Leaf area index development and radiation use efficiency of a poplar short rotation coppice culture
Tripathi, Abishek ; Fischer, Milan ; Trnka, Miroslav ; Orság, Matěj ; Vanbeveren, S. ; Marek, Michal V.
Leaf area index (LAI) is the most appropriate parameter for analyzing canopy structure and crop productivity. LAI and radiation use efficiency (RUE) were estimated to evaluate the productivity of a short rotation coppice culture of a poplar clone. RUE was calculated as the ratio between total aboveground woody biomass and available photosynthetic active radiation (PAR) accumulated during one growing season. Prior to coppicing, LAI reached a maximum value of 7.3 (in 2009), whereas the maximum LAI after coppicing was 6.8 (in 2012). The maximum RUE reached prior to coppicing was 0.25 g mol−1 (in 2009), while after coppicing it was 0.20 g mol−1 (in 2012), which did not represent a significant difference (p > 0.05).

Financial analysis of PETROF, spol. s r.o.
Marek, Michal ; Čámská, Dagmar (advisor) ; Krause, Josef (referee)
The goal of this bachelor's thesis is to analyse financial health and stability of PETROF, spol. s r.o., by using methods of financial analysis. This company is well known manufacturer of pianos not only in the Czech Republic, but all across the Europe. As a data source were used data officially published by the company from years 2009 to 2013. The tools chosen for this bachelor's thesis are explained in the theoretical part, then, in the practical part, they are applied to analysed company with enclosed commentaries and some of them are measured against competitors.

Nature protection analysis in the Czech Republic by GIS
MAREK, Michal
This thesis deals with geographical information systems, that are trying to in-depthly talk over and explain all of the requirements. It focuses on data models, particular programs or on required hardware that is needed to make it happen. Further is it dealing with landscape protection. It deeply looks for example at landscape character, czech legislation of landscape protection and few chosen projects such as cenia or inspire outside of regular description. And it finally decsribes web mapping applications in Czech republic. Examples of them are possibly MapoMat, server of KRNAP and Klíšťata.

Short rotation coppice poplar hybrid clone J-105 (Populus nigra x P. maximowiczii) is studied as an alternative source of bio-energy in the region of Czech-Moravian Highland. The plantation was established in 2001 at the locality Domanínek in the vicinity of Bystřice nad Pernštejnem (Czech Republic, 49o32’N, 16o15’E and altitude 530 m a. s. l.) where mean annual rainfall of 609 mm and mean annual temperature of 7.2oC was recorded between 1981 and 2010. The total area planted with the clone was close to 1.5 ha with total plantation area being close to 3.5 ha. The plantation with planned density of 9,216 trees ha-1was established on the former agricultural land and the length of the rotation cycle was set to 6-8 years. At the beginning of the second rotation period i.e. in spring 2009 (following winter harvest), the plantation was divided into four randomized blocks with different nutrient treatments and three replicates (4×3). These treatments comprised of application of mineral NPK fertilizer (nitrogen 305 kg ha-1, phosphorous 154 kg ha-1 and potassium 291 kg ha-1), sewage sludge (4200 kg/ha-1) and ash (1000kg ha-1) and lime (5 ton ha-1), while control was with natural nutrients content only (deposition and leaves mineralization). The objectives of the study were to estimate the above ground annual yields (based on allometry and stem inventory), the mortality and the shoot to stump ratio as the main productivity characteristics.

Global climate change and regional impacts on forests in Beskydy Mts
Janouš, Dalibor ; Cudlín, Pavel ; Čermák, P. ; Marek, Michal V.
Beskydy Mts. is a region with a relatively high probability of expansion of serious Norway spruce stand fade-away types which are accompanied with gradations of insect pests and fungi pathogens as mortal factors. The study is focused on individual factors of change of forest trees growth conditions: increased CO2 concentration, drought, temperature, extreme weather, dimming effect, nitrogen deposition. Furthermore, it recapitulates briefly current state of forest stands in Beskydy Mts. and it defines procedure of estimation of spruce stand degradation risks.
