the effects of invasive woody species on belowground ecosystem of oceanic island

本研究的目的是了解入侵木本物种爪哇比肖菲（Bischofia javanica）对日本小笠原海洋岛屿土壤生态系统的影响。首先，我们比较了小笠原地区土生木本植物爪哇木的叶片功能特征。我们发现，与本地木本植物相比，爪哇木叶片中酚类物质的含量更高。此外，芥蓝可能通过其凋落叶增加了土壤酸度，降低了土壤中酚类物质浓度和微生物活性。

The aim of this study was to understand how an invasive woody species, Bischofia javanica, affect soil ecosystem of oceanic islands, Ogasawara, in Japan. First, we compared the leaf functional traits of B. javanica to those of native woody species in Ogasawara. We found that B. javanica had higher phenolic concentrations in their leaves when compared to native woody species. It is also suggested that B. javanica increased soil acidity and decreased phenolic concentrations and microbial activity in soils probably through their leaf litter.
