Concept URI http://eunis.eea.europa.eu/eunishabitats/A5.52M
Preferred label Pontic [Phyllophora nervosa] biocenosis on shell gravel
Definition The dominant species is the alga [Phyllophora nervosa]. In addition to the dominant species there are three other species of Phyllophora: [Phyllophora brodiaei], [Phyllophora pseudoceranoides], [Phyllophora trallii]. There are 118 species of invertebrates in the Phyllophora field the most characteristic of which are: [Bittium reticulatum], [Harmothoe imbricata], [Balanus improvisus], [Synisoma capito] (Zaitsev and Alexandrov 1998). Studies conducted in the NW shelf area (Zernov's Phyllophora field) indicated tht the mass macrozoobenthos species are: the bivalve mollusc [Mytilus galloprovincialis], [Mytilaster lineatus], the gastropod [Rissoa parva], the barnacle [Balanus improvisus] and the polychaete [Nereis succinea]. In Egorlitsky Bay the mass species are [Mytilaster lineatus], [Nereis zonata] and [Platynereis dumerilii]. Studies conducted along the Romanian coast (Vailiu and Bodeanu, 1972) indicate that [Phyllophora nervosa] and [Phyllophora brodiae] are present between 10-56 m with highest biomass recorded in the northernmost part of the Romanian coasts, at 43-46 m depth where the presence of [Phyllophora brodiae] is favoured by the presence of a particular substrate given by the massive development of calcareous algal concretions of the red alga [Lithothamnion] present on bivalve shells (Vasiliu and Bodeanu, 1972). In Romanian waters, in the area known as Zernov's Phyllophora field, the fauna is composed mostly of [Mytilus galloprovincialis] up to 20-30 meters depth, and [Modiolus phaseolinus] at depths exceeding 30 meters (Tiganus, 1991-1992).
