1. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

2. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE

3. 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 landskapsläraAbstract : 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

4. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

5. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. READ MORE
