Ontogeny of soldier behaviour and its polyethism in termites
Homolka, Petr ; Šobotník, Jan (advisor) ; Frouz, Jan (referee)
The presence of soldier caste is an important synapomorphy of group Isoptera. The adaptation of this caste to defense tasks is more than obvious and some of their morphological or even behavioral adaptations can be quite impressive. The polyethism in termites is relatively well known inbetween rather worker caste. If there are such a studies pointing at polyethism in soldiers, they are connected with soldier polymorphism. The morphological differences are of course important stimulus to role separation. The goal of this thesis was to examine the polyethism in the species of the termite with monomorphic soldiers - Prorhinotermes simplex. I did behavioral experiments with it in enclosed arenas, recorded on specific days. The data shows, that there are differences inbetween individuals and it would be benefical to invest further time to subsequent studies. The thesis bring out new point of view to defensive behaviour of termites and suggests, that even termite species without polymorphic species may have soldiers with different tasks. Besides I managed to map ontogeny of soldier behaviour in the first two weeks after moulting from presoldier instar.

Automated monitoring of behaviour as a new paradigm in the research of depressive disorder
Revayová, Anna ; Valeš, Karel (advisor) ; Kubik-Zahorodna, Agnieszka (referee)
The rapid antidepressant effect of ketamine changed the direction of the research of potential antidepressants and its effect was also evaluated in this thesis. However, the main focus of this thesis is a new methodological approach to the research of depressive disorder. The main interest lies with the evaluation of automated monitoring of behaviour in this research. The first aim of this thesis was to evaluate the antidepressant effect of ketamine in the forced swimming test using software enabling automated monitoring of behaviour. The second aim was to meassure the change in phosphorylated Mammalian target of rapamycin (mTOR), using Enzyme-Linked ImmunoSorbent Assay (ELISA). The last, but the most important aim of this thesis was to implement the utilization of Phenotyper boxes in the automated behavioural evaluation of the olfactory bulbectomy model of depressive disorder and also evaluate the effect of ketamine in this model. Ketamine did not show an antidepressant effect in forced swimming test, however this observation could be influenced by chosen dose and mouse strain. Sensitivity of the test to chosen experimental protocol shows insufficient validity of this test. Observed change in level of phosphorylated mTOR corresponded with the behavioural results. Data collected from Phenotyper...
Influence of external conditions on egg incubation in lapwings (genus Vanellus) in temperate and subtropical climate
Pešková, Lucie ; Šálek, Miroslav (advisor) ; Hořák, David (referee)
During incubation, most birds require the presence of at least one parent to ensure suitable incubation conditions for embryo development. The main factors that affect the development of the embryo are temperature, humidity and egg turning. In this work, incubation conditions were investigated in two biparental Lapwing species (genus Vanellus), the Northern Lapwing (Vanellus vanellus), which faces the risk of egg cooling in temperate areas, and the Red-wattled Lapwing (Vanellus indicus), which faces the risk of egg overheating in the subtropics. A laboratory experiment testing the thermal properties of the Red-wattled Lapwing nest lining showed that it selects lining material that slows down temperature growth during egg heating, thus ensuring suitable thermal conditions during parental absence at high ambient temperatures. Temperature and egg turning during incubation were recorded by an artificial egg with a built-in sensors placed in the nests of both target species; data collected by the sensors were stored by a base-station located nearby. The average egg temperature was 32.5 řC for the Northern Lapwing, and 35.0 řC for the Red-wattled Lapwing. Egg temperature in both species fluctuated significantly, affected by many factors. Egg temperature increased with increasing ambient temperature, it...
Coach behaviour in training process
Vachuta, Lukáš ; Buzek, Mario (advisor) ; Frýbort, Pavel (referee)
Name:Coach Behaviour in Training The Aim of the Thesis: Observation of the trainer's attitude to the supervision of the youth football team. The observed object will be the trainer Martin from the club Bohemians 1905. I will focus my attention on his behaviour to players, on the ways how he explains individual exercises, in particular on his way of communication with children, understandability and clearness of the demonstration. I will also watch the ways used for motivating the trainees. Methodology: To reach my result I will use two basic methods. The first method deals with observing and making video recordings which will be consequently analysed and evaluated. The second method will be based on questioning both the trainer and the chosen players using a short questionnaire. Results: My thesis will serve as positive and negative feedback for the observed trainer who can use the provided material with particular recommendations in order to improve his work. Further, the mentioned recommendations can be used by all trainers involved in youth categories as it is material which can help them with the procedure of explaining and supervising exercises. Key Words: children, adults, junior school age, behaviour, sport psychology, respect to rules
Lachrymal secretion in tenrecs: physiological, behavioral and phylogenetic contexts (Tenrecinae, Afrosoricida)
Bálek, Jiří ; Horáček, Ivan (advisor) ; Sedláček, František (referee)
The secretion of white liquid around the eyes and nose with a spiny tenrecs Echinops telfairi and Setifer setosus mentions for the first time Poduschka in 1974, but until now this phenomenon in these species no one paid any detail. Similar secretion was described in Mountain beaver or by shrews. The impetus for shedding the excitement caused by the presence of an individual female or another male or its odor. Males secretions also used for marking territory. A total of 70 samples of eye secretions from ten male Echinops telfairi during the entire active season (from March to October) have been collected within this study. For protein detection method was used two-dimensional polyacrylamide gel electrophoresis (2D PAGE) and subsequent identification by mass spectrometry. An autopsy of the eye area was performed for representatives of all four genera of the subfamily Tenrecinae (Tenrec, Setifer, Echinops, Hemicentetes), died in Pilsen Zoo. It was found that a) species of pinholes that produce ocular secretions are significantly higher tear and Harder's gland, b) secretions contain lipocalins - proteins with the ability to transmit pheromones and other hydrophobic molecules, c) secretions of the orbital region having a different composition than the secretions from the nasal area (significantly lower protein...
