Distribution of Soil Microarthropod in Pine, Oak anD Bamboo Forests with Special Focus on Gamasid Mites
Soil microarthropods play important role in soil food web and contribution the nutrient cycling and soil system health. Among diverse taxa, gamasid mite Acari: Gamasida) is considered as a top predator group in soil ecosystem. We compared the soil microarthropod communities focused on gamasid mite species composition. Soil samples were collected Mt. Cheonju in bukmyeon, Changwon-si, Gyeongsangnam-do. On the mountain hill, contagious pine tree (Pinus densiflora) and oak tree (Quercus acutissima) stand were sampled while the bamboo tree (Phyllostachy bambusoides) stand is located in ap. 200m below from the mountain hill. Soil microarthopods abundance was high in bamboo and pine tree stand, but lower in oak tree stand. The dominance order was oribatid mite, collembolan and gamasid mites in pine tree stand, oribatid mite, insects, and gamasid in oak tree stand while in bamboo stand, oribatid mites were out numbered (75%) followed by collembolan. Collected gamasid mites were 146 individuals and 34 species. Species richness and diversity was highest in oak tree stand and lowest in bamboo stand. Cluster analysis showed highest similar in pine-oak stand to bamboo stand. Dominant species were Holaspina dentatus (Parholaspididae) in pine stand, Gamasus fujisanus, Veigaia sp in oak stand, and Gamasus fujisanus in bamboo stand.
