  1. 31. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ignacio Martínez Casasús; [2021]
    Nyckelord :Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Sammanfattning : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). LÄS MER

  3. 32. Undersökning av tidigt varningssystem för algblomning : -en studie genom vattenkvalitetsmätningar med EXO2 sond, fjärranalys och vattenprovtagning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Limnologi

    Författare :Harald Löf; [2021]
    Nyckelord :fjärranalys; algblomning; cyanobakterier; varningssystem; multiparametersond;

    Sammanfattning : Algal blooms can pose a serious threat to humans and animals in lakes used for drinking water and recreation in the bloom contains toxin producing cyanobacteria. Early warning of impending algal blooms requires systems with high temporal resolution. LÄS MER

  4. 33. The effects of eutrophication and browning on prey availability and performance of the three-spined stickleback (Gasterosteus aculeatus)

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Olivia Bell; [2021]
    Nyckelord :Baltic Sea; benthic habitats; body growth; climate change; coastal areas; diet; fish; stickleback; zooplankton;

    Sammanfattning : Shallow coastal areas often have high productivity and diversity, in part due to the high availability of light and nutrients. At the same time, they are exposed to multiple environmental pressures, such as browning and eutrophication. LÄS MER

  5. 34. Predicting biodiverse semi-natural grasslands through satellite imagery and machine learning

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Adrian Baggström; [2021]
    Nyckelord :Machine learning; remote sensing; biodiversity; plant species richness; semi-natural grasslands; Sentinel-2;

    Sammanfattning : Semi-natural grasslands are amongst the most biodiverse ecosystems in Europe, though their importance they are experiencing a declining trend. To monitor and assess the health of these ecosystems is generally costly, personnel demanding and time-consuming. LÄS MER

  7. 35. Responses in river water quality during summers with extreme weather periods in Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Felicia Claeson; [2021]
    Nyckelord :water quality; rivers; Europe; extremeweather periods; drought; heatwave; floods; dissolved oxygen; nitrate; chlorophyll-a; phosphate; Earth and Environmental Sciences;

    Sammanfattning : Europe has experienced several climate extremes during the past decades. These extreme events have increased in number and intensity and are projected to further intensify. Previous studies show that heatwaves, drought, and flood can have an impact on water quality in several ways. LÄS MER
