Journal ArticleDOI
Rhodomonas lacustris (Pascher & Ruttner) Javornicky (Cryptomonadida): Ultrastructure of the Vegetative Cell
Journal ArticleDOI
The 18S and 28S rDNA identity and phylogeny of the common lotic chrysophyte Hydrurus foetidus
Dag Klaveness,Jon Bråte,Vishwanath Patil,Kamran Shalchian-Tabrizi,Ragnhild Kluge,Hans Ragnar Gislerød,Kjetill S. Jakobsen +6 more
TL;DR: Extending the taxon sampling to include nearly all available 18S chrysophyte sequences from cultured species and environmental DNA, this analysis placed H. foetidus within a separate, well-defined clade dominated by environmental sequences and poorly defined strains of chrysophtes in culture, mostly from cold environments.
Journal ArticleDOI
Marine-freshwater colonizations of haptophytes inferred from phylogeny of environmental 18S rDNA sequences.
TL;DR: The phylogeny demonstrates that haptophytes colonized freshwater on multiple independent occasions, including one of these colonizations, which gave rise to HAP‐1, the first molecular evidence of a freshwater species belonging to the class Pavlovophyceae.
Journal ArticleDOI
Rapid physicochemical changes in the high Arctic Lake Kongressvatn caused by recent climate change
Trine Marianne Holm,Trine Marianne Holm,Karin A. Koinig,Tom Andersen,Espen Donali,Anne Hormes,Dag Klaveness,Roland Psenner +7 more
TL;DR: In this article, the authors measured water chemistry and temperature from 2005 to 2010 in Kongressvatn, a crenogenic meromictic lake in Spitsbergen (Svalbard).
Journal ArticleDOI
Structure of extracellular polysaccharides produced by a soil cryptomonas sp. (cryptophyceae)1
TL;DR: Structural analyses showed that the Hindak strain of a Cryptomonas species (Cryptophyceae) produces extracellular polysaccharides, which appear to be a novel type of polymer in algae.
