Jiřička obecná (Delichon urbica) v kulturní krajině České republiky
Dvořáková, Denisa
In the literature review, the work focuses on gathering information about this species, including its protection, mainly in the Czech Republic, but also in the world. The practical part deals with Martins habitats, examines the expansion and breeding density in the town Lomnice, in 2016. Information about nesting in the locality was acquired by exploring areas, all nests were counted and information about the previous nesting was gathered from the remains of the former nests. Furthermore, the work deals with monitoring of the general public awareness of the species Martin and how they would act, if, for example, Martin built a nest on their house. This information was obtained from survey, but also from literary sources. The work concludes that Martins are now more or less human-dependent and the size of its population has not changed much. To keep this state as it is, or to improve it in the future, it is necessary to monitor the development of breeding abundance and when it observed decline, provide corrective measures (artificial nest, correct type of plaster in buildings).

Hnízdní preference jiřičky obecné (Delichon urbica) v urbánní krajině
Dvořáková, Denisa
The thesis evaluates the birdlife preferences of the common house martin in the territory of the Czech Republic. The survey of the literature focuses on obtaining information from available sources that relate to nesting preferences according to different criteria, such as environmental habitat conditions, influence of the human factor, and others. In the practical part of the thesis 12094 records have been collected concerning the nesting of the common house martin in the Czech Republic in the period from 2009 to 2017, drawn from the faunistic database of the Czech Society for Ornithology. The data was correlated with the data on the conditions found in the separate habitats and analysed by the statistical methods Boosted regression trees (BRT) and Generalized Least Squares (GLS). The obtained results show that owing to the insect life the common house martin most prefers the areas with field and wetland ecosystems, and rather also the suburban lowland region. A major negative influence on the common house martin appeared to be mining areas in industrial estate.
