Observations on a Cyclic Decline of Lemmings (Lemmus) on the Arctic Coast of Alaska During the Spring of 1949
Results of observations carried out at the Arctic Research Laboratory, Point Barrow region (1) "during the peak density" preceding the cyclic decline occurring in the spring of 1949, (2) during the decline, and (3) for more than a year subsequent to it. The conclusions (a) relate the four-...
