Diploma thesis is focused on data evaluation of economic efficiency of provisions for impoving of water quality in Macha's lake. Data estimation of economic value of chase in water quality in Macha's lake were acquired during on-site research in the area. Choice Experiment was used for modelling of recreational demand. The base of Choice Experiment is coming out from Lancaster's Attribution theory and Random utility function. Data presentation and its acquiring is a part of the diploma thesis, there is also discussed the new findings and the base of neoclassical methodology of Cost-Benefit Analysis that is suitable for judging of economic efficiency of provisions that help improving water quality in The Macha's lake. Macha's lake is a signifiant recreational area. While deciding about long term solution of the problem of water quality it is necessary to judge efficiency of invested ressources. Estimations of changes in water quality in Macha's lake is going to be used for Cost-Benefit Analysis. Cost-Benefit Analysis is based on measuring costs and benefits and their comparisons and this Analysis is main scope of the thesis.

The final stadial of the last glacial - Younger Dryas (12 650 - 11 500 cal yr BP) is relatively well described in sediments of European lakes, however research related to its progress in Central European area is missing. The goal of this thesis was to examine progress of this stadial based on sediment core from Černé Lake at Šumava (Czech Republic). To reconstruct climatic conditions, sub-fossil remains of Chironomidae was used. The air July temperature was estimated using Swiss-Norwegian model. Geochemical analysis was performed to determine intensity of erosion, trophic status of the lake, and sources of its organic matter. To complete information about catchment, pollen analysis was performed. Following climatic events were identified in the sediment: Older Dryas (13 583 - 13 394 cal yr BP), Alleröd (13 394 - 12 383 cal yr BP), Younger Dryas (12 383 - 11 394 cal yr BP) a Early Holocene (11 394 - 11 138 cal yr BP). Presence of two phases of Younger Dryas was not significantly proven, nevertheless, the isotope composition suggests, that the first half of this oscillation was drier. Reconstructed temperature ranged between 8,30 and 10,31řC. The mean temperature for Older Dryas event was 8,92 řC, for Alleröd 9,61 řC, Younger Dryas 9,17 řC and Early Holocene 10,00 řC. Reconstructed temperature...

The main aim of this study was added and verified metodology, analysis of quality and quantity coastal vegetation, considering experience about my previous bachelor´s work and with help pictorial analysis. The ekotonal vegetation were analysed at 9 km long section of coastline, included three sandy-gravel lake (Cep II., Tušť a Františkov). Pictorial analysis, photographs about coastline, was refilled in fytocenology snapshots. Pursuase of this study were discussed influences of cause succession coastal vegetation, species variety and utility of method analysis of pictorial to evaluace vegetation.

In the context of changing climate retreat of mountain glaciers occurs at many places on the planet. One of the consequences is emergence or increase of the outburst risk at lakes situated in front of the glacier terminus. Flood caused by the glacial lake outburst often appear suddenly and can threaten settlements in lower parts of a valley. In the Kyrgyz mountains of Tien Shan there are about 350 lakes at risk of outburst, long-term monitored and dangerous locations are presented in this work. The highest attention is paid to Adygine area where several lakes of different genetic type and age can be found. The largest lake of the locality, the Upper Adygine lake, is subjected to more detailed survey aiming to asses its hydrological regime and to confirm or disprove speculation about outburst possibility of this lake. Keywords: glacial lake, hydrological regime, glacier retreat, Tien Shan, Kyrgyzstan

5 ABSTRACT Long-term paleoenvironmental reconstructions provides essential interpretation of environmental changes. Multiproxy analysis of lake sediments can be used for tracking the historical evolution of lakes and significant processes which formed them over time. Subfossil Cladocera play a key ecological role in freshwater ecosystems. Sedimentary cladoceran assemblages reflect environmental changes and exhibit great potential in past environmental reconstructions. The purpose of this diploma thesis is to identify climatic changes of the time interval between the Late Glacial and the early Holocene in Černé Lake. Based on the analysis of geochemical and biological proxies, determined climatic conditions of Younger Dryas (YD). The YD oscillation in Central Europe has only been briefly described. The Czech Republic is positioned between oceanic and continental climate. The results of the multiproxy analyses suggests that climate conditions of the region during YD were similar to Western Europe with moderate wet climate conditions during the first half and drier conditions during the second half of the period. In the middle of YD there was an interesting event. Observed, probably due to high precipitation and floods. These results are based on P/L ratio, geochemical proxies, pollen analyses and record of...

The Odlezelské Lake is a natural, landslide-dammed lake in western Bohemia. Its lake basin is silting intensely and its volume decreases; it will be completely silted in the future. This work aims to evaluate the siltation of the lake primarily by evaluating the suspended load regime of its tributaries and comparison with data from bathymetric measurements. Within this work, data from the station network of the Department of Physical Geography of the Faculty of Science of the Charles University were used, which was statistically processed in order to describe the hydrological and suspended load regime. In addition, flow speeds in the inflow part of the lake were measured during two precipitation-runoff events using ADCP. The results show that most of the suspended load is transported during flood episodes, in contrast to the runoff, there is a significant interannual variability in the suspended load regime. Oppositely, the comparison of the suspended load regime and the bathymetric data proved as impossible due to a high sensitivity of the data.

