1. 1. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Evelina Hansson; [2023-06-21]
   Keywords : benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

   Abstract : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). READ MORE

3. 2. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

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

   Author : Magnusson Petter; [2023]
   Keywords : Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

   Abstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

4. 3. Greenhouse gas emissions and carbon burial in a small pond

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Maria Carlson; [2023]
   Keywords : Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

   Abstract : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. READ MORE

5. 4. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : David Trulsson; [2023]
   Keywords : Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

   Abstract : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. READ MORE

6. 5. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

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

   Author : Anne Rebotzke; [2023]
   Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

   Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE
