  1. 1. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Rashid Kadhim; [2022]
    Keywords : lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

    Abstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE

  2. 2. 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. 3. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Melinda Rydberg; [2022]
    Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

  4. 4. Efficiency of diatom and flagellate-based marine food webs.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Yasmina Hamladji; [2021]
    Keywords : phytoplankton; flagellate; diatoms; ciliates food web efficiency; fungi;

    Abstract : Aquatic microbial food webs are in general size structured. Phytoplankton, which constitute the base of the food web, are grazed by protozoa and mesozooplankton, which in turn are consumed by planktivorous fish. Food web efficiency (FWE) is a measure of how efficiently energy is transported up the food web. READ MORE

  5. 5. 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
