Halačka, Karel ; Adámek, Zdeněk ; Jurajda, Pavel ; Mareš, J. ; Kopp, R. ; Grmela, J.
The aim of the methodology is to provide managers and users of small water reservoirs Landštejn type with methodological tools for optimization of the water quality monitoring based on the current level of knowledge and research. Furthermore, provides a design of a methodology for fish community monitoring and optimization of treatments to reduce unwanted fish species and strengthen the status of suitable fish species with the aim of achieving the topdown effect and maintaining or improving water quality in these water reservoirs. The presented methodology summarizes the findings obtained during the monitoring and evaluation of selected parameters of water quality, planktonic and fish communities in water supply reservoirs Landštejn in recent years. It also contains an evaluation of applied treatments, focused mainly on fish stock. Unwanted fish species were caught and the predatory fish were stocked with the aim of optimizing the fish community composition and positively influencing the quality of the water in the reservoirs. The methodology contains recommendations for monitoring of the water quality in the reservoir, including monitoring of planktonic communities, monitoring of fish and recommended manipulation with fish stock. The methodology provides guidance and information for optimization of monitoring and treatments for small water supply reservoirs of the Landštejn type.

Methods of detection of fungal diseases applicable in plant phenotyping and remote sensing
Klem, Karel ; Veselá, Barbora ; Holub, Petr ; Urban, Otmar ; Mezera, J.
This methodology summarises findings from a comparison of three perspective methods of fungal disease detection applicable for remote sensing and plant phenotyping of fungal disease resistance. These methods are spectral reflectance, infrared thermal imaging, and blue-green fluorescence imaging. On the example of winter wheat infection with powdery mildew, stripe rust and brown rust the strengths and weaknesses of individual methods were demonstrated. From these results it is evident that all three methods are potentially applicable for non-destructive fungal disease detection, but their practical use may vary. Testing of spectral reflectance indices for the detection of fungal diseases showed particularly the high detection reliability of the red-edge and green band based spectral vegetation indices. Infrared thermal imaging has shown high detection accuracy for powdery mildew and brown rust, but lower for stripe rust. Blue-green fluorescence and thermal imaging seems to be also a very promising tools for evaluating the intensity and spatial distribution of infection on a leaf level.

Integrated weed management in cereals
Smutný, V. ; Winkler, J. ; Klem, Karel
Certified methodology summarized knowledge about the impact of different non-direct (preventive) agronomic measures (crop rotations, soil tillage, fertilization using organic fertilizers and straw management) on weeds (weed seedbank and actual weed infestation), from qualitative (weed specie composition) and quantitative (intensity occurrence) point of view). There is also particular focus on rationalization of chemical methods of weed management (herbicide application). Principles of decision-making rules based on establishment of economic thresholds, optimal timing of application and optimization of herbicide doses. There is a potential for decrease of applied herbicides in cereals using of this approach, which brings not only considerable economic savings, but also reduction of negative environmental effect caused by herbicide use.\n\n

Methodology for ecosystem accounting at the national level
Vačkářů, Dava ; Grammatikopoulou, Ioanna ; Harmáčková, Veronika Zuzana
The aim of this document is to provide methodological framework for ecosystem accounting at the national level. Ecosystem accounting is a coherent and integrated approach to the assessment of the environment through the measurement of ecosystems, and measurement of the flows of services from ecosystems into economic and other human activity. Therefore, ecosystem accounting enables to account for the supply and use of ecosystem services within the system of national environmental statistical accounts.This methodology provides framework for the measurement of ecosystem services flows from the environment to the economy, supply of ecosystem services by ecosystem units, use of ecosystem services by economic sectors, and accounting for monetary value of ecosystem service flows and assets. The methodology presents examples of ecosystem accounts and describes their structure. The methodology should support development and implementation of ecosystem accounts within satellite environmental accounts of System of Environmental and Economic Accounting (SEEA) and serve as a reference for methodological developments in experimental ecosystem accounting

The methodology for bit-level preservation of digital data
Růžička, M. ; Miranda, Andrea ; Hejtmánek, L. ; Vašek, Zdeněk ; Krejčíř, V. ; Bartošek, M.
The aim of the digital data bit-level protection methodology is to provide recommendations for implementing Long Term Preservation (LTP) storage. The methodology provides guidance on how to address the problem of bit protection of digital data in the environment of Czech libraries on the basis of good practice in this area available in the Czech Republic and worldwide. At the same time, this methodology is connected to project ARCLib , which aim is to develop open source LTP system. For wide availability to the libraries of the Czech Republic and elsewhere, the whole recommendation is based on freely available technologies with open source text and licenses allowing further development and adaptation to the needs of the user.

Preparation and storage of fish samples for flow cytometry
Halačka, Karel ; Vetešník, Lukáš ; Mareš, J.
Flow cytometry enabling rapid measurement of cellular DNA content has been widely used in ichthyology and fishery practice. The aim of the methodology is to contribute to optimization of work on the flow cytometer by helping with the selection, sampling and possibilities of fixation of analyzed tissue and interpretation of obtained data. The target group are people from fishery companies and ichthyologists dealing with the problem of the fish population structure in free water. During the sampling and analyzing of samples problem can be limited availability of fixative and techniques as well as analyzes of material not originally retained for the purpose of ploidy determination. Typical examples are temporary usable or archive preparations, museum material, etc. For the verification were preferred representatives of polyploid complexes or economically exploited species with a known existence of polyploid individuals.
