Genetic markers in the evaluation of diversity
PITROVÁ, Ludmila
A major purpose of this study was to summarize the information on the biodiversity and genetic variability on the earth and about factors affecting the diversity. There are more details about genetic origins of farm animals with focus on horse, namely Old Kladruber horses as a Czech cultural monument. This breed is illustrative living example how to use genetic information for breeding and for conservation of the species.

Age diversity - promoting equal opportunities in RWE
Procházková, Petra ; Němec, Otakar (advisor) ; Ondřej, Lukáš (referee)
The topic of the thesis entitled "Age diversity - promoting equal opportunities in RWE" is an analysis of diversity management tools specific to the company from 2011 to 2012, defining age management and proposing an action plan of age diversity in the company for the years 2013 and 2014. The theoretical part of the thesis defines the basic concepts needed to deal with the issues such as equal opportunities, diversity, age management. The thesis includes a description of the historical development of diversity management, including the legislative framework in the EU and the Czech Republic. Age management is the management with regard to the age and abilities of employees and, as such, is clearly related to demographic changes of society. The thesis summarizes the forecasts of demographic development provided by ČSÚ, indicating that the demographic situation in the Czech Republic leads to the aging of population. In the practical part of the thesis is an analysis of the project "Diversity" of RWE Group on 31 December 2012, particularly with regard to the application of tools for age diversity, analysis of diversity of the labor force, and the definition of a job potential. Analysis results are compared with those of selected companies in age management. Based on the findings an action plan of age diversity of the RWE Group for next period is designed. The aim of the thesis is to verify the positive benefits of age diversity for the RWE Group in the Czech Republic.

Ichthyologic monitoring the flow of Popelka in Nová Ves nad Popelkou
ZELENKA, Václav
The aim of this work is to evaluate ichtyofauna in the stream Popelka, to determine the species composition of fish stoce and to determine the dominant fish species, their abundance and size variability. Throughout the length of the flow, twelve catching sites were identified there, the length of each site was about 50 m, the catch in these sites was from the bottom of the upstream towards the end. The catch of the flow was by wade manner with use of an electric aggregate. All caught fish species were subsequently determined. Also the body lenght so-called ?standart lenght? was measured. After measuring all fish that were caught were gently given back to the place of the catch. In terms of abundance the most numerous species in Popelka was brown trout represented by 477 subjects followed by stone loach with 391 subjects. These species clearly dominated in Popelka. Another occurring species were rainbow trout with 49 subjects, brook charr with two subjects and hybrid of brown trout and brook charr with one subject. With regard to the regional constance the brown trout was a species almost always present, with presence in 11 out of the 12 sites. Stone loach with incidence in 8 locations was mainly occurring species. With the appearance in 5 localities the rainbow trout was frequently occurring species. Among the species that are rare in Popelka, there were brook charr occurring in two locations and hybrid of brown trout and brook charr with the appearance in one location. Index of species diversity by Shannon and Wiener for the flow of Popelka is 0.88 and evenness is 0.55. Size variability across the flow in body length of brown trout was ranging from 46 to 308 mm, in diameter 126.4 mm, the stone loach from 41 to 130 mm, in diameter 80.1 mm, the rainbow trout from 65 to 250 mm, in diameter 88.7 mm and brook charr from 290 to 313 mm with an average of 301.5 mm. In the Popelka stream with a total length of 12 km there are four species of fish in these fish communities. Species diversity is distinctly poorer in comparison with the other streams. It would be appropriate to repeat the catch in the future to determine the stability of fish population in Popelka stream.

Ichthyofauna of selected sections of the Jizera basin
CHYTRÝ, Martin
Rivers fragmentation by migration barriers has a significant negative effect on native fish communities and other river organisms. That is the reason why there has been put a lot of emphasis on creating fish pass in rivers in recent years. Between the years 2012 and 2013 there were carried out investigations on the new slit fish pass on the Jizera River in Turnov. The aim was to assess the technical realization of the construction of fish pass and functionality for local ichthyofauna. Primarily we have focused on hydraulic conditions in the fish pass (water flow, velocity, level differences in all chambers). During the fish pass technical inspection the fish was being caught by electric aggregate. The species composition of fish was also measured in the weir. Catching weir was used to catch the counter-migrating fish through the fish pass. The caught fish was taken its body length in mm and weight in grams and subsequently was calculated numerical dominance, diversity and evenness. There were 519 pieces of fish caught weighing 6.395 kg in total. There was confirmed presence of 10 species of fish in the fish pass, while in the weir were found 3 more species of fish and 1 species of lamprey. Reproductive migration was confirmed for brown trout and minnow. Roach, dace, perch and chub have settled down in the resting chambers permanently. There have been found several defects in the fish pass. There have been found large differences between the levels of chambers, high flow rates, reduced light penetration of the water in the fish pass, lack of entry attractiveness of the fish pass and non-minimum residual flows. Fish passage is considerably clogged by suspended dirt and the cleaning possibility is limited. Functionality and selectivity of the fish passage has not been demonstrated. There will be further investigations carried out in 2013.

Sustainable approaches to small-area grassland and barren management with respect to flora and insect diversity
Vymyslický, T. ; Fabšičová, Martina ; Musil, Z.
This study is devoted to the determination of sustainable ways of increasing flora and insect diversity in meadows through the establishment of barren sites and fallows, which help many ephemeral plant species to reproduce from the soil seed bank. We tested the optimal time for the duration of a fallow and it seems to be 3-5 years. Significant differences were observed in the number of species and their cover between nutrient-poor and nutrient-rich areas.No massive occurence of invasive and expansive species was found. In the warm eastern part of the Podyjí NP we found plant species that had been missing there for many years.

Diversity of fishpond zooplankton in Javořice highlands region
IŠTOK, Tomáš
It studied the species composition of pond zooplankton selected pond in Javořická highlands, near Nová Bystřice and Slavonice. Sampling was pelagial and at selected locations and littoral ponds. When selecting sites sampled, the emphasis was on the selection of sites with historical, expected or actual occurrence Heterocope saliens that occurs on sites with ponds and bogs around the aquatic environment with lower pH. These sites are usually extensively farmed. Found 69 species (24 Cladocera, 15 Copepoda, 30 Rotatoria). Confirmed the hypothesis that the greatest variety of species of zooplankton found at mesotrophic sites with moderate fisheries management.

Ichtyofauna of selected streams of Bohemian Forest
ŠRÁMEK, Jiří
Presented work is directed to summarize the results of ochtyomonitoring of five stream in Bohemian Forest in autumn 2010. The processing status is evaluated fish communities, especially their species composition, diversity, dominance, evenness and other parameters. They have been evaluated also physico-chemical properties of the sites such as air and water temperature, conductivity and turbidity. Last but not least were evaluated the characteristics of flows and in particular morphological characteristics, types of the bottom substrate and its contours etc. The evaluation of all obtained data showed that fish communities surveyed Bohemian flows are balanced, they are not burdened with invasive species and rand indicators correlated with the state of flow, geographic location and natural conditions. It was caught nine fish species in the total number of 963 individuals. Abundance was at all locations in the range 201,6 to 409,7 individuals per kilometer of flow, showed the diversity of communities from 0,372093 to 2,166085 (Shannon and Wiener index) and from 0,301804 to 0,866948 (Simpson index), then evenness of plant 0,372093 to 0,783906. The most dominant species was the brown trout, the second most frequent species was bullhead.
