| 摘 要： | 2007年9月至10月,以贵州省遵义市绥阳县宽阔水国家级自然保护区亚热带森林系统内食果(或食种子)啮齿类动物与肉果植物香港四照花Dendrobenthamia hongkongensis和干果植物西南山茶Camellia pitardii为研究对象,初步研究鼠类捕食对两种植物种子扩散的影响.结果表明啮齿动物对两种植物果实及种子的搬运存在较大差异:鼠类对于肉果植物主要表现为种子的散布者,香港四照花90%的种子被成功散布,但距离较靠近母树;鼠类对于干果植物则主要表现为种子的掠食者,超过90%的西南山茶种子被鼠类采食,仅极少数能够偶然幸存下来进入土壤种子库,鼠类对干果的平均搬运距离大于肉果.

| Abstract: | During September to October in 2007,the fruit-eating (or seed-eating) rodents,a berry plant (Dendrobenthamia hongkongensis) and a nut plant (Camellia pitardii) of subtropical forest system was investigated from Kuankuoshui National Nature Reserve,Suiyang county of Guizhou province to study the influence of seeds dispersal resulting from the predatory activities of rodents.The results showed that rodents made quite different influence on two plants seeds through their activities: for the fleshy fruits,rodent... |
