Invasive fish species in the Czech Republic
Lusk, Stanislav ; Lusková, Věra
In the Czech Republic, the following fish species are evaluated as invasive: Carassius auratus, a species showing a significantly negative influence on the occurrence of native species Carassius carassius and Tinca tinca in natural habitats. Certain manifestations and properties (such as the invasive way of dispersal, numerous populations, great ecological tolerance etc.) typical of invasive species can also be seen in Pseudorasbora parva, Ameiurus nebulosus, and Proterorhinus marmoratus. In some of its manifestations, even Cteropharyngodon idella can affect biodiversity in a negative way. One cannot exclude the future invasion or introduction of any alien species evaluated as invasive, particularly those of the genus Neogobius that occur in the Slovakian part of the Danube, and Perccottus glenii that has already invaded the Tisza River drainage area and the lower part of the Danube.

Participative management – key to minimaze conflicts between protection of biodiversity and socio-economic development of local communities
Těšitel, Jan ; Kušová, Drahomíra ; Matějka, K. ; Boháč, J. ; Bartoš, Michael ; Kopáčková, M. ; Moravcová, Jana ; Šrubař, Vladan
The project was aimed to propose a model of optimal coexistence of biodiversity protection and socio-economic development in large-scale protected areas. Its main output was identification of principles of participative management of protected areas and estimation of circumstances necessary for its practical implementation. The project focused on description of biodiversity in particular model areas, on eventuality of changes in biodiversity due to human activities and thus on identification of actual and potential conflicts. In parallel, selected parameters of quality of life of local population, behaviour the population and its relation to the Administration of protected area and to nature protection in general were studied. Analysis of behaviour of the administration of protected areas as social institution became also part of the project. The project was designed as empirical comparative study of three biosphere reserves (BR) - BR Šumava, BR Třeboňsko a BR Křivoklátsko.

Amenitní migrace a turismus
Bartoš, Michael ; Kušová, Drahomíra ; Těšitel, Jan
Amenity migration is new global phenomena. It is a specific type of migration which is not motivated by economic prosperity – it has been brought about by the desire to render more valuable natural or socio-cultural environment of the target territory, and it exists from metropolitan to rural areas. This phenomenon has been strongly supported by the spread of mass information technologies and. Under specific conditions it can become one of societal driving forces determining the socio-economic development of the given region. It seems that tourism play crucial role in formation of amenity migration. It precedes amenity migration being, as a rule, regarded its initial form.

Current status of nature protection and management in Lužnice floodplain
Montagová, Martina ; Pithart, David
Lužnice floodplain has been preserved in a semi-natural state in a cca 25 km long section located between the state border and the town of Suchdol n L. Meandering river is surrounded by pools and oxbows, which are flooded several timeas a year. Most of the area is now the subject of nature protection. Microorganisms (Algae), water plants, birds and other wetland biota found a refungium here. Biodiversivity is maintained by river activity and mosaic structure of the landscape, formed by e pastures and wet forests. This character of landscape is now endangered by ceasing of meadow management, hence, the large parts of floodplain are now under the succesional stages leading to the wet forest in the decrease of overall biodiversity.

Route Mapping for Wheelchair Users in Protected Landscape Area Broumovsko
Gürtlerová, Jana ; Ortová, Marie (advisor) ; Pařízek, Michal (referee)
This work deals with accessibility of nature sites for the handicapped people, particularly wheelchair users. It informs about the accessibility of protected landscape areas and national parks in the Czech Republic. The legislative frame of the system of tourism for wheelchair users is still insufficient. Thanks to a few organizations and individuals, several handicapped-accessible nature trails were developed. The aim of this work is to map current possibilities of visiting the Protected Landscape Area Broumovsko on a wheelchair. Although the terrain of the area is rather difficult to acces, it was possible to create six new trails through this countryside. The tracks are suitable for wheelchair users in mechanical wheelchair with company. Five of these tracks lead through the area of Broumov's rocks and last track shows a part of the Adršpach Rock Town. The trails vary from three to six kilometers of length and they mostly covered with tarmac. One of the aims of the thesis is to produce an information leaflet monitoring routes for wheelchair users. In addition, it provides a detailed description of the routes on web sites of the Local Authority of CHKO Broumovsko and a few wheelchair users' organisations. The text of a leaflet containts information about accommodation and refreshment facilities for...

