  1. 21. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

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

    Author : Lara Sánchez Calderón; [2022]
    Keywords : aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Abstract : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. READ MORE

  3. 22. Odlade torvjordar och växthusavgång : effekter av pH, temperatur och vattenhalt

    University essay from SLU/Dept. of Soil and Environment

    Author : Lisette Nordgren; [2021]
    Keywords : odlad torvjord; pH; kalk; växthusgaser;

    Abstract : Torvmarker utgör potentiella sänkor av växthusgaser (VHG) och täcker en betydande andel av Sveriges yta. Förra seklet dikades en stor del av markerna för odling m.m. vilket i nutid har lett till en ökande problematik med mikrobiell nedbrytning och torvförlust. READ MORE

  4. 23. Assessment of how environmental variables and vegetation structure influence peatland carbon fluxes

    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

  5. 24. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ines Júlio Alfredo; [2021]
    Keywords : Sentinel 2; Vegetation Indices; Ground Sensors; Drought and Mire; Earth and Environmental Sciences;

    Abstract : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. READ MORE

  6. 25. Post-fire community changes in peatland dwelling beetles : A before-after-control impact study of beetle communities in Swedish mires after a megafire

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Janina Happ; [2021]
    Keywords : Coleoptera; Mires; Peatlands; Wildfire; Forestfire; Megafire;

    Abstract : As a consequence to climate change and resulting severe weather events such as prolonged hot and dry periods, wildfire frequency increases globally. Progressively, these effects are noticeable in high latitude countries such as Sweden where a megafire burned 13 100 ha of managed coniferous forest in 2014. READ MORE
