Druhové spektrum střevlíkovitých (Carabidae) v porostech polních plodin
Hurajová, Erika
In the stands of winter oilseed rape, winter wheat and corn on parcels in Miroslav I investigated species representation of ground beetles (Carabidae). I carried out using collections of ground traps at ten-day intervals. To each crop I ranked 5 ground traps. I founded ground traps 18. 5. 2016 and kept to the land to harvest crops (oilseed rape 3. 7. 2016, wheat 27. 7. 2016 and corn 15. 10. 2016. I caught a total of 371 individuals from the ground beetles of 29 species. I caught in the oilseed rape 72 individuals from 13 species, in wheat 128 individuals from 16 species, in corn 171 individuals from 18 species. I classiffied species in to bioindicatory groups: 44,83 % E, 51,72 % A, 3,44 % R. I used ecology characteristics: presence, absence, dominance, Simpsons index, constance, species diverzity, equitability and faunistic similarity.

Epigeičtí bezobratlí vybraných porostů polních plodin
Hurajová, Erika
The species representation of the epigeic invertebrates was found on the grounds of Miroslav. I compared oilseed rape, wheat and maize. The invertebrate capture was done using the method of soil traps. In each crop, I set up 5 ground traps on 28. 4. 2018. I pick up samples from the soil traps at ten-day intervals. The last collection was made on the day of the harvest of the crop (oilseed rape 20. 6. 2018, wheat 9. 7. 2018, maize 5. 8. 2018). I focused on the family of ground beetles (Carabidae). I totally caught 488 individuals from 25 species. In the oilseed rape I caught 231 individuals of 19 species, 102 individuals of 17 species in wheat and 155 individuals of 16 species in maize. I have divided species in the bioindicator groups: E 48%, A 52%. I used ecology characteristics to compare field crops: presence, absence, dominance, Simpsons index, constance, species diverzity, equitability and faunistic similarity.
