ABSTRACT

Forest ecosystems have high biodiversity with ecologically diverse animals and plants. The forest canopy supports high biodiversity, and canopy insects are important components owing to their high species richness and abundance. Although many studies have investigated the vertical stratification of arboreal insects, the formation process of geographic patterns in the arboreal insect community structure is not well understood. We analyzed arboreal insect communities in Japanese beech forests in northern Japan to examine their formation process of geographic pattern with geographic distance. We set eight study sites and collected insects monthly from June to September 2015 and 2016. We collected 2070 individuals from 479 species in 14 orders. We tested for nested structure in communities by distance and examined the correlation between the geographic distance and the dissimilarity of community structure. The insect community structure was nested by distance. When we classified insects by order into herbivore or carnivore, we found a positive correlation in herbivorous Hemiptera, while we were not able to find any correlations in other taxa. We collected a number of arboreal insect species that also occur in southern Japan at some sites. These results suggest that the arboreal insect communities in northern Japan change with geographic distance because they include taxa with a poor dispersal ability and some species from the southern beech forest along with the mountain area.

日本北部山毛榉林树栖昆虫群落结构的地理格局

摘要

森林生态系统生物多样性高,动植物生态多样。森林冠层支撑着高度的生物多样性,而冠层昆虫因其物种丰富度和丰度而成为重要组成部分。虽然许多研究已经调查了树栖昆虫的垂直分层,但树栖昆虫群落结构中地理格局的形成过程尚不清楚。我们分析了日本北部日本山毛榉林中的树栖昆虫群落,以考察其地理格局与地理距离的形成过程。从 2015 年 6 月至 2016 年 9 月和 2016 年,我们设置了 8 个研究地点并每月收集昆虫。我们从 14 个目中的 479 个物种中收集了 2070 只个体。我们通过距离测试了社区中的嵌套结构,并检查了地理距离与社区结构差异之间的相关性。昆虫群落结构按距离嵌套。当我们按顺序将昆虫分类为食草动物或食肉动物时,我们发现食草半翅目中存在正相关,而在其他类群中我们没有发现任何相关性。我们收集了一些也出现在日本南部某些地点的树栖昆虫物种。这些结果表明,日本北部的树栖昆虫群落随着地理距离的变化而变化,因为它们包括传播能力差的类群和一些来自南部山毛榉林和山区的物种。当我们按顺序将昆虫分类为食草动物或食肉动物时,我们发现食草半翅目中存在正相关,而在其他类群中我们没有发现任何相关性。我们收集了一些也出现在日本南部某些地点的树栖昆虫物种。这些结果表明,日本北部的树栖昆虫群落随着地理距离的变化而变化,因为它们包括传播能力差的类群和一些来自南部山毛榉林和山区的物种。当我们按顺序将昆虫分类为食草动物或食肉动物时,我们发现食草半翅目中存在正相关,而在其他类群中我们没有发现任何相关性。我们收集了一些也出现在日本南部某些地点的树栖昆虫物种。这些结果表明,日本北部的树栖昆虫群落随着地理距离的变化而变化,因为它们包括传播能力差的类群和一些来自南部山毛榉林和山区的物种。
