  1. 31. Who comes first? Implications of the plant-microbiome-soil continuum feedback on plant performance

    Författare :David Castro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plants are sessile organisms that rely on their ability to explore the soil to access the nutrients and water they need to survive. Plants have co-evolved with certain groups of bacteria and fungi that provide nutrients and water and enhance tolerance to abiotic and biotic stressors in exchange for Carbon (C). LÄS MER

  3. 32. Northern peatland carbon biogeochemistry : the influence of vascular plants and edaphic factors on carbon dioxide and methane exchange

    Författare :Mats Öquist; Bo Svensson; Joseph B. Yavitt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biogeokemi; Biologi; Autekologi; Klimatologi; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The interest in carbon dynamics and the interactions between ecosystems and the atmosphere has increased during the last decade due to the postulated threat of anthropgenically induced global and climate change. Northern peatlands, with their large stores of organic carbon and long-term net accumulation of atmospheric carbon dioxide are key ecosystems in these interactions. LÄS MER

  4. 33. Genome Evolution and Niche Differentiation of Bacterial Endosymbionts

    Författare :Kirsten Maren Ellegaard; Siv Andersson; Andrés Moya; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; niche; habitat; endosymbiont; gut microbiome; honey bee; Wolbachia; comparative; genomics;

    Sammanfattning : Most animals contain chronic microbial infections that inflict no harm on their hosts. Recently, the gut microflora of humans and other animals have been characterized. However, little is known about the forces that shape the diversity of these bacterial communities. LÄS MER

  5. 34. Communities of microalgae and bacteria in photobioreactors treating municipal wastewater

    Författare :Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Catherine Legrand; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Everyone who uses water produces wastewater. This inevitability creates several problems that increase with the growth of the population and industry. LÄS MER

  7. 35. Nitrogen in soil water of coniferous forests : effects of anthropogenic disturbances

    Författare :Martin Rappe George; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In boreal and temperate forests, long-term elevated nitrogen (N) load may eventually saturate forest ecosystems with N, i.e. total N ecosystem input exceed ecosystem sinks for N, and N losses via soil water transport may then increase and negatively impact environmental quality.
