对生活在林地和芦苇床中的木鼠种群的密度、体质量、性别比、繁殖活动和家园大小的变化进行了研究。芦床种群：1.春季密度较低，2.体质量不同，初秋较低，3.栖息地大于林地种群。结果表明，食物可获得性和质量的差异强烈地影响了两个种群的行为；这些差异的主要影响是芦苇鼠以较低的体质量进入冬季，并遭受较高的冬季死亡率。芦苇栖息地较大的栖息地表明，生活在食物较差的栖息地的老鼠将通过巡逻比在丰富的栖息地更广泛的区域来提高它们的存活率。
Densities, variations in body mass, sex ratios, breeding activities and size of home-range were studied in wood mouse populations living in a woodland and a reed bed. In the reed bed population: 1. spring densities were lower, 2. body mass differed, and was lower in early autumn, and 3. home ranges were larger than in the woodland population. It is suggested that differences in food availability and quality strongly influenced the behaviour of the two populations; the main effect of these differences was that reed bed mice entered winter with a lower body mass and suffered higher winter mortality. The larger size of the home range in the reed bed suggests that mice living in a poor-food habitat will enhance their survival by patrolling a wider area than in a rich habitat
