도시림 내 서식처별 중기문응애류 다양성: 서울숲 사례 연구 = Diversity of Mesostigmatid Mites in Different Habitats in the Urban Forest Park: Case Study on Seoul Forest

다국어 초록 (Multilingual Abstract)

Urban forest park is the place of vegetational remaining in the large human settlement area, playing important roles in ecology and human relaxation as well. Biodiversity is the critical driver of the urban forest functioning in terms of ecosystem service. We studied the diversity of soil dwelling predatory mites (Mesostigmatida, Acari) in the Seoul Forest, one of the newly developed urban forest in the Seoul metropolitan city. Soil mesostigmatans were collected from the surface soil (.10 cm depth) of tree stands of Quercus variabilis, Pinus densiflora, Ginkgo biloba, Hibiscus syriacus each and herbaceous plots of Hosta longipes, or Carex sp. Species richness was highest in the oak tree stand and the abundance was highest in Hibiscus stand. In the herbaceous sites, species richness and abundance were extremely low. Similarities of mesostigmatid mite communities among sites were lower than 0.5 of Sørensen`s or Jaccard`s coefficient. Dominant species were Holaspina communis under Q. variabilis stand, Rhodacarus denticulatus and H. communis under P. densiflora, Neogamasus tikhomirovi under G. biloba. Under H. syriacus, phytoseiid mites including Neoseiulus makuwa were exclusively collected. From the herbaceous sites, Hypoaspis cuneifer and H. vacua were collected from H. longipes site and N. tikhomirovi and H. alstoni were from Carex site. Further study of the ecological roles of different predatory mites to the functioning of the urban forest park could help maintain the ecosystem service provided from the urban forest and its management.
