Change of water habitats characteristics on technicaly unreclaimed spoil banks.
 Ščudlová, Zuzana ; Solský, Milič (advisor) ; Kadlec, Tomáš (referee)
Amphibian decline in recent decades has led to increasing emphasis on monitoring amphibian population abundances. Efforts to assess the condition of each amphibian populations greatly complicate significant natural fluctuations in population size. This may occur particularly in the case of short-term studies that currently prevail. Spoil banks represent a suitable environment for a range of environmental studies. Often these places are not in direct influence of human activities, thus offering the possibility of studying natural processes. On the Hornojiřetínská spoil bank (approximately 6 km2) has been underway since 2005, abundance monitoring of agile frog (Rana dalmatina) and recording and selecting characteristics of water bodies. At the spoil bank is located about 400 aquatic habitats. 225 of them are continuously monitored the development of aquatic habitats and 134 monitored abundance of agile frog. Development of aquatic habitats is not routinely examined unlike development of terrestrial environment. Results showed that the depth of the pond is reduced, surroundings were overgrown and insolation of water level has fallen. Only littoral vegetation showed no change. Abundance of agile frog fluctuated more than 10 times during the studied period, but the data manifested no trends. Decreases slightly outnumbered increases (6 vs. 4), exhibited greater range (1.07 to 6.40 versus 1.69 to 2.40) and and occurred within a longer consecutive period (5 vs. 2 years). Furthermore, it was strong correlation between total abundance and occupied ponds. The results of this study point to the need to establish an appropriate management and the necessity of long-term studies for a correct understanding population dynamics of amphibians.

The use of aquatic biotope for teaching fundamentals of ecology - project
 RÁKOSNÍKOVÁ, Tamara
Bachelors thesis focuses on the use of aquatic habitat for teaching fundamentals of ecology. First, there is an analysis of available textbooks, both in terms of ecological and taxonomical in terms. In the next phase of the work is concerned with the characteristics of selected aquatic habitat, in which the author carried out a survey. The survey focuses primarily on the present taxonomic units. Based on the collected data is elaborated project didactic-methodological procedures used to verify and consolidation-study curriculum. The project activities are designed with the theme of ecology aquatic habitat, often accompanied by worksheets and games with ecological overtones.
