DIVERSITY AND THE MAIN ECOLOGICAL REQUIREMENTS OF THE EPIGEIC SPECIES OF FOREST ECOSYSTEMS IN THE SIBIU COUNTY, IN THE YEARS 2013-2014

Epigeous insects in the “Dumbrava Sibiului” oak forest were captured between 2013-2014. From April to September in each year. 12 traps were installed in a circle 147 individuals collected belonged to 28 species and 6 families: Carabidae ? 14 species (50.0%), 187 individuals (77.37 %), Staphylinidae ? 7 species (25.0 %), 15 individuals (6.17 %), Silphidae ? 3 species (10.72 %), 29 individuals (11.93 %), Elateridae ? 1 species (3.51 %), 1 individual (0.41 % ), Scarabaeidae ? 2 species (7.14 %), 8 individuals (3.29 %), Forficulidae ? 1 species (3.51 %), 2 individuals (0.82 %)). Also, we presented in tables the ecological requirements of the species of Carabidae collected, the variation of their relative abundance and the structure of dominance Composition of species corresponded to communities from drier forms of irregularly flooded the floodplain forests with decreased level of ground water, known from Central Europe.
