Invertebrates indicative of seagrass meadows with a focus on molluscs.
Koucký, Václav ; Juřičková, Lucie (advisor) ; Petrusek, Adam (referee)
Seagrasses are angiosperms adapted to life in a marine environment, forming growths in coastal waters of all continents except Antarctica. Seagrass growths constitute ecologically important, highly productive ecosystems. Seagrasses are relatively rare in the fossil record due to their low fossilisation potential. To study distribution and other characteristics of this important ecosystem in the geological past, we need to be able to identify seagrass growths by using indirect indicators such as molluscs. From the available information, we can gather, that among molluscs there are several good seagrass indicators, but none are infallible and universally applicable. To infer seagrass growth presence in the absence of seagrass macrofossils we must utilize all information available at a given site.

Learning with Elements of Inquiry-based Science Education Focused on Invertebrate Animals of the School Garden for Pupils of the 2nd Grade of Primary School
Sedláčková, Denisa ; Svobodová, Silvie (advisor) ; Říhová, Dagmar (referee)
The thesis delves into teaching with elements of inquiry-based education, with a focus on invertebrate animals in the school garden environment. The theoretical section addresses the instruction of invertebrate animals at the 2nd level of primary school, characterizing representatives commonly encountered by students in the school garden. Simultaneously, it identifies the potential of the school garden for natural science education. This section also describes activating teaching methods to be implemented in the proposed educational program. The practical part of the thesis thoroughly explores the design of an educational program with an emphasis on investigative elements. This program includes the production of tools for collecting and capturing invertebrate animals, such as creating insect hotels, beetle traps, and pitfall traps. The thesis also meticulously examines the practical utilization of various tools for identifying captured invertebrates. The proposed educational program has been carefully implemented and subsequently thoroughly verified in practice. In the research section of the thesis, a systematic study was conducted using pretests and posttests to examine the impact of the applied educational program on changes in students' knowledge and attitudes towards invertebrates.

Evaluation of the currency of source information for CITES organisms on the Species+ web platform
KORCH, Martin
The aim of the work was to assess the existence and timeliness of CITES standard references for CITES animals on the Species+ web platform. Among the most neglected groups in Invertebrata were Mollusca, Arthropoda and Echinodermata, where 30 references (14%) were missing from the total number of species included. As for the Vertebrata, it was the group of Elasmobranchii and Reptilia where 276 references (20%) were missing from the total number of species included. Most of the available references were published more than 10 years ago. The number of unique references was much higher in Vertebrata than in Invertebrata. The most recent references are currently for Cnidaria, Echinodermata, fishes (Actinopteri, Dipneusti and Coelacanthi), Elasmobranchii and Amphibia and, in general, species included in Appendix II.

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...

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
