    Sammanfattning : Many cyanobacteria are reported to produce the nonprotein amino acid β-N-methylamino-L-alanine (BMAA). Cyanobacteria are extensively distributed in terrestrial and aquatic environments and recently BMAA was detected in temperate aquatic ecosystems, e.g. the Baltic Sea. LÄS MER

  3. 2. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

    Författare :Lesedi Lebogang; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microcystins; Drinking water; Adda-specific monoclonal antibodies; Biosensors; Capacitive; Amperometric; Flow-ELISA; Microcontact imprinting;

    Sammanfattning : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. LÄS MER

  4. 3. Copepods in Skeletonema-dominated food webs : Toxicity and nutritional quality as factors controlling copepod-diatom interactions

    Författare :Roswati Md Amin; Ulf Båmstedt; Sigrun Jónasdóttir; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copepod-diatom interaction; toxicity; nutritional quality; Skeletonema;

    Sammanfattning : My thesis focuses on copepod-diatom interactions, specifically on the effects of food quality and toxicity on copepod feeding, reproductive success and behavior but as a frame, also includes a quantitative evaluation of copepod carbon requirements compared to other trophic plankton groups. My aim was to evaluate the function of copepods in diatom-dominated spring blooms. LÄS MER
