  1. 1. 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

  3. 2. 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. 3. Spatial resolution of methane production and ebullition in Lake Alsta

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Evelina Hiltunen; [2021]
    Keywords : methane; ebullition; TN;

    Abstract : Freshwater ecosystems cover about 4 % of the Earth’s surface. Yet they are important components in the global C cycle, as they in addition to their within-lake primary production, receive and process organic matter loads originating from terrestrial environments. The boreal forest biome has the highest density of lakes globally. READ MORE

  5. 4. Patterns and factors affecting brownification in a boreal river

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emil Winqvist; [2021]
    Keywords : Bolmen; brownification; precipitation; discharge; sulfur deposition; land use; trend analysis; Technology and Engineering;

    Abstract : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. READ MORE

  6. 5. The influence of diel cycles on the bacterial community composition of two boreal lakes : A case study in Jämtland

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sofia Papadopoulou; [2021]
    Keywords : freshwater; lake; diel cycle; bacterioplankton; bacterial community composition;

    Abstract : In the Boreal region, the length of day and night varies extremely over the year and organisms are exposed to different diel (24 h) fluctuations of light and temperature. Among them are pelagic populations of bacteria that are ubiquitous in freshwater ecosystems. READ MORE
