  1. 6. Spatial patterns of zooplankton communities In Swedish mountain and boreal lakes.

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

    Author : Juan Manuel de la Quintana; [2020]
    Keywords : Lake; zooplankton; phytoplankton; DOC and DIN:TP.;

    Abstract :     Zooplankton is crucial for lake ecosystems as it is an important component in most of the food webs of these ecosystems. However, environmental changes have caused reductions in ecosystems nutrients and stoichiometry, which directly affects phytoplankton’s development and quality. READ MORE

  3. 7. Nutrient distribution by mammalian herbivores in Hluhluwe-Imfolozi Park (South Africa)

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Laura van Veenhuisen; [2018]
    Keywords : megaherbivores; nutrient distribution; stoichiometry; South Africa; Hluhluwe–Imfolozi Park; African savannah; herbivores; wildlife ecology; dung;

    Abstract : African megaherbivores are ecosystem engineers, which are under threat of extinction caused by, among others, poaching and climate change. Their current rates of loss means that there’s a need to better analyse their impact on the environment, in order to predict the consequences of losing this group. READ MORE

  4. 8. Multiplexing microarrays with OSTEmer-biosticker : From polymer fabrication to bio analysis

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sihui Chen; [2017]
    Keywords : Microfluidics; microarray; OSTEmer; biosticker; multiplexed; Mikrofluidika; mikroarray; OSTEmer; biosticker; multiplexade;

    Abstract : Microarray technology provides powerful tools in the field of biomedicalresearch because it can measure molecular interactions in a highly parallelfashion. It has uses in protein, DNA or cell research, in both discovery anddiagnostic applications. READ MORE

  5. 9. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Jonatan Fast; [2017]
    Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  6. 10. Population demography’s potential effect on stoichiometry : Assessing the growth rate hypothesis with demography

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

    Author : Alexander Blochel; [2017]
    Keywords : Demography; insect populations; stoichiometry; growth rate hypothesis;

    Abstract : The elemental composition within structured insect populations was tested by creating a new method to analyze how variables (survival, growth and fecundity) within a population matrix could potentially affect the stoichiometric regime of a structured population at steady state. This was done by focusing on if the growth rate hypothesis, which states that there is a linear relationship between an individual growth rate and the percent of phosphorus within the individual, works at a population level.
