Proposals of Practical Excercises in Zoology Based on Protists and Invertebrates from Freshwater Aquaria
Talavášková, Barbora ; Mourek, Jan (advisor) ; Říhová, Dagmar (referee)
This thesis deals with proposals for practical exercises using freshwater aquaria in teaching elementary schools and junior high schools that focus on protozoa and invertebrates. The main aim of the thesis is to propose practical exercises using elements of inquiry-based science education. Using identification cards of protozoa and microscopic invertebrates, pupils can learn about these organisms during laboratory exercises with microscopes. A total of fourteen cards with representatives of protozoa, invertebrates, algae and cyanobacteria typical of freshwater aquariums are presented. Each of the identification cards contains a basic description, as well as a procedure for the pupils to observe and draw the organism. They are accompanied by a photograph, a pen drawing and a QR code that links to a video of the observation of the representative under the microscope. Another proposal is a practical exercise focusing on the food chain of standing water. Also included is a worksheet focusing on independent laboratory work by students on water quality analysis using the Pasco laboratory technique. The contribution of this work is the actual experience of setting up a school freshwater aquarium. The process of setting up the aquarium and investigating it is described in this thesis. The succession of...

Kdo je boss teď? aneb dopad farmaka sertralinu na hierarchii raků
MAREŠ, Josef
Pharmaceuticals' pollution of open waters is a current threat to aquatic organisms. The development of pharmacies and increased consumption of drugs leads to a burden on the aquatic environment with dangerous pollutants. Due to the fast and stressful lifestyle, the consumption of antidepressants increases significantly in the majority of the human population. After consumption and excretion, antidepressants and other drugs enter groundwater and surface water through wastewater treatment plants, which can have a secondary effect on non-target organisms. This master thesis assesses the possible impact of the commonly used antidepressant sertraline on the mutual social behavior of marbled crayfish (Procambarus virginalis). The experiment was based on monitoring the behavior of different pairs of different crayfish. The created dyads assessed mutual interactions between control crayfish, crayfish exposed to sertraline, and reciprocally between both crayfish groups. Three weeks before monitoring, crayfish were exposed to an environmentally relevant sertraline concentration of 1 g?l-1. The results were evaluated by sensory assessment according to available methods, and subsequently, the statistics were assessed. No group of crayfish observed showed a significant difference in behavior. Thanks to the initial phase of experiments of this type, we cannot determine with certainty from the results that sertraline does not affect the social behavior of marbled crayfish. However, along with other antidepressants, sertraline, a selective serotonin reuptake inhibitor, is undoubtedly a potential threat to the environment.

Protection of Invertebrates in Legal Regulation of European Union
Chlup, Petr ; Žákovská, Karolina (advisor) ; Stejskal, Vojtěch (referee)
266 Protection of Invertebrates in the Legal Regulation of the European Union Abstract In recent years, studies on the population trends of insects and other invertebrates reported widespread declines most pronounced in intensely developed regions, such as Europe. The likely causes include various activities of the industrial society, including agriculture, urbanisation, forestry, and commercial fishing. Most of these activities are governed by, inter alia, legislation on the EU level. This thesis argues that even though there are no completely white spaces in the EU law and relevant legislation addresses most of the important areas of invertebrate conservation, the current legislation is not comprehensive and inclusive enough. The arguments for this conclusion are derived from the analysis of the current EU legislation in the face of the biological context of invertebrates. In Part I, the contextual framework for the analysis is built up by outlining the presented problem of declining invertebrate populations. A short introduction to the taxonomy and ecology of invertebrates is followed by a summary of the environmental threats they currently face. The threats are matched to the corresponding EU legislation, thereby laying out the structure of Part II. The second part includes chapters on the relevant...

