| Popis: | The aim of this work was to evaluate the impact of application of defined doses of organic fertilizers (manure and biosludge) to the occurrence of family of Coleopterafaun, during six years long period 2004-2009. Experiment was realized on the locality Kolíňany, by the earth traps method, which were exposed in the five treatments (1st treatment- control treatments ; 2nd treatments- 25 t ha - 1 of the manure ; 3rd treatment- 50 t ha- 1 of biosludge; 4th treatment- 50 t ha - 1 of the manure; 5th treatment- 100 t ha- 1 of biosludge). Every year the traps were exposed in different crops: 2004- Helianthus annuus; 2005– Beta vulgaris; 2006- Zea mays; 2007- Beta vulgaris; 2008 - Hordeum vulgare; 2009 - Helianthus annuus. Altogether there were trapped 60,406 exemplars of Coleopterafaun, that from taxonomic point of view belonging to the 16 families. The year, temperature and precipitation had positive impact on the incidence of families in the year 2009, when we obtained 18,436 ex and in the year 2008, when we found 15,201 ex. Abundance of exemplars during other studied years was significantly lower. Statistical evaluation of the impact of year on an occurrence of families showed significantly (P = 0.05-0.01) for families Anthicidae, Chrysomelidae, Cryptophagidae, Elateridae and Staphylinidae. The statistical evidence was not reflected (P>0.05) for families Carabidae, Coccinelidae, Curculionidae, Dermestidae, Histeridae, Lathridiidae, Liodidae, Nitidulidae, Ptiliidae, Scarabaeidae and Silphidae. In assessment of impact of the year have an important role climatic factors (temperature and precipitation). Impact of temperature and precipitation recorded evidence for families Anthicidae, Chrysomelidae, Elateridae, Staphylinidae. Other families showed no statistically evidence of impact of climatic factors temperature and precipitation. In evaluating of impact of treatment on evidence of families of Coleopterafaun as the most suitable was 1st treatment- control treatment (13,574 ex), 3rd treatment - 50 t ha-1 of biosludge (13,318 ex) then 2nd treatment - 25 t ha-1 of the manure (12,286 ex), 5th treatment - 100 t ha-1 of biosludge (10,904 ex) and 4th treatment - 50 t ha-1 of the manure (10,324 ex). Based on the statistical evaluation the impact of treatment on occurrence of families was not reflected and all values were insignificant (P>0.05). Eudominant representation showed within all treatments and years the family Carabidae, with dominance from 95.53 to 98.32 %. When we comparing the similarity of treatments the values of species identity by Jaccard (IA) ranged from 75.00 to 100.00 % and values of identity of dominance (ID) ranged from 93.71 to 97.58 %. We can conclude that realized anthropogenic inputs does not negatively affect occurrence of present geobiocoenosis. |
