Abstract

The aim of this study was determining and comparing diatom diversity and dominant taxa in 4 seasons from the Crnica River. A total of 170 diatom taxa, 24 among them as dominant ones were recorded. The highest diversity expressed in number of taxa was observed in the spring (139) and the lowest in the autumn season (94). The most of 45 the best fitted taxa on the CCA ordination diagram are recorded in more than two seasons, often in all four seasons. One group of taxa (e.g. Hanaea arcus, Meridion constrictum, Navicula gregaria, N. lanceolata) was characteristic only for spring and other for winter season (e.g. Gomphonema innocens, G. lagenula, Stauroneis phoenicenteron, Nitzschia oligotraphenta). There were no taxa exclusively recorded only in summer and autumn.

克尼察河硅藻多样性和组成的季节变化

本研究的目的是测定和比较克尼察河4个季节硅藻的多样性和优势类群。共发现硅藻170种，其中优势种24种。多样性表现在春季最高(139)，秋季最低(94)。在CCA排序图上最适合的45个分类群中，大多数在两个季节以上记录，通常在四个季节都记录。一个类群(Hanaea arcus, Meridion constrictum, Navicula gregaria, N. lanceolata)只在春季有特征，另一个类群(Gomphonema innocens, G. lagenula，耳鼠耳鼠，Nitzschia oligotraphenta)只在冬季有特征。在夏季和秋季没有专门记录的分类群。
