1. 1. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Marta Holmlund; [2023]
   Nyckelord :wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

   Sammanfattning : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

3. 2. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Rebecca Paulina Dörner; [2023]
   Nyckelord :biodiversity; Nardus stricta; Nardus grassland; national park Hohe Tauern; East Tyrol; alpine pastures;

   Sammanfattning : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

4. 3. Reindeer grazing, soil wetness and aspect interact to drive tundra plant community structure in northern Sweden

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Emma Gemal; [2023]
   Nyckelord :tundra plants; vegetation; abiotic vs. biotic effects; community composition; diversity; reindeer herbivory; accelerometry; grazing;

   Sammanfattning : The relative importance of abiotic versus biotic top-down factors on structuring tundra plant communities is debated. With climate change already strongly affecting the tundra ecosystem, understanding which factors will prevail is vital. LÄS MER

5. 4. The effects of historical land use on plant diversity in semi-natural grasslands

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Elisabeth Kumlander; [2022]
   Nyckelord :semi-natural grasslands; biodiversity; plant species; land-use sequences;

   Sammanfattning : During the last two centuries, large-scale administrational and technological reforms have drastically changed the agricultural landscape in Sweden. The meadows and semi-natural grasslands that once played a central role in the agricultural landscape have been reduced with up to 95%. LÄS MER

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

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

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

   Sammanfattning : 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. LÄS MER
