Communities of small terrestrial mammals in the surroundings of Vltava river
ŠPILAUER, Tomáš
The bachelor thesis is dealing with the influence of watercourse on the biodiversity of small terrestrial mammals in landscape near river Vltava in South Bohemia. The theoretical part consists of literally review about diversity, ecotones, biocorridors, watercourses and about ecology of small terrestrial mammals. The aim of the practical part is to compare biodiversity, abundance of small mammals and compare impact of watercourses on small mammals. During 2021 vegetation sesion the CMR method with ear tags was used. During three-days long captures were laid 25 traps in 5 metres distances in each of the three studied biotope lines (Forest, Meadow, Shore). In total 136 individuals of small mammals were captured. The species, sex, weight, foot lenght and age of captured mammals were determined. Two species of small terrestrial mammals were captured (Myodes glareolus, Apodemus sylvaticus). In total of all 136 individuals were captured: 51 individuals of Myodes glareolus and 75 individuals of Apodemus sylvaticus. Significant difference in quantity was in the line Forest where were captured 23 Myodes glareolus and 45 Apodemus sylvaticus. In the line Forest were captured 68 individuals in total and the same number was captured in the line Shore (also 68 individuals). In the Meadow line no individual was captured.

Analysis of landscape changes during the complex landscape management
HEJMAN, Martin
This diploma thesis was written to analyze and evaluate the changes of the landscape in selected cadastral communities with a finished complex landscape management. The analysis was completed in four time periods. It included a historical time period in 1952, a period before the landscape management, a period during the designing of landscape management and the present condition of the landscape. Changes that appeared in the landscape were evaluated for land use, the permanent landscape structure, the density of the road network and ecotones. According to the results of the diploma thesis it is possible to find out how the complex landscape management project for individual studied areas contributed on the progress of the changes of the landscape.

The impact of landscape elements on biodiversity of small terrestrial mammals
MARŠÁLEK, Martin
The bachelor thesis is dealing with the influence of linear landscape elements on the biodiversity of small terrestrial mammals in an agricultural landscape of South Bohemia. The theoretical part consists of literally review about biodiversity in agroecosystems, ecotones, landscape elements and about ecology of small rodents and insectivores. The aim of the practical part is to compare small mammals' biodiversity in a linear landscape element, on its edge and in surrounding agriculture area. During 2013 vegetation season three three-days long captures were accomplished, CMR method with ears tags was used. In each of three studied biotope a line with 30 traps in 5 metres distances was laid. The species, sex, weight, foot length and age of captured animals were determined. In total, 36 individuals of three species of small terrestrial mammals were captured (Apodemus sylvaticus, Myodes glareolus and Microtus arvalis). The biotopes differ significantly in animal abundance (Chi-Square 66,167; d. f. = 2; p < 0, 0001). The highest species diversity and abundance were found in linear element, where 35 individuals and all the species were captured. In ecotonal zone only one individual was found and there was no individual captured at agricultural meadow.

Ecotons as a dynamic part of floodplain landscape
Halas, Petr ; Lacina, Jan
Varied mosaic of diverse biocoenoses and ecotons rises by natural fluvial processes in alluvium. Dynamic development of vegetation cover was studied in years 1997 – 2007 in flood river bed of Bečva river. Variable mosaic of biocoenoses and ecotons of Bečva river floodplain is considerably varier than regulated and flood undisturbed riverine landscape of Trkmanka river.

Entry to metodology of research of diversity and function of ecotone associations on model forest edges
Halas, Petr
The aim of this article is to summarize some of the new information about function and biodiversity of ecotonal societes, especially societes of forest edges. Use of a few methods for analysing gradients of ecological factors and plant diversity changes is showed on examples of two transects from non-forest to forest vegetation in Stredomoravske Karpaty Hills. The method mentioned above seems to be a good device to understand the function of plant societes on ecological boundaries.
