The macroalgae nostoc zetterstedtii distribution and environmental demands

, : The macroalgae nostoc zetterstedtii distribution and environmental demands. Fauna och Flora Naturhistoriska Riksmuseet 81(4-5): 201-202

The blue-green macroalgae Nostoc zetterstedtii can rarely be found in oligotrophic clearwater lakes. An investigation has been carried out on many lakes, 18 of which were known to have contained Nostoc zetterstedtii in the 1920 s. On this occasion the algae was found in seven of these lakes. Eutrofication, acidification, and increasing supply of humus coming into the lake threatens the existence of the algae. Today there are 33 Swedish lakes which are known to contain Nostoc zetterstedtii.

The effect of dehydration, low temperatures and longwave UV light on the intensity of N fixation was studied in N. zetterstedtii Aresch. Dehydration caused a reduction in N fixation while long wave UV light stimulated N fixation. Both low temperat...

Excessive growth of seaweeds is a response of the biocenose, in a particular biotope, to a supply of nutrients. This supply may be natural or of anthropogenic origin. In the latter case, excessive growths and drifts of algae are consequences of th...; Wang Xian; Chen L.D.n; L.W.n Quan, 2003: The effects of environmental factors on macroalgae biosorption of heavey metals. The effects of pH and ionic strength on biosorption of heavy metal such as Cu2+, Pb2+, Cd2+ and Ni2+ were examined by two macroalgaes: Sargassum fusiforme and Laminaria japonica. The results showed that pH could affect the absorbent efficiency obv...
