Cyanobacteria and cyanotoxins: the influence of nitrogen versus phosphorus.

PLoS ONE, 2012
The importance of nitrogen (N) versus phosphorus (P) in explaining total cyanobacterial biovolume, the biovolume of specific cyanobacterial taxa, and the incidence of cyanotoxins was determined for 102 north German lakes, using methods to separate the ...

The dominance of cyanobacteria in Mediterranean hypereutrophic lagoons: a case study of Cabras Lagoon (Sardinia, Italy)

Scientia Marina, 2011
An intense proliferation of cyanobacteria in Cabras Lagoon was investigated over a period of two years (July 2007 to June 2009). The influence of environmental and meteorological parameters in the lagoon on temporal variations in cyanobacteria orders was

Opening the Gap: Rare Lichens With Rare Cyanobionts – Unexpected Cyanobiont Diversity in Cyanobacterial Lichens of the Order Lichinales

Frontiers in Microbiology, 2021
The last decades of research led to a change in understanding of lichens that are now seen as self-sustaining micro-ecosystems, harboring diverse microbial organisms in tight but yet not fully understood relationships. Among the diverse interdependencies,

Morphological characterization of three subaerial Calothrix species (Nostocales, Cyanobacteria). [PDF]

Fottea, 2007
This paper characterizes and discusses the concept of species Calothrix braunii, C. capitularis spec. nova and C. parietina which were identified on subaerial rocky substrates in go rges of the Slovensk˝ raj National Park in Slovakia . In this paper, we focused on phenotypic characters, i.e. natural and cultural morphological variability.
