In order to determine the habitat preferred by Myodes (before Clethrionomys) glareolus and the corresponding Puumala hantavirus seroprevalence in those habitats, we captured rodents simultaneously in three significantly different habitats. We compared trapping success and presence of virus per habitat during an ongoing epidemic in order to test the hypothesis of a density-dependent seroprevalence. Our study showed that bank vole population density, as well as Puumala virus seroprevalence, were habitat dependent. Apodemus sylvaticus was found more vulnerable for deteriorating habitat conditions than M. glareolus and could play a role as vehicle for Puumala virus and as mediator for inter- and conspecific virus transmission.
为了确定林姬鼠（棕背䶄属之前）偏好的栖息地以及这些栖息地中相应的普马拉汉坦病毒血清阳性率，我们在三种显著不同的栖息地同时捕获啮齿动物。在疫情持续期间，我们比较了每个栖息地的捕获成功率和病毒存在情况，以检验血清阳性率与密度相关这一假设。我们的研究表明，棕背田鼠种群密度以及普马拉病毒血清阳性率均依赖于栖息地。与林姬鼠相比，发现森林姬鼠更容易受到栖息地条件恶化的影响，并且它可能充当普马拉病毒的载体以及种间和种内病毒传播的媒介。
