Geophysical prospection of volcanic structures, in the area of Rybí loučky, Jizerské mountains
Fait, Václav ; Valenta, Jan (advisor) ; Skácelová, Zuzana (referee)
This thesis briefly depicts fundamental principles of three geophysical methods (gravimetry, magnetometry and electrical resistivity profiling), which had been used during research at the Rybí lou ky site in order to clarify local geological conditions. Furthermore, the reader gets acquainted with formation of a maar-diatreme, which is thought to be present at the researched site. The next part describes principles of field measurements and the procedure for evaluation of results. The results are graphically plotted in the last part. Also, the results are compared to previous investigations conducted at this site. Geophysical measurements showed that geological structures on the Rybí lou ky site are much more complex than expected. The simple diatreme structure is most likely not applicable in this case. In contrast, it is not a structure formed solely by a glacier. The origin is most likely a combination of tectonic predisposition, volcanic activity and subsequent selective erosion.

Rybí společenstvo vybraných toků Jizerských hor
DOLEŽAL, Tomáš
Fish communities of selected streams of the Jizera Mountains The watercourses of the Jizera Mountains have the character of trout and grayling zones, with occurrence of indigenous populations of brown trout (Salmo truta morpha fario) and protected fish species. Fish communities have been disturbed in the past century by an increased degree of acidification of the environment, with the disappearance of native fish species from some localities. Subsequently, the brook trout (Salvelinus fontinalis) was introduced in these localities, and in some of them created sustainable populations capable of natural spawning. At present, in order to improve the environmental status of many localities, efforts to replace these stocks by the indigenous species of fish, brown trout and fathead minnow (Phoxinus phoxinus). The fish populations are also negatively affected by the fragmentation of watercourses and water use associated with the operation of hydropower plants. Attempts are currently being made to allow fish migration by bridging migration barriers by building of fish laddders. The aim of this work was the ichthyological research of the River Smědá. 10 localities on the river were electrofished and 14 fish species were found, of which three belong to the endangered species (Burbot (Lota lota), Bullhead (Cottus gobio), fathead minnow) and one species was non-native (brook trout) Based on a survey basic characteristics of the communities were determined (abundance, dominance, biodiversity and evenness). High species diversity (13 species) and biodiversity (H' 2.38-2.97) were found in the localities under Frýdlant. In the localities above Frýdlant was a lower species diversity (5 species) and biodiversity (H' 0-1.65), due mainly to the nature of the flow, but also influenced by insurmountable barriers, which make fish migration impossible

Civil Society of Jizera Mountains and biosphere reserve. The future prospects of nongovernmental organisations in Jizera Mountains for biosphere reserve.
Chudobová, Andrea ; Rynda, Ivan (advisor) ; Kutáček, Stanislav (referee)
The thesis is based on the idea of extension the Krkonoše/Karkonosze transboundary biosphere reserve by Jizera Mountains territory. Biosphere reserves are established within the Man and the Biosphere Programme of UNESCO. According to the Madrid Action Plan it is necessary for the sake of appropriate functioning of biosphere reserve to involve all the stakeholders, including non-governmental organizations. Using semi-structured interviews with the representatives of the Jizera Mountains non-governmental organizations I therefor asked them about their opinion of the extension of the Krkonoše/Karkonosze transboundary biosphere reserve by this area and their willingness to participate in cooperation within the biosphere reserve as well. I investigated their sustainable development capacity, which in the same time represents their possible contribution to the biosphere reserve. The research shows that non-governmental organizations accepts the idea of the extension of the Krkonoše/Karkonosze transboundary biosphere reserve by Jizera Mountains. Together with it their potential for backing the appropriate functioning of biosphere reserve in this territory was proven.

Nature and Historical Characteristics of the Jizera Mountains
Procházková, Michaela ; Teodoridis, Vasilis (advisor) ; Hlaváčová, Lucie (referee)
This bachelor thesis describes natural relations and history of the Jizera Mountains. First part is focused on geological and geomorphological processes creating the landscape and also on climatic and hydrological aspects. A second part gives an account of flora, which is a little reduced due to poor mineral subsoil. The exceptions are peat-bogs. These ecological subtypes represent the most valuable and the most important biotope of the Jizera Mountains. There we could discover a lot of unique and protected species of plants and animals. A history of the Jizera Mountains mapping here the settlements from prehistory age to modern times is also described in detail. Neither I do not forget to mention a development of textile and glass industry, which are also very important for this region at the field of economics. The deportation of the Germans after 2nd World War was an essential event resulting in almost complete displacement of the Bohemian border region. People have returned to the mountains due to tourism and a phenomenon of "the summer cottage" at 60th and 70th years of 20th century. A question about protection of the most specific comes out with an increasing quantity of visitors in this area. In the last part of the bachelor thesis is focused on this topic. This thesis has especially educational...

