  1. 1. Saproxylic beetles in Populus tremula fauna depots - how do you construct the best depot?

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Simon Selberg; [2019]
    Nyckelord :aspen; populus; tremula; saproxylic; beetle; fauna; depot; species; richness; abundance; diversity; cwd; course; woody; debris; forest; asp; populus; tremula; vedlevande; skalbagge; fauna; depå; art; mångfald; diversitet; död; ved; cwd; skog;

    Sammanfattning : The biodiversity of saproxylic organisms and in the case of this study, saproxylic beetles, is dependent on the amount and quality of course woody debris (CWD) in the environment. Over the past decades the quantity of CWD in Swedish forests has increased, yet the quality has decreased, forests are managed and exploited, and old-growth forests are rarer. LÄS MER

  2. 2. Community structure of polyporous fungi after wildfire in boreal forest

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

    Författare :Isak Vahlström; [2019]
    Nyckelord :biodiversity; community composition; natural disturbance; forest fire; polyporous fungi; ; wood-decaying fungi;

    Sammanfattning : Wildfire is a natural disturbance that creates large amounts dead wood and contribute to a landscape of different successional stages, important for biodiversity. The number of wildfires have declined in boreal Fennoscandia due to effective fire suppression. LÄS MER

  3. 3. Fjärranalys av kantzoner och död ved i Natura 2000- vattendrag : Hur har det förändrats över tid?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Valdemar Samuelsson; [2019]
    Nyckelord :Riparian zone; LWD large woody debris ; remote sensing; Natura 2000; Kantzon; död ved; fjärranalys; Natura 2000;

    Sammanfattning : The forestry is the main use of forests in Sweden which results in a number of positive aspects but also a number of negative effects on our nature. Aquatic ecosystems are specifically exposed to land use by the forest industry. LÄS MER

  4. 4. Above- and belowground carbon stocks and effects of enrichment planting in a tropical secondary lowland dipterocarp rainforest

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

    Författare :Joel Jensen; [2019]
    Nyckelord :Restoration; tree diversity; biodiversity; soil edaphic factors; functional species groups; liberation; forest degradation;

    Sammanfattning : The intact tropical rainforests are rapidly being degraded and subsequently converted to other land uses, with associated greenhouse gas emissions and loss of biodiversity. It is imperative that the effects of such conversions and large-scale restoration efforts on forest structure and ecosystem services are understood to effectively be able to counteract the negative consequences of deforestation and forest degradation.

  5. 5. 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
