  1. 1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  3. 2. The importance of bacterial functional diversity for mixotrophic flagellate function

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Simon Wentritt; [2023]
    Nyckelord :Mixotrophs; Functional Diversity; Algae Culturing;

    Sammanfattning : This project examined the role of functional diversity of bacterial prey organisms on a mixotrophic flagellate’s function. The concept of functional diversity and its role for ecosystem functioning is a subject of ongoing research and controversially discussed. Mixotrophy is the combination of different modes of nutrition in one organism. LÄS MER

  4. 3. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Marta Holmlund; [2023]
    Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Sammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  5. 4. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
    Nyckelord :LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Sammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER

  7. 5. Ekologisk funktionalitet i Malmö : En jämförande undersökning av biodiversitet i Varvsparken & Strandparken

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Emma Flokén; Sofia Maria Cato; [2023]
    Nyckelord :Urban biodiversity; ecological functionality; trees; birds; vegetation; Urban biodiversitet; ekologisk funktionalitet; inventering; fåglar; träd; vegetation;

    Sammanfattning : Ett stort hot mot biologisk mångfald är urbaniseringen, då utbyggnad av städer leder till attplatser som tidigare utgjort viktiga habitat ersätts av hårdgjorda ytor, byggnader och mänskligaktivitet. Det finns ett nytt tankesätt inom stadsplanering, nämligen förtätning. LÄS MER
