Impact of Different Lawn Maintenance on Terrestrial Invertebrate Biodiversity
Klán, Jan ; Říhová, Dagmar (advisor) ; Škodová, Jana (referee)
This paper focuses on differences in the composition of invertebrate communities in grasslands with different management of green space management. It was carried out on four research plots with different management types (no-till, regular treatment with a power mower, treatment with a scythe, treatment with grazing). The main objective of the work is to demonstrate, using a sample of captured spiders, centipedes, millipedes, earwigs, and leafhoppers, which form of grassland habitat management is the most appropriate in terms of biodiversity richness. Other sub-objectives were to obtain local data on the variability of soil moisture in the study plots, air humidity and temperature. These values will illustrate an idea of the habitat of the captured animals. In terms of biodiversity, the grazed habitat proved to be the richest (a total of 84 species captured). This was followed by the no-mow habitat (83 species), mowed (76) and finally mowed with a mower (74). Mowed habitat was the poorest. In all habitats, the highest number of spider species was always captured, followed by crickets, and an order of magnitude fewer millipedes, centipedes, millipedes, and starlings were captured. One species of chrysalis was captured, which is listed on the Red List of Threatened Species of the Czech Republic. This...

Klán, Jan ; Duškov, Ivan (advisor) ; Hedbávný, Petr (referee)
The author valorizes also his practical experiences of a left-oriented politician and first results from sociological research has set an objective to check two hypotheses: 1) that in the conditions of global capitalism development to save and fully revitalize the social state in his conception of a factor that is not only mitigating urgent social inequalities, but also raise the society and cultivates the human being, 2) that in the process of capitalist crises and the crises of a social state, senior citizens living from their pensions belong to the most threatened social groups. Methodologically the author claims to belong to modern Marxism and critically demarcate himself both from stalinism as well as from the recent official ideology, above all neoliberalism. The author refuses also the attempts to equate Marxism and the policy of KSČM to the ideology of the past governing class of controlling apparatus and comprehend the KSČM as a party disguised as Stalinist, anti human and non-democratic and in agreement with the program of this party that it represent in the Parliament of Czech Republic belongs to the self- managed socialism as a long-term objective of a societal transformation. As far as the method is concerned, in the view of a certain interdisciplinarity of the present publication, the...