Breeding of invertebrates and their use in school teaching
Farionová, Jana ; Hanel, Lubomír (advisor) ; Říhová, Dagmar (referee)
The submitted Bachelor thesis has a retrieval character. It focuses on general characteristic of the selected groups of the Invertebrates and also on its breeding, which is suitable for home and school environment. The handled topic relates to my subject of study, it includes the guide, the possibilities of breeding of the Invertebrates and the selected species. It can be used by the teachers, but also pupils and students of Biology. Some parts are also dedicated to the basic elements to which is important to pay attention during the lessons and which can be well observed on the organism. The introduction concentrates the brief characteristic of the Invertebrates, it includes the list of used terms and it generally informs about the principles of breeding. The following chapters consist of the characteristic and breeding of the selected species, examples of the suitable variets and also the problem issues, which can appear during the breeding. With the described species we can also find the options how to use them during the education at school. Picture are attached in the thesis. KEYWORDS Invertebrates, charakteristic, breeding, species

Communities of protists and invertebrate animals in freshwater aquaria and possibilities of their use in teaching
Hásková, Barbora ; Mourek, Jan (advisor) ; Hanel, Lubomír (referee)
This bachelor thesis focuses on the hidden but very diverse community of protists and microscopic invertebrates in freshwater aquaria. Samples of these micro-organisms were obtained from microscopic slides submerged in aquaria for several weeks. The main output of this thesis is a multimedia didactical atlas of characteristic protists and invertebrates inhabiting freshwater aquaria. In total, eleven members from two phyla of protists and six phyla of invertebrate animals are presented using own original micrographs and short videosequences. The atlas was prepared in two forms - a text document and a web page. Potential of the atlas for use in biology teaching and extracurricular education is discussed. Key words: zoology, protists, invertebrates, teaching, didactics, communities

Flow cytometry and its use for study of insects
Stuchlíková, Magdalena ; Janšta, Petr (advisor) ; Sadílek, David (referee)
Flow cytometry is a modern technique in research, playing a significant role in biomedicine and botanics. Despite its benefits (speed, simplicity, low costs), flow cytometry is currently not used in the study of insects on a large scale. This thesis gives an overview as to how flow cytometry is used in research on insects and summarises the results of such study. This pertains to genome size and its connections to other phenomena. Other focal points of research, such as ploidy and base pair ratios, are addressed to a lesser extent. Key words: flow cytometry, use in study of insects, genome size, ploidy, invertebrates

Biodiversity of green roofs
Matoušková, Kateřina ; Sedláček, Ondřej (advisor) ; Šípek, Petr (referee)
Green roofs offer interesting multifunctinaly solutions to many problems at once. In a small area they bring benefits to people and nature. They thermally insulate buildings, improve the local microclimate and reduce the city's heat island efect. Green roofs improve air quality and also help retain water in the landscape. In combination with solar panels and retention tanks, green roofs can contribute to the modern trend of building green - sustainable - buildings. Green roofs can be used for growing food sources and for relaxation as well. Wild plants can spontaneously colonize green roofs and thereby expand their habitats in cities. The plants create habitats for many animals (especially invertebrates) and provide nectar sources to pollinators. Except food habitats, they offer birds habitat for nesting and resting place during their migration. The aim of this thesis was to evaluate the contribution of green roofs to urban biodiversity. At present, howewer, most scientific studies deal with the advantges of green roofs in connection with enviromental protection or the technical side. A small part of the studies examines the biodiversity of green roofs. My goal was to find out which factors influence a biodiversity of green roofs the most and to design an ideal roofs solution with the greatest...

Pažitková, Petronela
The following bachelor thesis with the topic: ,,Non-native invertebrate fauna of tropical and subtropical greenhouses in botanical and zoological gardens of the world and Czech Republic – review“ is concentrating on summarization of found researches, parrticularly in Czech and Slovak Republic, after that their brief comparison with some european and other countries of the world. The thesis is divided into four main sections. In the first section is a further explanation of basic concepts related to our thesis and a short characteristics of the most significant invertebrate groups. The following section is focused on the surveys that were done in botanical and zoological gardens mainly in Czechia and Slovakia, in short, foreign researches are also mentioned. Additionally, the following section is devoted on the measures againts the invasions and it also asks a question, if these species may be somehow useful. In the last section, we have compared these surveys with each other. We can observe a regularity of the occurence of some species, or on the other side, rare findings within the regions.
