1. Nutrient imbalance in Norway spruce
Abstract : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. READ MORE

2. 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.

3. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management
Abstract : Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. READ MORE

4. Fisheries Management under Individual Transferable Quota : Outcomes for Ecology and Equity
Abstract : The management of marine resources pose a difficult commons problem as monitoring behavior is difficult and benefit flows from the resources are uncertain. Implementing individual transferable quota (ITQ) is a management regime in which quasi-property rights are assigned for an often mobile and uncertain environmental resource, fish or marine invertebrates.

5. Effects of forest fire and the ecology of fire-adapted insects
Abstract : Fire is widely recognised for its major impact on boreal forest ecosystems. The altereddisturbance regime due to effective fire suppression and extensive forestry may be a majorthreat to biodiversity.If logging preceded burning, the pyrophilous (Gr. fire-loving) beetle Sericoda quadripunctata failed to reproduce.
