  1. 16. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Martina Stangl; [2022]
    Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

    Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE

  3. 17. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliane Glinski; [2022]
    Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Abstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

  4. 18. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Anna Engman; [2022]
    Keywords : peatland; peat volume change; ecohydrology; specific storage; peatland age; torvmark; myr; torvvolymförändring; ekohydrologi; specifik magasinkoefficient; ålder;

    Abstract : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. READ MORE

  5. 19. Anaysis of the Trend of Historical Temperature and Historic CO2 Levels Over the Past 800,000 Years by Short Time Cross Correlation Technique

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Tejashkumar Patel; [2021]
    Keywords : Short time crosscorrelation technique; CO2; temperature data;

    Abstract : Carbon Dioxide concentration in Earth’s atmosphere is currently at 417 Parts permillion (ppm) and keep rising. Historic CO2 levels and historic temperature levels hasbeen cycling over the past 800,000 years. READ MORE

  6. 20. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lukas Rehn; [2021]
    Keywords : Boreal catchments; carbon cycling; carbon dioxide; DIC; headwater streams; Krycklan Catchment Study; trend analysis;

    Abstract : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.
