1. Mängden död ved i värdekärnor i Söderåsens nationalpark
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

2. Vedlevande skalbaggar 10–20 år efter brand i tallskog : en jämförelse mellan hällmark och produktiv mark
Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. LÄS MER
3. Insects in conifer logs : their association to the polypore fungi Amyloporia sinuosa, A. xantha and Neoantrodia serialis and impact of aggregations of wood
Master-uppsats, SLU/Dept. of EcologySammanfattning : A large number of insects are associated with polypores. They can be monophagous, polyphagous and use several fungal hosts, or be parasites on the insects utilize the fungus. The insect assemblage for some polypores is well investigated but there is still a lack of knowledge for many species. LÄS MER
4. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER
5. Count on dead wood : a comparison of nature conservation value assessment methods concerning dead wood
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Dead wood is acknowledged world-wide for its interconnection to biodiversity and sustainable forest management. In Sweden, today’s retention forestry requires measures to protect and create dead wood, which raise the need of inventory methods for estimating dead wood quantity and quality. LÄS MER
