6. Microbial Ecology of Granular Sludge
Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER
7. Transition to a low-carbon electricity system — investment decisions under heterogeneity, uncertainty and financial feedback
Sammanfattning : A transition to a low-carbon electricity system will require a substantial increase in the investment rate in low-carbon technologies. This calls for a better understanding of investment decisions and their impact on the pace of the transition. LÄS MER
8. Grassland restoration : Connectivity, plant community change and cows
Sammanfattning : The ecological significance of semi-natural grasslands is high because these habitats provide a home for a diverse flora and fauna and support a range of associated ecosystem services. Due to large-scale land-use changes the extent of grassland habitat has declined. LÄS MER
9. Inference and management of populations in variable environments
Sammanfattning : Population dynamics in space and time are manifested as changes in the distribution and abundance of organisms. To couple such patterns to the underlying processes is a central question in ecology and also key to successful management. LÄS MER
10. Empirical and theoretical studies of population trends and extinction risks
Sammanfattning : Empirical and theoretical approaches are needed to solve the current problem of increased extinction risk for many species. Thus, this thesis focuses on: (1) ways to estimate population trends for a large number of species, and (2) a predictive framework for identifying vulnerable populations from species traits or life history traits to allow for more proactive conservation actions.
