Research Abstract

Nematodes were isolated from soil in natural forests of Fagus crenata and plantations of Cryptomeria japonica after clear-cutting of F. crenata. DNA typing of the nematodes using barcode sequence (18S rDNA) were done. In total, 235 MOTUs (molecular taxonomic operational units) were detected. Diversity index or some index based on nematode feeding type were not significantly different between beech forests and conifer plantations. The results suggested that diversity of soil nematode fauna in conifer plantations persisted after clear-cutting.
