Bottled versus tap water: factors influencing drinking water
Bayer, Jakub ; Bártová, Jiřina (advisor)
This study compares factors influencing tap drinking water compared by those enviromental factors affecting bottled water. Local village water well is compared by bottled water Dobrá voda. Problems are supported by worldwide background research evaluating bottled water contamination and toxic substances leach from plasticizers. This comparaion weights possible contaminants of tap water and bottled water drawn from alike hydrogeologic regions. Borehole in Bilsko village and bore Dobrá voda is located in similar hydrogeologic area supossing identical composition of soil and therefore similarity in water mineral and toxic content. Data obtained from others studies are evaluated with respect to our own findings. Aim of the study is a review of current trend and circumstances affecting consummation of bottled water in the household.

Beech and spruce forest stands conditions in the area of the Moravian-Silesian Beskids and soil zoocenosis
Bayer, Jakub
Soil epigeal fauna of beech and spruce forest stands had been monitored for 8 years (2007-2014) in 37 selected research area in the Moravian-Silesian Beskids. Collection of material carried out twice per year in spring and autumn aspects. Site characteristics of research localities were characterized by high variability while 4 vegetation altitudinal zones, 8 edaphic categories and 12 forest site types had been distinguished. Soil fauna was extracted by Tullgren devices. Within the monitoring, 11 target animal groups were engaged in: mites, springtails, larvae stages of ground beetles, symphylans, diplurans, proturans, centipedes and millipedes, larvae stages of rove beetles, adults of rove beetles, earthworms, larvae stages of click beetles (wireworms). Earthworm´s and wireworm´s cenosis were deterimined into species and genera, respectively. Remaing groups of soil fauna had been studied within larger systematic categories. Subsequently, abundance and dominance of the particular groups of soil epigeal fauna. The outputs had been compared each other and potential relations between particular animal groups to the specific site properties, vegetation altitudinal zones, edaphic categories and forest site types had been assessed thereby. Overall, 274 015 individuals were captured within the monitored soil animal groups. Several groups of soil cenosis were disvored specific relations to the site conditions. Additionally, 12 species of earthwomrs were distinguished while Dendrobaena octaedra seemed to be significantly dominant species representing 68,33 % of total earthworm´s species spectrum. Larvae stages of wireworms were determined into 5 genera. Representatives of Athous genera formed almost 86 % of the population of wireworms.

Půdní fauna bukových a smrkových porostů v modelovém území Moravskoslezských Beskyd
Bayer, Jakub
Spruce and beech underbrush soil fauna in model territory of the Moravian-Silesian Beskids was monitored in the years of 2007 till 2012. Material withdrawal took place annually on 37 research areas in the period of spring and autumn aspect from the section situating in the massif Spruce, Knehyne and the Celadenky little river valley area in Podolanky. Several types of soil animals were investigated within this monitoring: collembolans, acarids, diplurans, myriapods and millipedes, thousandlegs, hemimetabolas, prongbucks, bugs, weevils, snout beetles, larvae, dung worms, larvae two winged, earth worms, further imaga and larval stages of rove beetle and snapping and spring beetle family. Their number was reduced for final elaboration and processing. The type determination has been realized at the earthworm family. Other above mentioned animal types have been evaluated abreast of higher systematic units. The Tullgren method has been used for soil animals' extraction from withdrawn soil samples. On the basis of substitution of particular observed and investigated soil animal types evaluation their abundance eventually their dominance has been reckoned and calculated. Subsequently these outputs and results have been compared within individual categories and potential relationships to soil surroundings, forest vegetation rates respectively forest types groups have been derived.
