The resulting patchwork of complex micro-habitats and species present richness, biomass and productivity equivalent to tropical reefs. Hard to reach with classical diving methods, coralligenous concretions are poorly studied in comparison to their high ecological importance. RECOR is a monitoring network (Agence de l\u2019eau RMC \/ Androm\u00e8de oc\u00e9anologie) surveying coralligenous concretions at 120 stations along the French Mediterranean coast since 2010. We present here the first results concerning the totality of the 120 stations.<br \/>\nWe are interested in the link between anthropogenic pressures and species diversity distribution.<br \/>\n&nbsp;<\/p>\n<p style=\"text-align: center;\" align=\"center\"><b>Assessment on 90 years of coastal development in France.

Upper limits (0 to -15 m) of <i>P. oceanica<\/i> beds were mapped from historical (1920) and present aerial pictures. The comparison shows that upper limits are essentially stable (85 %) and regression (13 %) are mainly due to coastal artificialisation (65 %).<br \/>\n&nbsp;\t\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La semaine du 28 octobre 2013, Florian Holon et Julie Deter participeront au 40eme congr\u00e9s CIESM \u00e0 Marseille.
