1. 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
2. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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. LÄS MER
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
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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. Training dogs to indicate synthetic pheromones from Plagionotus detritus, Coleoptera, Cerambycidae to detect living beetles
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Using dogs to detect insects’ emitted volatiles is a non-invasive procedure, and a trained detection dog is potentially a fast and accurate method to search for saproxylic insects. The longhorn beetle Plagionotus detritus is categorized as Endangered in the Swedish Red List of Threatened Species. LÄS MER
5. Vedlevande skalbaggar och andra naturvärden i brukad bokskog - En fallstudie av Tingvallaravinen i Skåne
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : Nature is in many ways crucial for human survival. However, due to human activity and exploitation, unique species and habitats are at risk of extinction. The forest is one habitat that has been deeply afflicted. A massive loss of forests worldwide due to intense forestry has led to a defeat of biodiversity. LÄS MER
