The influence of emergent macrophytes (dominated by Phragmites australis (Cav.) Trin. ex Steud.) on the species composition, richness and abundance of epiphytic midges (Diptera: Chironomidae) was studied in five shallow lakes of eastern Poland during three seasons (May, July and October) of 2001. The lakes represented three states: clear (macrophyte dominated), intermediate (phytoplankton-macrophyte dominated) and turbid (phytoplankton dominated). The trophic status of lake strongly affected the assemblages of chironomids living on the surfaces of common reed. Habitat conditions regulated mostly densities and relative abundance of midge taxa and did not have any significant influence on the number of taxa. The Canonical Correspondence Analysis of epiphytic fauna showed the significance of 5 environmental variables: Secchi disc visibility, dissolved oxygen, reed density, concentration of total phosphorous and epiphytic chlorophyll-a. The analysis separated epiphytic midges into two groups. The first group included taxa limited by low oxygen content and water transparency and corresponds with clear state habitats. To the second group belong taxa typical of eutrophic waters with densities determined by the concentrations of total phosphorous and chlorophyll-a, common in lakes of intermediate state and in particular of turbid state.

The distribution of phytoplankton and its relation to the hydrographic features in the north-eastern Adriatic was investigated in February 2008. The area of interest included a thermohaline gradient in the channel situated between the coast and the islands lying parallel to the coast. The gradient is controlled by the influx of oligotrophic karstic riverine water at the south-eastern end,subma rine springs in the middle part,an d warmer offshore waters at the north-western end of the channel. The change of temperature and salinity in the estuarine transition zone was accompanied by abundant diatoms and dinoflagellates below the halocline,with dominant chain-forming diatoms (Chaetoceros, Bacteriastrum) in abundances reaching 5×105 cells dm−3. The impact of coastal submarine springs detected by infrared remote sensing resulted in the growth of cyanobacteria in the nitrogen-depleted surface waters. The greater contribution of picoplankton, as well as of nanoplanktonic coccolithophorids and cryptophytes,in the outer channel system indicated their preference for oligotrophic conditions. Flow cytometric counts of nanophytoplankton were 10–30 times greater than inverted microscope counts. Cyanobacteria were about five times more abundant than picoeukaryotes. The study demonstrates how different techniques (remote sensing and in situ investigations) can be useful in understanding the biological and hydrographic set-up in the specific oligotrophic eastern Adriatic coastal environment.
