Function of honey-bee (Apis mellifera) in see industry of field crops.
PŠENIČKOVÁ, Zuzana
In this dissertation I am trying to point out the importance of the honeybee in the pollination of plants and the connection between the plant and the honeybee. The honeybee is essential and indispensable part of agricultural production that increase in the hectare production. It is also importat in forests, fields and in orchards. In the introduction there is a telling about bee colony and alternative ways of pollinate. In this dissertation I outline economic and ecological features of beekeeping and problems that beekeepers have to solve, some grants from the European Union that help to our beekeepers. In conclusion there are described some problems and different opinions for geneticaly modified plants and their influence for the honeybee.

Thoughts of Plants
ŠOBROVÁ, Lenka
This diploma thesis called "Thoughts of Plants" consists of two parts, theoretical and practical. The theoretical part focuses on an explanation of the basic thoughts and inspiration that comprise the main resources for the practical part in my thesis. In context of this thesis subject, there is a documentation of the main points in the current art scene, which deals with plant and landscape detail. The practical part is composed of the monumental triptych connected to the subject. This triptych is made of acrylic paint on canvas.

Vegetation of heat pipelines and participation of invasive species
SVĚTLÍKOVÁ, Petra
Both climate change and plant invasions are phenomenons affecting vegetation structure and its functioning. This study compares vegetation of heat pipelines with surrounding vegetation and investigated survival of thermophilic species in the zone on heat pipelines. Reactions of plants on global warming, including possible invasive behaviour of alien species, are briefly discussed.

Rural villages as biocentres. Plants mapping utilization for biodiversity evaluation.
JURÁŠ, Jan
Rural villages are important elements in cultural landscape. Thanks his variety here often enact biocentres and make possible to existence wide spectrum of plant, that could occur in other places and by other conditions only rock hard. At present however happens under the thumb of wasteful management to typical provincial nature suppression and to extinction of some species. This work was bent on vegetation investigation in three villages in Volyňsko in district Strakonice. Ascertained kinds spectrum distinguish on the basis of many factors, for example location position, abiotic factors or way of management. To other subject of interest was derived, let us say invasive kinds occurrence as well as protected species. On the basis these results can tell, that the rural villages are in monotonous agricultural landscape significant biotope that it is necessary to protect.

Phytoremediation of air - plans and reality
Vaněk, Tomáš ; Maršík, Petr ; Soudek, Petr
Results obtained so far indicate that selected plants can be effectively used to remove contaminants from the air, both horizontally and especially near sources of contamination, such as roads. When choosing plants, it is necessary to pay attention to their sorption capacities, as well as their ability to survive in contaminated sites, which are also exposed to other stresses such as lack of moisture and salinity.
