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.
The Occurrence and Biotope Preferences of Selected Amphibians on Abandoned Training-ground in České Budějovice
BOXANOVÁ, Silvie
The aim of this work is to find actual occurrence pattern and biotope preferens for selected amphibian species on the former military training-ground near České Budějovice town and compare the results whit existing ones from previous research thirteen yars ago.
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.
Floristic research of the Studenský creek and Lipnický creek basin at Studená (Javořická highlands)
HARTMANNOVÁ, Pavla
The thesis deals with the floristic research of the catchments of the Studenský brook and the upper reaches of the Lipnický brook. It is focused on natural biotopes, primarily on the wetland habitats. The aim is the characteristic of the biotopes, the complete list of higher plant species and the occurrence of protected, endangered and otherwise important plant species.

Beetle assamblages on the monitoring plots of the Boubín massive in the Bohemian Forest and perspectives of long term monitoring of biotopes state
Boháč, Jaroslav ; Matějíček, J.
In 2003 the investigation of beetle fauna by pitfall traping, sifting and individual sampling was carried out in the area of the Boubín Mt. in the Bohemian Forest. During investigation , 98 beetle species were recovered. Forest species prevail in beetle communities (63%),the frequency of ubiquitous species was lower (24%).
