  1. 1. Acoustic Doppler Current Profiling for streamflow measurements in subarctic climate

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Linus Nyström; [2022]
    Keywords : ;

    Abstract : The ADCP (Acoustic Doppler Current Profiling) technology has been widely available and acknowledged as an instrument used for different types of flow measurement since 1990s, from small scale river measurements to larger ocean current mappings. This study was conducted by the author in cooperation with SWECO with the focus on smaller scale measurements especially on small natural watercourses in a sub-arctic climate with the purpose to examine if the ADCP technology can be used as a complement to the more classic methods for this type of flow measurements Current meter and Conductivity flow measurements.

  2. 2. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

    University essay from SLU/Dept. of Ecology

    Author : Khadija Aziz; [2022]
    Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

    Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification.

  3. 3. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Lindqvist; [2022]
    Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE

  4. 4. The importance of forest forage resources and a landscape perspective, managing bumblebees (Bombus) in Swedish forest-farmland

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Linda Dimrå; [2022]
    Keywords : Bombus; Forest; Vaccinium Myrtillus; Landcover change;

    Abstract : The Swedish forest has been transformed during the last hundred years, from semi-open forest of multiple tree species to dense production forest of mainly spruce and pine. This has led to alterations of species composition in the forest floor, reducing coverage of dwarf shrubs like Vaccinium myrtillus (European blueberry). READ MORE

  5. 5. How do forest characteristics relate to brown bear (Ursus arctos) density? : focusing on basal area, age, height, and field layer

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Jeanette Jonsson; [2022]
    Keywords : brown bear; ursus arctos; linear mixed model; forest characteristics; bear density;

    Abstract : Brown bear (Ursus arctos) is one of our most common large carnivores. The historic population in Sweden has been reduced due to conflicts with humans. The diet of the brown bear varies with the season and location. READ MORE
