11. Flodpärlmusslans (M. margaritifera) förekomst och täthet genom NPK+ och blå målklassning : En studie i Kolarebäcken – Västra Götalands län
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Majoriteten av Sveriges vattendrag observeras i skogsmark, där en god skogsbruksplanering kan förbättra vattenkvaliteten. Världsnaturfonden (WWF) konstruerade således verktygen Naturvärden, Påverkan, Känslighet och Plusvärde (NPK+) och Blå målklassning, vilka har utvecklats av skogsstyrelsen. LÄS MER
12. Copper bioaccumulation in blue mussels and periwinkles from marinas
Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : Copper (Cu) is a heavy metal that is essential for life but toxic at high concentrations. This toxic effect is used on boats to prevent biofouling on boat hulls by painting the hulls with antifouling paint that contain high levels of Cu. The Cu is slowly diffused out in the water and accumulated by animals higher up in the food chain. LÄS MER
13. Using Blue Mussels as a Tool for Mitigating Eutrophication in the Baltic Sea
Master-uppsats, Linköpings universitet/Industriell miljöteknikSammanfattning : Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. LÄS MER
14. Can the native shore crabs (Carcinus maenas) become a barrier to the invasion of the round goby (Neogobius melanostomus) in Öresund, southern Baltic Sea?
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : The round goby (Neogobius melanostomus) is a non-indigenous species to the Baltic Sea that has drawn the attention of many researchers in the last decade due to its rapid spreading and its impact on the local fauna. With recent concerns about the dispersal of the round goby towards the North Sea, the aim of this study was to determine if the native shore crab could compete with the invaders and prevent their advance.

15. Fatty acid composition of black soldier fly larvae : impact of the rearing substrate
Master-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : With an increasing world population and meat consumption the black soldier fly (BSF; Hermetia illucens) shows potential as feed for animals, while recycling nutrients from food waste. To produce larvae of high quality as animal feed, further understanding is needed of how the substrate affects the nutritional composition of the larvae. LÄS MER
