  1. 11. Organic matter properties and their relation to phosphorus and nitrogen concentrations in Swedish agricultural streams

    University essay from SLU/Dept. of Soil and Environment

    Author : Betty Ehnvall; [2017]
    Keywords : dissolved organic matter; excitation-emission fluorescence spectroscopy; absorbance spectroscopy; eutrophication; biogeochemistry; absorbance index; fluorescence index;

    Abstract : Many agricultural streams in Sweden exhibit high concentrations of nitrogen, phosphorus, suspended sediments and dissolved organic matter (DOM). Together these substances cause eutrophication in streams, rivers and eventually the Baltic Sea. The interactions between different fractions of DOM and nutrients are not very well understood.

  3. 12. The impact of phosphorus and temperature on the toxicity of zinc on benthic diatom

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

    Author : Josabeth Ström; [2016]
    Keywords : benthic diatom; zinc; temperature; phosphorus; toxicity; ecological status;

    Abstract : The current index, IPS, developed for benthic diatoms and used for assigning the ecological status of streams in Sweden reflects on levels of nutrients and organic pollution. Metals are not considered in the index, which leads to the risk that metal contaminated streams can be assigned a high ecological status based on this index. READ MORE

  4. 13. Halomax® as a method for chromatin staining in cat sperm

    University essay from SLU/Dept. of Clinical Sciences

    Author : Agnes Sjödahl; [2015]
    Keywords : Halomax®; chromatin staining; spermatozoa; cat;

    Abstract : Wild felids all over the world are threatened by extinction. As a part of the preservation task concerning those species, in zoos as well as in situ in their wild habitat, the use of assisted reproduction technology (ART) is explored, e. g. artificial insemination (AI) and in vitro fertilization (IVF).
