结果表明：1。五趾跳鼠是以植物性食物为主的杂食性啮齿动物，对植物性食物具有较强的择食性，放牧制度对该特性影响不显著；五趾跳鼠在短花针茅草原连续放牧区和轮牧区内的植物性食物组成相似度为0.71~0.88，采食频率最高的三种植物是冷篙、无芒隐子草和木地肤。2。

It is also suggested that the evolution of seed dis-persal systems is mainly determined by a few key dispersers and plants, which may control the evolutionof related traits of other species.

动植物之间还可能发生在种、属或科水平以上的多物种的多配协同进化，或者通过关键种的协同进化来带动其他食果动物和植物相关性状的进化。

The many problems encountered by authors trying to argue that herbivory benefits consumed plants suggested that these authors may be forcing an incorrect interpretation on their data.

这些作者在试图争辩食草性对被吃对象的植物有益所遇到的多处问题显示出这些作者可能正把不合理的解释强加给他们的资料数据。

The main influential factors on the change of community structure were discussed in this paper. It was thought that the inherited attribute of plant decided the dominance of E. nuttallii and H. verticillata in local plant community; and the herbivory preference of the snail on P malaianu and V spiralis speeded up the occupancy of dominance by other 2 plants.

作者对调节沉水植物群落结构的影响因素进行了探讨，认为植物种类的生长特性使伊乐藻与轮叶黑藻在与苦草及马来眼子菜的竞争中占优势，椭圆萝卜螺的牧食损害则加速了这种优势地位的取得。

The evolutionary purpose of rubber, and the reason why it has appeared independently in plants as diverse as trees, guayule and dandelions, is that it gums up the mouthparts of herbivorous insects.
