1. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive
Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. LÄS MER
2. Sensitivity of Norway Spruce (Picea abies) to inundation.
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER
3. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing
Master-uppsats, SLU/Dept. of EcologySammanfattning : 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.

4. Ecosystem services from woody vegetation in East African rangelands
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER
5. Rosendalsängen på Djurgården : en restaurering med naturalistiska planteringsprinciper
Master-uppsats, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Bevarandet av historiska parker och trädgårdar är en viktig del av förvaltningen av det kulturhistoriska arv som finns i den bebyggda miljön, både i urbana och mer naturnära kontexter. Forskning har visat att det inom historiska trädgårdsanläggningar finns en anmärkningsvärt hög biodiversitet och att dessa platser därför kan spela en viktig roll i den hållbara utvecklingen eftersom de ofta är lagstadgat skyddade från exploatering till skillnad från övrig grönyta i städerna.
