Feeding ecology of bats in the eastern Mediterranean
Žďárská, Lenka ; Andreas, Michal (advisor) ; Gajdošík, Martin (referee)
This work gives an overview of the composition of the diet of bats in the eastern Mediterranean and the Middle East, discusses the structure of bat communities in different bioregions of the area in terms of hunting strategies and resource partitioning and last but not least, how echolocation and morphological characteristics of bats affect the composition of the diet. Although some samples were relatively small therefore it is necessary to look soberly at their informative value, and thus their importance is undeniable. The study in some cases provides completely the first information regarding the composition of diet in several species. Asellia arabica mainly catches Coleoptera (Scarabaeidae), Triaenops persicus hunts Lepidoptera, but Heteroptera, Coleoptera (Scarabaeidae) and Orthoptera too, while Triaenops parvus is a specialist in hunting Lepidoptera. Rhinopoma muscatellum hunts mainly Formicoidea, followed by Coleoptera (Melolonthinae) and Heteroptera, Rhinopoma hadramauticum hunts Formicoidea. Lepidoptera of different size, Heteroptera and Coleoptera are the prey of Chaerephon nigeriae. Pipistrellus hanaki has a wide niche breadth as other species of the genus Pipistrellus. In this study Brachycera, Auchenorrhyncha and Coleoptera primarily occurred in its diet. Not yet described species of...
Analysis of photo-records of non-fish prey in the diet of selected species of fish-eating birds
Mach, Jakub ; Čech, Martin (advisor) ; Vejřík, Lukáš (referee)
Piscivorous birds are often blamed for causing significant damage to fish stocks. Various methods are used to determine the composition of their food, each of them has limits in its ability to determine the complete food spectrum. This work maps the complete food composition of 14 species of fish-eating birds with a method that is not commonly used. Method used in this work uses analysis of publicly available photos on Google.com. In addition to the complete composition of the food, the species composition of the non-fish part of the prey was also determined, and in the case of the Great Cormorant (Phalacrocorax carbo), also the length of the fishes it catches. The aim of this work is to reveal the usability of this method for these purposes. A total of 2350 retrieved photographs were analyzed. The results obtained by photo analysis are in all cases compared with data in the available literature. For representatives of heron birds (Ardeidae), the analysis of photographs provided good information on the food spectrum of individual birds and on the qualitative composition of the non-fish component. It also provided relatively good information on the diet of the White-tailed Eagle (Haliaeetus albicilla), but the bird part of the prey was slightly underestimated. In the diet of the Great Crested Grebe...

Zouharová, Marcela
This thesis deal is devote impact environment on immune systém.First part of this deal is pursue immunology as a science and take up readers with basic immunology term.After presents lymf gland and specific and nonspecific immunities. In second part of deal is addu-ced actuation impact on immunite system -inside and outer. In deal is described development of the immune system in prenatal and postnatal age. Part is devote impact of food on the im-mune systém. In outer impact is mentions heterogeneous substance like a heavy metals, my-cotoxins and stress.
Distribuce a početnost bobra evropského v povodí Veličky
Andrýsek, Martin
This bachelor thesis deals with quantity of the European beaver (Castor fiber) in the catchment area of Velička and its tributaries – the river called Kozojídka and Kuželovský stream. Determination of the total amount of territories was based on indirect observation which took place in years 2017 and 2018. All characteristics of beaver residence were recorded into GPS device and the obtained data were elaborated in GIS application. The output was determination of particular borders in each territory. Altogether four territories were discovered in 2017 (one on the Kozojídka river, one on Kozojídský stream and two on the Velička river). In the following year, one more territory on the river Velička was discovered. The total length of all territories reached 6.48 km (2017) and 7.21 km (2018).
Vliv potravy kontaminované manganem na vývoj fytofágů
Šťasta, Michal
Foreign substances (including heavy metals) enter to the food chain of the animal part of ecosystem can affect the development of organism, its mortality rate and consumed food quantity. It is depended not only on the ability to elimination of these substances influence by the organisms. The effect of the diet with differentiated levels of manganese has been studied in laboratory conditions on caterpillars Cabera pusaria (Lepidoptera; Geometridae). Laboratory breading took place in Climacell chamber with controlled temperature, humidity, and lighting conditions. Three different contents of manganese in the diet of caterpillars was achieved by dipping of birch leaves (Betula pendula) in solutions of MnCl2.4H2O. We determined the statistical significant differences between the treatments in experiment in the amount of consumed food, the time of pupation, mortality rate of caterpillars. And significant differences were detected in unconsumed food, droppings and pupae. The increased concentration of manganese in the diet had a negative influence on the development of C. pusaria larvae and it can cause 100% mortality of caterpillars.
