Diversity and microcystins content of cyanobacteria in fish ponds (South Moravia, Czech Republic) related to fishery management intensity
Kopp, Radovan ; Ziková, Andrea ; Adamovský, Ondřej ; Brabec, T. ; Straková, L. ; Mareš, J.
During the vegetative period of the years 2005-2007 (June--October) we carried out hydrobiological and hydrochemical monitoring of selected ponds inhered in Southern Moravia in relation to different fishery management intensities. Water temperature, dissolved oxygen content, pH, conductivity and water transparency were monitored directly at taking place, N--NH4+, N--NO2-, N--NO3-, P--PO43- content and chlorophyll-a concentration were measured in hydrochemical laboratory.

Symposium molekulární biologie sinic /7./
Komenda, Josef ; Flores, E. ; Nixon, P. J. ; Waleron, K. ; Maršálek, Blahoslav
The conference was devoted to the recent advances in the field of molecular biology of cyanobacteria, namely in the structure and function of important proteins and their complexes, in the regulation of gene expression, in cell differentiation, in cellular metabolism and in molecular ecology and taxonomy. There were 170 participants presenting 101 posters and 12 invited and 29 selected lectures including a computer bioinformatics session

Distribution and expansion of planctic cyanobacteria in Czech Republic
Komárek, Jiří ; Komárková, Jaroslava
Planktic cyanobacteria play important role in freshwater habitats in Czech Republic. They develop sometimes in massive water blooms, produce cyanotoxins and must be monitored from hydrobiological and sanitary point of views. Frequency of their occurrence and the species composition change in time and depend on managing of water ecosystems and on global changes of climate. The distribution and occurrence of various species in Czech Republic over last 60 years is reviewed.
