摘要:

目的 研究夏季迁移期洞庭湖区的东方田鼠在防洪堤坝上的食性,分析其食物组成和利用特点。方法 采用夹夜法,于2009年6、7月以及2010年7月在洞庭湖区防洪堤坝上捕捉东方田鼠;采用胃内容物显微组织分析法分析其食物组成。结果 该鼠在防洪堤坝上主要取食的植物为狗牙根、白茅、苍耳等,分别占鼠胃内容物中可辨识食物的17.93%、11.44%和13.50%,主要取食部位为植物的叶,其次是茎,偶尔也取食部分植物的种子、树皮。结论 洞庭湖区的东方田鼠能够取食多种植物,对环境有良好的适应能力。

Abstract:

Objective To determine food composition and utilization of migratoryreed vole (Microtus fortis) inhabiting the Dongting Lake area during summer months. Methods The night trapping method was used to catch reed voles. Their gastric contents were analyzed using the microhistological identification to determine contents and food composition. Results Voles in the area primarily fed on leaves and stems of herbaceous plants, and occasionally seeds and bark. Their main diet consisted of Cynodon dactylon, Imperata cylindrical, and Xanthium sibiricum which accounted for 17.93%, 11.44%, 13.50% of recognizable stomach contents, respectively. Conclusion M. fortis in the Dongting Lake area fed on a variety of plants, indicating great capabilities to adapt to diverse environments.
