  1. 1. How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Stina Stomberg; [2022]
    Keywords : brownification; eutrophication effects; drinking water; phytoplankton; Lake Bolmen; mesocosm; Earth and Environmental Sciences;

    Abstract : The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. READ MORE

  3. 2. The effects of eutrophication and browning on prey availability and performance of the three-spined stickleback (Gasterosteus aculeatus)

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Olivia Bell; [2021]
    Keywords : Baltic Sea; benthic habitats; body growth; climate change; coastal areas; diet; fish; stickleback; zooplankton;

    Abstract : Shallow coastal areas often have high productivity and diversity, in part due to the high availability of light and nutrients. At the same time, they are exposed to multiple environmental pressures, such as browning and eutrophication. READ MORE

  4. 3. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

    University essay from

    Author : Joel Fransson Forsberg; [2021]
    Keywords : Biopores; macropores; geoengineering earthworms; X-ray tomography;

    Abstract : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. READ MORE

  5. 4. Methane flux in the Doñana wetlands : Waterbird guano addition and benthicinvertebrate effects

    University essay from

    Author : Noa Ratia; [2019]
    Keywords : aquatic invertebrates; bottom-up effects; CH4; Doñana; greenhouse gases; mesocosm; methane; sediment cores; akvatiska evertebrater; bottom-up effekter; CH4; Doñana; mesokosm; metan; sedimentkärnor; växthusgaser;

    Abstract : Wetlands are globally important biogeochemical hotspots, and their roles as either significant sources of greenhouse gas or carbon sinks are strongly controlled by environmental drivers such as carbon, nitrogen, and phosphorus availability, which can stimulate emission of three greenhouse gases: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). Mounting evidence suggests that aquatic invertebrate activity can enhance wetland greenhouse gas flux, through bioturbation and bioirrigation of surrounding sediments. READ MORE

  6. 5. Transcriptomic profiling of marine bacteria between development and senescence phases of a phytoplankton bloom

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Dennis Amnebrink; [2018]
    Keywords : Transcriptomics; bacteria; microbes; DOM; marine environment; bioinformatics;

    Abstract : Bacterioplankton provide important ecosystem functions by carrying out biogeochemical cycling of organic matter. Playing an important role in the microbial loop they help remineralize carbon and nutrients. Bacteria also interact with phytoplankton during phytoplankton blooms. READ MORE
