1. Monitoring marine alien and invasive species. A comparison between the traditional method (eRAS) and DNA-based identification of species.
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : There is a major concern with the uncontrolled spreading of alien and invasive species, caused by an increase in travelling by boat globally. These are dispersed via ballast water, by fouling on ships and in fishing gear. LÄS MER
2. Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. LÄS MER
3. The ecological impact of artificial light at night in landscape architecture : strategies and guidelines for street lights for the benefit of biodiversity and local wildlife
Kandidat-uppsats, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Artificial light at night (ALAN) is an increasingly common form of light pollution that contributes to biodiversity loss, loss of dark habitats, disrupting populations both on an individual- and population level by invading biodiversity hot spots. Recent studies show that artificial light is increasing at a rate of approximately 6% annually over Earth’s surface, and 88% of Europe and 47% of the United States experience light pollution on a nightly basis.

4. Utvärdering av artificiell syresättning i syrefria bottenvatten och modellering av fjärden Slätbaken
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Östersjön är idag det system med störst utbredning av syrefattiga eller syrefria bottnar i hela världen. Problemet har uppstått som följd av den massiva näringsbelastning från de kringliggande länderna som pågått sedan industrialiseringen intensifierades på 1900-talet. LÄS MER
5. Evaluating an increased spill regime as a management tool to improve downstream passage of salmon smolt
Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : The anadromous Atlantic salmon (Salmo salar) is dependent on river connectivity to reach spawning and rearing habitats in rivers. Most rivers are today fragmented by artificial barriers such as hydroelectric powerplants (HEP) which impede this migratory movement. LÄS MER
