Environmental Management Accounting (EMA) is a system, which collects, records, evaluates and disseminates information about environmentally induced financial impacts and environmental impacts of the system itself. EMA is an important source of information for decision-making processes such as management of an organization, for EMS or environmental reporting. Identified barriers were included in the study which was conducted in three phases - in organizations espousing to Responsible Care, in selected companies with ISO 14000 and in companies with environmental management systems, validated by European EMAS. In early 2010 research was completed in the field of environmental management accounting and barriers defending the implemention of EMA to organization's information system and the subsequent use of EMA. Primary data obtained from this study were subjected to cluster analysis and the results are presented in this scientific thesis. In practise there are many obstacles to full-fledged EMA implementation process into practice organization and its functioning. Findings of the study give answers to the question: "What barriers act as obstacles to the implementation of EMA into the practise of the organization and its functioning?"

One of the essential genetically subjected behaviours of a bee-colony is swarming. However, in the time of queen breeding and technical approach to colony division, swarming constitutes a problem in the effectiveness of controlled beekeeping and subsequently in decreasing of the attainable economic profits. The intensity of swarming is a polyfactorial phenomenon whose characteristic feature is seasonality (the availability of breed, course of weather) so the swarming intensity is different in particular years. This study is connected with the research carried out at the Department of Zoology, Fisheries, Hydrobiology and Apiculture at Mendel University in Brno.
The experiment focused on the relationship between the swarming and biological state of bee-colony was realized in three seasons of the period 2003-2005. Experimental bee-colonies were stimulated to the swarming fever by zoo-technical practices, at the same time the biological status of given bee-colony was observed. Within the process of marking of newly emerged workers there was observed their number continuously during the particular season. The samples of 3- and 4-week-old workers were instrumental to the analysis of the development of their hypopharyngeal glands. The study has proved that a) bee-colonies building higher number of queen cells are likely expected to be in swarming fever, b) 3-week-old workers have hypopharyngeal glands in higher stage of development than 4-week-old workers, c) higher stage of swarming fever is closely correlated with higher stage of development of hypopharyngeal glands. These facts can contribute to the comprehension of the reason and relationships of the swarming.

In the year 2001, the European Comission started to revise the legislation Solvency I and to implement a new approach called Solvency II. The regulation called Solvency II is based on regulation considering management of risks of commercial insurance companies. Changes on financial markets and the contemporary financial crisis made financial authorities to formulate principles of regulation based on risk management. Commercial insurance companies across Europe will face a considerable amount of work to be ready for requirements related with Solvency II implementation in the year 2012.
Rating agencies, regulators and investors today are demanding that insurers provide detailed assessments of their risk tolerance and quantify the adequacy of their economic capital. To complete such assessments requires a credible baseline for underwriting volatility. Modern portfolio theory for assets teaches that increasing the number of stocks in a portfolio will diversify and reduce the portfolio risk, but will not eliminate risk completely, the systemic market risk remains. In the same way, insurers can reduce underwriting volatility by increasing account volume, but they cannot reduce their volatility to zero. A certain level of systemic insurance risk will always remain, due to factors such as for example the underwriting cycle, macroeconomic factors, legal changes and weather.
This presented scientific paper focuses on an analysis of specific goals of the regulation Solvency II and the structure of second pillar of the three-pillar construction (similarity with Basel II banking regulation) of Solvency II. The paper was written as part of research project MSM 6215648904, carried out by the Faculty of Business and Economics, under the title "The Czech Republic in the processes of integration and globalization, and the development of the agriculture and service sector in the new conditions of the integrated European market", following the goals and methodology of the research project.

The aim of the research work was to evaluate phytotoxicity of mesotrione in poppy (Papaver somniferum). The amount of spraying water (150, 300 and 450 l per hectare) was compared as well. In the end, the different growth stimulators (Atonik - 0.6 l.ha^-1, Route - 0.8 l.ha^-1) and the adjuvants (Atplus 463 - 0.5% solution, Silwet 77 - 0.1 l.ha^-1) wre tested. Degree of phytotoxicity of individual variants was assessed by measuring chlorophyll fluorescence (parameter: maximum quantum yield of electron transport in photosystem II - QY) in 1st to 21st day after treatment. The results showed that the application of mesotrione caused phytotoxicity on poppy plants. The most significant phytotoxicity is evident at doses of 450 l spraying water per hectare. Addition of growth stimulators and adjuvants increases the phytotoxicity (decreases the value of QY) compared to the herbicide application itself. The mesotrione reduced the weight of dry plants by 15 % (150 l of spraying water), 1 % (300 l of spraying water) and 64 % (450 l of spraying water) compared to control variant.

