1. Vedlevande skalbaggar 10–20 år efter brand i tallskog : en jämförelse mellan hällmark och produktiv mark
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : 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. READ MORE

2. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Den vitryggiga hackspetten har sedan 1950-talet blivit en sällsynt art i det svenska landskapet. Nedgången beror främst på det moderna skogsbruket där barrskog till stor del har ersatt blandbestånd och gammal lövskog. READ MORE

3. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

4. Minskande senvuxenhet på produktiv skogsmark i Norrland : implikationer för vedlevande organismer och betydelsen av myr- och bergimpediment
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Senvuxen ved är ett viktigt substrat för vissa vedlevande organismer på grund av en långsam nedbrytning och låg konkurrens. Tillväxtförhöjande åtgärder inom skogsbruk, liksom ökande temperaturer, kan ha orsakat en minskning av senvuxen ved under den senare halvan av 1900-talet. READ MORE

5. The wood-inhabiting fungal community on standing dead birches : a comparison of ring-barked and naturally dead trees
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Dead wood is an important part of forest ecosystems, especially since so many organisms depend on it for nutrients or as substrate for breeding or foraging. Since forestry intensified in northern Europe during the mid 1900s, the amount of dead wood in Fennoscandian forests has drastically decreased. READ MORE
