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.

Stanovištní podmínky výskytu drobných zemních savců v lesních ekosystémech Moravsko-slezských Beskyd
Těšík, Jindřich
The research was focused on the evaluation of habitat differences in the communities of small mammals of different habitats in the Moravian-Silesian Beskid Mountains. In the years 2007-2015 pitfall traps caught 4 819 individuals from 16 species. Small mammals were acquired on 38 permanent research plots. The results described the influence of stand conditions (species, canopy, herb, soil conditions), climatic factors (humidity, temperature), links to typological units (forest typology, edaphic categories, forest vegetation types) and management (commercial forests, protected areas) on small vertebrates. Small vertebrates were influenced by dominance, species diversity and evenness, degree of canopy cover and herbal species. The results were obtained by statistical methods. This study determined the environmental conditions affecting the appearance of yellow-necked mouse, wood mouse, bank vole, common shrew and pygmy shrew.
