  1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

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

    Författare :Ayesha Nagahage; [2024]
    Nyckelord :Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Sammanfattning : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  3. 2. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yanhe Zhou; [2023]
    Nyckelord :Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

    Sammanfattning : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. LÄS MER

  4. 3. Åtgärdsuppföljning inom vattenförvaltning - Praktisk implementering av lokalt förvaltningsarbete vid Vombsjön

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Vera Sandell; [2022]
    Nyckelord :water management; monitoring; follow-up; Vombsjön; chemical status; ecological status; evaluating effectiveness; eutrophic lake; agricultural landscape; Earth and Environmental Sciences;

    Sammanfattning : Clean drinking water is often taken for granted. However, the lake that supplies the greater part of southwestern Scania with drinking water has severe environmental problems regarding the chemical and ecological status. LÄS MER

  5. 4. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wiebke Coenen; [2022]
    Nyckelord :Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Sammanfattning : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. LÄS MER

  7. 5. Spatial resolution of methane production and ebullition in Lake Alsta

    Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Evelina Hiltunen; [2021]
    Nyckelord :methane; ebullition; TN;

    Sammanfattning : 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. LÄS MER
