| 摘 要： | 华山松(Pinus armandii)是广泛分布在中国中西部海拔1000～3300m的山地、种子较大(约300mg)的松属植物。为探究华山松种子大小对啮齿动物贮藏行为的影响,于2006年和2007年在滇西北3个不同地点进行种子标记和追踪实验。结果表明,在所有年份和地点,啮齿动物都倾向于贮藏更多的大种子和取食更多的小种子;啮齿动物贮藏大种子的数量,以及平均距离和最大距离均显著高于小种子。3个地点具有不同的啮齿动物群落结构,从而对种子命运产生显著影响。种子命运在两个年份间也存在显著差异。

| Abstract: | Pinus armandii,a native pine species,has large(about 300 mg),wingless seeds,and distributes from central to western China at an altitude of 1 000-3 300 m.To determine how the seed size affects rodents caching behavior,tagged seed releasing and tracking experiments were conducted at 3 sites in Northwest Yunnan province in 2006 and 2007.Our data indicated that for all sites and both years,compared with the smaller seeds,the proportions of cached large seeds were significantly higher,whereas the consumed ones ... |
