Karlsona,*, Francisco J.A. Nascimentoa, Sanna Suikkanenb, Ragnar Elmgrena a Department b of Systems Ecology, Stockholm University, SE-10691 Stockholm, Sweden Thus far, the negative effects of Nodularia spumigena blooms on aquatic organisms have been mainly attributed to the production of the hepatotoxic nodularin (NOD). In the current work, the accumulation of other N. spumigena metabolites in blue mussels and crustaceans, and their effect on Thamnocephalus platyurus and Artemia franciscana, were examined. High pH and not allelopathy may be responsible for negative effects of Nodularia spumigena on other algae. Aquatic Microbial Ecology, 2006.

Nodularia spumigena effects

N. spumigena causes harmful algal blooms in many parts of the world including Australia. Effects of toxic cyanobacteria on a plankton assemblage: community development during decay of Nodularia spumigena Jonna Engström-Öst1,2,*, Marja Koski2,3,**, Katrin Schmidt4, MarkkuViitasalo1, Sigrún H.

Although none of the bacterial isolates showed strong algicidal effect, the observed stimulatory and retarding effects on N. spumigena growth under culture conditions denotes the importance of the associated bacterial community for the dynamics of these cyanobacterial populations in nature. Accumulation and effects of nodularin from a single and repeated oral doses of cyanobacterium nodularia spumigena on flounder (platichthys flesus L.) Pekka J. Vuorinen, Vesa O.

Significant stimulation of the quantum efficiency of photosystem II (up to 100%) also indicated photosynthetic performance as a main target of iron fertilization. Effects of NODLN on FlounderThe administration of NODLN by force-feeding into flounder, either as a single high dose 4 days before sampling or as three smaller doses 3 days apart, clearly caused some hepatocellular damage.

The variables studied here did not show any effects of NODLN. However, other chemical methods such as enzymatic activity may disclose effects of NODLN.
