During the 20th century, there has been an ongoing agricultural expansion and global warming, two of the main determinants influencing biodiversity changes in Argentina. The red hocicudo mouse (Oxymycterus rufus) inhabits subtropical grasslands and riparian habitats and has increased its abundance in recent years in central Argentina agroecosystems. This paper describes the long-term temporal changes in O. rufus abundance in Exaltación de la Cruz department, Buenos Aires province, Argentina, in relation to weather fluctuations and landscape features, as well as analyzes the spatio-temporal structure of captures of animals. We used generalized liner models, semivariograms, the Mantel test, and autocorrelation functions for the analysis of rodent data obtained from trappings conducted between 1984 and 2014. O. rufus showed an increase in abundance across the years of study, with its distribution depending on landscape features, such as habitat types and the distance to floodplains. Capture rates showed a spatio-temporal aggregation, suggesting expansion from previously occupied sites. O. rufus was more abundant at lower minimum temperatures in summer, higher precipitation in spring and summer, and lower precipitations in winter. Weather conditions affected O. rufus abundance, but there was local variation that differed from global patterns of climate change.

潘帕斯农业生态系统中红花鼠（Oxymycterus rufus）丰度长期变化的环境驱动因素

20 世纪，农业持续扩张和全球变暖是影响阿根廷生物多样性变化的两个主要决定因素。红花鼠（ Oxymycterus rufus ）栖息于亚热带草原和河岸栖息地，近年来在阿根廷中部农业生态系统中的数量有所增加。本文描述了阿根廷布宜诺斯艾利斯省 Exaltación de la Cruz 省O. rufus丰度随天气波动和景观特征的长期时间变化，并分析了动物捕获的时空结构。我们使用广义线性模型、半变异函数、Mantel 检验和自相关函数来分析从 1984 年至 2014 年期间进行的诱捕中获得的啮齿动物数据。在研究期间， O. rufus 的丰度有所增加，其分布取决于景观特征，例如栖息地类型和距洪泛区的距离。捕获率显示出时空聚集，表明从先前占据的地点进行了扩张。夏季最低气温较低、春季和夏季降水较多、冬季降水较少的情况下， O. rufus更为丰富。天气条件影响了O. rufus 的丰度，但存在与全球气候变化模式不同的局部变化。
