1. Extinctions and Ecosystem Stability
Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER
2. Stability and complexity of ecosystems - Global interaction constraints, landscape and extinctions
Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER
3. The emergence of innovation ecosystems: Exploring the role of the keystone firm
Sammanfattning : During periods of technological change, firms seek new collaborations and sometimes even reach out to competitors in order to obtain new resources and competences. Understanding the collaborations surrounding new technologies has implications for firms pursuing opportunities with new technologies. LÄS MER
4. 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.

5. Ecological systems in space: From islands to contiguous landscapes
Sammanfattning : Dispersal and interaction networks underlie many ecological systems, often dictating spatio-temporal dynamics as well as emergent patterns. Dispersal has implications for establishment for distinct subpopulations of individual species as well as for the emergence of universal spatial patterns and varied community level structures. LÄS MER
