1. 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
2. STUDY OF BACTERIAL COMMUNITIES : – A WASTEWATER TREATMENT PERSPECTIVE
Sammanfattning : In this thesis, the application of molecular microbiology methods to understand wastewater treatment bio-reactions is described. Two different wastewater treatment systems were chosen for the experimental work. LÄS MER
3. Assembly Mechanisms in Aquatic Bacterial Communities : The Role of Disturbances, Dispersal and History
Sammanfattning : Environmental conditions, biotic interactions, dispersal and history have been suggested to be important processes influencing the spatial distribution of organisms and thus to affect community assembly. Understanding how these processes influence community assembly is important, particularly because community diversity and composition are suggested to be relevant for ecosystem functioning. LÄS MER

5. Factors Affecting Rates of Change in Soil Bacterial Communities
Sammanfattning : The soil bacterial community is under the constant influence of its environment. Changing any of the factors affecting the bacterial community will induce a selection pressure which, with time, will change the community. In this work the effect of changing the temperature or pH on the soil bacterial community was studied. LÄS MER
