The structure of sessile epibiotic assemblages fouling the shells of farmed populations of the common Mediterranean mussel Mytilus galloprovincialis, a species known to be involved in ecosystem engineering processes, was investigated in the north Aegean Sea. Mussel samples were collected from three aquaculture installations and all sessile organism...
Article
Biometric variables of Actinia equina mediterranea Form 1 were correlated with one another to identify those that are independent of size, and could therefore be used for taxonomic purposes. The length, surface area, and volume of the cnidae are correlated significantly with individual weight of the anemones. The ratios length/width and surface are...
Article
In an attempt to combine the recent interest in the study of the polychaete feeding modes and the importance of the unique Mediterranean scleractinian species Cladocora caespitosa, we examined the feeding guilds of polychaetes associated with this coral. Nine feeding guilds were identified among 87 polychaete species living in association with Clad...
Article
Actinia equina L. is a ubiquitous species of sea anemone in the North Aegean Sea. The large variation in coloration in this species is problematic for taxonomists and ecologists. Considerable variation exists within the cnidae of the red morph of A. equina mediterranea sensu Schmidt, 1972, but not within the green morph. The two color morphs of A....
