Wood decaying fungi in the natural forest in the southern part of Brdy.
Šourková, Zuzana ; Čížková, Dana (advisor) ; Pešková, Vítězslava (referee)
The aim of my work was to determine the species diversity and frequency of wood decaying fungi in selected areas of natural forest in the southern part of Brd around Třemšín. The site I chose four different areas, where I was looking decaying fungi in the period from April to November.
Further I describe the system of distribution mushrooms, splitting wood destroying fungi, concept tree disease, the importance of fungi in nature, spread of fungi. Described was also monitored site.
Finally, work has formed an overview of wood decaying fungi found on those areas with their frequency of occurrence. Total found 39 kinds of wood decaying fungi from different families. Found wood decaying fungi were photographed and then described.

Problems with pathogenic fungi in the park Stromovka
Kubištová, Pavla ; Čížková, Dana (advisor) ; Šrůtka, Petr (referee)
The thesis describes characteristics of the study area, Královská obora, where the investigation was carried out in the field. It also engages in the description of the studied trees, wood-decaying fungi and damage of trees that occurs and causes problems here, in Stromovka, especially in the most visited areas of the park. Various injuries are a common cause of infection of pathogenic fungi that threatens a stability of trees and hence a safety of the park visitors. Health assessment conducted in location in the park Stromovka, which are problematic due to the occurrence of wood-decaying fungi. The locations were placed at the Planetarium, for the track and along the track. It was focused on the occurrence Meripilus giganteus on beeches, whom they are in the park problems with, particularly on heavily visited sites. 663 trees were inspected in total. The statistical analysis showed that most of the damages of trees in the park Stromovka was dry branches (12 % of the total trees ), probably it was as a result of above-average temperatures in 2015. Only 3 % of the total number of inspected trees were infected by wood decaying fungi. Most of the trees were infected by Inonotus cuticularis (23 % of the total number of found wood-destroying fungi). Meripilus giganteus caused 14 % of the total number of found wood-destroying fungi dameges on the trees in the area. The infestation by pathogenic fungi was not significant on the inspected trees, it could be caused by above average temperatures and below-average rainfall in 2015. At the same time their presence was influent by a felling of trees in studied area from November 2014 to the end of March 2015. It was decided on the basis of dendrological research, that the identified riskiest trees infested by fungi and dying trees with disrupted stabilitye.

The reconstruction design of timber structures of the existing building
Bartlová, Jana ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The content of this work was to carry out construction-technical survey of timber structures of the existing building in order to design an appropriate procedure for their reconstruction. The survey showed construction in an unsatisfactory to disrepair, so further work also includes the static calculation of new structures proposed instead of the current. Timber structure in the building has form of staircase, roof and ceiling construction. Newly designed the following types of stairs and roof trusses from which the lower belts are used as ceiling beams. The new proposal also includes possible roofing, roofing options, developed one of them. The work also includes drawings, bill of materials and cost estimate staircase structure and truss. Specialization in the field of civil engineering is represented by drawings of the new truss and passport (view of current state) whole object on parcel ST.74 / 1, land Tišnov (okr.Brno-venkov), the content of which was the basis for this work.

Zaměření a stavebně-technický průzkum krovové konstrukce kostela Sv. Matouše v obci Postřelmov
Mičunda, Jan
This thesis assesses the state of the truss and steeple of the church of St. Matthew in Postřelmov. The main objectives are to draw the construction, conduct construction-technical survey and and date the construction using dendrochronology. The basic assessment consists in the analysis of the individual parts of the building and their typology. The drawing part of the thesis focuses on the truss, including the steeple. The objectives of the construction-technical evaluation are to assess the structural protection, to locate, identify and detect biological pest infestation; the dendrochronological dating will try to determine the exact year of construction and dates of potential repairs. According to the results, remedial measures will be proposed designed to maintain wood elements in a satisfactory condition.

Defects and pests of wood
REJŽEK, Lukáš
This bachelor thesis describes defects in wood and wood-decaying biological pests. For wood defects are explained causes of formation and their impact on the workability and usability of the material. The chapters on insects and wood-rotting fungi are mentioned the most important kinds of pests, their development in the wood, the level of damage and marginally possibilities of prevention or pest control. The text is accompanied by pictures. A two-part presentation serves for practical use in teaching at primary and secondary schools. The work also includes a collection of defects in wood and wood-boring insect grub holes.

The role of wood decay fungi in the dynamics of a mountain spruce forest
POUSKA, Václav
This thesis is focused on environmental preferences of wood-decaying fungi and their relationships with forest structure and development. Relationships of fungi to properties of wood and forest stands were studied on the basis of field observations in Central-European mountain spruce forests. Plot-based approach was used to reveal a general pattern in the diversity of fungi within a single forest stand and between different stands. The analysis of stand structure provided a background for plot-based approach. Substrate-based approach was used to study single species preferences and their communities. In addition, the influence of wood properties (including fungi and their rots) on the regeneration of spruce on logs was studied.
