Description
In Shiiba Research Forest, we clarified the effect of the presence or absence of understory vegetation on the soil collembolan community at two sites with different situations. Study site A is a mixed forest with steep slopes, and study site B is a secondary forest of Japanese red pine on a gentle slope. The understory vegetation of the site A is Sasa borealis (dwarf bomboo), and that of the site B is Pieris japonica (Japanese andromeda). In each site of A and B, dense understory plots and no understory plots were established. Then, the abundance, species richness, species diversity, trait mean value, and functional diversity of the Collembola community composition. We used a edaphic adaptation score that scored adaptability to deeper soil related to lifeform of Collembola species. Abundance and species richness of Collembola community were significantly reduced in no understory plots in the site A and not significantly changed in the site B. The species diversity, trait mean and functional diversity did not change significantly with or without understory vegetation. The species composition did not change at the Site B, but did change at the site A. From the correlation analysis, the decrease in abundance of the site A was due to decline of understory vegetation. In addition, changes in the abundance of Collembola between with and without understory was observed only in the site A, suggesting that the diversity-preserving function of soil Collembola in the understory may be exerted on steep slopes with dwarf bamboo but not on gentle slopes with andromeda.
