Fascination by Light
MÁČOVÁ, Nina
The theoretical part includes sections on various theories light and colors concepts in relation to the historical context. It also deals with topics that are directly related to light, such as shading, lighting, etc., and their symptoms in art, painting, glass, mosaic and glass windows. The practical part is trying to capitalize on the knowledge gained in the file author's books as light objects. For those is attention focused mainly on specific features of various materials and their effect on humans in conjunction with the light.

Populační dynamika ruderálních druhů ve vztahu k limitujícím podmínkám prostředí
Modrý, Martin ; Tenčík, Aleš ; Hofmeister, Jeňýk ; Hošek, Jan
Hlavním cílem projektu je identifikace a ocenění významu hlavních podmínek pro rozvoj expanzních druhů rostlin náročných na živiny v lesní vegetaci. Téma je rozděleno do dílčích částí: a) analýza vegetace modelových ploch a její interpretace zaměřená na expanzní druhy, ustupující druhy, indikačně významné druhy, b) stanovení zásoby živých semen v půdě (analýza semenné banky), c) analýza intenzity deště semen, d) stanovení obsahu hlavních živin a organického uhlíku v půdě, event. pomocných půdních charakteristik, e) popis světelných poměrů stanoviště, především kvantifikace celkového světelného požitku a spektrálních poměrů významných pro klíčení semen, f) popis významných spolupůsobících faktorů (vlhkostní poměry, poměry řídící akumulaci opadu, mikro a mezomorfologie stanoviště, spouštěcí faktorys - mechanické disturbance apod.), g) formulace zásad hospodaření podporující zachování biodiverzity na vybraných lokalitách.

Vegetative propagation of selected \kur{Paphiopedilum} species \kur{in vitro}
ROULE, Zdeněk
This thesis represents an initial stage of a study focused on vegetative propagation of \kur{Paphiopedilum} species \kur{in vitro}. The aim of the study is to assess various concetration of TDZ in media and conditions of cultivation for the vegetative propagation of selected \kur{Paphiopedilum} species \kur{in vitro}. This work contains a review of botanical characteristics of the species used, the description of methods, the design, results and discussion of two preliminary experiments.

Anabaena - Phenotypic and genotypic diversity of planktonic strains in fishponds and reservoirs of the Czech Republic
ZAPOMĚLOVÁ, Eliška
Morphological diversity of 61 Anabaena populations of 13 morphospecies was described under the field conditions of Czech fishponds and reservoirs. Polyphasic approach was then applied in classification of 45 clonal strains isolated from those populations. Detailed morphological analyses were performed and partial 16S rRNA gene sequences were obtained for 33 of the strains, and secondary metabolite production was evaluated in 20 strains. Plasticity of morphological characteristics under varied conditions of light, temperature, nitrogen and phosphorus was studied in selected strains, as well as their temperature and light growth requirements. The results were then discussed with respect to the delimitation of single Anabaena morphospecies. A new genus Sphaerospermum was defined for the morphospecies Anabaena kisseleviana, A. reniformis and Aphanizomenon aphanizomenoides, whose phenotypic and genotypic features differed considerably from all other Anabaena morphospecies. Unique information was provided on the occurrence and distribution of A. reniformis and Aph. aphanizomenoides in the Czech Republic.

Avena (Mexico v. United States of America)
Porod, Jakub ; Trávníčková, Zuzana (advisor) ; Zemanová, Štěpánka (referee)
Thesis concerns with the ICJ decision in the case concerning Avena. This decision may serve as an interpretative tool for the institut of consular notification. Consular notification is an international instrument arising from Art. 36 of Vienna Convention on Consular Relations. This thesis analyzes the institut of consular notification in the light of the decision in case concerning Avena as well as another decision. Moreover the decision in the case concerning Avena was the touchstone of the ability of USA to comply with international obligation. Limits and problems of federative system has been revealed during the events following the ICJ decision.

Stomatal development under variable environmental conditions
HOŠTIČKOVÁ, Irena
It is necessary for plants to adapt to variable environment conditions to be able to grow and to propagate themselves. One of the most important environmental factors is water availability. The main role in regulation of transpiration play stomata ? microscopic pores, which control gas exchange (mainly CO2, H2O, O2) between internal and external leaf environment. Number of stomata at the leaf epidermis is influenced by lots of environmental factors, e.g. atmospheric CO2 concentration, irradiance, air humidity, temperature etc. In this thesis I was aiming to study the influence of atmospheric CO2 concentration on stomatal development of Lepidium sativum L. and the influence of irradiance on stomatal development in Hordeum vulgare L.
