V tomto článku je nastíněn základní úvod do problematiky biotransformace a jejich možných negativních důsledků. V textu jsou popsány tři fáze biotransformace a u každé z nich případ, se kterým se čtenář ve svém životě může setkat. Dále je zde jednoduchým způsobem vysvětlena nomenklatura biotransformačních enzymů a transportérů a článek tak celkově poskytuje základní povědomí o komplexnosti biotransformace., This article outlines a basic introduction to the topic of biotransformation and its possible negative consequences. The text describes three phases of biotransformation and each is presented in an example which the reader may encounter in everyday life. Furthermore, in a simple way, the nomenclature of biotransformation enzymes and transporters is explained and thus the paper provides a basic understanding of the complexity of biotransformation., and Ondřej Ženata.
Breeding ecology of woodchat shrikes Lanius senator was investigated in the EL-Kala National Park in North-East Algeria (36°53’N; 8°30’E) in 1998–1999. Quercus suber was the tree species most frequently used as support for nests, which were constructed at a mean height of 5 m. First eggs in clutches were laid 7 May, and clutch size was 4.9. Approximately 42% eggs gave fledglings. Clutch size declined during the course of the breeding season but fledgling success did not. Fledging success was positively correlated with per clutch mean egg length and the height of the nest location above ground. We suggest that the major selective pressures that shape the life history of Algerian woodchat shrikes are relatively heavy predation and poor food availability.
The research activities of this Centre are focused on the study of cyanobacteria, algae and symbiotic soil microorganisms (bacteria and algae), which are used for bioindicatoin and revitalization of toxic anthropogenic substrates and water resources. The targeted outcomes are methods for predicting cyanobacteria in drinking wter and water resources, technology of biogas production from algal biomass and the use of algal biomass for the pharmaceutical industry and biotechnology of microbial inoculations for more effective recultivation of brown-coal spoil banks. The research Centre is divided into three research groups each dealing with a portion of the research task: Group 1 - Cyanobacteria and their toxins in the waterworks industry; Group 2 - Use of algae for bioindication and revitalization of polluted water and biomass use; Group 3 - Use of microbial inoculations for soil revitalization. and Miroslav Vosátka, Jana Albrechtová.
