  1. 6. Soil Carbon Stocks in Old Growth Forest : Drivers of variability in soil organic carbon stocks in old growth boreal forests

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elis Ingvarsson; [2023]
    Keywords : old growth forest; boreal; soil organic carbon stocks; climate gradient;

    Abstract : Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, which plays an important role in climate change by regulating atmospheric carbon dioxide. Sweden’s forest management has led to a decrease in old growth forests. This change in land use can affect SOC levels in these forests. READ MORE

  3. 7. Seasonal variation of LAI in Swedish coniferous forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ilia Mastepanov; [2023]
    Keywords : leaf area index; LAI; PAR; forest; coniferous forest; Hyltemossa; Earth and Environmental Sciences;

    Abstract : Leaf Area Index (LAI) is quantity representing the amount of foliage in the canopy, which makes it an important parameter for analysing terrestrial ecosystems. Traditional methods of measuring LAI were done by analysing hemispherical photographs by hand and were very time consuming, requiring specific weather conditions (Jonckheere et al. 2004). READ MORE

  4. 8. The Influence of Macrophytes on Aquatic Microclimate

    University essay from Stockholms universitet/Institutionen för ekologi, miljö och botanik; Stockholms universitet/Institutionen för biologisk grundutbildning (BIG)

    Author : Julia Elliot; [2023]
    Keywords : ;

    Abstract : 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.

  5. 9. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Yang Foo; [2023]
    Keywords : earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

    Abstract : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. READ MORE

  6. 10. To clear-cut or not to clear-cut; Cost-benefit analyses of post-fire management approaches in the Ljusdal fire-complex

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Bella Blomqvist; [2023]
    Keywords : Clear-cut forestry; Continous cover forestry; Nature reserve; Cost-benefit analysis; Wildfires; Sweden; Ljusdal; Post-fire management; Earth and Environmental Sciences;

    Abstract : Wildfires causes natural disturbances to ecosystems which can have potentially damaging results for ecosystem services and economic income from timber production. The post-fire management approach can be essential for the environmental work regarding the recovery of ecosystems and maintaining ecosystem services. READ MORE
