Rodents are reservoirs of various types of hantavirus, some of which are agents of hantavirus pulmonary syndrome in humans. Each hantavirus is associated with a single rodent host species but successive spill‐over events may eventually lead to host‐switching and new species’ becoming host of a given pathogen. This study aims to gain an understanding of the spatial ecology of two hantavirus‐host species, Akodon azarae, and Oligoryzomys flavescens, by identifying factors modulating their home range sizes and stability, and by evaluating intra‐ and interspecific spatial aggregation for these species and a third one—Oxymycterus rufus—living in sympatry. For this, eleven capture‐mark‐recapture surveys were carried out, spanning 22 months.

Pampean农业生态系统中的Akodon azarae和flavescens flavescens的家庭范围变异性，空间聚集和偏移。

啮齿动物是各种类型的汉坦病毒的宿主，其中有些是人类汉坦病毒肺综合征的病原体。每个汉坦病毒都与单个啮齿动物宿主物种相关，但是连续的溢出事件最终可能导致宿主转换，新物种成为给定病原体的宿主。这项研究旨在通过识别调节其宿主范围大小和稳定性的因素，并评估这些物种和物种的种内和种间空间聚集，从而了解两种汉坦病毒寄主物种Akodon azarae和flavescens flavescens的空间生态。第三个是生活在交sym中的Oxymycterus rufus。为此，进行了十一次为期22个月的俘获标记再捕获调查。
