Changes in the distribution of invasive neophytes in the riparan vegetation of the Berounka river
Randová, Nela ; Matějček, Tomáš (advisor) ; Lipský, Zdeněk (referee)
Riparian vegetation along the water courses is one of the places that are highly vulnerable to the spread of invasive alien plants. Water corridors allow their easy and rapid spread to new area. The diploma thesis occupies with changes in the distribution of the invasive neophytes in the riparian vegetation of the Berounka river during the years 2015-2018. The objective of this study was to find out how changes in the course of each year will be reflected and whether a certain trend of population development can be traced. In connection with this, the thesis occupies with the possible influence of extremely dry years 2015 and 2018 on the occurrence of invasive neophytes. Field research took place on the banks of the Berounka river from the village of Čilá near Skryje to the confluence of the Berounka and Vltava river in Prague-Lahovice during the summer months in 2015, 2016, 2017 and 2018. The riparian vegetation was divided into 500 ± 150 m long segments. There were 90 segments where the occurrence and abundance of 17 invasive neophytes were mapped. In total, occurrence of 14 taxons was registered. The most frequent taxons were Robinia pseudacacia, Impatiens glandulifera and Solidago sp. in the Berounka riverbank vegetation. The highest number of specimen was recorded for invasive neophyte...
Habitat preferences of red deer in the Giant Mountains NP
Hazdrová, Kristýna ; Romportl, Dušan (advisor) ; Lipský, Zdeněk (referee)
The thesis deals with the evaluation of habitat preferences of the red deer in the Krkonoše National Park. In the context of Central Europe, the Krkonoše Mountains are an important locality in which many rare and protected ecosystems are located. The current management is trying to restore the species composition of the forest, which was abundant in the past and replaced by atypical spruce species. Red deer (Cervus elaphus), which lives in these forests, has no natural enemy in the Giant Mountains, so it is necessary to control the local population and perform selective management for the purpose of forest protection. For proper management planning it is important to know the life strategies of the red deer: the deer's preffered habitat, physical-geographical characteristics that affect its movement and spatio- temporal use of the area. This information can be obtained through GPS-telemetry collar monitoring. The monitoring campaign in the Giant Mountains was carried out between 2014 and 2018 and the resulting data are used in this work. Information on 71 individuals of red deer are processed and subjected to spatio-temporal analysis, which shows that deer behavior is influenced by both daily and annual cycles. Another aspect influencing its movement is the density and intensity of the use of...
Territorial system of ecological stability (ecological networks), the evidence and an analysis of newly established biocenters and biocorridors in model area
Hofman, Milan ; Lipský, Zdeněk (advisor) ; Skaloš, Jan (referee)
The ecological networks are a widely discussed subject in a local and a pan-European scale. There were a formation of the Territorial system of ecological stability in Czechoslovakia during eighties. TSES can be considered for a main part of ecological networks. Understanding the theoretical basics and a delimitation of ecological networks and TSES are necessary. These knowledges allow a correct application to practice. Therefore a main part of the study is literature search. There are summarize important studies of this interdisciplinary subject in the bachelor thesis. New elements of TSES have been creating almost thirty years. Their registr and evaluation should be an integral part of the process. We have found out sixteen new elements of TSES in the Kutná Hora district. We researched seven of them. We focused on a contemporary composition of trees and bushes. We analyzed it with project documentations and we tried to predict a future prosperity. New elements of TSES still need to care that depends on specific conditions of each habitat.
History and present state of the landscape of the former fish pond system in the drainage basin of the Opatovický kanál channel (Central and Eastern Bohemia)
Leglerová, Anna ; Lipský, Zdeněk (advisor) ; Pavelková, Renata (referee)
This work is focused on the dynamics of landscape change of fish pond system in Polabí region, specifically the drainage basin of the channel Opatovický kanál. Theoretical part provides information about origin, development and present state of fish pond system. Experimental part provides the mapping of ponds in five time periods covering the epoch between the 18th and the 21st century. Information about ponds in the 16th and the 17th century are provided as well but without pond areas. The reason for their absence is insufficiency of sources. Development of the area and quantity of ponds is discussed as well as land use and land cover change on the extinct pond areas. Finally, application of the fish pond development knowledge in landscape planning and revitalization are discussed based on the information gained by the mapping and research. Key words: fish pond systems, land cover, land use, landscape changes, Polabí region, drainage basin of the channel Opatovický kanál
