    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Susanne Debourg; [2018]
    Nyckelord :Clear-cutting; clear-cut; forestry; biodiversity; ecosystem services; forestry legislation; Trakthyggesbruk; kalhygge; skogsbruk; biologisk mångfald; ekosystemtjänster; skogsvårdslagstiftning; Biology and Life Sciences; Earth and Environmental Sciences;

    Sammanfattning : 80% of all forest in Sweden is considered to be in active use and since the mid 20th century, clear-cutting is the dominating forestry management method. The implication of clear-cutting is that large areas (up to 200 hectare) are being harvested at once and leaving bare ground as a result. LÄS MER

  3. 32. Studie av rottickans S-form i ett röjningsbestånd av gran

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Andreas Östlund; [2017]
    Nyckelord :rotstop; kärnvedsandel; stubbdiameter;

    Sammanfattning : The aim of this study was to examine if heartwood properties and stump diameter affected the establishment of Heterobasidion parviporum in a Norway spruce stand at the stage of pre-commercial thinning. In addition, the effects of Rotstop® application on the stumps were investigated. LÄS MER

  4. 33. Histological Investigation of the testicular nerves at the castration site in geldings

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Emma Angelina Bengtsdotter; [2017]
    Nyckelord :castration; testicle; nerve; neuroma; pain; gelding;

    Sammanfattning : Castration is one of the most common surgical procedures in equine medicine and associated with a number of postoperative complications such as swelling, infection, haemorrhage, peritonitis, funiculitis, omental herniation and eventration. But what happens with the testicular nerves after crushing and severing during the procedure? An injured nerve can respond with degeneration and/or regeneration. LÄS MER

  5. 34. 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

  7. 35. Evaluation of Phlebiopsis gigantea and Pseudomonas spp. for biocontrol of Heterobasidion spp. in Norway spruce

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Zelma Gžibovska; [2016]
    Nyckelord :Heterobasidion spp.; Phlebiopsis gigantea; Pseudomonas spp; Rotstop; biological control;

    Sammanfattning : Root rot caused by the fungal pathogen Heterobasidion spp. is one of the most spread and devastating conifer diseases in the Northern Hemisphere. There is increasing interest from the forestry sector in new biological agents and means of control for Heterobasidion spp., as root rot becomes an economically more important issue. LÄS MER
