Small mammals are important blood-meal hosts for the blacklegged tick, Ixodes scapularis, and reservoirs for the pathogens it transmits. Timber harvesting, a widespread forest management practice within I. scapularis's endemic range, may impact tick densities and infection prevalence via effects on rodent communities. We compared rodent population size, activity patterns, tick burdens, and tick-borne pathogen infection rates in forests under different timber harvesting regimes. We found that harvest intensity correlates negatively with rodent foraging intensity and positively with tick burdens. Thus, host behavior may mechanistically link forest structure to tick densities in managed forests.
小型哺乳动物是黑腿蜱(肩突硬蜱)重要的血餐宿主,也是该蜱传播病原体的宿主。木材采伐是肩突硬蜱分布范围内一种广泛的森林管理方式,可能通过对啮齿动物群落的影响来影响蜱的密度和感染率。我们比较了不同木材采伐方式下森林中啮齿动物的种群数量、活动模式、蜱负荷以及蜱传播病原体的感染率。我们发现采伐强度与啮齿动物觅食强度呈负相关,与蜱负荷呈正相关。因此,宿主行为可能在机制上把森林结构与人工林中的蜱密度联系起来。
