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

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

    Författare :Rashid Kadhim; [2022]
    Nyckelord :lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

    Sammanfattning : 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. LÄS MER

  3. 2. Changes in the fish community in Lake Tåkern, Sweden - a comparison between 1978-1979 and 2019

    Master-uppsats, Linköpings universitet/Biologi