Komořany Lake, regarded as one of the most important sites of the Czechoslovak Quaternary, was situated at the southern foot of the Krušné hory Mountains, northwest from the Starý Most town, between the villages of Souš, Komořany, Ervěnice, Dřínov, Albrechtice, Černice and Dolní Jiřetín. Due to its size, Komořany Lake belonged to the largest bodies of water in the Czechoslovak Republic (25 km2 ) and due to the quantity of organogenic sediments get into the focus of paleoecologists. Gyttji sediments which occupy comparatively thick position in the lake infilling, formed a continuous record from the Last Glacial period to the Subatlantic period and up to now have been processed mainly from the paleoecological point of view. In this work the organogenic sediments are studied from the sedimentary record using modern geochemical methods (TOC/TN and d13C) for the first time in Komořany Lake history. The work was based on profiles (PK-1-C, PK-1-Ch, PK-1-I and PK-1-W) which were taken between 1977-1983 before a complete exploitation of Komořany Lake sediments as a result of coal mining in the Most Basin in the 1980's.

Nowadays the evolution of civilization gives us the opportunity to have more and more free time and fun is taken as just like one of the opportunities how time can be used. Architecture going to be only a tool for developing and promoting business within amusement parks. But how does entertainment affect us? Do we need have fun? And what else can give a person a symbiosis of joy and architecture? The aim of this work is to analyze the problem of relations between fun and architecture and suggest a solution in a specific architectural intention.

<p><em>Natrix tessellata </em>predstavlja vrstu neotrovne zmije koja ima &scaron;iroko rasprostranjenje.<br />Posebno interesantnu populaciju ribarica čine zmije koje naseljavaju izolovana ostrva kao &scaron;to je to slučaj na ostrvu Golem grad koje se nalazi na Prespankom jezeru u Makedoniji.</p><p>&nbsp;&nbsp;&nbsp; Imajući u&nbsp; vidu da je ova populacija na ovom lokalitetu izuzetno brojna i slabo istražena, cilj studije je bio da se ispita životna istorija date vrste zmija, njene osnovne morfolo&scaron;ke karakteristike, seksualni polimorfizam, zastupljenost različitih kolor morfi, dnevnu i sezonsku aktivnost, predaciju kao i njihove reproduktivne karakteristike.</p><p>&nbsp;&nbsp; Studija je sprovedena na ukupno 3850 jedinki ribarica na ostrvu Golem grad tokom prolećne i letnje sezone u periodu od 2008. do 2012. godine, a uključila je i određivanje kondicionog indeksa i njegovu vezu sa kolor morfama, polom i uzrasnim kategorijama.&nbsp;&nbsp;&nbsp;</p><p>&nbsp;&nbsp; Rezultati ove studije su pokazali da je populacija ribarica koja naseljava ostrvo Golem grad, specifična iz nekoliko razloga. Najpre, na relativno malom prostoru stalno je naseljen veliki broj jedinki, sa podjednakom zastupljeno&scaron;ću sve tri kolor morfe (tačkasta, siva i melanična kolor morfa) &scaron;to predstavlja specifičnost i različitost u odnosu na sve ostale lokalitete koje naseljava ova vrsta zmije. Takođe, prosečne vrednosti ispitivanih morfolo&scaron;kih karakteristika ženki su značajno veće u odnosu na mužjake u sve tri uzrasne kategorije (juvenilni, subadulti i adulti). Fertilitet i fekunditet, kao i kondicioni indeks je pokazao specifičnost u odnosu na ispitivane zone ostrva.</p><p>&nbsp;&nbsp; Sumiranjem i analizom svih iznesenih rezultata može se zaključiti da je populacija<br />ribarica <em>Natrix tessellata</em> na ostrvu Golem grad jako specifična zbog ujednačenog prisustva sve tri kolor morfe koje pokazuju svoju ekolo&scaron;ku, reproduktivnu i morfolo&scaron;ku specifičnost u odnosu na populacije ribarica koje su ispitivane na drugim lokalitetima njihovog rasprostranjenja. Kako bi se posebnost ove populacije u potpunosti&nbsp; objasnila sa različitih evolutivnih i ekolo&scaron;kih aspekata, neophodno je izvr&scaron;iti dalja ispitivanja tokom sledećih aktivnih sezona.</p> / <p><em>Natrix tessellata</em> represents one specific type of non-toxic snake that have a wide distribution. Particularly this population of dice snake is interesting because it is consists of snakes that inhabit the isolated island Golem grad in Prespa lake in FYR Macedonia.</p><p>Bearing in mind that this population at this particular site is extremely dense and poorly investigated, the goal of this study was to examine the life history of these species, its morphological characteristics, sexual polymorphism, presence of the&nbsp; different color morphs, duirnal and seasonal activity, predation and their&nbsp; reproductive &nbsp; characteristics. The study was conducted on a total of 3850 individuals of dice snake on the island Golem grad during the spring and summer season in the period from 2008. to 2012., and included the determination of the fitness index and its relationship with a color morph, sex and age categories.&nbsp;</p><p>Results of this study showed that the population of dice snakes that inhabits the island Golem grad, are specific for several reasons. First, the relatively small area has been inhabited by large number of individuals, with equal representation of all three color morphs&nbsp; (dotted, gray and melanic morph) which represents the specificity&nbsp; and diversity in relation to all other localities inhabited by this species of snake. Also, the average value of measured morphological characteristics in females&nbsp; were significantly higher than in males in all three age categories (juvenile, subadult and adult). Fertility and fecundity, and fitness index have showed the specificity acording to specific zone of the island.&nbsp;</p><p>&nbsp;&nbsp; By summarizing and analyzing of results it can be conclude that the population of <em>Natrix tessellata</em> which inhabits island Golem grad are very specific due to the uniform presence of all three color morphs that demonstrate their&nbsp; environmental, reproductive and morphological specificity in comparison of dice snakes populations that have been studied in other localities of their distribution range. In order to be fully explained unicity of this population from different&nbsp; evolutionary and ecological aspects, it is necessary to do further research during the next active seasons.</p>
