Vegetation of Otava{\crq}s flood-plain between Strakonice and Písek
LEŠÁKOVÁ, Jana
The thesis is a result of a 2-year floristic mapping (vegetation seasons 2007 and 2008) of basin of river Otava in the sector Strakonice {--} Zátavský most near Hradiště. The thesis includes characteristic of various vegetation biotopes, phytocoenosic recording, a short description and evaluation of distinctive species occurrence. A characteristic of area of interest geomorphologic, geologic, hydrologic, soil, climatic and other conditions) is provided in the form of a literary recherche.

Erebia epiphron in Krkonoše mountains - biotope preference
BAĎUROVÁ, Gabriela
Erebia epiphron was introduced by the German naturalist Joseph Soffner between 1932 and 1933 to the Giant Mts. The species was originally in the Czech Republic distributed only in the Hruby Jesenik. The introduction was successful and today is the introduced population as big as the original, in Jesenik. The goal of my study was to describe the habitat where Erebia epiphron occurs, and to compare the changes between the situation 2008 and previous surveys. I found that the most common habitat on which this buttelfly occurs is the mountain ridge above the tree line with unmanaged meadows (approximately from 1300 m), however, this species can also descend below the tree line. I found this species to be quite common at the sites of its original introduction. The results showed that the population of Erebia epiphron is large and stable.

The occurrence and biotope preferences of amphibians in former military area near České Budějovice.
NĚMEC, Stanislav
Submitted bachelor thesis deals with biotope preferences of amphibians. Experimental part of my work was carried out at former military tank ground near České Budějovice from March until June 2010. Biotope preferences were examined at these species: European Fire-bellied Toad, European tree frog, Agile Frog and Common toad. Since the end of military activity in 1990, there has been growing ecological succession which influences each of the species. The aim of my work was to find out what factors have influence on particular species and compare the outcomes with those of previous works carried out between 1995 and 2008. The observation was pursued during the daytime, above all at night, when frogs are most active. The outcomes has been statistically evaluated and it was found out that great pond surfaces are the most suitable for European tree frog and Common toad, whereas European Fire-bellied Toad and Agile Frog do not mind gradual growth of vegetation, moreover it suits them. The data from 1995 indicate appearance of European tree frog also in pools. My outcomes from 2010 confirmed their appearance only in ponds. On the contrary, Agile Frog has been seen here recently only seldom, in 2010 together with European Fire-bellied Toad it was the most common species. Common toad was the most precious species in the examined habitat. It was found only a few specimens. Appearance of Common toad was registered in ponds in 1995 but this was not confirmed in 2010.

Surveying of the \kur{I. glandulifera} and \kur{I. parviflora} occurrence on the chosen section of Želivka river.
URBAN, Miroslav
The aim of the study was to write a review of research literature on the invasion and in parallel to carry out research work on the subject myself. In the study I chose to focus two species of the genus Impatiens, namely I. glandulifera and I. parviflora. Then I chose a 7 km long stretch of the river Želivka in the Czech-Bohemian highlands to study and survey the population of these two species and plant association. Consequently I focused my study on the river biotope and the role of invasive species in it. It is known, that I. glandulifera and I. parviflora are invasive species which tends to cause disruption to native biotopes. The former forms homogenous arrays near river banks, the latter forms this arrays in forests. In my study I examined the following questions: a) Do river and brook plant association differ in species? b) Which species are correlated with I. glandulifera and I. parviflora and which composition species occur most frequently with the subject species? c) Have different level of shading any impact on species composition? I tested these hypotheses using Statistica 8 (Statsoft Inc. 2007) and CANOCO (ter Braak and Šmilauer 2002) programs. The conclusion is that river and brook plant association differ in species composition. River plant association is lower in plant diversity (Shannon-Wiener index is 0,7; Z = -2,82208, p = 0,004772). Species correlated with I. glandulifera and I. parviflora are detailed on Fig. 7., 8., 9., and 12. The last finding was that different level of shading have impact on species composition in river and brook plant association (Z - Tab. 6, p = 0,0002).

Characteristic of brook lamprey \kur{(Lampetra planeri)} habitats in the Malše River catchment
HLAVÍNOVÁ, Lenka
The aim of the present diploma thesis was to prove the habitation of brook lamprey near Dolní Dvořiště. Biotopes with habitat preferences of brook lamprey were described. During the ichtological investigation of the catchment area of the Malše river in the years 2007 - 2008, brook lamprey was successfully located on sites in Dolní Dvořiště and near Všeměřický quarry. The sites had the same character as trout streams. Length -frequency distribution of the brook lamprey larvae was executed. The species assemblage of ichtofauna of the sites with brook lamprey habitation was described. In the years 2008-2009 other possible biotopes were mapped in connection to the sites in Malše and Tichá where brook lamprey had been located before.

Flora and vegetation of special protected areas at west Bohemian part of southwestern "Brdy" mountains
REISEROVÁ, Alena
Five specially protected areas are situated in the southwestern part of the Brdy region. There are two national natural monuments - Hořehledy and Míšovské Buky and three nature reserves - Chynínské buky, Fajmanovy skály & Klenky and Kokšín. Inventory surveys of vegetation were completed in these areas in 1981 and 1982 (J. Nesvadbová). The next inventory survey of the national natural monument Hořehledy was realize in 1990 two years before the establishing this territory as protected area and others in 2005 due to a proposed change of the area border. In addition, the inventory surveys of all mentioned protected areas addressed L. Šmahel in his work in 1998 - 2000. This bachelor thesis surveys higher plant species in each of the specially protected area and provides a comparison of results with the published works.
