  1. 26. Explaining population size of the saproxylic beetle Prionus coriarius as a function of available dead wood resources

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Isak Sarac; [2016]
    Nyckelord :pheromone; coleoptera; cerambycidae; dispersal; threshold; conservation;

    Sammanfattning : Dead wood is an important substrate for many forest bound species including the large group of dead wood associated (saproxylic) beetles. Saproxylic beetles have species specific substrate requirements, that may vary according to factor such as tree species, object type, trunk diameter and decomposition stage. LÄS MER

  3. 27. Artificial gap creation and the saproxylic beetle community : the effect of substrate properties on abundance and species richness

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Nils Bodin; [2016]
    Nyckelord :boreal forest; nature conservation; saproxylic beetle; artificial gap creation; restoration measure; coarse woody debris;

    Sammanfattning : Coarse dead wood (CWD) and gaps are structures that have become sparse in Swedish forests as a result of forestry. This is believed to be one factor contributing to diminishing biodiversity. Because of political undertakings to preserve biodiversity, Swedish agencies and forestry companies now aim to restore these and other structures. LÄS MER

  4. 28. Boxing for biodiversity: a long-term follow up of an artificial dead wood environment

    Master-uppsats, Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakulteten

    Författare :Staffan Carlsson; [2015]
    Nyckelord :Artificial habitats; saproxylic beetles; wood mould boxes; hollow trees; succession;

    Sammanfattning : Today many saproxylic species are threatened because of habitat decline in Europe. Hollow trees represent a great part of the habitats that saproxylic species use. Since hollows takes a long time to develop, management actions are needed to prevent the extinction of saproxylic species. LÄS MER

  5. 29. The effect of stump extraction on the diversity of saproxylic insects in the roots of Norway spruce (Picea abies) stumps

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Markus Juuso; [2015]
    Nyckelord :tree stump extraction; Norway spruce; Picea abies; roots; Sweden; saproxylic insects; biodiversity; ecological trap; saproxylic beetles; effect of stump extraction; stump extraction piles; biofuel; stumps;

    Sammanfattning : This study examined the effect of tree stump extraction on the diversity of saproxylic insects in Norway spruce Picea abies roots. I tested if the density of saproxylic beetles was the same in the interior layer of the stump storage piles as in the exterior layer. LÄS MER

  7. 30. Restaureringsåtgärders korttidseffekter på biodiversiteten bland vedlevande skalbaggar (Coleoptera) på granstammar

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Amanda Trulsson; [2015]
    Nyckelord :restaurering; bränning; luckhuggning; död ved; biologisk mångfald;

    Sammanfattning : Skogsbruket har haft en stor negativ påverkan på skogens biodiversitet. Speciellt gäller detta saproxyliska organismer och arter starkt gynnade av eller beroende av skogsbrand. LÄS MER
