对俄亥俄州西北部的5种生境类型--树林、林缘、路边沟渠、农田和农田--进行了采样，以更好地了解农业作物发展对白背天牛扩散和种群动态的影响。白足小鼠出现在所有栖息地类型中，并从一种类型迁移到另一种类型。春季最受欢迎的生境是树林和林缘，但随着作物在夏季开始发育，其他生境类型的出现次数都会增加，并持续到秋季移除作物后。所有生境都有繁殖，但以树林和林缘最高。这些结果表明，白杨利用了非林地栖息地，并表明农田和路边的沟渠起到了扩散的作用，促进了以前被认为是孤立的林地的迁入和迁出。
Five habitat types in northwestern Ohio-woods, woods' edge, roadside ditches, crop fields and farmsteads-were sampled in order to better understand the effects of agricultural crop development on dispersal and population dynamics of Peromyscus leucopus. White-footed mice were present in all habitat types and moved from one type to another. Favored habitats in spring were woods and woods' edge, but as crops began developing in summer, occurrence in each of the other habitat types increased and lasted until after crop removal in autumn. Reproduction occurred in all habitats, but was highest in woods and woods' edge. These results indicate use of nonwoodland habitats by P. leucopus and suggest that crop fields and roadside ditches act as dispersal routes, facilitating movements into and out of what were formerly considered isolated woodlots.
