  1. 1. Top - down control: parasitism and predation on Gonyostomum semen in Swedish brown water lakes

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ingrid Bergman; [2022]
    Keywords : limnology; phytoplankton; top-down control;

    Abstract : Gonyostomum semen is a raphidophyte microalgae that can be found in brown water lakes all over Sweden. The species forms substantial summer blooms that can completely dominate the phytoplankton community, largely due to its limited grazing pressure. To test whether parasites control the abundance of G. READ MORE

  3. 2. When age makes all the difference : Methane production in sediment of contrasting Swedish lakes

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ursula Ronja Zellmer; [2020]
    Keywords : sediment; methane; limnology; biogeochemistry;

    Abstract : Lakes are a significant source of the powerful greenhouse gas methane (CH4) globally. Methaneis produced through microbial processes in anoxic sediments. Methane emission from lakes ishighly variable in space and time. READ MORE

  4. 3. Applied hyperspectral LIDAR for monitoring fauna dispersal in aquatic environments

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Klas Rydhmer; Alfred Strand; [2016]
    Keywords : Technology and Engineering;

    Abstract : This thesis work has been focused on evaluation and further development of a hyperspectral LIDAR (Light Detection And Ranging) system made by Ljungholm et. al. [1] for monitoring of aquatic fauna, and in particular zooplankton. READ MORE

  5. 4. Structural and Functional Changes in a Lake Bacterial Community Exposed to Multiple Stress Regimes

    University essay from Stockholms universitet/Stockholm Resilience Centre

    Author : Philipp Siegel; [2015]
    Keywords : bacterial community; microbial community; resilience; resistance; microbiology; environmental change; limnology; Sweden; Ekoln; bacterial productivity; enzyme activity; DOM; spectrometry; T-RFLP; NMDS; environmental fitting; microbial ecology;

    Abstract : Bacterial community resilience and resistance may play an important role in a world affected by climate change and increasing environmental disturbances. In this study we examined the resilience of a bacterial lake community from Lake Ekoln, Sweden, under increased environmental stress. READ MORE

  6. 5. Observation of methanogenesis and potential iron-dependent anaerobic oxidation of methane in old lake sediments, a study of two boreal forest lakes.

    University essay from Institutionen för biologisk grundutbildning

    Author : Elias Broman; [2013]
    Keywords : Limnology; Lake; Sediment; Methane; Anaerobic oxidation;

    Abstract : Organic and inorganic carbon can enter inland waters in different ways, and often a considerable amount of this carbon is coming from terrestrial input. Once this terrestrial carbon enters a lake, the carbon may be degraded, mineralized or eventually buried in the sediment. READ MORE
