Specimens were once found in England, but they are now extirpated. For the most part, lemmings of the genus Lemmus can co-exist with those in the Dicrostonyx genus. Arctic Lemmings are known to migrate when population density becomes too great and they will resort to swimming while in search of a new habitat. The disappearance of lemmings and the lemming cycles in the Arctic have shown that they are the causes of fluctuations in local breeding between geese and waders. Recovery of Lemmings after years of low density is associated with a period of successful breeding and maintenance of their young in the snow. The diet of the Arctic Lemming has been studied and it has been found that their diet primarily consists of 86% dicotyledons, 14% monocotyledons, 1<%mosses. The diet of a family of lemmings would be mostly Saliceae. Poaceae is also in their diet. They are a well studied example of a cyclic predator prey relationship. Terns in the Arctic would target lemmings that would move in groups and they would use their bills to attack lemmings and, after the attack, lemmings would either seek shelter in a hole or somewhere that was out of the tern's territory in order to avoid another attack. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arctic lemming」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
