    Vertical and horizontal variation of carbon pools and fluxes in soil profile of wet southern taiga in European Russia

    Get PDF
    Vertical and horizontal distributions of soil organic carbon, potential microbial activity and basic soil properties were studied in a boreal mixed forest (Central Forest Reserve, TVER region) to elucidate whether the soil CO2-efflux is related to basic soil properties that affect the C pool and activity. Soil cores (0–100 cm depth) were taken from two transects every 50 meters (44 points) immediately after completion of soil CO2-efflux measurements. Soil was separated into layers and moisture, bulk density, root density and bacterial counts were determined within one day after soil was taken. Microbial respiration, biomass, CN contents and pH were measured within few months. The variability in the soil CO2-efflux and microbial activity was mainly explained by soil bulk density. Results further indicate that laboratory measurements of microbial respiration can represent heterotrophic soil respiration of a distinctive ecosystem in natural conditions, if microbial respiration is measured after the effect of soil handling disappears

    Linking microbial diversity and functionality of Arctic glacial surface habitats

    Get PDF
    Distinct microbial habitats on glacial surfaces are dominated by snow and ice algae, which are the critical players and the dominant primary colonisers and net producers during the melt season. Here we have for the first time evaluated the role of these algae in association with the full microbial community composition (i.e., algae, bacteria, archaea) in distinct surface habitats and on twelve glaciers and permanent snow fields in Svalbard and Arctic Sweden. We cross-correlated these data with the analyses of specific metabolites such as fatty acids and pigments, and a full suite of potential critical physico-chemical parameters including major and minor nutrients, and trace metals. We show that correlations between single algal species, metabolites, and specific geochemical parameters can be used to unravel mixed metabolic signals in complex communities, further assign them to single species and infer their functionality. The data also clearly show that the production of metabolites in snow and ice algae is driven mainly by nitrogen and less so by phosphorus limitation. This is especially important for the synthesis of secondary carotenoids, which cause a darkening of glacial surfaces leading to a decrease in surface albedo and eventually higher melting rates.

    Microbial diversity in waters, sediments and microbial mats evaluated using fatty acid-based methods

    Get PDF
    The review summarises recent advances towards a greater comprehensive assessment of microbial diversity in aquatic environments using the fatty acid methyl esters and phospholipid fatty acids approaches. These methods are commonly used in microbial ecology because they do not require the culturing of micro-organisms, are quantitative and reproducible and provide valuable information regarding the structure of entire microbial communities. Because some fatty acids are associated with taxonomic and functional groups of micro-organisms, they allow particular groups of micro-organisms to be distinguished. The integration of fatty acid-based methods with stable isotopes, RNA and DNA analyses enhances our knowledge of the role of micro-organisms in global nutrient cycles, functional activity and phylogenetic lineages within microbial communities. Additionally, the analysis of fatty acid profiles enables the shifts in the microbial diversity in pristine and contaminated environments to be monitored. The main objective of this review is to present the use of lipid-based approaches for the characterisation of microbial communities in water columns, sediments and biomats

    Téma mé bakalářské práce zní Šperk pro... Vybrala jsem si pro své zpracování tématiku hry, pohybu a skládání. Tyto témata jsou mě velice blízké. Základem pro mou práci bylo vytvořit si systém, který by umožnil pohyb jednotlivých komponentů. Dále vytvoření jednotlivých segmentů a jejich kompletace dohromady. Každý šperk působí velmi hravě a pohyblivě. Materiál použitý pro práci je mosaz a ocelové dráty. Kolekce šperků má podnítit ke hře s nimi. Zapojit nositele so šperku. Kolekce čítá sedm šperkůObhájenoThe theme of my bachelor's thesis is "Jewel for ..." I chose the themes of play, movement and folding for my work. These topics are very close to me. The basis for my work was to create a system that would allow the movement of individual components. Next, creating individual segments and assembling them together. Every jewelery is very playful and movable. The material used for work is brass and steel wires. The collection of jewels is supposed to encourage them to play with them. The collection contains seven jewel
