【 摘 要 】

We investigated the association of landscaping plants with thecommunities of ground-dwelling arthropods within pastures and tested the hypothesis thatarthropod biodiversity increases with vegetation heterogeneity. The community characterizationand biodiversity of arthropods in a pasture were compared with those within communities withlandscaping plants, including forest remnants, Forsythia koreana and Prunus serotina. The totalabundance of mites was greater within the forest remnants than within the pasture; however,the abundance of insects and spiders did not differ. Nonmetric multidimensional scaling and themultiresponse permutation procedure revealed that the community composition of insects andspiders differed according to vegetation type. The abundance of Teleogryllus emma was highestwithin the forest remnant community, which suggested the species’ dependency on vegetationtype. Species richness and the Shannon index of insects increased within F. koreana but notwithin P. serotina compared with the pasture. This suggested that belts of shrubs might have agreater promoting effect on insect biodiversity than belts of trees. Species richness of spidersdid not differ by vegetation type. The total number of insect and spider species within the studyarea increased by 2.8 and 3.5 times, respectively, by establishing three types of vegetation.These results suggested that increasing vegetation heterogeneity by establishing landscapingplants is a good option for conserving insect and spider biodiversity in pastures.
