  1. 16. Effekter av klimatförändringar på växtplankton i subarktiska och alpina sjöar

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Matilda Lundström; [2019]
    Keywords : Fosfor; Växtplanktonbiomassa; Diversitet; Oligotrofiering; Temperatur;

    Abstract : The aim of this report was to determine how the climate change affects the ecosystems in alpine and subarctic lakes in Sweden. This was done by analyzing data from environmental monitoring of 14 subarctic and alpine lakes that was part of the national time-series lake monitoring program. READ MORE

  3. 17. Records of environmental change and sedimentation processes over the last century in a Baltic coastal inlet

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hanna Nilsson; [2019]
    Keywords : Baltic Sea; eutrophication; coastal areas; archipelago; laminated sediments; nutrient inputs; carbon and nitrogen content; biogenic silica; sedimentation; environmental impact; marine geology; Earth and Environmental Sciences;

    Abstract : The marine ecosystem in the Baltic Sea is affected by multiple stress factors, e.g. eutrophication and deoxygenation, overfishing and anthropogenic pollution. Here we evaluate the short-term trends of dissolved oxygen in bottom waters and changes in the primary productivity within a coastal inlet in the Baltic Sea. READ MORE

  4. 18. Adaptive Evolution of Resource Use, Phenotypic Diversity, and Productivity of Phytoplankton Communities

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Hellekant; [2019]
    Keywords : Adaptive Dynamics; phenotype; phytoplankton; plankton; BEF; Biodiversity; diversity; Spatial modeling; Ecosystem function; Evolution; Diversity;

    Abstract : There is growing concern that the worldwide loss in biodiversity will harm the stability of the ecosystems, and thereby, the carrying capacity and critical ecosystem services the biosphere provides. Phytoplankton (microalgae) in lakes and oceans are arguably the most important primary producers. READ MORE

  5. 19. Lake biology as a function of catchment characteristics and water quality parameters – focus on phytoplankton

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Jenny Näslund; [2019]
    Keywords : phytoplankton; total phosphorus; catchment; soil properties; land use; agriculture; water framework directive; ecological status;

    Abstract : According to the EU Water Framework Directive, phytoplankton should be included for assessment of the ecological status of lakes. Phytoplankton respond rapidly to environmental changes and are a particularly good indicator of nutrient loads. READ MORE

  6. 20. Using Blue Mussels as a Tool for Mitigating Eutrophication in the Baltic Sea

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Johanna Ståhle; Linnea Henriksson; [2018]
    Keywords : Life cycle analysis LCA ; recycling of nutrients; blue mussels; mussel farm; mussel meal; biogas; compost;

    Abstract : Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. READ MORE
