  4. 17. 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

  6. 19. Microorganisms in the atmosphere

    Author : Camilla Fahlgren; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology;

    Abstract : Bacteria are present everywhere around us; in water, soil, food, on our skin, and in the air we breathe, mainly as parts of aerosols (i.e. minute air-suspended particles). Aerosols are mainly composed of sea salt, dust, sulphates and soot but some also contain bacteria, virus, pollen, plant debris and organic matter (i. READ MORE

  7. 20. Vanadium in soils : chemistry and ecotoxicity

    Author : Maja Larsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Vanadium is a redox-sensitive metal that is released to soils by weathering and anthropogenic emissions. Swedish metallurgical slags are naturally high in vanadium and used as soil amendments and in road materials. However, understanding of vanadium chemistry and bioavailability in soils is limited.
