ASSOCIATIONS BETWEEN WHITE SEA INVERTEBRATES AND OXYGEN-EVOLVING PHOTOTROPHIC MICROORGANISMS
https://doi.org/10.1234/XXXX-XXXX-2009-1-18-25
Abstract
Eleven species of White Sea invertebrates (sponges, actinians, hydroids, polychaetes and nudibranch molluscs) were tested for the presence of associated oxygen-evolving phototrophic microorganisms (OPM) (microalgae and cyanobacteria). Two main approaches were applied: a) light and electron microscopy of intact samples and fixed preparations of invertebrates, b) isolation of microorganisms from the invertebrate samples after mild surface sterilisation. The obtained results allow us to draw the conclusion on the formation of multi-component associations by White Sea invertebrates and OPM, based upon the following data: 1) the isolation of 27 cultures of OPM from eight species of invertebrates (sponges, hydroids, polychaete trochophore larva); 2) the species-specificity of association between epibiontic microorganism communities and macroorganisms within the same biotope; 3) spatial integration of micro- and macro-partners resulting in the formation of morphological structures within interorganismic contact zones.
