| 摘 要： | 季节变化是影响鼠类扩散植物种子的一个主要环境因素.2008年9-11月(秋季)和2009年3-4月(春季)分别在秦岭南坡的佛坪国家级自然保护区内调查了森林鼠类对锐齿栎种子的扩散,并与种子大小年假说的预测进行了比较分析.结果表明:春季锐齿栎种子的扩散速度比秋季快,平均扩散距离(取食距离和贮藏距离)也比秋季远,该结果与种子...

| Abstract: | Seasonality is a key environmental factor affecting the seed dispersal by rodents. From September to November (autumn) in 2008 and from March to April (spring) in 2009,investigations were made on the dispersal of Quercus aliena seeds by forest rats in the Foping National Nature Reserve on south slope of Qinling Mountains,and the results were compared with the prediction from mast seeding hypothesis. It was shown that 1) the seed dispersal speed was significantly faster in spring than in autumn,and the mean ... |
