【摘要】 在西双版纳热带植物园内,用活捕笼捕获黄胸鼠12只,以花生、油茶及假海桐为备选食物,在围栏条件下对黄胸鼠的取食及贮藏行为进行了研究.结果表明:黄胸鼠主要集中贮藏食物;与油茶等林木种子相比,黄胸鼠更倾向取食和贮藏花生种子;黄胸鼠在巢外取食的位置一般会位于巢穴与种子释放点之间的区域,这可能是回避捕食风险的反映,每晚在巢内也会取食部分种子;黄胸鼠夜取食种子9.28±2.79g,约占其体重的10%左右.因此,黄胸鼠对林木种子有一定的捕食压力,但对种子扩散作用可能不大.更多还原

【Abstract】 The food hoarding and eating behavior of Tanezumi rat are investigated by providing peanut,oil tea and pittosporopsis craib seeds as foods within enclosures(L×W×H=10×10×1.5 m3)in Xishuangbanna.The results showed that Tanezumi rat hoarded food in larders.Tanezumi rat consumes and hoards more peanut and pittosporopsis craib seeds.The sites where food were eaten distribute between the nest and the feeder.This behavior maybe reflect decreasing predation risk.Tanezumi rat eats part of the hoarded food every night.Tanezumi rat consume 9.28±2.79 g foods,which is equal to 10% of its weight.Tanezumi rat is likely to be a kind of rat harm to farm,while its effect on seeds dispersal and forest renewal is not very obvious.更多还原