Competitiveness of national economies depends in great part on technological development and implementation of knowledge from science and research in practice. The phenomenon of cooperation represents an integral part of these processes. While its bounded forms, like mergers and acquisitions are relatively embedded in the Czech Republic, the advantages of less formal partnerships have been gradually discovered just recently.
In the paper we focus on a special type of cooperation called networks. In order to get an initial overview, we introduce some of the basic definitions, as the specialized literature lacks single explanation and categorization. Within the framework of our research we have focused on such purposeful connections of small and medium enterprises that bring benefits for both sides and lead to the growth of competitiveness. The aim of the article is to investigate the prerequisites of interfirm network operation in the South Moravian Region.
The first part of the paper introduces network cooperation, especially the motives standing behind network set-up, the typology of networks and the role of networks at regional level. Then we briefly describe the South Moravian region, where our investigation has been made. We focus especially on the demonstration of the most powerful and perspective economic branches in which we consider networks very important. This base is further extended by the information received in the South Moravian Innovation Centre, an interest association of legal persons having experience especially in research institution - company cooperation. The operation of a partnership network is analyzed on the case of DC Concept, a. s., a company from Brno producing and developing information system for middle and large companies. We introduce the six types of their partners, the system how the network works and the motives lying behind.
The paper is based on the information gained during the pre-research which falls within the scope of doctoral dissertation research focusing on network creation of small and medium enterprises in a certain region.

The pepper (Capsicum annuum L.) is very popular annual vegetable either for fresh consume either as spice after drying and grinding. The fruit contains high amounts of vitamin C, provitamin A, E, P (citrin), B₁ (thiamine), B₂ (riboflavin) and B₃ (niacin). Crop Research Institute (CRI), Department of Vegetable and Special Crops, Olomouc, the Czech Republic is the holder of the collection of pepper genetic resources. The collection of pepper consists of 504 accessions, currently. It is necessary to find duplications within collection for effective work with genetics resources. For analyses totally 41 accessions were chosen. These were divided into ten groups according name: 1. Astrachanskij, 2. Aufrechte Cayenne, 3. Bogyisloi, 4. Hatvani, 5. Japan Hontakka, 6. Japan Madarszen, 7. Kalocsai Fuszer (Edes), 8. Konservnyj Belyj 289, 9. Tetenyi and 10. Vinedale. Two approaches were used for the detection of duplications - morphological description and polymorphism of DNA. The accessions were characterized for 54 morphological traits: 1 character in seedlings, 8 characters in the plants, 10 characters in leaves, 10 characters in flowers and 25 characters in fruits. The polymorphism of DNA was analysed using the SSR (Simple Sequence Repeats) method with 8 SSR markers (Hpms 1-1, Hpms 1-5, Hpms 1-168, Hpms 1-172, Hpms 1-274, Hpms 2-21, Cams 163 and Cams 647) which are localised on different chromosomes. The results from DNA analysis were complemented with the morphological characterization. Possible duplications were in 4 groups: 1. Astrachanskij, 4. Hatvani, 5. Japan Hontakka and 7. Kalocsai Fuszer (Edes). This work is the first step for the determination of duplications in the Czech germplasm collection of pepper.

Zoobenthos of the Fryšávka Rivulet was investigated in the years 2007-2008. Research included also physico-chemical factors of water (temperature, pH, conductivity, oxygen saturation). Altogether, 144 taxa of zoobenthos were determined in the Fryšávka Rivulet: Coelenterata (1 taxon), Turbellaria (1 taxon), Oligochaeta (6 taxa), Hirudinea (1 taxon), Mollusca (5 taxa), Amphipoda (1 taxon), Decapoda (1 taxon), Acari (1 taxon), Ephemeroptera (18 taxa), Plecoptera (18 taxa), Heteroptera (1 taxon), Megaloptera (1 taxon), Planipennia (1 taxon), Trichoptera (36 taxa), Coleoptera (8 taxa), Diptera (44 taxa). Altogether, 76 taxa of zoobenthos were determined in Medlovka brook: Coelenterata (1 taxon), Turbellaria (1 taxon), Oligochaeta (2 taxa), Mollusca (1 taxon), Isopoda (1 taxon), Amphipoda (1 taxon), Acari (1 taxon), Ephemeroptera (14 taxa), Plecoptera (8 taxa), Megaloptera (1 taxon), Trichoptera (17 taxa), Coleoptera (6 taxa), Diptera (22 taxa).
The average abundance of zoobenthos of the Fryšávka Rivulet was 3208 ind.m^-2, the average biomass was 7.5 g.m^-2, respectively. The same values for the Medlovka brook were: abundance 3238 ind.m^-2 and biomass 5.8 g.m^-2. The average value of the saprobic index for the whole Fryšávka Rivulet was 1.25 (oligosaprobity), for the Medlovka brook 1.42 (oligosaprobity).

The present work gives the results of the research of macrozoobenthos some running waters drainage areas of the Dyje River (southern Moravia - Czech Republic). Altogether, 762 taxa of macrozoobenthos were determined from the running waters of southern Moravia. Porifera (3), Hydrozoa (3), Turbellaria (8), Nematoda (14), Nematomorpha (1), Oligochaeta (60), Hirudinea (18), Bryozoa (5), Mollusca (44), Isopoda (2), Amphipoda (4), Decapoda (2), Hydracarina (17), Ephemeroptera (65), Plecoptera (55), Odonata (26), Heteroptera (3), Plannipennia (2), Trichoptera (128), Coleoptera (59), Diptera (243). Some taxa of macrozoobenthos are extinct unfortunately in running waters of Southern Moravia at present time. Another ones appear newly, for example snail Potamopyrgus antipodarum from New Zealand or Dreissena polymorpha from Pontic region. The data presented in this paper may serve as a basis for future monitoring of water quality and zoobenthos composition in connection with presumption of climate changes.
