Lemmings do migrate, and in vast numbers sometimes, but notion of a deliberate march into the sea is false. According to genetic research, [ 5 ] the Norwegian lemming survived the Pleistocene glaciation in western Europe, inhabiting various refugia which were not covered by ice.
Lemmings are quite rounded in shape, with brown and black, long, soft fur. They have a very short tail, a stubby, hairy snout, short legs and small ears. They have a flattened claw on the first digit of their front feet, which helps them to dig in the snow. They are herbivorous, feeding mostly on mosses and grasses.

During winter brown lemmings live in insulated burrows in the ground made out of sedges and grasses (Reid et al. 2011).
According to NOAA, "while the map shows the climatological probability of snow-covered ground on December 25, the actual conditions this year may vary widely from these probabilities because the ...
The map of Biogeographical Regions therefore had to be expanded to cover all of Europe, not just the European Union. [7] Five more biogeographical regions were added: Anatolian, Arctic, Black Sea, Pannonian and Steppic. The revised Biogeographical Regions map for the Pan-European area was approved by the Standing Committee of the Bern ...
The pyrenees have a lot of small glaciers that have stopped moving or haven't been studied since becoming very small. For example, in the Monte Perdido masif there were many more glaciers, like the Grieta, the La cascade, the Marboré, the Paillas (two glaciers), and the Astazou.