Attitudes competitors kickboxing coach to lead the way during the match
Oralová, Iva ; Pavelka, Radim (advisor) ; Venzara, Jan (referee)
Title: Attitudes competitors kickboxing coach to lead the way during the match Objectives: The main objective of this study is to examine how athletes perceive their coach in leadership (coaching) during the match, whether this behavior coincides with their preferences and what attitudes they have. Furthermore, these results are interpreted as a feedback to coach who lead a match to the increase effectiveness of its leadership and also show that perception during the match and athletes's preferences are very individual and different. And therefore coaches should not follow just generalized research into coaching but they should work with each athlete individually and according to theirs specific needs. Methods: In this thesis were used a method of structured questionnaire and semiguided interview. The structured questionnaire was used in the detecting method of coach leading during the match and preferences of participants. The semiguided interview method was used to specify preferences and attitudes towards a method of coach leadership. Results: It was find out It was found that the differences between preferences and the perceived reality occur not only for individual athletes, but also between them. It turned out that there is some consensus, as in the perception of coach's behavior during the...
Social organization and communication of flying foxes focused on the genus Rousettus
Vašíčková, Pavla ; Jahelková, Helena (advisor) ; Lučan, Radek (referee)
Within the family Pteropodidae there are different types of social systems, depending on the species. Reproductive activity of Egyptian fruit bat (Rousettus aegyptiacus) is based on the latitude, when in milder latitudes individuals tend to be seasonally monoestry, southerly living individuals are less synchronous. Gestation lasts about four months and in most cases one young is born and mother cares about it. Egyptian fruit bats often inhabit caves, while there may live thousands of individuals and even more together. Pteropodidae are focused on plant food, which they choose according to the many criteria. Members of the genus Rousettus belong to the food generalists and their diet includes trees and herbs, from which they consume fruits, flowers, nectar, pollen, shoots and leaves. They were also observed by eating beetles of the family Scarabidae. Flying foxes of the genus Rousettus are special, because they orient by echolocation. They emit short broadband signals through the vibration of the language, whose length ranges from 50-100 s. From other chiropteran families they differ through the way of production the signals. In addition to echolocation senses of smell and sight are key in terms of communication. The smell is important mainly in attracting a partner, for mutual recognition between...
Within-group fish behaviour: effect of common experience
Fořt, Martin ; Slavík, Ondřej (advisor) ; Frouzová, Jaroslava (referee)
Recently, behavioral studies focusing on social relationships of fish in groups became popular. Fish are able individually recognize conspecifics or even heterospecifics. This ability allows distinguishing among individuals in and between groups and shows that fish prefer associating with familiar or kin individuals. An interaction with kin individuals is called condition-dependent recognition, whilst relationship based on previous experience is called condition independent recognition or familiarity. Both of these interactions can bring the participants some advantages, such as better protection from predators, foraging benefits, lower aggression levels, etc.
Nesting behaviour and population genetics of solitary bees (Hymenoptera: Anthophila)
Černá, Kateřina ; Straka, Jakub (advisor) ; Žďárek, Jan (referee) ; Paxton, Robert J. (referee)
My thesis is focused on nesting behaviour and population genetics of solitary bees. These two topics, although seemingly unrelated, bring much new information and thus contribute to the better understanding of solitary bee biology that is still insufficiently known. Although the solitary behaviour represents the necessary original state for the evolution of higher sociality or obligate cleptoparasitism, its role is largely unappreciated. Furthermore, intraspecific cleptoparasitism, which is an alternative and facultative nesting strategy in bees, is a probable antecedent state of obligate cleptoparasitism. Although the obligate cleptoparasitism is a very common strategy in solitary bees, the information about the frequency and the occurrence of intraspecific cleptoparasitism in solitary bees is rare. We studied the nesting behaviour of solitary bees to detect different behavioural patterns that could serve as preadaptations to sociality or cleptoparasitic behaviour and we also focused on the detection and description of intraspecific cleptoparasitism in solitary bees. We chose four model solitary species for these studies - Andrena vaga (Andrenidae), Anthophora plumipes (Apidae), Colletes cunnicularius (Colletidae) and Osmia rufa (Megachilidae). We described the behaviour of Andrena vaga at the...
