1. 1. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Ayesha Nagahage; [2024]
   Keywords : Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

   Abstract : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

3. 2. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yanhe Zhou; [2023]
   Keywords : Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

   Abstract : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. READ MORE

4. 3. Potential migration routes for the alien species, pink salmon (Oncorhynchus gorbuscha) : investigating access in west and south coast rivers of Sweden

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Rebecca Martin; [2023]
   Keywords : invasive; alien species; salmonid; anadromous; migration barriers;

   Abstract : Invasive alien species are one of the main drivers of ecosystem change globally, presenting challenges to biodiversity that take many forms Pink salmon, Oncorhynchus gorbuscha, has recently been observed on the Swedish west coast where its presence is the result of secondary spreading from populations introduced to the White and Barents Seas in northwestern Russia. In Sweden, O. READ MORE

5. 4. TRACKING WASTEWATER EMISSIONS IN RIVERS ENTERING GULF OF BOTHNIA COAST

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Helen Mkandawire; [2023]
   Keywords : Nutrients inputs; wastewater; coastal waters; Gulf of Bothnia; wastewater emissions; nutrient transportation; marine water; nutrient loading; eutrophication.;

   Abstract : The Gulf of Bothnia consists of two sub-basins in the northern Baltic Sea: the Bothnian Sea (salinity 4-5‰) and Bothnian Bay (salinity 2-3‰). Changing nutrient concentrations and signs of eutrophication has recently been observed in the Gulf of Bothnia. READ MORE

6. 5. Hydrodynamic and Eutrophication Modelling of Lake Vomb: Impact of Future Climate Change on Cyanobacteria

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Ahmed Elhabashy; [2022]
   Keywords : Hydrodynamic modelling; eutrophication; Cyanobacteria; Chlorophyll-a; climate change; MIKE 3 FM; Lake Vomb;

   Abstract : The increasing frequency of Cyanobacterial blooms in freshwater bodies raise concerns around the globe. The consequences of this phenomenon impact not only human health but the entire surrounding ecosystem. During the past decades, numerical modelling has been increasingly used to investigate and study aquatic systems. READ MORE
