Postprandial thermophily in reptiles
STUCHLOVÁ, Klára
Many ectothermic vertebrates, including some species of reptiles, raise their preferred body temperature after feeding, termed postprandial thermophily. Postprandial thermophily enable the animal to digest its meal at higher rate. However, most studies documenting this phenomenon have relied upon laboratory thermal gradients, with grossly oversimplify an animal's environment and the thermal gradient data may sometimes be misleading. On the other hand, in field or field enclosure, thermoregulation is just one concern among many (such as reproduction, predator avoidance, foraging) and the current biotic and abiotic factors may influence actual thermoregulation behaviour of the specimen. So there is the need for caution in interpreting results. Future research into the thermal ecology of ectotherms should take special care in the design of experiments and methodology. Study animals should be given microhabitats that approximate those they prefer in the wild.

Influence of selected factors on reproduction of fish Ancistrus multispinnis
BARDOUNOVÁ, Alena
The white-girdled bristlenose catfish (Ancistrus multispinnis) is found in South America in the Amazon Basin, especially along the bed of flowing bodies of water. The male can be recognised from the long, thick, bristling tentacles and odontodes on the head and cheek. Females either have no tentacles or short, thin ones. Ancistrus multispinnis is omnivorous but primarily consumes plant matter. It is a much sought-after fish and it is therefore important to determine the best form of breeding and rearing. The monitoring required for compilation of the research project was performed in the aquarium room at the Department of Biological Sciences from March 2011 to March 2012. Normal and albino variants of Ancistrus multispinnis were used for reproduction. The tested fish were placed in 50 litre tanks where they then reproduced. A WTW meter, column (cation exchanger) and demineralisation filter were used for measurement of the values and for water treatment. The aim of the research project was to determine the influence of a selected form of feeding and water temperature on successful spawning of Ancistrus multispinnis. The findings reveal that, for successful spawning and breeding of these fish, the best form of feeding is to administer pellets specially designed for Ancistri, boiled nettles or lettuce leaves, finely shredded beef heart and even the occasional addition of pond plankton. The ideal water-temperature was revealed to be from 24-26 °C, pH 7-8, conductivity approx. 230 ?S/cm and oxygen content approx. 8.00 mg.l-1.

Impact of teperature, fish size and feeding on oxygen consumption and ammonia excretion in the african catfish (Clarias gariepinus)
KOMENDOVÁ, Jana
Aims of this thesis were to assesed the impact of feeding, temperature of water and fish size on ammonia excretion and oxygen consumption in Clarias gariepinus in recirculating system. Fish were divided in 8 weight categories from 21 to 2495 g. Experiments were performed under four temperatures: 22°C, 25°C, 28°C and 30°C. Fish were acclimatized, light conditions were: 14 hours of light period and 10 hours of dark period. Feeding was provided fed four times a day. Starved fish were measured. Measurements were held every two hours. Oxygen consumption was measured by multimeter and ammonia excretion using Nessler?s method. Average daily oxygen consumption in fed fish was dependent on temperature and average individual weight of fish, varied from 10.5 to 96.6 mg O2/kg/h and in hungry fish from 4.3 to 61.8 mg O2/kg/h. TAN excretion varied from 0 to 59.9 mg TAN/kg/h in fed fish and from 0 to 60.8 mg TAN/kg/h in hungry fish. Oxygen consumption increased with increasing temperature. Ammonia excretion was very unstable at all temperatures in all weight categories. Fish had higher ammonia excretion in light period of experiment.

