A PRELIMINARY BIODIVERSITY SURVEY IN THREE SHIPWRECKS IN THE DARDANELLES (MARMARA SEA, TURKEY)

In this study macro aquatic biota inhabiting on three different shipwrecks in the canakkale Strait were investigated during the winter of 2010-2011 and the summer of 2014-2015 (Nov. 2010 -Sep 2015). One of the shipwrecks is strongly dominated by gorgonian corals while others had only a variety of algae and fish; 5 anthozoans, 2 echinoderm, 1 tunicate, 33 fish and 31 macroalgae species were determined. Visual census techniques were used for evaluation of fish assemblages around the sites. Based on faunal characteristics, the shipwrecks could be classified as three different groups

A NEW RECORD FOR THE MARINE ALGAL FLORA OF TURKEY: TITANODERMA TROCHANTER (BORY DE SAINT-VINCENT) BENHISSOUNE, BOUDOURESQUE, PERRET-BOUDOURESQUE AND VERLAQUE, 2002 (RHODOPHYTA, CORALLINALES, CORALLINACEAE)

The coralline alga, Titanoderma trochanter, was recorded for the first time in Turkey. In 2009, thalli were observed in the wave-exposed lower eulittoral rock settings at depths of 0.1-0.5 m on the coasts of Fethiye Bay (south-eastern Aegean Sea) and Kas (Antalya, Levantine Sea). It often covered approximately 30-40% of rocky substrata where it was found in Fethiye Bay. The vegetative structure as well as habitat and the distribution of this species are described
