  1. 1. Riparian vegetation ecology : an observational study into the effects of forest management on understory vegetation communities along boreal headwaters

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

    Författare :Ruben Jonathan Baan Hofman; [2023]
    Nyckelord :riparian forest; forest management; understory vegetation; headwater streams; community ecology;

    Sammanfattning : Riparian forests along headwater streams have long been recognized for their role as an interface between the terrestrial and aquatic ecosystem. The over- and understory vegetation performs essential ecological and biochemical functions, which are important for stream functions. LÄS MER

  3. 2. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lukas Rehn; [2021]
    Nyckelord :Boreal catchments; carbon cycling; carbon dioxide; DIC; headwater streams; Krycklan Catchment Study; trend analysis;

    Sammanfattning : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.

  4. 3. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Julia Iwan; [2021]
    Nyckelord :Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Sammanfattning : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. LÄS MER

  5. 4. Quantification of Terrestrial CO2 Sources to a Headwater Streamin a Boreal Forest Catchment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elin Hultin Eriksson; [2016]
    Nyckelord :Deep soil respiration; headwater streams; lateral CO2 export; CO2 storage; riparian zone; Krycklan; Djup jordrespiration; bäckar; lateral CO2-export; CO2-lagring; riparianzon; Krycklan;

    Sammanfattning : Carbon Dioxide (CO2) emissions from streams are a significant component of the global carbon cycle.Terrestrial export of CO2 through runoff is increasingly recognized as a major source of CO2 in boreal headwater streams. LÄS MER

  7. 5. How does nutrients and light affect algal growth in Swedish headwater streams? : A study using nutrient diffusing substrate and natural gradients of light

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

    Författare :Jannika Andersson; [2014]
    Nyckelord :: boreal streams; algal productivity; N limitation; nutrient diffusing substrate; incident light;

    Sammanfattning : Gaining knowledge about what factors determine benthic algal biomass and productivity is vital for understanding food webs in aquatic systems, especially in woodland streams with naturally low rates of primary productivity. The aim of this study was to investigate what factors determine algal growth in Swedish headwater streams. LÄS MER
