6. A song of ice and mud : Interactions of microbes with roots, fauna and carbon in warming permafrost-affected soils
Sammanfattning : Permafrost-affected soils store a large quantity of soil organic matter (SOM) – ca. half of worldwide soil carbon – and currently undergo rapid and severe warming due to climate change. LÄS MER
7. Pelagic microorganisms in the northern Baltic Sea : Ecology, diversity and food web dynamics
Sammanfattning : Heterotrophic microorganisms are important for the flow of carbon and nutrients in the sea. Bacteria, nanoflagellates and ciliates are relevant components of the pelagic food web. In order to be able to predict the outcome of e.g. LÄS MER
8. Consequences of consumer-resource stoichiometric imbalance in planktonic food webs
Sammanfattning : Resource imbalance between consumers and their resources can come from inadequate resource quantity or quality. The ecological stoichiometry theory focuses on understanding the consequences of imbalance in elemental composition. In this thesis, I have used both resource quality (e.g. LÄS MER
9. Microbial communities : descriptors of environmental change in marine ecosystems
Sammanfattning : In northern marginal seas, like the northern Baltic Sea, climate change will lead to many alterations, for example increased inflows of nutrients and dissolved organic matter (DOM). Nutrients and DOM are fundamental drivers shaping marine microbial communities, including both bacterial and phytoplankton populations. LÄS MER
10. Drivers of increasing iron concentrations in freshwaters
Sammanfattning : Iron (Fe) concentrations are increasing in freshwaters (lakes and streams) in Sweden, as well as in other regions in northern Europe. Together with increasing concentrations of organic matter, Fe is contributing to the ongoing browning of freshwaters, which may have serious ecological consequences and implications for ecosystem services.
