Mechanisms of bio-diversity in Japanese beech forests by using molecular markets.

2.在落叶阔叶林中，我们阐明了树叶物候学(即叶片出现的时间)在决定树种更替和物种多样性中的重要性。3.在初级山毛榉森林中，底层灌木绣球花的生活史策略受到上层乔木树冠动态的强烈影响，表明这两个物种通过补偿相互作用而共存。4.在一个大的永久立地(6ha)中，5.在原始山毛榉林中，利用高变量微卫星标记，对每一株成年树的种子扩散和遗传多样性的机制进行了亲子分析和母本分析。6.提出了一种基于种子、果实和幼苗母组织微卫星分析的母树鉴定方法。7.在几个破碎的山毛榉森林中，遗传多样性(He、Rs、Fis)与对照成熟林没有什么不同。

1.Janzen-Connell mechanisms were observed in juvenile stages of both species, Fagus crenata and Purunus grayana in a Japanese beech forest.2.In a deciduous broad-leaved forest, we clarified the importance of leaf phenolgy (i.e.timing of leaf emergence) in determining replacement of tree species and species diversity.3.In a primary beech forest, life history strategies of a understorey shrub, Hydrangea paniculata, are strongly affected by the canopy dynamics of overstorey trees, suggesting the co-existence of the species by compensating interactions.4.In a large permanent site (6ha), we found dose relationships between species-diversity and topographic conditions.5.In a primary beech forest, paternity and maternity analysis were conducted to clarify the seed dispersal of each adult trees and mechanisms of genetic diversity of Japanese beech, by using hypervariable microsatelite markers.6.We present a new approach for the identification of the mother trees based on microsatelite analysis of mother tissues from seeds, fruits and seedlings.7.In several fragmented forests of Japanese beech, the genetic diversity (He, Rs, FIS) was not different from that of the control mature forest.
