1. Insects in conifer logs : their association to the polypore fungi Amyloporia sinuosa, A. xantha and Neoantrodia serialis and impact of aggregations of wood
University essay from SLU/Dept. of EcologyAbstract : 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. READ MORE

2. 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.

3. Training dogs to indicate synthetic pheromones from Plagionotus detritus, Coleoptera, Cerambycidae to detect living beetles
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : 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. READ MORE

4. How do saproxylic beetles differ in spruce (Picea abies) forests of different age? : A comparison between nature reserves and production forests, in county of Östergötland.
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : Today, old growth forests are continuously decreasing, due to deforestation, threatening species to extinction. Species dependent on dead wood, different stages of decaying wood, large trees, and forest cover continuity have a particularly high risk of extinction, such as saproxylic beetle species. READ MORE

5. Longhorn beetles in lesser spotted woodpecker habitat : a pheromone-based inventory of longhorn beetles in southern Sweden
University essay from SLU/Dept. of Plant Protection BiologyAbstract : The understanding of species’ ecology and their trophic interactions, are crucial in the work of conservation. A population decline in a predatory species may be a result of a decline in their food source, a trophic level down. READ MORE
