  1. 11. Initial evaluation of the combined effects of nanoplastics and 17α-ethinylestradiol on D. magna

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Tobias Henriksson; [2017]
    Keywords : daphnia magna nanoplastics nanoparticles 17α-ethinylestradiol ethinylestradiol combined effects; Earth and Environmental Sciences;

    Abstract : Exposure of combined pollutants is as of today not a very well-researched field of environmental science due to the complex interactions that may occur. Nanoplastic particles (NP) in particular are lacking studies due to the relatively new interest in the subject. READ MORE

  3. 12. Shape and dynamical consequences of the functional response of Daphnia magna

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Niklas Paulsson; [2013]
    Keywords : ;

    Abstract : The zooplankter genus Daphnia have been one of the most popular model organism for studies on population dynamics for a long time. Most models constructed as a part of these studies use a Type II Hollings functional response and whether the Type III response typeoccurs in Daphnia sp. or not has been the subject of debate.

  4. 13. The Effect of Synthetic Estrogen on Foraging and Predator Avoidance in the Common Roach (Rutilus rutilus)

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Gustaf Boström; [2012]
    Keywords : EE2; ecotoxicology; roach; rutilus; foraging; predator avoidance; Biology and Life Sciences;

    Abstract : Synthetic estrogens that originate mainly from oral contraceptive pills reach our waters through sewage effluent and potentially affect organisms in the natural environment. This study focused on the effects of the synthetic estrogen 17-alpha-ethinylestradiol (EE2) on the foraging and predator avoidance behaviors of the planktivorous fish roach (Rutilus rutilus), a common fish in Swedish lakes and rivers.

  5. 14. Optimization and validation of the method lactose intolerance genotyping with real-time PCR

    University essay from Uppsala universitet; Medicinska och farmaceutiska vetenskapsområdet; Medicinska fakulteten; Institutionen för medicinsk biokemi och mikrobiologi

    Author : Jenny Stenberg; [2011]
    Keywords : lactose intolerance; single nucleotide polymorphism; real-time PCR; genotype; optimization.;

    Abstract : Abstract Primary lactose intolerance has been associated with a single nucleotide polymorphism located upstream of the lactase gene. The most common diagnostic tests for lactose intolerance are time-consuming and the patient is not allowed to eat and drink for 12 hours before the test is carried out. READ MORE

  6. 15. Effects of food quantity, dietary fatty acids and temperature on fitness of Daphnia magna : a factorial experiment with Scenedesmus acutus and EPA amendments

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

    Author : Bernadette Pree; [2011]
    Keywords : Daphnia magna; temperature; Scenedesmus acutus; food quality; dietary fatty acid amendment; food concentration; pelagic food web;

    Abstract : The performance of zooplankton has a major impact on the efficiency in trophic transfer in pelagic food webs and is therefore examined in this study. I investigated the effect of different food quantity and food quality, as measured by omega-3 fatty acid (ω3-FA) content on survival, somatic growth and reproduction of Daphnia magna at high and low temperatures in laboratory growth experiments.
