At Bakers Hill, differential winter mortality of juvenile slowgrowing Amphibolurus ornatus is correlated with the incidence of frosts (Bradshaw, 1971). The present study shows that the probability an individual will spend the night in a refuge that is safe from the lethal effect of a frost is directly related to the individual's size. Thus should frosts occur during any particular winter, juvenile slow-growers, will suffer a higher mortality than juvenile fast-growers. At Tuttanning, animals do not segregate according to size, and consequently juvenile slow-growers do not suffer increased mortality during frosty winters.
在贝克山，幼年生长缓慢的饰纹须肢蜥的冬季死亡率差异与霜冻发生率相关（布拉德肖，1971年）。本研究表明，个体在免受霜冻致命影响的避难所过夜的概率与个体大小直接相关。因此，如果在任何特定冬季出现霜冻，幼年生长缓慢的个体将比幼年生长快速的个体遭受更高的死亡率。在塔坦宁，动物不会按大小进行区分，因此幼年生长缓慢的个体在霜冻冬季不会遭受更高的死亡率。
