Ecological relevance of skeletal fatty acid concentration and composition in Mediterranean scleractinian corals

Abstract The intra-skeletal fatty acid concentration and composition of four Mediterranean coral species, namely Cladocora caespitosa, Balanophyllia europaea, Astroides calycularis and Leptopsammia pruvoti, were examined in young and old individuals living in three different locations of the Mediter...
