Zoos as socially constructed institutions in changing social and territorial contexts
Nekolný, Lukáš ; Fialová, Dana (advisor) ; Šantrůčková, Markéta (referee) ; Boltižiar, Martin (referee)
This dissertation deals with research of the zoo as a social construct, which in its history and form represents the development of the relationship between society and nature, or man and animals. At the same time, it is a specific cultural landscape reflecting other changes in paradigms and needs in society. The current form of zoos has always reflected various economic, political, environmental and cultural aspects, or opinion and spatial changes of society. This work is a contribution to the discussion of the application of thematization typical of contemporary experience-oriented society. The aim of the thesis is to characterize the development of zoos and their current form in Europe, where this concept originated at the turn of the 18th and 19th centuries, and to discuss regional differences regarding the different geographical context of the post-socialist space. From the geographical point of view, this is a topic rarely addressed so far, both from a theoretical (the zoo as an example of the specific landscape) as well as a regional approach. The first part provides a theoretical framework by means of a discussion of scientific literature and formulating the starting points of the research based on selected concepts and paradigms (social constructivism, the relationship between man and...
Design and implementation of a control unit for the aquarium environment
Petrák, Lukáš ; Formánek, Martin (referee) ; Krejčí, Petr (advisor)
This bachelor thesis deals with the design and implementation of a prototype control unit for controlling the internal environment of an aquarium. The aim of this work is to create a device that will control the aquarium lighting using available LED strips of different colors, as well as maintain the aquarium water temperature within the range set by the user. It will then record on an SD card the progress of the lighting, the water temperature from the three sensors and the time when these values were obtained. These measurements can be retrieved and the device can be controlled via a web interface from a standard browser. The device should realizable from commonly available modules and components and its parameters should satisfy both the beginner and the advanced aquarist who, from the analysis of the measured values of the aquarium's internal environment, will adjust the control unit according to his needs.

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...