History of vegetational development in the Cheb basin from sedimentary record of the SOOS National Nature Reserve
Suda, Tomáš ; Kuneš, Petr (advisor) ; Bešta, Tomáš (referee)
Vegetation development in the Cheb basin ( W Czech Republic) recorded in the sediments of the SOOS ational ature Reserve This thesis focuses on palaeoecological research of quaternary sediments in the Soos National Nature Reserve (Cheb basin, NW Czech Republic). Quaternary history of this locality is poorly known, despite it is a valuable and protected area with high natural qualities. The Soos basin is also known for its unique geological record, which is expected to cover information on landscape dynamics at least during the Holocene. A lake existed in the Soos basin enabling accumulation of diatomite and peat sediments of a broad palaeoecological potential. Records were analysed with method of pollen analysis and were dated using 14C. The results of this study bring information about vegetation development in the area of Cheb basin as well as development of lake ecosystem. It also gives a new insight on lake's origin and its age. The accumulation of peat sediments started in the Preboreal period and was continuous at least until the Atlantic following with a hiatus, therefore further detection of vegetation development is impossible. The beginning of diatomite accumulation, as well as the existence of the lake goes back to the Bølling interstadial, according to radiocarbon dating. However, this...

Effects of Spirulina platensis on the expression of endothelial NO synthase in apoE-deficient mouse model of atherosclerosis
Pešlová, Monika ; Nachtigal, Petr (advisor) ; Kopecký, Martin (referee)
1. ABSTRACT Spirulina platensis is a blue-green microalga belonging to the cyanobacteria family. Microalga is a large source of proteins and good fatty acid and other nutritional elements, for example iron, calcium, chromium, lithium, selenium. It also contains natural dyes chlorophyll, phycocyanin. Its antioxidant and anti-inflammatory were described. The aim of this thesis was to determine potencial hypolipidemic effects and potential effects on endothelium of Spirulina platensis in apoE-deficient mice. ApoE-deficient mice were fed standard diet for 2 weeks. At the age of 8 weeks the control group of animals were fed with the western type diet, which contained 21% fat and 0,15% cholesterol for 8 weeks. The same atherogenic diet was used in Spirulina platensis group, where Spirulina platensis was added to the atherogenic diet at the dosage of 20 mg per day. The biochemical analysis of lipid spectrum was done, area of atherosclerotic lesions was determined and imunohistochemical and stereological analysis of eNOS expression was performed as well. The results of this thesis showed positive effects of Spirulina platensis on cholesterol levels, VLDL and LDL cholesterol. Moreover stereological analysis of imunohischemical staining revealed that, that endotelial expression eNOS was significantly increased by...