Selected Vertebrate Species of the Jizera Mountains in Inquiry Based Science Education at Primary and Secondary Schools
Kršková, Adéla ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
The thesis consists of two main parts: a theoretical one which includes a separate chapter about the Jizera Mountains as a whole, introducing their geological structure, climate, botanical and zoological species and three public figures connected with the Jizera Mountains. The second part is a practical one. The first chapter which is divided into ten sub-chapters, introduces typical vertebrates, especially those which can be included in education at primary schools and grammar schools. The next chapter mentions nature trails which are later suggested as enriching elements in zoological excursions. These must follow the official paths within the nature conservation area. Certain thought in this thesis is also given to the SPA (Special Protection Area) established to protect the black grouse and the boreal owl. The last but one chapter involves selected centres of ecological education and other organisations organising programmes focused on vertebrates. Then there is classification of primary and secondary education with emphasizing a short survey of which biology textbooks are used at primary schools around Jablonec nad Nisou. Education at secondary schools is supplemented with international researches called PISA and TIMSS serving as a base for the last chapter, which is about enquiry based...

Structure of zooplankton in reservoirs of the Jizera Mountains during the peaking anthropogenic acidification and recovery from acidification (1992-2011)
Bímová, Tereza ; Hořická, Zuzana (advisor) ; Seďa, Jaromír (referee)
Acidic atmospheric deposition and acidification of soil and water on the Earth's surface, due to emissions of sulfur and nitrogen into the atmosphere, have led to drastic changes in the composition of surface waters and their biota in many regions of the world over the last century. The number of species and biomass of phytoplankton, zooplankton and benthos were reduced, or some components (zooplankton, zoobenthos, fish) became extinct. In the Jizera Mountains (Northern Bohemia, Czech Republic), the man-made acidification has always been combined with a natural acidity (dystrophy) of waters, caused by a high amount of organic acids. Despite a strong recovery of water chemistry from acidification, that has started in the 1990s, biological recovery is delayed and much more complex. This master thesis is a study of the succession of zooplankton (crustaceans) in mountain reservoirs Souš, Bedřichov and Josefův Důl after decades of strong acidification. Biological recovery from acidification has been in progress differently in the drinking water reservoir Souš, which has long been limed, in the Bedřichov reservoir with naturally high content of organic material, and in the drinking water reservoir Josefův Důl, which is the largest and deepest one and which was most affected by acidification. Recovery of...

Phytoplankton of drinking water reservoirs in the Jizera Mountains, Czech Republic, in relation to treatability of water
Čermáková, Anna ; Hořická, Zuzana (advisor) ; Procházková, Lenka (referee)
The area of the Jizera Mountains (northern Bohemia) was significantly affected by acid atmospheric deposition in the second half of the 20th century. This mountain area has a very sensitive geology and is characterized by the predominance of spruce stands, naturally acidic shallow soils of podzolic type, large areas of peat bogs in the upper plateau, a rough climate, and a very high annual rainfall. The frequent heavy rains and a low infiltration capacity of soils brought about floods in the past, very dangerous for the populated foothills. , so in the early 20th century For that reason, a plan was proposed to construct a system of reservoirs for a flood protection of the area. In the 1970s, the need for new sources of drinking water increased in the area. The Souš retention and recreation reservoir was rebuilt to a drinking water reservoir in 1974, and a new drinking water reservoir Josefův Důl was bulit in 1982. Both the water bodies have had a dystrophic character since the beginning, and the Souš reservoir suffers from naturally high concentrations of aluminum. Due to the anthropogenic acidification, the reservoirs were fishless until brook charr (Salvelinus fontinalis) were successfully (re)introduced in the 1990s, and the diversity and numbers of the zooplankton were very low. The...
