Anurans that hibernate at or near the ground surface can survive prolonged exposure to low winter temperatures of northern latitudes by tolerance to freezing. An accumulation of glycerol during winter was correlated with frost tolerance, indicating that this compound is associated with natural tolerance to freezing in a vertebrate.
在地面或接近地面处冬眠的无尾目动物能够通过耐受冻结来在北纬地区漫长的冬季低温环境中存活。冬季甘油的积累与抗冻能力相关，这表明这种化合物与脊椎动物对冻结的天然耐受性有关。
