This work deals with the influence coppice management on the structure and diversity of coppice forest in Turkey (Southeastern Europe). Data are characterizing the local natural conditions in the school forest area of Istanbul University. The structure was measured by Field-map, 46 plots with a radius of 9 m (254 m2). The data were analyzed in the R statistic programme. It was found that the influence of habitat and exposure to the representation of individual tree species is statistically significant. Abundance of species was significantly higher in the active coppice. Shannon's diversity index was the highest at hill exhibition. Species evenness (Evenness) EH increased proportionally with the content of calcium (Ca) in the soil.

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.
