Abstract

The community structures and seasonal changes of soil microarthropods were investigated in a natural Sessile Oak (Quercus petraea) stand and adjacent Scots Pine (Pinus sylvestris) plantation located in the Belgrad Forest of Istanbul. Soils for microarthropods were sampled monthly using steel soil corers between November 2008 and October 2009. Soil fauna samples were extracted with a modified Berlese-Tullgren funnel and stored in 70% ethanol. A total of 26 taxons of microarthropods were identified in the oak stand and Scots pine plantation. The mean annual number of microarthropods per square meter was 42.851 for the oak stand versus 42.276 for the Scots pine plantation. The Collembola and Acarina are the two dominant taxa in numbers constituting 94% and 93% of all soil microarthropods of the native oak and Scots pine plantation, respectively. The Shannon diversity index (H') of microarthropods in the Scots pine site (1.72) was found significantly (P=0.008) higher than those of the native oak (1.57). This result implies that even though conversion of Sessile oak land to a Scots pine plantation may decrease the abundance but increased the diversity of soil microarthropods.

乡土栎林和苏格兰松林土壤微节肢动物群落结构及季节变化

研究了伊斯坦布尔Belgrad森林天然无柄栎林及其邻近的苏格兰松人工林土壤微节肢动物的群落结构和季节变化。2008年11月至2009年10月，采用钢质土壤覆盖物每月对微节肢动物土壤进行取样。土壤动物标本采用改良Berlese-Tullgren漏斗提取，70%乙醇保存。在栎林和苏格兰松林共鉴定出26个微节肢动物分类群。栎林的年平均小节肢动物数为42.851只/ m2，而松林的年平均小节肢动物数为42.276只/ m2。弹子虫和刺虫是原生栎树和苏格兰松林土壤微节肢动物的优势类群，分别占原生栎树和苏格兰松林土壤微节肢动物总数的94%和93%。小腹节肢动物的Shannon多样性指数(H’)为1.72 (P=0.008)，显著高于本地栎树(1.57)。这一结果表明，尽管无柄栎林向苏格兰松林的转变可能会降低土壤微节肢动物的丰度，但会增加土壤微节肢动物的多样性。

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
