| 摘要: |
| 本文报道了作者在1994年秋季至1995年冬季利用PFU(PolyurethaneUnitFoam,聚氨酯泡沫塑料块)人工基质和结合传统的采集自然基质方法研究德国柏林市郊Stechlin湖原生动物群落多样性特征的结果,通过连续采样调查,首次记录了该湖128种原生动物.实验结果表明:在相同采样时间内,3个不同生境类型的采样站PFU原生动物的群集速度及个体丰度存在明显差异;在相同采样时间和地点,PFU人工基质能够采集到比自然基质更为多的原生动物种类,从而进一步证实了PFU方法应用在原生动物群落多样性研究上的优势作用. |

| Abstract: |
| This paper deals with the results with regard to protozoan community diversity of Stechlin Lake in Berlin Germany, conducted during November 1994 and January, 1995. About 128 species of protozoa have been first recorded following the examination of colonization on polyurethane foam unit (PFU) artificial substrates and various types of natural substrates in this lake. The differences in species richness individual abundance and rates of PFU protozoan colonization at three sampling sites with the different habitat conditions are described. Based on analysis and comparison, PFU can collect more protozoan species than natural substrates do. The results of this research provide further evidence that the PFU method offers the advantages of sampling protozoa compared with other routine collecting methods. |
