美国的森林破坏和破碎化最近已被证明会减少哺乳动物的物种多样性，并提高白足鼠（Peromyscus leucopus）的种群密度。物种多样性减少和小片段中小鼠密度高的一个潜在后果是人类暴露于莱姆病的增加。由于白足鼠是莱姆病细菌伯氏疏螺旋体的主要天然宿主，因此预计接触这种疾病的风险会增加。以小鼠为食的黑腿蜱（肩突硬蜱）比以任何其他宿主物种为食的蜱更有可能感染这种细菌。我们假设小的森林斑块（
Forest destruction and fragmentation in the United States recently have been shown to reduce mammalian species diversity and to elevate population densities of white-footed mice ( Peromyscus leucopus ). One potential consequence of reduced species diversity and high mouse density in small fragments is an increase in human exposure to Lyme disease. Increased risk of exposure to this disease is expected because of the role of the white-footed mouse as the principal natural reservoir of the Lyme bacterium, Borrelia burgdorferi . Blacklegged ticks ( Ixodes scapularis ) feeding on mice have a higher probability of becoming infected with the bacterium than do ticks feeding on any other host species. We hypothesized that small forest patches (
