1. Small remnant habitats : Important structures in fragmented landscapes
Abstract : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. READ MORE

2. A window into forest landscapes : Studying the relationship between forests, ownership, ecosystem services, and biodiversity in landscapes
Abstract : Production forests are faced with the challenge of adapting to environmental change and simultaneously helping mitigate it and host rich biodiversity. This leads to new conflicts and trade-offs for forest management. Many management options have been proposed to achieve these goals while minimizing the loss of timber production. READ MORE

3. Bees and wasps (Aculeata) in young boreal forests
Abstract : In Sweden, forest stands younger than 15 years constitute more than 10% of the total forest area. The aims of the research described in this thesis were to investigate how bees and wasps (Aculeata) use young boreal forests as nesting and feeding grounds.

Abstract : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. READ MORE
