1. Cyanobacteria in marine environments
Cyanobacteria in freshwater environments have been
long known for their environmental impact, especially in
conjunction with explosive reproduction of toxic strains in
plankton blooms (Whitton and Potts, 2000). Many of these
cyanobacteria represent hazard to humans (Bell and Codd,
1994) and domestic animals (Gunn et al., 1992; Negri et al.,
1995). Formation of cyanobacterial blooms is associated
with eutrophication and pollution in lakes and rivers.
Similar imbalance in nutrient supply when transferred to
marine environments is less predictable, where coastal
eutrophication is often causing red tides, which are usually
dominated by dinoflagellates (e.g. Lobel et al., 1988).
