  1. 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 Studies

    Author : KajsaLisa Olsson; [2024]
    Keywords : Tallimpediment; biologisk mångfald; vedlevande skalbaggar; naturvårdsbränning; Pinus sylvestris;

    Abstract : 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

  3. 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 Management

    Author : Emma Mattsson; Lena Ostermann; [2023]
    Keywords : Vitryggig hackspett; vedlevande skalbaggar; paraplyart; rödlista; biologisk mångfald; död ved; restaurering;

    Abstract : 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

  4. 3. 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 Ecology

    Author : Tore Dahlberg; [2023]
    Keywords : polypores; dead wood volume; Amyloporia sinuosa; A. xantha; Neoantrodia serialis; Nemapogon fungivorellus; Agnathosia sandoeensis;

    Abstract : 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

  5. 4. 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 Management

    Author : Ella Amnéus; Sebastian Hjelström; [2023]
    Keywords : Saproxylic Beetles; Ecological Restoration; Deadwood; Biodiversity; Boreal Forest; Fire Ecology; Land-sparing; Land-sharing; Conservation Management;

    Abstract : 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.

  6. 5. 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 Studies

    Author : Tyr Nilsson; [2022]
    Keywords : Slow-grown trees; growth rate; ring width; pinus sylvestris; picea abies; low-productive forests; mires; rocky outcrops; swedish NFI;

    Abstract : 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
