Zhodnocení přirozeného generativního zmlazení borovice kleče v NPR Praděd (CHKO Jeseníky)
Pálka, Ondřej
This diploma thesis deals with the study of the current capability of the generative reproduction of dwarf pine stands (Pinus mugo Turra) in NNR Praděd and the determination of factors influencing the success of generative reproduction. The work deals with the occurrence of the dwarf pine seedlings depending on the stand disturbance of grass-herb vegetation, distance from parental stand and the thickness of the soil horizon A. The work also solves the problem of influence of a particular species of grass-herb vegetation on the occurrence of seedlings. The results show that the higher the rate of disturbance and the smaller the distance from parental stand, the higher is the occurrence of seedlings. It was also found that the most common types of vegetation in which the seedlings were grown were Nardus stricta and Avenella flexuosa.

The impact of vertical distribution of zoobenthos in a pond in response to the biomass stocking of carp ponds
VÁLEK, Pavel
The impact of vertical distribution of zoobenthos in a pond in response to the biomass stocking of carp ponds was tested in the Rod, Dobrá Vůle, Pohořelec, Haslauerteich and Neuteich ponds. Except for the Rod pond, various carp biomass was represented in all ponds. Sampling was conducted during the growing season (June and July), and outside the growing season (September). Physico-chemical parameters of water were measured for each sample. All samples were sorted by groups, counted and weighed. The results are presented in graphs. Zoobenthos density of the Dobrá Vůle, Haslauerteich and Neuteich ponds showed a rising tendency towards deeper parts of the pond sediment. The density of these ponds reached the maximum values in depths of 10-14 cm. This tendency was observed in the occurrence of midges in these ponds. The highest density of midges was observed in the Haslauerteich pond (1,687 individuals per square metre). The above-mentioned ponds were stocked by the common carp (K2-3). The largest density of the tubifexes in the Dobrá Vůle, Haslauerteich and Neuteich ponds was observed during the September sampling in the shallow parts of the sediment (0-6 cm). The maximum density was 1,031 individuals per square metre. On the Pohořelec pond, the occurrence of zoobenthos during both samplings was recorded only in the depth of 10-12 cm. Other representatives of zoobenthos were present in the Rod, Haslauerteich and Neuteich ponds. Larvae of Sialis and Chaoboridae were observed as well. The density and biomass was greater in the September sampling. We have noticed a greater settlement in various depths. Their maximum density was in the Haslauerteich pond (218 individuals per square metre).

Makrozoobentos zarostlého a volného bahnitého litorálu kaprových rybníků
KAJGROVÁ, Lenka
The aim of the study was to evaluate the quantitative composition of benthic invertebrates in the littoral zone with emeragent plants and outside the macrophyte beds. For these purposes, two carp ongrowing ponds were selected in the Czech Republic (Blatná region) with traditional carp (Cyprinus carpio) farming and two organic ponds in Austria (Waldviertel). Samplings were performed in monthly intervals (May - September 2018). Samples were taken from the area of open water (pelagial) and from the littoral zone. The evaluation of benthic macroinvertebrates was supplemented by in-situ monitoring of basic parameters of the aquatic environment, granulometric score and rating of organic substances in the bottom sediment of ponds, both in the pelagic and littoral zone. For the sampling of pond macroinvertebrates associated with the root system of the hard emergent vegetation, a core sampler was chosen that penetrates the roots of hard littoral vegetation. After the samples were processed (collection and weighing) in the laboratory, the organisms were divided into three groups - Chironomidae, Oligochaeta and Varia. The results were presented in graphical form. Regarding results of environmental conditions of the studied ponds, they did not differ significantly. According to the analysis of the data, macroinvertebrates density was higher in organic fish farming ponds than in traditional fish farming ponds. In the litoral zone, the average density of benthic invertebrates was higher than in the pelagiac zone. The biomass of aquatic macroinvertebrates on average was also higher in the littoral zone.

Using phototraps to the counting of wildlife animals
Hnízdil, Aleš ; Ježek, Miloš (advisor) ; Peterka, Tomáš (referee)
The subject of my Bachelor Thesis was verification of wildlife census methods by using
phototraps in region of Doupovské Mountains and Bohemian Forest. Many of the
organizations that are involved in these methods should bring a solution of this problem. This
topic is discussed in management of wild animals for more than 40 years. This thesis should
help to look at the wild animals monitoring from a different point of view. For this research
were used 21 phototraps and evaluated 20 106 pictures. Information were processed in MS
Excel. The data build a basis for animals density evaluation. Results show the adequate
number of phototraps in the area in duration of 6 weeks brings more significant results.

The influence of physiotherapy on patients with osteoporosis
REJŽKOVÁ, Olga
The theoretical part poses challange of osteoporosis as a disease that is in the limelight in recent years. Since it is a disease that causes bone rarefaction and bone stock loss was part of the work devoted to themes of microscopic and macroscopic structure of bone, bone formation and development, factors affecting growth and bone remodeling. Furthermore, the theoretical part describes the different types of osteoporosis, defines the causes and risk factors of disease, informs about modern methods and treatment procedures and establishes important principles for prevention. This work also focuses on the diagnosis of disease, particularly it is centred on the clinical and X-ray studies, osteodensitometry and laboratory tests which are currently the most frequently used methods of diagnosis. The examination procedures were discribed in detail in section operating methodology of research that were later used in the actual researches. They were especially densitometry imaging method that was used to determine bone density, followed by laboratory tests by means of them were detected samples of blood levels for substances that affect bone metabolism. To evaluate muscle strength and shortened muscle groups are used methods by prof. MUDr.Vladimir Janda, DrSc. Furthermore, the assessment of spine development, character and poise along with examination of stability were evaluated according to Romberg. The invertigate was composed of four patients. Two of them were involved in regular physiotherapeutic exercises, the other two were treated only with medicaments.
