Dolichospermum uruguayense sp. nov., a planktic nostocacean cyanobacterium from the Lower Uruguay River, South America
Resumen:
Massive cyanobacterial blooms frequently occur in the Uruguay River, one of the largest rivers in South America. A heterocytous morphospecies of unique morphology has been repeatedly observed in the river since 2006 in rather high abundances. This morphospecies was preliminarily reported as Anabaena spiroides and Dolichospermum cf. pseudocompactum, but its morphology does not fully correspond with the description of these species, neither with definitions of any Dolichospermum species described so far. A clonal strain designated “strain7” was isolated in 2010 from the Lower Uruguay River and thoroughly characterised from morphological and phylogenetic points of view. An establishment of D. uruguayense spec. nov. was proposed.
