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

    University essay from Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakulteten

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Ecology

    Author : Markus Juuso; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 19. Clear-cut and substrate characteristics important for the occurrence of the beetle Upis ceramboides

    University essay from SLU/Dept. of Ecology

    Author : Ronny Naalisvaara; [2013]
    Keywords : Upis ceramboides; dead wood; clear-cut; prescribed burning;

    Abstract : Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. READ MORE

  6. 20. Qualities and supply of suitable dead wood for Ceruchus chrysomelinus and its dispersal pattern in a translocated population

    University essay from SLU/Dept. of Ecology

    Author : Malin Karlsson; [2012]
    Keywords : Ceruchus chrysomelinus; saproxylic beetle; translocation; dead wood; dead wood qualities; suitable substrate; species conservation; conservation biology;

    Abstract : The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. READ MORE
