  3. 3. Circadian rhythms and carbon acquisition in the red algae Kappaphycus alvarezii and Eucheuma denticulatum

    Author : Malena Granbom; Matt Dring; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysiologisk botanik; Physiological Botany;

    Abstract : Aspects of carbon and nitrogen metabolism have been studied in two closely related tropical red macroalgae (Rhodophyta) that belong to the commercially important genera Kappaphycus and Eucheuma. These algae are cultivated around the world for their carrageenan content. READ MORE

  4. 4. Stable isotope studies of contaminant and material transport in Baltic pelagic food-webs

    Author : Carl Rolff; Nicholas J.P Owen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

    Abstract : Both carbon and nitrogen appear in nature as different stable isotopes. Many natural processes affect the relative proportions of heavy and light isotopes in predictable ways. The isotopic composition of organisms and other organic materials can therefore serve as records of the processes involved in their formation. READ MORE

  5. 5. Zooplankton response to cyanotoxins

    Author : Susanne Gustafsson; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; cyanotoxins; maternal effects; algal toxins; zooplankton; tolerance; cyanobacteria;

    Abstract : Mass development of cyanobacteria (blue-green algae) is common in many lakes and coastal waters worldwide as a result of an increased nutrient loading. These blooms of cyanobacteria are undesirable for several reasons; thick mats of algae and unpleasant odour reduces the recreational values, bad taste reduces the quality of drinking water and the potent toxins produced by some species of cyanobacteria endanger human health.
