Vaníčková, Jana ; Hlava, Jakub (advisor) ; Husák, Tomáš (referee)
This bachelor thesis deals with invertebrates, in particular soil invertebrates, which inhabit the anthropogenically influenced enviroment at landfill of municipal waste.
In the theoretical part of this work the most common types of soil invertebrates and basic ecological concepts are described. The practical part included the processing of individual samples and also sampling sites description.
To obtain the material I have chosen four different landfills, where the soil samples were collected. The extraction of soil fauna was realized using Tullgrens extractors.The extracted samples were examined in lab conditions under binocular and the soil fauna were divided into taxonomic groups, according to their morphological characteristics.
Sampling locations did not represent a different ecosystems. The activities are carried out standardly, according to the law. There is a part of restoration area in each locality.
The aim of the practical part was to describe the composition of soil fauna communities in the landfill of municipal waste. Furthermore, this work deals with the comparison of individual sites and for a better interpretation, results are presented by tables and graphs. The observed diversity is interpreted using diversity and evenness indices.
The results show that the most dominant groups forming the fellowship of soil mites without incrusted body (in the work presented as Acari in general). Further, as another of the dominant group I found rich communities of the incrusted Oribatid mites and springtails (Collembola), which are considered as a typical soil fauna.
Most of these representatives was found in Sono landfill, on the other hand the minimum specimen were found in the Tušimice landfill. In the overall evaluation, samples did not represent significant differences in the composition of the soil invertebrates communities.
