Effects of forest succession on dispersal patterns for fagaceous trees in an abandoned secondary forest.

我调查了与次生森林演替相关的环境变化对豆科树木扩散模式的影响，这些树木是日本西部暖温带森林的重要组成部分。即使在支离破碎的城市森林中，生物之间的相互作用，如昆虫、木鼠和橡子之间的相互作用，对于豆科树木的初步建立也是重要的。圆锥是一种耐荫的顶极树种，森林演替过程中林鼠捕食行为的变化会对其扩散格局产生显著影响。

I investigated effects of environmental changes associated with secondary forest succession on dispersal patterns for fagaceous trees, which are important component species in a warm-temperate forest in western Japan. Even in a fragmented urban forest, the importance of biological interactions, such as interactions among insects, wood mice and acorns, was suggested for the initial establishment of fagaceous trees. For Castanopsis cuspidata, which is a shade-tolerant climax species, changes in chaching behavior of a wood mouse (Apodemus speciosus) associated with forest succession would significantly affect their dispersal pattern.
