  1. 1. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE

  3. 2. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Esther Taiwo Afolabi; [2023]
    Keywords : chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Abstract : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. READ MORE

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Amanda Johansson; [2023]
    Keywords : ;

    Abstract : Scots Pine (P. sylvestris L.) has one of the largest distributions among trees in Eurasia. It is important both economically and ecologically, with a dominant role in forests ecosystems. READ MORE

  5. 4. Relations between tree and habitat characteristics and the epiphytic lichen flora on oak : a case study from Lövön, Bohuslän

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Julia Siegel; [2023]
    Keywords : Epiphytic lichens; Tree characteristics; Habitat characteristics; Oak; Biodiversity; Natural values; Light availability;

    Abstract : Oak-rich forests and wooded pastures harbor diverse and distinct epiphytic lichen flora with many rare and threatened species. As these habitats have been subject to a substantial decline and degradation over the past centuries, oak woodlands have progressively come into focus for preservation. READ MORE

  6. 5. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Elijah Ourth; [2023]
    Keywords : Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

    Abstract : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.
