Abstract

This article is the first comprehensive account about the occurrence of the cyanobacterium Nostoc pruniforme in Norway. The investigation was carried out in a rocky pool inhabited by the species. The locality is situated at the GPS-position: N.Lat. 71° 04' 657'', E. Long. 028° 14' 754'', in Slettnes nature reserve, Finnmark. The objectives of this study were to explore the organism in its limnological setting, and to throw light on autecological and synecological features together with the prevailing environmental conditions. The research work included studies both in the field and tha laboratory. For identification purposes isolation and purification of cyanobacteria were performed using culture techniques. The relevant strain of Nostoc pruniforme NIVA-CYA 648 is kept in the NIVA Culture Collection. This organism is available to members of the scientific community for non commercial purposes. Key words: Nostoc pruniforme, physiography, hydrobiology, growth and development, cellular complexity, conservation.
