Vietnamese integration in the South Bohemian region-case study of České Budějovice
ŠIROKÁ, Michaela
At the beggining the thesis will shortly describe the migration process from Vietnam to the South Bohemian region. Furthermore, it will characterize migration stages of Vietnamese people to the Czech republic and indicate their raising and decreasing amount in the South Bohemian region. The thesis is focused on their economical activities and social status. It will outline the current situation Vietnamese society in the South Bohemian as well. Moreover, the thesis will analyze social work of the centres that help to improve integration process of the Vietnamese people in the South Bohemian region. It will depict the civil and political participation towards the Vietnamese society to the Czech society in the South Bohemian region. It will clarify how many organizations and guilds was founded towards Vietnamese people in the South Bohemian region.

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.

Growth ot tadpole groups - the influence of size and kinship.
SRB, Ondřej
The aim of this study was to determine the effect of density and kinship on the rate of metamorphosis of the selected species of frogs. The work was made in Rana temporaria, common frog. Tadpoles of this species have been bred at different densities kindred subjects. The regular weekly intervals were timed tadpoles until metamorphosis. It has been shown that tadpoles reared individually developed much faster and metamorphosed at larger sizes. Contrast, tadpoles raised in unrelated groups developed much more slowly than in the group composed of related individuals.

Kingfisher (Alcedo athis), an Example of Fulfiling EU Legislation - Nature 2000 in IBA Třeboňsko
HLÁSEK, Oldřich
The population of Common Kingfisher in northen part of Třeboňsko Region was monitored according to the fulfilling of EU directions {--} Natura2000. Between the years 2004 and 2006 105 km of watercourses, water reservoires, sand quarries in the map square 6854 were regularly monitored. Recent population condition was monitored. Technical adjustement of recent, new, and extinct nest walls followed. Thanks to these modifications, the number of successful and perspective breeding places increased. The next step was to check the progress and success of nesting. During other inspections I observed the success of nesting, depending on environmintal conditions, and{--}if needed- I determined the reason why the nest place was destroyed. In the conclusion I suggest practical measures {--} how to adjust nesting places {--} which night result in stabilization of the population.
