A1.14 - Biocénoses de la roche médiolittorale inférieure très exposée à l'action des vagues de Méditerranée et de la mer Noire

Mediterranean and Black Sea communities of lower mediolittoral rock very exposed to wave action

Classification des habitats EUNIS

Descriptif officiel

These communities are located in the lower horizon of the mediolittoral rock and result from the concomitance of three components: high waves, variations in atmospheric pressure, and variations in wind and tide. The dominant aspect, however, is the constant humidity of the substratum.

Descriptif en français

Cette biocénose se situe au niveau de l’horizon inférieur de la roche médiolittorale et résulte de la conjonction de trois facteurs : présence de vagues, variations de la pression atmosphérique, des vents et des marées. Le facteur dominant est l’humectation constante du substrat.

Remarques

There is a certain degree of duplication among some habitat classes in the EUNIS system coming either from BioMar or the Barcelona or HELCOM classifications. Therefore this means that all level 4 definitions (presently based on BioMar and Barcelona) should be checked, and given a new name if necessary. The biogeographic details are to be addressed in level 5 habitats.
Zonal basis of habitats in Barcelona units is different from that of BioMar (life-type). May be duplication at level 5 which needs to be examined before revisiting level 4 (David Connor)
