  1. 6. What has happened on Swedish mires? The effects of drainage on vegetation changes over recent decades

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anna Ljungqvist; [2022]
    Keywords : peatlands; mires; bogs; fens; sweden; vegetation; plant ecology; time trend; data; nfi; nils; climate change; global warming; mosses; sphagnum; afforestation; trees; wetland; presence; coverage; drainage; ditch;

    Abstract : As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. READ MORE

  2. 7. Peatland restoration: A mossy affair? : The similarities of the vegetation communitiesbetween restored bogs and natural bogs.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Liesbeth van Ravenhorst; [2022]
    Keywords : Wetland; peatland; bog; vegetation composition; plant functional trait; environmental variable;

    Abstract : Peatlands function as important global carbon sinks as peatlands store 30% to 40% of the total soil carbon even though peatlands only cover 3% of the Earth's terrestrial surface. However, drainage activities have damaged the ecosystem and caused many peatlands to function as carbon sources instead. READ MORE

  3. 8. Drivers of decomposition across Sphagnum bog margins

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Emil Nordström; [2022]
    Keywords : Peatlands; tea bag index; edge effects; carbon storage; carbon sequestration; waterlogging; Torvmark; kanteffekter; kollagring; koldioxidbindning;

    Abstract : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter.

  4. 9. Development of a deep learning method for soil moisture estimation at high spatial and temporal resolution using satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nicklas Simonsen; [2021]
    Keywords : Physical Geography and Ecosystem Analysis; Machine Learning; Deep Learning; Recurrent Neural Network; LSTM; Soil Moisture; Remote Sensing; SAR; Sentinel-1; Sentinel-2; ISMN; ICOS: Geomatics; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) is an essential climate variable that controls fundamental hydrological and climatic processes. Soil moisture products derived from microwave remote sensing often provide measurements at low spatial resolution and incomplete temporal records. READ MORE

  5. 10. Assessment of the Contribution of Groundwater Flow and Surface Flow from Bolmsö Island to Lake Bolmen, Sweden

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Angelique Uwera; [2020]
    Keywords : Groundwater; Surface water; GMS-MODFLOW; Bolmsö Island; Lake Bolmen; Brownification.; Technology and Engineering;

    Abstract : The increase of brownification in surface waters has been a problem for rivers and lakes from the northern hemisphere. The main factors of this water brownification are the increase of dissolved organic matter and iron in water bodies. READ MORE
