Grazers and Associated Organisms of Trichodesmium

摘要: Colonies of the pelagic cyanobacterium Trichodesmium consist not only filamentous trichomes, but other types associated organisms as well, including bacteria, diatoms, dinoflagellates, fungi, protozoa, hydrozoans and copepods. These use a physical substrate food source. Pelagic harpacticoid copepods (the genera Macrosetella Miracia in particular), are that have been quantitatively shown to There anecdotal reports feeding on salps, crabs fish. micro-communities, with tight nutrient coupling, may be an adaptation for existence oligotrophic tropical subtropical seas. Associated cause physiological changes Trichodesmium, which could account much inter-colony variation when measuring various parameters this cyanobacteria. can make significant contribution “new production” nitrogen flux organic matter from surface waters. Therefore, consumption fate has important consequences understanding inputs outputs carbon open ocean.
