Dendrochronology of representative autochtonnous tree species on environmental and temporal gradients
ČEJKOVÁ, Alžběta
This thesis is focused on application methods of dendrochronology on various ecological and historical aspects of forest communities, human management practices, and historical utilization of wood. Studies revealed growth responses of trees in various type of forest vegetation represented by spruce forest, alder carr and alluvial forests and involved autochthonous tree species with all morphological types of wood. These works demonstrated necessity of dynamic evolving of the regional chronologies for the Czech Republic.
Detection of frequency along an altitude gradient and its influence on tree vegetation in natural forests of NP Seoraksan (South Korea) based on using tree rings data.
PLENER, Tomáš
The thesis presents a grant application for a project dealing with research on disturbance frequency and influence on a structure and composition of tree vegetation in mixed oak forests in National park Seoraksan (South Korea). The aim is to verify and deepen current knowledge of disturbance and suggest adequate protection management based on the information obtained.
The beginning of the castle Český Krumlov - the castle as a symbol of power and aspect of cultural transfer
GERSDORFOVÁ, Zlata
This work deals with beginning of the castle Český Krumlov. It takes South Bohemia area as the area of cultural influences, which overlaped itself (Bavaria, Bohemia, Austria) and simultaneously as a scene of colonizational proceses. They were discharged namely by Vítek's genus. In this place, we have to remember a network of Vítek's family bindings which had an influence to cultural transfer, which bounced at level of power means ? we can talk about constitution and presentation of Vítek's genus and his clannish background, it means a genesis of settlemental town and castle. The castle was taken as a symbol of power, but also as an intersection of potential interdisciplinary approach, which uses limited possibilities of historical and archeological research and simultaneously uses new interpretative and datative possibilities. The aim of this work is an attempt to classify the castle Český Krumlov to the absolute chronology and to bring a contribution to discussion about its ancient history.
Vegetation analysis and growth characteristics of \kur{Dryas octopetala} on transect in Arctic tundra of Svalbard
BARTOŠOVÁ, Alena
In this work I try to describe vegetation variability on altitudinal gradient in High Arctic tundra of Svalbard and dendrochronological characteristics of dwarf-shrub Dryas octopetala. Field experiments have been made near Petuniabukta (central part of Spitsbergen, Svalbard).
Dendrochronological dating of building elements of mill in Slup
Kloiber, Michal ; Kolář, T. ; Merta, O. ; Rybníček, M.
This work is completed by technical diagnostic of wood constructions. Technical diagnostic made an inquiry actual condition of these wood constructions by visual and equipment methods.
Dendrochronological dating and diagnostics of historical wooden structures
Rybníček, M. ; Kloiber, Michal ; Kotlínová, M. ; Wondráček, L.
We may classify preserved historical wooden structures as important documents of how advanced the material culture of our ancestors was. An important task for our society is to spread knowledge which helps preserve the maximum number of authentic wooden structures. The objective of the contribution is to get informed about methodological procedures which are used in the construction/historical and construction/technical research of historical wooden building structures.
Timber Roofs in the Southern Part of Bohemian-Moravian Uplands
Bláha, Jiří ; Kyncl, T.
The vast majority of historic roofs in the region belong to the common rafter and collar typological group. The large diversity and variability of technical solutions, especially noticeable in the lengthwise frame construction allows us to trace the evolution of traditional carpentry as well as to map its local differences. The Bohemian-Moravian Uplands region is one of the relatively homogenous areas, where the timber transport distance from the place of felling the trees to the site was very short. There are no large rivers, and the altitude is 500-840 meters (about 1500-2500 ft.)above sea level.
Using of the tree-ring analysis for dating of large scale dieback of dwarf pine (Pinus mugo) in the Giant Mountains
Kyncl, Tomáš ; Wild, Jan
Abrupt growth depressions and high proportion of missing tree-rings was observed on dwarf pine shrub (Pinus mugo) in Krkonoše, Mts. These symptoms were ascribed to strong defoliation of shrub caused by insect outbreaks and confirmed by observed decrease in shrub cover using historical aerial photographs. The study proved the using of dendrochronological methods for detection of historical inasect outbreaks in dwarf pine shrub stands.
Non-destructive Survey of the Late Gothic Wooden Door Frame at the Pernstejn Castle
Bláha, Jiří ; Kyncl, T. ; Anthony, R.
Photographic, x-ray and drawn documentation of the oak wood door frame dendrochronologicaly dated by means of non-destructive tree ring measuring to the years 1480-97
To possibility of dendrochronological dating in north Middle Danube area
Dvorská, Jitka ; Poláček, Lumír
In the region of middle-east Europe at the end of 90th years of the 20th century arouse a number of the new dendrochronological laboratories, which significantly help to a dating of archaeological sites from the early middle age to the modern period.
