Abstract

The marsh rat (Holochilus chacarius) is considered a specialist herbivorous rodent. In this study, we report the first predation event of an anuran (Pseudis platensis) by a marsh rat in the Pantanal wetlands, South America. This unprecedent event in a flooded wetland in the municipality of Corumbá, Mato Grosso do Sul state, southwestern Brazil. Due to the flashlight, the rodent ceased its predatory activity and left, carrying the anuran in its mouth. Our findings contribute to the natural history of the marsh rat, highlighting that this herbivorous rodent can incorporate fresh animal matter into its diet.

南美洲中部潘塔纳尔（Pantanal）湿地发生的第一次Holochilus chacarius捕食无尾类动物事件

沼鼠（Holochilus chacarius）被认为是一种专门食草的啮齿动物。在这项研究中，我们首次报告了沼鼠在南美洲潘塔纳尔湿地捕食无脊椎动物（Pseudis platensis）的事件。这次捕食事件发生在巴西西南部南马托格罗索州科伦巴市的一片洪水泛滥的湿地。由于手电筒的照射，啮齿动物停止了捕食活动，叼着无尾熊离开了。我们的研究结果有助于了解沼鼠的自然史，突出表明这种草食性啮齿动物可以将新鲜的动物物质纳入其食物中。
