  1. 16. Spatial patterns of zooplankton communities In Swedish mountain and boreal lakes.

    Kandidat-uppsats,

    Författare :Juan Manuel de la Quintana; [2020]
    Nyckelord :Lake; zooplankton; phytoplankton; DOC and DIN:TP.;

    Sammanfattning :     Zooplankton is crucial for lake ecosystems as it is an important component in most of the food webs of these ecosystems. However, environmental changes have caused reductions in ecosystems nutrients and stoichiometry, which directly affects phytoplankton’s development and quality. LÄS MER

  4. 18. Nitrogen runoff, constructed wetlands and the effect on catch of fish in the Öresund strait

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Saga Hedstigen Sundblad; [2020]
    Nyckelord :seafloor oxygen demand; fish catch; constructed wetland; Earth and Environmental Sciences;

    Sammanfattning : Eutrophication and low dissolved oxygen levels are spreading all over the world, causing changes in fish distribution and decline in fish abundance and catch of fish. This study assesses the current nitrogen (N) surface runoff to the Öresund strait, the seafloor oxygen demand it cause, the subsequent effect on fish catch, and the constructed wetland area needed to retain current N loads.

  7. 20. Effekter av klimatförändringar på växtplankton i subarktiska och alpina sjöar

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Matilda Lundström; [2019]
    Nyckelord :Fosfor; Växtplanktonbiomassa; Diversitet; Oligotrofiering; Temperatur;

    Sammanfattning : 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. LÄS MER