Feeding of wild boar in hunts of Chlum and Sepekov
KOTALÍK, Tomáš
The bachelor thesis is focused on feeding of wild boar in two hunts. The first hunt which was chosen is the hunt of Chlum. The second hunt which was chosen for monitoring is the hunt of Sepekov. There were chosen two feeding places for monitoring in each hunt. The monitoring started in March 2009 and ended in February 2010. The monitoring of feeding should display differences between forest and mixed hunt. But the main reason was to find out the intensity of visits of wild boar in particular seasons pursuant to the influence of different factors. These factors were judged: climatic (snowfall, rainfall and temperature), the influences of sowing and harvest of agricultural crops during the year, the influence of collective hunting on wild boar near the feeding place and shooting on feeding places. The influence of feeding on the damages made by wild boar to fields was judged too. Localities were controlled twice a week. The feeding places were controlled by Ir-C cameras which were given on two feeding places once a week. These facts were found out by the observing. The intensity of visits on the feeding places is very different in particular seasons. The visit rate of feeding places isn´t influenced by the production of forest seeds in spring. We found out that the most favourite feed in this season was maize. Wild boar stays in agricultural monocultures in spring and on feeding places comes minimally. The popularity of particular sorts of feed depends on the term of their putting and hunting of wild boar in autumn and winter. We can avoid the damages to agricultural crops in spring, autumn and winter if we will have large enough forest in which we will be able to hold wild boar by feeding. The visit rate of the feeding place is influenced by the hunting near the feeding place, but the intensity of this influence depends on the scope of the hunting and the number of hunted members of herd which visited this feeding place. Wild boar visits the feeding place about two or three hours earlier in time of indigence. But during the rain it never appears on the feeding place.

The influence of regimen in general nurses in three-shift operation on their bio-psycho-social needs
ČAMRHELOVÁ, Veronika
The right regimen is one of the factors influencing the ability to handle the requirements of medical profession. It is important for the nurses to realize how important the right diet and keeping to it not only at home but also at work is, especially in the three-shift operation. The survey was quantitative. Anonymous questionnaires for randomly chosen nurses were applied for data collection. The research survey was carried out at asylum and at the Hospital in Havlíčkův Brod. 120 questionnaires were distributed in total, of which 114 (100%) were used for the research survey. Three goals were set for this paper. To find out whether nurses working in three-shift operation eat regularly, whether nurses keep a drinking regime and whether they suffer due to their regimen from indigestion. The set goals were fulfilled in the paper. Three hypotheses were set, each of which related to one goal. The first hypothesis presumed nurses ate regularly. This hypothesis was not confirmed. The second hypothesis presumed nurses maintain drinking regime at work, which was confirmed. The third hypothesis presumed nurses do not suffer from indigestion due to their regimen. The survey has shown nurses believe the medical profession has an impact on their regimen, especially in irregular eating habits, lack of sleep, and besides they consider their work as the cause of stress. On the other hand the nurses maintaining of drinking regime and lack of indigestion problems was a surprising realization. Regular eating habits certainly are an indicator of regimen. However many nurses do not have regular eating habits. The results of the paper shall help to better understand the importance of the right regimen. Nurses should be acquainted with this issue.

Noise in the vicinity of farms for rearing calves.
ŠÁMAL, Jiří
The work deals with noise in the vicinity of farms for rearing calves. In this work addresses the size of the noise that affects animals and humans around them. Data collection were two sound level meter, which we recorded the noise. Values are summarized in graphs. From graphs is clear, that there is overturned hygiene standards. This is reason, why there is no need to propose changes.

Employees´ Amenities from the Accounting and Tax System Perspective
PAPOUŠKOVÁ, Jitka
The bachelor thesis deals with employees´ amenities issue. Employees´ amenities belong to the inseparable instruments of contemporary management of human capital. Employees´ amenities affect positively employees´ contentment. Furthermore, they restrain fluctuation, encourage loyalty and motivate to higher and better performances. The goal of this thesis was to characterize employees´ amenities, their historical evolution and main meaning. The thesis was also focused on survey of the most known employees´ amenities and their tax perspective from the employees´ and employers´ points of view. The practical part was focused on analysis of employees´ amenities which are provided in labour-law relations. A conducted survey showed how employees perceive their amenities, if they use them, are satisfied with them or if they prefer other amenities. The survey was realised in the JIP {--} Papírny Větřní, a. s. company and other companies of the Czech South territory as well so that the comparison of the survey was enabled.
