2	Změny struktury a funkce společenstva hub v půdním prostředí po ukončení toku asimilátů u smrku ztepilého (Picea abies) / Change of structure and function of a fungal comunnities in the soil environment after the end of the flowassimilates with Norway spruce (Picea abies) Charvátová, Markéta January 2015 (has links) The decomposition of plant biomass is associated with changes of the associated fungal community which is crucial in the process of degradation due to their production of extracellular enzymes. Moreover, fungal communities as well as enzymatic activity are specific for soil microhabitats. This thesis focused on the importance of fungi associated with the roots of Norway spruce (Picea abies) trees. Forest with dominating Norway spruce, located in the School Forest Enterprise Křtiny area in Moravia, was selected for the experiment. The aim of this thesis was to compare the community composition of fungi in the roots, rhizosphere and bulk soil and to describe the gradual development of this community after the death of the roots. The next aim was to isolate, describe and characterize those fungi that decomposed roots 5 and 9 months after tree harvest. Identification of fungal isolates was based on DNA sequencing. Degradation capabilities were determined as the activity of enzymes involved in the degradation of lignocellulose. Composition of fungal communities was described by sequencing of environmental DNA on the Illumina platform. Before the flow of assimilates from the live trees stopped, communities of ectomycorrhizal fungi dominated with 60 % of all sequences. Increased abundance of saprotrophic...
3	Případová studie rekultivace území lomu Silvestr na Sokolovsku, aneb cesta z lomu na golf / Case Study reclamation of the quarry Silvestr in the Sokolov, or the path from the quarry to golf Barteková, Petra January 2016 (has links) This diploma thesis deals with the issue of public participation in deciding activities of reclamation. I chose former quarry Silvester near Dolni Rychnov as my research area. This area was transformed into eighteen-holes golf grounds and wood grounds with sport and relax stuff during reclamation work. This thesis consist of theoretical, methodological and empirical section. Theoretical section introduce basic concept of recultivation, law regulating recultivation, conservation, restoration ecology as scientic field and last but not least Sokolov region as region with long tradition of recultivation. The Methodological part describes methods of practical research, which is essential part of this thesis. The Empirical section introduce results of my research. Key words: reclamation, opencast coal-mining, restauration ekology, nature conservation, reclamation project, expert interview, questionnaire
4	Short-term effects of controlled conservation burning Rindzevičius, Vytautas January 2014 (has links) In this study, the immediate and short term (three months) effects of conservation burning have been investigated in coniferous forests in southeastern Sweden. Five tree species were investigated Picea abies (Norway spruce), Pinus sylvestris (Scots pine), Populus tremula (aspen), Betula pendula (silver birch) and Betula pubescens (downy birch), as well as ground vegetation of mosses, dwarf shrubs and ground lichens. Burning increased the proportion of live deciduous tree shoots from 51 % to 81 % and the live tree shoot size distribution of four tree species was significantly changed by fire. Fire affected the tree species differently. Three months after burning deciduous tree species exhibited strong sprouting, while P. sylvestris had established many seedlings, significantly increasing its share of the tree stand. P. abies lacked any visible positive response to burning and its number of live shoots decreased by 83 %. Mineral soil was exposed on only the moss vegetation and covered just 4 % of the studied plot area. The initial vegetation response to fire was negative, but significant dwarf shrub recovery was detected three months after burning. forest forest fire burning nature conservation conservation Sweden fenoscandia Norway spruce Scots pine aspen Picea abies Pinus sylvestris Populus tremula Betula vegetation trees tree shoots follow-up followup boreal boreal forest ekology skog skogsbrand brand bränning naturvård bevarande Sverige fenoscandia gran tall asp Picea abies Pinus sylvestris Populus tremula Betula vegitation träd trädskott trä skott upfäljning followup boreal boreal skog ekologi
5	Hierarchie a chování člověka. BDSM jako alternativní sexuální chování. / Hierarchy and human behavior. BDSM as an alternative sexual behaviour. Jozífková, Eva January 2016 (has links) Preferences for sexual arousal by overstated dominance and submission in sex is categorized as F65.5, sadomasochism, according to ICD, but this behaviour is called BDSM among the general public. The ground of these preferences could be ultimately biological. These preferences reflect behavioural strategy which enables to gain higher reproductive success. Men and women who were sexually aroused by a submissive partner had more male relatives than men and women with other preferences. Contrary to the women, the dominant men reported themselves as more attractive. Women who were aroused by a higher-ranking partner considered themselves more attractive. Sons of couples in which was hierarchical disparity had more siblings than sons of "equal" couples or couples with no hierarchical disparity. Daughters of hierarchically disparate couples had more brothers than daughters of "both dominant" partners. Concurrently, number and gender of offspring as well as self- reported attractiveness are likely to be criteria of the reproductive success in humans. It is also interesting that hierarchically disparate couples, without regard to gender of higher-ranking partner, reached higher reproductive success than "equal" couples. Individuals who preferred higher- or lower-ranking partner were also aroused by...
