Usage of dissection of invertebrate animals in education of biology at secondary school
Ondrová, Radka ; Mourek, Jan (advisor) ; Říhová, Dagmar (referee)
The thesis is focused on anatomy and implementation of dissections of 4 selected model invertebrates in school practice. The selected model species include swan mussel (Anodonta cygnea), stick insect (Medauroidea extradentata), cockchafer (Melolontha melolontha) and sea urchin (Echinus esculentus). In case of the cockchafer, the text is based on this model species, but the supporting photographs of dissection are taken from the tropical cetoniid beetle Pachnoda, which has very similar internal anatomy with the cockchafer. For all selected animals, I describe external and internal morphology as well as recommended methods of obtaining the material, proper killing of specimens, and dissection techniques. The text is supplemented with original digital macrophotographs. The thesis includes also an overview of primary and secondary school textbooks with focus on anatomy of the selected animals. The text is supplemented by a glossary of morphological terminology used in this thesis. Attached is a photographic atlas of dissections, which is a combination of this master thesis and my bachelor thesis (defended in 2010), in which I dealt with five model invertebrates in the same way. This is Ascaris suum, Lumbricus terrestris, Helix pomatia, Procambarus aff. fallax and Archimandrita tesselata. The complete...

Výhodnocení úspěšnosti obnovy lesa na požářišti Bzenec
Zemčík, Petr
The aim of this thesis was to evaluate successfulness of forestation at a seat of fire near Bzenec. Several types of planting stock varying in the type of species, plant cover, the way of growing and coverage by surrounding growths after planting were used. Two independent measurings were taken, during which shoot height, root crown thickness, growt length, losses, vitality, diversion from vertical, trunk straightness, damage by biotic agents (mainly by forest cockchafer), the weight of dry matter and root deformations were investigated. The paper strip method executed by a rotary cultivator proved to be little effective, because cockchafer grubs were not affected in any way when the soil was prepared this way. Big losses were found out already during spring evaluation. These losses doubled, even tripled, during a vegetation period. The losses were caused mainly by cockchafer grubs. It is possible to recommend suitable forestation of weeded areas by containerized planting stock of pine and bare-rooted broad-leaved trees as a possible solution.
