Algal community patterns in Slovenian bogs along environmental gradients

In 2005 and 2006, epiphyton samples were collected from seven lowland and montane peat bogs in Slovenia. Water temperature, pH, conductivity, dissolved oxygen and saturation were measured at the same time. Diatoms, desmids and Cyanobacteria were the most abundand groups in species number. Canonical Correspondence Analysis (CCA) was carried out on Cyanobacteria, diatom and desmid flora composition. This analysis showed that shading was the most important parameter in Cyanobacteria distribution and bedrock the most important one in that of diatoms and desmids. Cluster analyses were carried out based on the Cyanobacteria, diatom and desmid data. The Cyanobacteria and diatom data separated sites, whereas the desmid data revealed a temporal aspect.
