| 中文摘要: |
| 2007年6月下旬洞庭湖区东方田鼠(Microtus fortis calamorum)再度暴发,作者观察到其种群暴发期间的迁移、栖息与取食行为具有典型的"逃难"与临时"集群"特征,大多数东方田鼠在迁移过程中死亡,迁到大堤的鼠聚集在大石下、木头下、矮灌木和草丛等较隐蔽场所,一个月后扩散到农田和荒地中,多扩散到杂草茂盛的荒地内。迁移过程中不仅取食农作物,而且取食老树皮等,农作物损失严重。了解其在迁移期间的行为特征,可为了解东方田鼠的生活史适应特性和防控东方田鼠危害提供依据。 |
| 英文摘要: |
| The population of Microtus fortis calamorum had entered one peak of multi-annual population fluctuation since 2005 in Dongting Lake Area.Some behavior of M.f.calamorum was observed during migration from beach and island habitat to farmland due to population outbreak,in 2007.The migration from beach and island habitat to farmland was with characteristic of looking for refuge.A majority of population died during migration while the survivals crowded many temporary colonies under stone,fallen tree,brushwood or tussock,and other coverts when they got at dike.One month later,the voles distributed into farmland and uncultivated land.They gathered in area with flourishing the weed,and fed on all eatable plant during migration,as well as the bark of blasted trees.So,they damaged the crops seriously during their migration.It will be helpful to control the harm and to learn their life history by understanding their migration behavior. |
