  1. 1. Factors determining agricultural damage from foraging ungulates : an experimental study using exclosures in oat- and grass fields

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Markus Velin; [2021]
    Nyckelord :ungulates; foraging; biomass loss; NDVI; drones;

    Sammanfattning : Ungulates foraging on and damaging agricultural crops are a common phenomenon worldwide, which create conflicts between stakeholders with different economic interests. Further, the spatiotemporal distribution of food and the quality of food is often referred to as the “foodscape”. LÄS MER

  2. 2. Algal toxins in the Baltic blue mussel (Baltic Mytilus trossulus edulis) : spatiotemporal variations in the Baltic Sea

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Maya Ahlgren; [2021]
    Nyckelord :algal toxins; Mytilus trossilus edulis;

    Sammanfattning : Algal toxins have been found to bioaccumulate and have a seasonal variation over the summer months in marine biota. This can impact the food web through trophic transfer and the potential of using blue mussels for aquaculture. LÄS MER

  3. 3. Spatiotemporal variation in the relative fitness of a northern and a southern ecotype of Arabidopsis thaliana

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Jonathan Gyllingberg; [2021]
    Nyckelord :Arabidopsis thaliana; fitness; evolution; ecotype; genotype; flowering phenology; fecundity; local adaptation;

    Sammanfattning : Terrestrial plants exist in almost every habitat on the earth, ranging from warm and moist tropical rainforests, hot and dry deserts, and to cold and barren tundras. Furthermore, a single species may encounter different climatic conditionshabitats within its range distribution which climatic conditions differs from one to another. LÄS MER

  4. 4. Methane fluxes from tree stems in Amazon floodplains : Evaluating methodological aspect of measuring spatial and seasonal variability in a flooded system

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :felicia Widing; Nina Rubensson; [2018]
    Nyckelord :CH4; Tree stems; Amazon floodplain forest; Wetlands; flux; Solimões; Negro; Tapajós;

    Sammanfattning : Träd i tropiska våtmarker har uppmärksammats som en viktig källa till regionala och globala metan (CH4) utsläpp, då träd fungerar som utsläppskanaler för metan som bildas i sedimenten. Dock finns det en osäkerhet gällande säsongsvariation och rumslig variation samt mängden CH4 utsläpp från träd, eftersom kunskapen kring regionala flöden är begränsad. LÄS MER

  5. 5. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Johannes Larson; [2018]
    Nyckelord :dissolved organic carbon; DOC; export; boreal; specific discharge; spatiotemporal variation; löst organiskt kol; DOC; export; boreal; specifik avrinning; spatiotemporal variabilitet;

    Sammanfattning : The export of dissolved organic carbon (DOC) is an important component in both water quality and carbon cycling within boreal catchments. DOC exports are mainly controlled by discharge. LÄS MER
