16. ADAPTED FISH FRIENDLY OPERATION OF SMALL-SCALE HYDROPOWER PLANTS : AN ECONOMIC ANALYSIS
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : The hydropower sector generates almost half of the electricity produced in Sweden annually. Although hydropower is a renewable energy that produces no emissions, there is an impact on the local scale of Swedish aquatic ecosystem causing the decline of some fish species due to its impact on rivers connectivity.

17. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

18. Biodiversity and habitat conditions in reaches with high flow velocity along gradients in hydrological and geomorphological alteration : A study of six rivers in Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The vast majority of rivers in the developed world are affected by human alteration, which in turn negatively affects the species that rely on these highly diverse and species rich areas to survive. Homogenization of previously heterogenic areas due to a change in water discharge and the substrate availability in the rivers is often regarded as the main reason for the loss of species richness in rivers and the riparian zone.

19. Quantifying the state of the coral reef ecosystem in relation to biophysical benthic and pelagic indicators and biological drivers of change in the Saba National Marine Park, Dutch Caribbean
University essay from SLU/Dept. Of Aquatic ResourcesAbstract : Coral reefs are experiencing large scale degradation. Motivated by the need for regular data monitoring and for quantification of the state and change of benthic and pelagic organisms, the Global Coral Reef Monitoring Network protocol was executed on 18 dive sites in fished and unfished areas around the island of Saba in the Saba National Marine Park (SNMP) in the Dutch Caribbean from March to May 2019.

20. Digitizing and Mapping Channel Heads Across Various Forested Regions in Sweden Using a High-Resolution DEM : A Regional Analysis of How Landscape Properties Influencing Channel Head Initiation
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Acting as a hydrological link between the terrestrial landscape and the larger downstream river network, channel heads and their immediate headwaters are essential geomorphological features in our landscape. Not only due to their ability to transport water and sediment and cycling of nutrients, but as an important component for ecosystem productivity and aquatic habitats. READ MORE
