Floristic study of cyanobacteria and algae in south-east part of Vysočina region
MELICHAR, Antonín
The phytoplankton samples from 45 localities in Vysočina region were collected in 2009. Species composition and relative abundance of species were studied; ecological factors like pH, conductivity, temperature, water transparency and dissolved ions were measured. Ecological indices (Shannon and Simpson index of diversity) were calculated and compared with other ecological factors. Checklist of all species present in Vysočina region was made. There were found 262 species and 4 species new for the Czech Republic.
