1. Skogen som livsmiljö : En rättsvetenskaplig studie om skyddet för biologisk mångfald
Sammanfattning : Globally, species are being eradicated at an accelerated rate, up to 1000 times faster than the rate of natural species loss. This is primarily due to the reduction and degradation of species habitats. As biodiversity decreases, ecosystems risk losing significant ecological processes and functions, such as natural water purification. LÄS MER
2. Towards a Minor Urbanism : Thinking Community without Unity in Recent Makings of Public Space
Sammanfattning : HOW CAN WE PLAN AND DESIGN FOR community in diverse urban situations? In response to segregation and social fragmentation, public space is increasingly being conceived of as a vehicle for fostering openness towards differences, both in planning practice and theory. Drawing on two recent public space projects – Superkilen in Copenhagen, Denmark, and Jubileumsparken in Gothenburg, Sweden – this thesis explores what this hopeful idea may mean in terms of the actual making of public space.

3. Bonden och landskapet : Ägares och brukares relationer till markerna och förutsättningarna för en uthållig markanvändning
Sammanfattning : Farmers and Landscape. Owners and farmers relations to their land, and the prospects for sustainable land use. In a transition towards sustainability, rural land use is of certain interest, owing to the environmental impact of modern farming and forestry, and also to its potential role in a recycling society.

4. Metapopulation ecology of Osmoderma eremita - dispersal, habitat quality and habitat history
Sammanfattning : This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of Osmoderma eremita, a threatened beetle living in hollow trees. I concentrate on the effect of dispersal, habitat quality and habitat history for the presence, population size and future survival of this species. LÄS MER
5. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management
Sammanfattning : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.
