Vliv vypalování pastvin na lesní zdroje republiky Zambie
Šanda, Matěj
The aim of this bachelor thesis is to evaluate the loss of forest in Zambia, in a marked locality in the southern province. For the purpose of this research, we used satellite images of the Sentinel 2 satellite, which we subsequently edited in the ArcGis map software so that differences in vegetation and it´s loss can be seen on individual images that are separated by 5 years. Another question is the use of fire as a tool for creating new areas for agricultural and grazing purposes, because Zambia is one of the countries in which fire plays an important role (it deeply affects both the historical and cultural roots of this country). It is very problematic to find a suitable and ecological substitute for burning.
Habitat colonization by neophyte Impatiens glandulifera and estimate of factors limiting its spread
Marková, Zuzana ; Hejda, Martin (advisor) ; Malíková, Lenka (referee)
Invasive spread of neophyte Impatiens glandulifera in central Europe started approximatelly eighty years ago. First records of dense cover stands come from belt stands in riparian habitats. The scale of invaded habitats and degree of the dominance of I. glandulifera is more diversified nowadays. This thesis is objected on the dominance and fertility of I. glandulifera within different habitat types and scale of invaded habitats in different parts of invaded range within Europe (i. e. in Czech Republic and Switzerland). The results show that the height and cover (substitutes for biomass and dominance) of this neophyte (i) correlates with the character of invaded vegetation (ii) relates to the degree of hemeroby (a measure of human impact) negativelly, and (iii), of course, both the growth and dominance are positively affected by nutrient content. Fertility does not differ among the types of invaded habitats, but goes up with the height of I. glandulifera and decreases with its cover. Invaded habitats comprises ruderal and riparian vegetation, but also wet maedows, forest clearances, beach and slope forests or weed vegetation.

Biological characteristics and grow conditions for climbing legumes in permanent grasslands
KRATOCHVÍLOVÁ, Eva
This bachelor´s work is focused on the climbing legumes. Literature review summarizes the importance and ecological requirements of species of meadow vetchling (Lathyrus pratensis) and tufted vetch (Vicia cracca) and describes vegetation types with the occurrence of climbing legumes. Legumes are excellent forage, but they also contain some antinutritional substances and are often attacked by pests and diseases. Production of seed is difficult because of uneven ripening, dehiscent pods, seed dormancy and hard seeds. In the practical part were at selected localities conducted botanical images. These localities were compared with each other in terms of vegetation composition. On the localities were collected pods of monitored species. Seeds were after shelling used to determine seedling and germination.
