1. Biodiversity and Species Extinctions in Model Food Webs
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.

2. Stochasticity in Biophysical Systems: Searching, Aging, and Spreading
Sammanfattning : The role of stochasticity throughout many biophysical systems is of great importance. From evolution to foraging, from the spreading of viruses to cell fate, all hinge in one way or another on inherent stochasticity. LÄS MER
3. Food Webs, Models and Species Extinctions in a Stochastic Environment
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
4. Population and Community Dynamics in Variable Environments
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
5. Establishment, Growth and Population Dynamics in two Mosses of Old-growth Forests
Sammanfattning : Biodiversity in forests depends on long canopy continuity and existence of different elements which function as substrates for varying organisms. Bryophytes often occupy specific substrates with a patchy distribution. LÄS MER
