Caribou may be indirectly affected by sea-ice loss in the Arctic

Melting sea ice in the Arctic may be leading, indirectly, to fewer caribou calf births and higher calf mortality in Greenland, according to scientists at Penn State University. Eric Post, a Penn State University professor of biology, and Jeffrey Kerby, a Penn State graduate student, have linked the melting of Arctic sea ice with changes in the timing of plant growth on land, which in turn is associated with lower production of calves by caribou in the area. The results of the study will be published in the journal Nature Communications on 1 October 2013.
