  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

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

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 2. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    University essay from SLU/Dept. of Soil and Environment

    Author : Bella Strid; [2024]
    Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

  4. 3. Stadsträd – i nöd och lust : skillnader i reglerande och stödjande ekosystemtjänster mellan löv- och barrträd i stadsmiljö

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Jennifer Engelbrekt Tchang; Sara Karlsson; [2023]
    Keywords : ekosystemtjänst; lövträd; barrträd; stadsträd; luftrening; dagvattenhantering; vindskydd; temperaturreglering; kolupptagning; kolinlagring; biologisk mångfald;

    Abstract : Träd har en viktig roll i att klimatanpassa städer genom att leverera ekosystemtjänster. I nordiska städer planteras mest lövträd eftersom det historiskt funnits ett kulturellt motstånd mot barrträd. READ MORE

  5. 4. Föryngring med hägn : effekten av viltbete på självföryngrad ädellövskog i tre skånska naturreservat

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

    Author : Håkan Ramberg; Kaj Sjöqvist; [2023]
    Keywords : Bokskog; naturlig föryngring; betesbegärlighet; viltbete; strukturförändring;

    Abstract : Ädellövskogens artsammansättning styrs av flera naturliga processer, en av dessa processer är viltbete. Bete kan leda till att trädslagsfördelningen förändras och att föryngring blir problematiskt, speciellt i områden med stora viltstammar och för de mer betesbegärliga trädarterna. READ MORE

  6. 5. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests

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

    Author : Ella Amnéus; Sebastian Hjelström; [2023]
    Keywords : Saproxylic Beetles; Ecological Restoration; Deadwood; Biodiversity; Boreal Forest; Fire Ecology; Land-sparing; Land-sharing; Conservation Management;

    Abstract : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.
