Botanical survey of the Jedlový potok stream (Šumava National Park) three years after a hydrological restoration
ČERMÁKOVÁ, Monika
The Jedlový potok is situated in the Šumava National Park and it is a part of the Hornovltavský luh wetland komplex. In the 1950s, due to peat extraction, the stream was regulated and it drained the surrounding area including its floodplain. After a project creation and approval, part of the stream bed was restored, in 2015. Since then four ambient habitats have been monitored annually. Two permanent plots were set on each of them. The aim of the thesis was to record flora and vegetation on these plots in the fourth year after its restoration. Two types of habitats are located in a close vicinity of the stream bed. These are species-rich wet Cirsium meadow and dense vegetation of Phalaris arundinacea marsh with a dominant species Phalaris arundinacea. The other two habitats have a peaty character and they are located out of the riparian zone, further away from the stream. These are short-sedge fen and species-poor Eriophorum vaginatum mire. The used methods included fytocenologic relevés and also groundwater level measurement. In the whole area a total of 83 plant species were identified. The data of this thesis, also with other acquired data from the Jedlový potok area, are useful for further tracking of the vegetation development and also aids to find out if the restoration helped to recover the hydrologic connection between the stream and its surroundings.
Predikace druhového složení těžeben na základě biotopového mapování okolní krajiny: využití charakteristických druhů vyšších rostlin
SLABA, Michal
The surrounding habitats play an important role in the spontaneous vegetation succession in disturbed sites. They serve as donor sites for species colonizing various post-mining sites from the close surrounding. This diploma thesis deals with the species composition in post-mining sites and the surrounding habitats up to the 1 km distance from the locality. The results indicate, that basalt quarries share the largest amount of species with their surrounding habitats. The studied methods have got limited capability to predict the species composition of post-mining sites using only the knowledge about habitat types occurred in the surrounding. On the other hand, species composition of the surrounding habitats, defined by a selection of the representative relevés of the Czech National Phytosociological Database (CNFD), seems to be more promising approach. It could provide more precise results applied in ecological restoration of post-mining sites in the Czech Republic.
Autecology of Slow worm (\kur{Anguis fragilis}) in agricultural landsape.
MRÁZ, Roman
The main subject of my thesis is concerning an autecology slow worm (Anguis fragilis) in the countryside, on elaboration of achieved knowledge about ecology of this species in europe and on characterization of places of occurrence in the chosen localities. This work also summarizes knowledge about trapping methods and an idividual diagnostis.
The comparison of ecological and functional characteristics of species Lathyrus niger in rich species meadows and in deciduous forests of White Carpathian Mountains: analysis of growth and assesment of carbohydrate storage by method of liquid chromatography
KLEČKOVÁ, Hana
Lathyrus niger is a persistent herb typical for deciduous forests, which produced a lot of biomass, especially under ground. The aim of this study was evaluation of dynamism of total nonstructural carbohydrates (TNC) in roots and analysis of growth in species L. niger during vegetation season. It was tested influence of biotope (forest or meadow), including influence of shading plants in forest, next influence of mowing on plant{\crq}s growth and on change of content of TNC.
Spatial and flight activity of the maternity colony of the Mediterranean horsheshoe bat Rhinolophus euryale in Slovak Karst
Jehličková, Veronika ; Benda, Petr (advisor) ; Kaňuch, Peter (referee)
In the pre-lacation, lactation and post-lactation periods in 2010 and 2011 and the pre-lactation period in 2012 we used radio-telemetry to determine changes in home range and habitat activity and preference of the maternity colony of the Mediterranean horseshoe bat (Rhinolophus euryale) in Slovak Karst. The colony roosted in the attic of the monastery in Jasov. This area represents the northern margin of the species distribution range. In total, we tagged 35 females that were radio-tracked for 31 nights. For the all pre- lactation periods 17 females were marked, in the lactation periods 12 females were marked, and 6 females were marked in the post-lactation periods. The females were marked with radiotags and the VHF telemetry (radio telemetry using very high frequencies) was used. We compared the spatial and habitat preferences in the above defined seasons of the annual reproductive cycle. The total number of recorded locations was 858 for all reported periods. We compared the varios aspects of activity of the females during the night in the particular periods. We have shown that the females left their roost in the pre-lactation periods as the most late. These were followed by the females in the lactation periods and as the most early after the sunsetthe roost was left by the females in the...
Multifunctional garden ponds and reservoirs
Kraváček, Václav ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The bachelor's thesis deals with the issue of garden ponds and reservoirs with a focus not only on technical design, but also on long-term maintenance of water quality. The main part of the work is devoted to a more detailed description of materials intended for the construction of garden ponds, technical equipment, or the arrangement of individual zones in the pond. Furthermore, the work deals with a detailed description, parameters and character of selected types of reservoirs, such as ponds intended for fish farming, or natural bathing habitats. Last but not least, the work is conceived as a literary search of fundamental knowledge in the field of implementation of garden ponds and their maintenance. The theoretical knowledge is followed by the second part of the work, focused on the design of two variants of the design of a garden pond for a selected investor.
Identification of retention volumes in Brno
Man, Radim ; Roth, Tomáš (referee) ; Jandora, Jan (advisor)
The aim of the diploma thesis is to assess whether it is possible to use a newly planned transverse structures as a polder dam in the area of interest and to connect other flood protection elements. Furthermore, to design and dimension inflow and outflow objects to reduce the flow in the Svratka river as effectively as possible during the culmination of the flood. The last part of the work is devoted to the evaluation of the economic efficiency of the implemented measures. Part of the work are hydrotechnical calculations of the inlet and outlet object, which are performed using the program HEC-RAS and technical drawings of buildings.
Dexterity, or build your house
Netrefová, Klára ; MA, Klára Zahradníčková, (referee) ; Kristek, Jan (advisor)
The design of anthropoid / metamorphosis loosely follows the pre-diploma project Fortel or so called "build a house" when I decided to "put my hand to the work, cut, drill, fold…" and to rediscover the imprints of work and tools in the mass from which they disappeared due to the mass production. The output of the project was an eclectic, crumbling garden of prefabricated bricks. Capillary (open) porosity usually occurs in brick products. It allows the penetration and retention of a relatively large amount of water. The bricks are made of natural mineral raw materials, as well as expanded clay, which is commonly used as a hydroponic substrate. At the same time, the porosity of the brick blocks causes future degradation of the material in the exterior. The disrupted "worked" ceramic blocks in the garden burst, mix with the substrate and create a breeding ground for plants. In my diploma thesis I move away from materials formed into modules, imported to the construction site, and I deal with matter in its freest fluid form and forms arising in-situ. The work is permeated by three fluid media, water, clay and concrete. Concrete - initially a fluid material, takes the form of two other materials, solidifies. Clay - as a semi-solid - semi-fluid material Water - infinitely fluid material, still present, rapidly transforms, and periodically comes and disappears, transforms the other two materials. The materials mix together, form into matter, then drain and disintegrate and disappear when their time comes. With these nature-friendly processes, the design works on three scales. On a micro scale, matter decomposes into gravel, sand, loess, which nourishes soils and plants, and allows an environment suitable for a variety of animals. In the middle scale, these are small objects that shape and manipulate the landscape. And in a big scale, it is co-working with the landscape itself.
