Periodic Water Bodies and Their Biota.
Bušová, Tereza ; Říhová, Dagmar (advisor) ; Škodová, Jana (referee)
This thesis is focused on a description of small periodic water bodies and their biota. These telms are formed as a result of heavy spring rains, floods, melting snow or the ground water level rising. They are formed on green parts, non-green parts or fallen parts of a plant (in that case they are called phytotelmes), in water-filled tree-holes (dendrotelmes), in fissures of rocks (lithotelms) or in various cavities, artificially created by human - in empty jars, water- filled tires, flower-holding vases in cemeteries etc. The thesis deals mainly with dendrotelmes and phytotelmes which are the most frequent, especially in tropics. It provides the information about their formation and animals that lives in these small habitats. Also, a taxonomical review of the main reported fauna was added for better orientation of the reader. The most common taxa which occur in temporary pools are families of mosquitoes (Culicidae), chironomids (Chironomidae) and ceratopogonids (Ceratopogonidae). There are also present other Dipteran larvae or larvae of scirtid beetles from the family Helodidae. Some of the animals living in the pools used different evolution strategies to be well adapted to deal with periodicity and drying out of the water bodies. Their overview is also included in this thesis. Furthermore,...
Sezónní dynamika obsahu manganu v bylinném patru, půdní a epigeické fauně
Bradáčová, Eliška
The aim of this thesis is to determine the level of manganese content and its seasonal dynamics in selected herbs and trees species and invertebrates in the period 2011--2013. Trial sites were located in the highly manganese contaminated ecosystem in Krušné hory mountains. The flora and fauna samples were being collected on a monthly basis. The level of manganese was determined by the AAS method. The highest level of manganese was found in the blackberry bush (Rubus caesius L.) and the raspberry bush (Rubus idaeus L.). The larch (Larix decidua Mill.) and the mountain ash (Sorbus aucuparia L.) were the most contaminated tree species. Majority of plants accumulates manganese during the vegetative period. The invertebrates showed lower level of manganese content than plants. The highest level was found in millipedes (Diplopoda) and isopods (Oniscoidea). Despite the really high concentration of manganese in the enviroment, none of the plants and invertebrates showed symptoms of toxicosis.
Invertebrates in Human Habitats as a matter in Extracurriular Education
ČAPKOVÁ, Zuzana
The Bachelor thesis deals with synanthropic invertebrates. Through the research itself, their presence in selected households was being investigated. The results were compared with literature data. Based on both literature and research data, a project for extracurricular science education was made. Its topic is Expedition Tracing Invertebrates in Human Habitats.
