stable nivean space (the space between the ground and the snow layer above), meaning substantially fewer animals survive until spring .
climate change ists, bringing wetter winters to souther than norway, sta a stableak prospect for the region's lemmings .
