26. Effects of size-dependent predation and competition on population and community dynamics
Sammanfattning : Most animals grow substantially during their lifetime and change in competitive ability, predatory capacity and their susceptibility to predation as they grow. This thesis addresses the implications of this on regulation and dynamics within populations as well as between population interactions. LÄS MER
27. Application of aerobic granular sludge for municipal wastewater treatment - Process performance and microbial community dynamics under fluctuating conditions
Sammanfattning : Pressures of growing cities, competition for use of urban areas and higher influent loads, are pushing for innovative technologies for wastewater treatment with low demands for land footprint and costs. Furthermore, wastewater treatment is needed to move towards a circular economy by harvest of valuable resources such as nutrients and energy. LÄS MER
28. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden
Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER
29. Terahertz spin dynamics in metallic thin film ferromagnets
Sammanfattning : The past two decades have witnessed an increasing interest in understanding and controlling materials at the pico- and femtosecond time scales, the so-called ultrafast regime. Among the broad field of condensed matter physics, magnetism and magnetic materials have attracted much interest both from a fundamental and an applied perspective. LÄS MER
30. Microbial community dynamics in the phyllosphere of leafy vegetables
Sammanfattning : Microbes interact with the phyllosphere creating a plant microbiota holobiont. From a food safety aspect the phyllosphere is especially important in leafy vegetables which are generally consumed raw. Plant-microbe interactions are complex, but well-known ecological concepts can be applied to explain the dynamics. LÄS MER
