Invertebrates in contaminated ecosystems - landfills
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.
The characteristic of 8th forest vegetation stage and present possibilities of its evaluace (assess) with functional diagnostics
Rychtář, Jan
The article deals with issue of 8th. forest vegetation stage in natural forest area 13 – Šumava. It describes klimatic and stational conditions of stations, present and climax associations from the perspective of different classification systems. The article also explains the options and methods of functional diagnostics source of objective information this associations with the first measured outputs of the study area.
Makrozoobentos řeky Svratky -- změny složení společenstva makrozoobentosu v podélném profilu
Kadeřábek, Petr
This thesis deals with the observation of a change of macroinvertebrate in the longitudinal profile of the river Svratka. The monitoring of macroinvertebrate was accomplished at se-ven locations of the Svratka river during the july of 2012. Samples were collected from various locations by the workers of Mendel university and subsequently processed and determined in the university laboratory by the author of the thesis. The diversity of species and thein abundance were evaluated. On these seven sites were found a total of eleven groups of macroinvertebrate, with the largest groups of Ephemeroptera, Coleoptera, Dipte-ra and Trichoptera The taxonomic composition and abundance were evaluated from the obtained data. Both factors were changing towards the flow of the river. Taxonomic com-position got richer and abundance got slightly increased. The taxonomic composition of macroinvertebrates was changing in the longitudinal profile of the river. The examined stretch of the river Svratka is relatively stable, no significant changes were noted.
