Abstract

We investigated the association of landscaping plants with the communities of ground-dwelling arthropods within pastures and tested the hypothesis that arthropod biodiversity increases with vegetation heterogeneity. The community characterization and biodiversity of arthropods in a pasture were compared with those within communities with landscaping plants, including forest remnants, Forsythia koreana and Prunus serotina. The total abundance 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 the multiresponse permutation procedure revealed that the community composition of insects and spiders differed according to vegetation type. The abundance of Teleogryllus emma was highest within the forest remnant community, which suggested the species’ dependency on vegetation type. Species richness and the Shannon index of insects increased within F. koreana but not within P. serotina compared with the pasture. This suggested that belts of shrubs might have a greater promoting effect on insect biodiversity than belts of trees. Species richness of spiders did not differ by vegetation type. The total number of insect and spider species within the study area increased by 2.8 and 3.5 times, respectively, by establishing three types of vegetation. These results suggested that increasing vegetation heterogeneity by establishing landscaping plants is a good option for conserving insect and spider biodiversity in pastures.
牧场陆生节肢动物的组成、丰度、生物多样性及其与园林植物的关系
研究了景观植物与草场地栖节肢动物群落的关系,并验证了节肢动物多样性随植被异质性而增加的假说。对草地节肢动物的群落特征和生物多样性进行了比较,比较了森林残草、连翘和李的群落特征。螨类总丰度在森林残余物中大于在草场中;然而,昆虫和蜘蛛的数量并没有什么不同。非度量多维尺度和多响应排列过程表明,不同植被类型的昆虫和蜘蛛的群落组成存在差异。在森林残林群落中,长尾草的丰度最高,表明该物种对植被类型有一定的依赖性。与草地相比,柠条内昆虫的物种丰富度和Shannon指数增加,而柠条内昆虫的Shannon指数没有增加。这表明灌木带对昆虫多样性的促进作用可能比乔木带更大。蜘蛛的物种丰富度不受植被类型的影响。通过建立3种植被,研究区内昆虫和蜘蛛的种类总数分别增加了2.8倍和3.5倍。这些结果表明,通过建立景观植物来增加植被异质性是保护牧草昆虫和蜘蛛生物多样性的良好选择。
