1. Network Based Tools and Indicators for Landscape Ecological Assessments, Planning, and Design
Sammanfattning : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.

2. Exploring synergies – management of multifunctional agricultural landscapes
Sammanfattning : AbstractHuman ingenuity and activities have resulted in erosion of ecosystems and their capacity to support the sustainable production of goods and functions that we depend on. Biodiversity i.e. LÄS MER
3. Black mustard and the butterfly effect : metabolomics of plant-insect interactions under multiple stress conditions
Sammanfattning : One main goal of ecological research is to understand nature´s complexity, in order to predict the potential impact of environmental perturbations. In this thesis, I investigate the ecological interactions between some of the most ancient organisms living on our planet: plants and insects. LÄS MER
4. Ocean chemistry and the evolution of multicellularity
Sammanfattning : Oxygen has been assumed to be a vital trigger for the evolution of multicellular life forms on Earth, partly based on its power to promote substantial energy flux in cell respiration and partly as biosynthesis of compounds like collagen require oxygen. However, the co-evolution of large life and the Earth’s chemical environment is not well understood at present, and there is particular disagreement in the field about whether the Cambrian explosion of animal life forms was a chemical or biological event.
