Abstract

Abstract Oribatid fauna highly varies among habitats, but different microhabitats within a habitat are also characterized by different mite species. The main goal of the research was to compare the observed structure of an oribatid community when samples were collected at random from the soil-litter layer of 0-10 cm in depth (standard approach) and selectively from 6 types of available microhabitats (complex approach). Samples were taken within a small plot (10 m × 10 m) in a forested area of the Silesian Park (Chorzów, south Poland). Overall, 2642 specimens of Oribatida belonging to 62 species were collected in 66 samples. The structure of the oribatid community observed by means of the 2 sampling approaches was completely different. The abundance and species richness of oribatid mites collected from 6 microhabitats were significantly higher than in the soil-litter layer alone. Results of this study show that random collecting of only soil-litter samples may reduce the evaluation of species richness in a study area by 40%. Each of the studied microhabitats supported a peculiar oribatid fauna.
微生境与甲虫区系:两种取样方法的比较
不同生境的甲螨区系差异很大,但同一生境内不同微生境的螨种也不同。本研究的主要目的是比较在0 ~ 10 cm深度的土壤凋落层中随机取样(标准取样法)和在6种可选微生境中选择性取样(复杂取样法)所观察到的甲虫群落结构。样本是在西里西亚公园(Chorzów,波兰南部)的一个森林地区的一个小地块(10米× 10米)内采集的。共在66个标本中采集到甲螨62种2642只。两种取样方法所观察到的甲虫群落结构完全不同。6个微生境采集的甲螨的丰度和物种丰富度均显著高于土壤凋落物层。研究结果表明,仅随机采集凋落物样本可能会使研究区物种丰富度评价降低40%。每一个被研究的微栖息地都支持一种特殊的甲虫动物群。
