  1. 1. The Influence of Macrophytes on Aquatic Microclimate

    Kandidat-uppsats, Stockholms universitet/Institutionen för ekologi, miljö och botanik; Stockholms universitet/Institutionen för biologisk grundutbildning (BIG)

    Författare :Julia Elliot; [2023]
    Nyckelord :;

    Sammanfattning : How terrestrial vegetation influences microclimate and what effects this has on associated ecosystems is well studied, but it is less known if and how aquatic macrophytes affect their microclimate. In this study I therefore aim to investigate the question of how aquatic macrophytes influence their microclimate, and how these effects in turn may affect associated aquatic organisms and ecosystems.

  3. 2. Habitatpreferens hos Anguilla anguilla: makrofyters påverkan på gulålars habitatval under dag och natt

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Hannah Wiklund; [2023]
    Nyckelord :European eel; Anguilla anguilla; Yellow eel; Habitat preference; Macrophytes; Substrate; Europeisk ål; Anguilla anguilla; Gulål; Habitatpreferens; Makrofyter; Substrat;

    Sammanfattning : Aquatic vegetation and different substrates can be important factors for fish habitat. The European eel (Anguilla anguilla) is threatened by habitat loss in freshwater systems during its life stage as a yellow eel. To conserve the species, restoration measures and increased knowledge about its preference for benthic habitats are needed. LÄS MER

  4. 3. Nutrients and biota in a lake system before and after restoration; a data analysis of the Swedish eutrophication case study Växjösjön

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Cleo Bakker; [2021]
    Nyckelord :sustainable development; eutrophication; phosphorus; internal loading; aluminum; biomanipulation;

    Sammanfattning : Eutrophication has proven to be a fundamental ecological problem for lakes and other bodies of water all around the world. The process of eutrophication can be defined as a lake containing increasing concentrations of nutrients from external and/or internal input over time. LÄS MER

  5. 4. Eutrophication effects on a coastal macrophyte community in the Bothnian Sea

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

    Författare :Emilia Linder Wiktorsson; [2021]
    Nyckelord :eutrophication; macrophytes; opportunistic algae; Baltic Sea; Bothnian Sea;

    Sammanfattning : Eutrophication is a major concern in the Baltic Sea and it is affecting macrophyte communities by promoting the growth of opportunistic algae and decreasing the cover of perennial macrophyte species via shading. It is however uncertain how common eutrophication and its symptoms are in the northern parts of the Baltic Sea, the Botnian Sea. LÄS MER

  7. 5. Population dynamics of the horned grebe in constructed wetlands in Östergötland.

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Johanna Pellnor; [2021]
    Nyckelord :Biodiversity; Canadian pondweed; Common roach; Horned grebe; Pike; Population dynamics; Wetland;

    Sammanfattning : The population size of the horned grebe, Podiceps auritus, is declining in most of the world due to loss of wetlands, deteriorating water quality and establishment of predatory fish such as pike, Esox lucius, in former fish free wetlands. The horned grebe is now globally classified as vulnerable. LÄS MER
