  2. 1. Consequences of Environmental Variation for Fish and Their Skin Associated Microbial Communities

    Author : Hanna Berggren; Anders Forsman; Per Larsson; Mark Dopson; Jarone Pinhassi; Richard Svanbäck; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi;

    Abstract : Environmental conditions that vary in space and time influence the distribution, abundance, diversity and evolution of individuals, populations, species and communities. This thesis explores how environmental variation affects diversity at different levels of biological organization, and across a wide range of spatiotemporal scales, by studying fish and their associated microbiomes.

  4. 2. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Author : Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. READ MORE

  5. 3. Function and Adaptation of Acidophiles in Natural and Applied Communities

    Author : Stephan Christel; Mark Dopson; Michael Schlömann; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acidophiles; Biomining; Psychrophiles; Adaptation; Acid Sulfate Soil; Redox Control; Ecology; Ekologi;

    Abstract : Acidophiles are organisms that have evolved to grow optimally at high concentrations of protons. Members of this group are found in all three domains of life, although most of them belong to the Archaea and Bacteria. READ MORE

  6. 4. Genomics, physiology and applications of cold tolerant acidophiles

    Author : Maria Liljeqvist; Mark Dopson; Ricardo Amilis; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Psychrotolerant acidophiles have gained increasing interest because of their importance in biomining operations in environments where the temperature falls well below 10°C during large parts of the year.Acidithiobacillus ferrivorans is the only characterized acidophile with the ability to live a psychrotrophic lifestyle and is able to oxidize ferrous iron and inorganic sulfur compounds at low temperature.

  7. 5. Growth and survival of Acidithiobacilli in Acidic, metal rich environments

    Author : Stefanie Mangold; Mark Dopson; Axel Schippers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Acidithiobacilli are acidophilic microorganisms that play important roles in many natural processes such as acidification of the environment, influencing metal mobility, and impacting on global sulfur and iron cycles. Due to their distinct metabolic properties they can be applied in the industrial extraction of valuable metals. READ MORE
