About Sten-Åke Wängberg

Research Marine microbial ecology, especially, how changes in environmental factors affect structure and function of microalgal communities. The research is focused on the effects of ultraviolet radiation but includes also the effects of toxic compounds. Experimental system used includes techniques to describe long-term changes as well as acute effects on functional parameters. Together this gives information about the significance of the acute effects for the long-term, ecological, changes. The functional parameters used are, primarily, photosynthesis and bacterial production. Structurally communities and populations are characterized as cell numbers, species and chemical composition (pigments, fatty acids, carbon nitrogen, phosphorus etc.) to identify differences between communities and give information of the value of the microorganisms as food for higher trophic levels. The research is performed with cultures in the laboratory and in the field, on the Swedish west coast and in polar areas.
