abstract:
The research was carried out on a shallow, macrophyte-dominated mid-forest water body. The aim of the study was to analyse the impact of various macrophyte habitats, differing in the spatial structure and biomass, representing four ecological groups (helophytes, submerged elodeids, nymphaeids and stonewort meadows) on the zooplankton communities. There were 110 zooplankton species identified, however, the macrophyte stands were characterised by richer taxonomical structure and higher species biodiversity index than the open water zone between particular plant beds, a result of the greater mosaic of the vegetated biocoenoses which create more ecological niches compared to the open water area. The analyses of zooplankton communities in 2002 and 2004 revealed that along with the syntaxonomical rebuild in the submerged vegetation cover the structure of zooplankton communities, including the quality structure, abundance and the dominating species, had also changed. Out of the total of 23 dominating species only 4 dominated in both years.
