摘要: 分散贮藏食物是许多啮齿动物所采取的一种重要的觅食策略.分散贮藏方式对于植物的幼苗建成、更新、群落演替和生态系统功能的维持有着积极的意义.多种因素影响啮齿动物对食物分散贮藏.内部因素有性别、年龄、社群关系、饥饿状态等;外部因素包括食物特征、竞争与盗食环境条件等.这些因素并非独立地发挥作用,内部因素受外部刺激的综合影响,而且外部因素只能通过改变动物的内部状态才能发挥作用.特别是在一些室内的或围栏实验中,实验设计的差异不仅影响动物的食物贮藏及其管理,也会造成实验结果的不同.

Abstract: Scatter hoarding,employed by a variety of rodents,can play a positive role in seedling recruitment,plant regeneration,succession of communities and the maintenance of ecosystem.In order to maximize the benefit from food-hoarding,rodents will manage their caches through various ways,e.g.,optimal transporting distances,distributing their caches in wide space in an optimal density,and minimizing the loss of hoarded food.Many factors potentially influence the management of scatter-hoarded food of rodents,which can be classified into internal and external factors.The internal factors refer to sex,age and social relationship,while the external factors may include food characteristics,competition and pilferage,environmental conditions,and so on.These factors are correlated functionally rather than independently.Protocols of experiments within enclosures or arena can affect not only the food-hoarding and management of rodents but also the results of studies.Some important factors,such as predation risk,age and sex of animal,should be considered in the future studies.The more we learn about the management of scatter hoarding,the better understanding we will have on the interaction between rodents and various plants.
