摘要
啮齿动物对植物种子的传播,不仅可以使种子逃避被其他捕食者捕食,避开在母株周围的存活竞争,而且得到传播的植物种子可能会建成幼苗,扩大植物种群的分布,实现植物群落的更新。啮齿动物对种子的选择不仅受其自身形态和行为特征的影响,也与种子的形态特征和同域分布的其他动物类群的取食竞争密切相关。啮齿动物传播种子的方式主要为贮食传播,其对植物种子的贮藏分为集中贮藏和分散贮藏,其中分散贮藏对植物种子传播距离远、种子萌发或幼苗建成率高,是最为有效的传播方式。啮齿动物对种子的传播作用还能促进退化生境的恢复,具有重要的生态学意义。本文整理了国内外近年来的主要文献,并结合课题组开展相关研究,重点介绍了啮齿动物在植物种子传播过程中的作用和可能的影响因素,以及几种常用的种子追踪研究方法,以期为同类试验研究提供借鉴。
Rodents play an important ecological role in the transmission of grassland plant seeds.The dispersal of grassland plant seeds by rodents not only allows the seeds to escape predation by other predators,avoid survival competition around the mother plant,but also gets the transmission,builds seedlings,expanding the grassland distribution of plant population,and realizing the renewal of plant community.The selection of seeds by rodents is not only influenced by their own morphological and behavioral characteristics,but also closely related to the morphological characteristics of seeds and the feeding competition of other sympatry animals.The way of seed dispersal by rodents is mainly storage and food dispersal,and its storage of plant seeds is divided into centralizehoarding and scatter-hoarding.The scatter-hoarding is the most effective propagation way for plant seeds with long propagation distance,and high seed germination or seedling growing rate.Rodent seed dispersal also promotes the restoration of degraded habitats,which has important ecological significance.In this paper,the main literatures were summarized at home and abroad in recent years,and the related research were overviewed,which focused the role and possible influencing factors on the process of grassland plant seed dispersal via rodents.Several commonly used seed-tracking methods were introduced as well,with a view to providing references for similar experimental research.