The Role of Nurses in Colorectal Surgeries
ŠULCOVÁ, Jana
Theoretical basis: The problems in rectal and anal diseases have had rising tendency, especially haemorrhoidal diseases, on which we put emphasis in our bachelor thesis. 37% of adult population suffers from this disease so we may line it up to civilization illnesses. Their treatment involves wide range of medical methods, from the conservative therapy to semi invasive ways of treatment. The semi invasive treatment is well withstood by patients and it can help up to 90% of clients. This bachelor thesis is concerned with specifics of nursing duties in a colorectal surgery. It links with topics like taking faecal specimen, basic methods of endoscopy, communication with patients and giving them information about lifestyle. The theoretical basis describes haemorrhoidal disease and gives brief introduction into causes of its developing, most common symptoms and possible treatments. The aim of the thesis: From the practical point of view we set two tasks. The first one is aimed at specifics of nursing job in a colorectal surgery and the second one tries to monitor how nurses in colorectal surgeries inform patients about healthy lifestyle. We asked two research questions regarding these aims. The first research question is: What are the specifics of the nursing job in the colorectal surgery? The second question concerns how nurses in colorectal surgeries provide information to their patients about healthy lifestyle. Methodology: Regarding the bachelor thesis we decided to choose a form of a qualitative research with using semi structural interviews with practical nurses working in colorectal surgeries. The interviews took place from February 28 2014 to March 15 2014 in five colorectal surgeries in following towns: České Budějovice, Písek, Strakonice, Jindřichův Hradec a Třemošná u Plzně. The focus group was created of 6 nurses working in colorectal surgeries. The interviews were performed and recorded with the consent of all practical nurses involved in the research. All extracted data was arranged and categorised into groups that were consequently analysed. The interviewer´s questions were prepared in advance and some extra questions were asked during the interview. The interview was divided into five areas: Identification questions, role of a nurse, examination methods, recommendation and giving information about lifestyle. Results: The results show the specifics of nursing in colorectal surgeries. We found out that nurses working in colorectal surgeries deal mainly with preparing special medical instruments and devices needed for endoscopic examination. Then they assist doctors during a medical examination and with treatment methods of RBL (Barron´s rubber band ligation) and Hemoron, they manipulate with devices in a surgery, check hygiene measures, do administrative work and keep surgery office running. In other conversation areas practical nurses mostly mentioned sampling of biological materials, mainly blood and faecal specimen taking to be given up to histological examination, preparing patients for an endoscopic exam, communication with patients and attending to the intimacy of patients. Consequently we found out that more than half of the practical nurses pay attention to psychological conditioning of the patient before rectoscopy. The research also revealed some weak spots. More than half of the nurses in the focus group do not inform patients about preparations before anoscope exam. Barely one third of the group said that they inform patients about the natural emptying before the exam. Regarding the issue of giving information about lifestyle, we came to the conclusion that practical nurses, even though they do not have enough time, try to inform patients about physical activities, hygiene care and quality of eating and they do it in sufficient rate. But because of the time constrain they put emphasis only on the essential information.

Documentation of the nature reserve Miletinska bazantnice (Czech Republic)
Stejskalová, Klára ; Skalický, Milan (advisor) ; Martinková, Jaroslava (referee)
The aim of this study is to document the floristic species diversity through research in the natural reserve Miletinska bazantnice. Documentation was carried out on the territory concerned during the growing season of 2015. There was a determination of vascular species. The research was mainly focused on endangered and protected species.
The whole area is part of sites of European importance under the Habitats Directive Natura 2000 Miletinska bazantnice was declared a nature reserve in 1954 with an area of 75, 43 hectares and is part of a small-scale specially protected area. Typical features of the area are remnants of natural Podzvicinsko geobiocenosis and therefore the reason for its protection.
Further it describes the history, characteristics of the territory and the natural conditions that are typical for the locality. These include soil science, climate, hydrological, geomorphological, geological and phytogeographical. On the territory of the nature reserve are recorded two memorial trees. It´s oaks (Quercus robur) called Zizkovy duby.
At present territories were found in protected and endangered species and classified under the Red and black list of vascular plants of the Czech Republic (Grulich, 2012) and Decree of the Ministry of Environment of the Czech Republic no. 395/1992 Coll. Into the category of rare taxa that require additional attention include species such as Carex otrubae, Cerastium lucorum, Daphne mezereum, Galium boreale, Listera ovata and Primula veris. The only species Platanthera bifolia is ranked in the category of endangered under both the Red and black list of vascular plants in the Czech Republic and under Decree.
In the field survey, attention was also paid to invasive species, sorted by Catalogue of alien plants of the Czech Republic (Pyšek et al., 2012) and categorized archeophytes (Arctium tomentosum, Cirsium arvense, Convolvulus arvensis, Chelidonium majus)
and neophytes (Arrhenatherum elatius, Impatiens parviflora) and described their risks (Mlíkovský and Stýblo, 2006)
