虽然有关鼠类搬运森林种子的证据已很清楚 ,但这些被移走种子的存活情况却知之甚少。提出了一个新的标记和跟踪种子的方法——标签法 ,即将种子拴一带有编码的细长金属片 ,研究了北京东灵山地区山杏 ( Prunusarmeniaca)种子的扩散距离和存活率。于 1 998年 6月 1 9～ 2 0日 ,7月 3日和 1 0月 2 3日共在 2 4个样点释放 1 4 4 0粒山杏种子。几乎所有释放的种子在 1 0 d内被鼠类取走。夏天释放的种子比秋天释放的种子消失的速度快。大多数种子的扩散距离在 2 0 m以内 ,小于鼠类的活动距离。鼠类吃掉种子的速度很快 ,但当种子变得稀少时 ,种子存活率有所提高。山杏种子 6、7月份的每日存活率小于其它月份的每日存活率
Although the evidence on the handling of forest seeds by rodents has become clear, little is known about the survival of these seeds that have been removed. A new method of labeling and tracking seeds-tagging method was proposed, in which the seeds were tethered to an elongated piece of metal with an encoding to study the diffusion distance and survival rate of Prunus armeniaca seeds in Dongling Mountain, Beijing. A total of 1440 apricot seeds were released at 24 sampling sites from 19 to 20 June 1993, from July 3 and from January 23 to January 23, Almost all the released seeds were removed by the rats within 10 days. Seeds released in summer disappear faster than seeds released in autumn. Most of the seeds of the spread of less than 20m, less than the activity of the mouse. Rodents eaten seeds very quickly, but when the seeds became sparse, the seed survival rate increased. Apricot seed in June and July, the daily survival rate is less than the other months of the daily survival rate
