  1. 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 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

  3. 2. Birch for Future: Yay or Nay?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Swastika Chakravorty; [2022]
    Keywords : Betula pendula Roth; Biodiversity; Growth; Simulation; Species Mixture;

    Abstract : Birch (Betula pendula Roth in this study) is a widespread broadleaf species in the Swedish forests. Different birds, saproxylic insects, understorey vascular plants and mycorrhizal fungi are dependent on birch and birch deadwood. The mixture of birch and Norway spruce (Picea abies (L. READ MORE

  4. 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)

    Author : Matilda Apelqvist; [2022]
    Keywords : Detection dog; indicate synthetic pheromone; coleoptera; conservation biology; endangered species;

    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

  5. 4. 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 Biology

    Author : Patrik Jonas Krister Celander; [2020]
    Keywords : Longhorn beetle; Cerambycidae; Lesser spotted woodpecker; Dryobates minor; Dendrocopos minor; Pheromone; Conservation;

    Abstract : 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

  6. 5. 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
