Ecological impacts of coarse woody debris generated by recent substantial tree diebacks are poorly known. In this study, relationships between decay types of wood and tree seedlings established on fallen logs of Japanese red pine damaged by pine wilt disease were investigated at 30 sites along latitudinal gradient in Japan. I found that annual temperature and precipitation gradient affected decay types of log and then indirectly affect tree seedling establishment on the logs. These results indicates that decomposer fungi is the key agent determining the role of coarse woody debris on forest regeneration after tree dieback phenomenon.

最近大量树木枯死产生的粗木质残体的生态影响知之甚少。在这项研究中，木材腐烂类型之间的关系和建立在日本赤松倒日志上的松树枯萎病的影响，在日本沿着纬度梯度的30个地点进行了调查。研究发现，年平均气温和年平均降水量梯度影响了原木的腐朽类型，进而间接影响了在原木上的成苗。这些结果表明，分解真菌是决定树木枯死后粗木质残体对森林更新作用的关键因子。
