Contribution to Usage Postural System at Stripping Logopaedia Defects
ŠAFÁŘOVÁ, Michaela
This work focuses on the use of a postural system in logopedy (speech therapy). Based on theoretical knowledge of anatomy, kinesiology and logopedy, it explains the influence of a posture on respiration, phonation and articulation. The work mainly concerns the head region and phonatory system in connection with posture and respiration. The possibility is also suggested of incorporating the postural system into logopedic excercises in from of correct sitting position based on the so-called ?cogged wheel model?. The subject of this study was a group of five preschool children with cerebral palsy diagnosis under the care of a voluntary association Arpida in České Budějovice.

Respiration of spiders during satiation and starvation
KRAUS, Roman
I raised the young spiders breeders known species Lasiodora parahybana a stage suitable for the target work. The goal is to measure and graphically express the consumption of oxygen (O2) and record the value of spiders saturated metabolism during starvation. 37 days, I measured 20 spiders in 2 batches in Warburg respirometer. The spiders after some time has been to regulate metabolism and to the values of its viability. The resulting value is visible decrease in metabolism and weight loss.

Metabolism of B.vagans during satiation and starvation
DENKOVÁ, Adéla
The aim of the work was to introduce an extraordinary ability of Brachypelma vagans: survive some time of starvation by regulation its own metabolism to minimum. The oxygen consumption for body mass unit was measured for 576 hours for each of eleven objects. Results were placed into the tabs and graphs and were rated. During the experiment were lost four objects because of starvation and alcaly burn.

An experimental study of initial succession on different substrata: analysis of changes in plant species cover and some soil biological parameters and their relationships
KRESÁČ, Martin
A four year experimental study of initial stages of succession on different substrata (sand, peat and gray clay overburden from brown coal mining) was carried out. The substrata were transplanted into two different landscape types in the Czech Republic. Control plots were filled with autochthonous topsoil treated with high temperature vapor. Plots with un-treated autochthonous topsoil were also established. Plant species cover and several soil-biological parameters (soil microbial biomass, basal soil respiration, exchangeable pH(KCl), organic-C extractable by potassium sulfate solution, and nitrate-N content) were measured once a year. Obtained data were mainly processed by unimodal (plant cover data) and liner (soil-biological data) ordination methods. Biological species traits (life span, seed dispersal vector, seed bank type, ecological strategy type following Grime, life form following Raunkiaer) were used to characterize early stages of plant succession. Vegetation and measured soil-biological parameters, except pH(KCl), were significantly changing during four growing seasons. Variance partitioning analysis based on plant species cover data indicated the landscape type to be the main governing factor and physico-chemical characteristics of substrate to be less important during the studied initial stages of succession. The same analysis based on soil-biological parameters showed the reverse result. Great variability of plant species ecological traits was noticed during four growing seasons. The earliest plant colonizers were mainly ruderal, anemochorous terophytes with persistent seed bank. The number of species with C-strategy type increased during the study. The relationship between the average plant species cover and measured soil-biological parameters was also examined during the experimental study of early succession. Direct and indirect ordination revealed the average sum of plant species cover to be weakly positively correlated with soil microbial biomass, basal soil respiration, nitrate-N, potassium sulfate extractable organic-C, metabolic quocient (qCO2) and negatively correlated to exchangeable pH(KCl). The relationship was significant only in the case of microbial biomass and potassium sulfate extractable organic-C. More detailed studies of the relationship between aboveground plant species biomass and soil microbial communities in initial stages of succession are required. Comparability of presented study is limited because not many experimental investigations of similar kind have been presented until now.
