  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. Controls over stream temperature in a northern boreal landscape

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

    Author : Oskar Damström; [2023]
    Keywords : Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Abstract : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. READ MORE

  4. 3. Mercury in a Swedish landscape over 30 years : a thesis on mercury concentrations in different water-cathments in Krycklan and Degerö stormyr

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

    Author : Ted Pettersson; Isak Haglund; [2023]
    Keywords : Atmospheric deposition; concentrations; dissolved organic carbon; mercury; methylmercury; peatlands; water-catchments;

    Abstract : The purpose of this thesis is to examine trends in concentrations of total mercury (TotHg) and methylmer¬cury (MeHg) in water streams around Vindeln, Sweden, located northwest of Umeå. The relation¬ship between dissolved organic carbon (DOC) and TotHg were also examined in this thesis. READ MORE

  5. 4. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sandra Edström; [2022]
    Keywords : groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

    Abstract : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

  6. 5. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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.
