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

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

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

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

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