  1. 1. Modelling the Water Table in a Bog

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Bowley; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. 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

  4. 3. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

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

    Author : Emilie Åström; [2022]
    Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

    Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

  5. 4. 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

  6. 5. Assessment of how environmental variables and vegetation structure influence peatland carbon fluxes

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Bernabé Ramírez; [2021]
    Keywords : ;

    Abstract : Boreal peatlands are important ecosystems from a carbon balance perspective because they are natural carbon sinks as a result of millennia of peat formation. However, due to climate change, these ecosystems are susceptible to changes in hydrology and temperature. READ MORE
