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
2. 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
Sammanfattning : Many of the earth’s ecosystems are experiencing large species losses due to human impacts such as habitat destruction and fragmentation, climate change, species invasions, pollution, and overfishing. Due to the complex interactions between species in food webs the extinction of one species could lead to a cascade of further extinctions and hence cause dramatic changes in species composition and ecosystem processes. LÄS MER
Sammanfattning : In light of the current global mass extinction of species, ecologists are facing great challenges. In order to reverse the path towards additional extinctions early warning systems to guide management actions need to be developed. LÄS MER
Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER
