  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. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Linnéa Eriksson; [2023-04-20]
    Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

  4. 3. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

  5. 4. Characterization and optimization of Rhodosporidium toruloides for production of lipids

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Niharika Singh; [2021]
    Keywords : chemical engineering; oily yeasts; lipids; nitrogen limitation; Technology and Engineering;

    Abstract : Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. READ MORE

  6. 5. Designing the Superplant: Increasing Lipid Signaling for Enhanced Phosphorus Uptake

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Author : Louise Jedemark; [2021]
    Keywords : Lipid flippases; Arabidopsis; Yeast; Transport biology; Applied Biochemistry; Tillämpad biokemi; Biology and Life Sciences; Technology and Engineering;

    Abstract : Phosphate is fundamental for optimal growth and reproduction for plants. However, due to low solubility, not all phosphorus in the soil is available to the plant. It has recently been discovered that plants can take up complex phosphate-containing organic compounds, such as phospholipids. READ MORE
