The study of the recreational use of El Bierzo (Spain)
Fernandez Arias, Pablo
The main idea of this study is to develop various industries that have this area as well as having a vision of global set both politically Bierzo, economically and socially, in order to implant companies in different sectors later cited with an environmental and landscaping protecion for improvement and enjoyment of all residents and visitors to this area and to protect the different ecosystems, vegetation and wildlife threatened by various industries that can destroy large areas of natural interest. All this is justified by the need to advance a direcion to protect the environment and allow a rural development according to environmental protecion implemented by the various European, Spanish and regional policies for their impact as small as possible. At first discussed in which the climate, geology, hydrology of the area, also the historical-social answer was analyzed and an analysis of the forestry sector, finally has developed an inventory of vegetation and wildlife analyzed It exists in this region. The purpose of this analysis and inventory has been developing and publishing the different conclusions and results that can be read later.

Influence of weather and climate on Ips typographus calamities in Šumava mountains
Tůma, Lukáš ; Sládek, Ivan (advisor) ; Kožnarová, Věra (referee)
European spruce bark beetle (Ips typographus) is a natural forest pest that feeds on coniferous trees, mainly on spruce. Previous studies showed that population growth of bark beetle is supported by warm and dry weather and hindered by cold and humid weather. Temperature affects development rates and influences the number of generations bark beetle may produce during one season; furthermore, it affects survival rates during the winter. Low precipitation leads to water stress of spruce trees which become more prone to bark beetle infestation. High precipitation promotes growth of mold and other natural enemies of bark beetle. The aim of the experimental part of this thesis was to analyze the relationship between population dynamics of bark beetle and weather, using data from the Šumava national park. Data did not show a significant effect of temperature and precipitation on the population growth rate of bark beetle. The growth rate was significantly correlated only with the abundance of bark beetle in the previous year. For further examination of population dynamics of bark beetle in connection with climate characteristics, it would be required to obtain better and more long-term data on bark beetle abundance; harvested bark beetle wood may be influenced by a variety of interfering (e.g....
