  2. 1. Microbial Metagenomics : A Tale of the Dead and the Living

    Author : Katarzyna Zaremba-Niedźwiedzka; Siv G.E. Andersson; Jeroen Raes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single-cell genomics; single cell; fossil metagenome; freshwater metagenome; LD12;

    Abstract : It is a microbial world we live in: microbes outnumber other organisms by several orders of magnitude, and they have great importance for the environment. However, environmental microbes are notoriously difficult to grow in the laboratory, and using culture independent techniques is necessary to expand our view. READ MORE

  4. 2. Diversity of soil microbial communities: In the perspective of targeting functional genes

    Author : Lokeshwaran Manoharan; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

    Abstract : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. READ MORE

  5. 3. Soil microbial diversity in agriculture : Responses to land-use and extreme weather events

    Author : Katja Kozjek; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agriculture; drought; soil microbial communities; taxonomic diversity; functional diversity;

    Abstract : Land-use intensification of agricultural soils and increased occurrence and intensity of extreme weather events like drought periods are two of the main threats responsible for soil biodiversity declines. These changes in soil biodiversity can alter ecosystem functions performed especially by soil microbial communities that could further contribute to those threats. READ MORE

  6. 4. Expanding the Chlamydiae tree : Insights into genome diversity and evolution

    Author : Jennah E. Dharamshi; Thijs J. G. Ettema; Alexander Probst; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PVC superphylum; Chlamydiae; chlamydia; intracellular; symbiosis; endosymbiont; pathogen; marine sediment; sponge microbiome; metagenomics; uncultured microbial diversity; phylogenomics; microbial evolution; eukaryote evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Chlamydiae is a phylum of obligate intracellular bacteria. They have a conserved lifecycle and infect eukaryotic hosts, ranging from animals to amoeba. Chlamydiae includes pathogens, and is well-studied from a medical perspective. READ MORE

  7. 5. Significance and Diversity of Lake Bacteriophages

    Author : David Lymer; Eva Lindström; Lars Tranvik; Ruth-Anne Sandaa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; viral ecology; lake; bacteriophage; diversity; phosphorus; Freshwater ecology; Limnisk ekologi;

    Abstract : Viruses has a relatively recently been discovered in high abundances in aquatic systems. Their possible importance has therefore been largely overlooked. READ MORE
