1. Network Based Tools and Indicators for Landscape Ecological Assessments, Planning, and Design
Abstract : 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. Biodiversity in fragmented boreal forests : assessing the past, the present and the future
Abstract : The aims of this thesis are to (1) analyze the predictability (indicators) of plant and fungal species diversity in old-growth forests, and (2) assess the history and biodiversity of woodland key habitats (WKHs) and their potential to maintain species diversity in fragmented boreal forest landscapes. Predictability was explored in Granlandet nature reserve, an unexploited landscape composed of discrete old-growth Picea forest patches of varying size isolated by wetland, reflecting conditions of insular biota at stochastic equilibrium.

3. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests
Abstract : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. READ MORE

4. Life History of the Common Gull (Larus canus) : A Long-Term Individual-Based Study
Abstract : An individual’s life history is a sequence of events which eventually determine its contribution to the next generation, or fitness. These events are affected by environmental factors, genetic make-up and decisions made by an individual and its breeding partner. READ MORE

5. Exploring connections in social-ecological systems : The links between biodiversity, ecosystem services, and human well-being in South Africa
Abstract : A key challenge of the Anthropocene is to advance human development without undermining critical ecosystem services. Central to this challenge is a better understanding of the interactions and feedbacks between biodiversity, ecosystem services and human well-being, which interact in dynamic and complex social-ecological systems.
