1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

2. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER
3. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. LÄS MER
4. En grön oas mellan stad och natur : ett växtgestaltningsförslag över Triangelplatsen i Stockholm med fokus på Nigel Dunnetts metodik för naturalistiska planteringar
Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Urbanisering, bostadsbrist och klimatförändringar är några av de faktorer som ställer högre krav på våra städer idag. Samhällen byggs i och med detta tätare och är i ständig omvandling för att anpassa sig till de problem som städerna ställs inför. I takt med urbaniseringen begränsas utrymmen till grönytor och grönska. LÄS MER
5. Modelling the Water Table in a Bog
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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.
