1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER
2. The importance of bacterial functional diversity for mixotrophic flagellate function
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : This project examined the role of functional diversity of bacterial prey organisms on a mixotrophic flagellate’s function. The concept of functional diversity and its role for ecosystem functioning is a subject of ongoing research and controversially discussed. Mixotrophy is the combination of different modes of nutrition in one organism. 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. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways
Master-uppsats, Linköpings universitet/Industriell miljöteknikSammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER
5. Ekologisk funktionalitet i Malmö : En jämförande undersökning av biodiversitet i Varvsparken & Strandparken
Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)Sammanfattning : Ett stort hot mot biologisk mångfald är urbaniseringen, då utbyggnad av städer leder till attplatser som tidigare utgjort viktiga habitat ersätts av hårdgjorda ytor, byggnader och mänskligaktivitet. Det finns ett nytt tankesätt inom stadsplanering, nämligen förtätning. LÄS MER
