Public use of forest, landscape and public greenery
Paštová, Ladislava ; Svoboda, Petr (advisor) ; Vedral, Josef (referee)
The diploma thesis is focused on Czech legislative of public use of forest, landscape and public greenery. Everyone has right to enter the forest and to pass the landscape and public greenery except estates that are excluded from public use. The public use is legal limit of property law. The owner's of estates duty is to tolerate public use, i. e. to allow enter his estates. The owner of forest can allow some activities in forest which are prohibited by law. Forest enclosures are examples of specific use of forest. The entrance in forest enclosure can be restricted. Different legal regime is in protected areas. The entrance in given area can be restricted to tourist trails or completely excluded due to nature conservation. Some activities are allowed only with permission of nature conservation body or based on general measure. The Czech legislative does not have the legal tool in cases of owner hampers users in use of studied subjects of public use.
The role of hybridization in plant evolution - using different methods for detecting plants of hybrid origin in the Elytrigia repens - Elytrigia intermedia hybrid complex

Hybridization is an important phenomenon in plant evolution because it is one of the sources of new genetic variability. Hybridization is the merging of genomes of formerly isolated evolutionary lineages. In many taxonomic groups, the detection of plants of hybrid origin is challenging. A wide spectrum of methods for their detection has been employed since the beginning of botanical research. The introduction of genomic in situ hybridization has had a great impact on the study plants of hybrid origin. This molecular cytogenetic approach allows to reveal the genomic contributions of particular parental species to hybrid taxa. The tribe Triticeae is a prime example of a group whose present-day diversity has been strongly influenced by hybridization (together with polyploidy). The majority of its species are allopolyploids resulting from frequent interspecific and intergeneric hybridization. The structure of relationships within the tribe is therefore highly reticulate. This thesis includes three papers dealing with the hybrid complex of Elytrigia repens - E. ×mucronata - E. intermedia: (1) The representatives of this hybrid complex are morphologically poorly differentiated, and only two morphological characters are used to their distinguishing. Among anatomical characters on the leaf blade, some...
