    (Ege Univ, 2005) Kirkim, Fevzi; Sezgin, Murat; Katagan, Tuncer; Kocatas, Ahmet; Ates, A. Suat
    This study focused on Crustacea fauna of rocky communities of Turkish Aegean Sea coasts. Samplings were carried out a total of 20 stations was chosen from the upperinfralittoral zone located between the northern toward southern in July and June 1995-1996. A total of 119 species and 3785 specimens belonging to crustacea were recorded. In the study area, Sphaeroma serratum was the highest dominance value with up to 400 specimens (% 10.57), followed by Pisidia bluteli with 319 specimens (% 8.43), Ampithoe ramondi with 279 specimens (% 7.29) and Maera hamigera with 158 specimens. Among the species identified, Maera hamigera ve Stenothoe gallensis are lessepsian species.

    (Walter De Gruyter Gmbh, 2012) Ates, A. Suat; Sezgin, Murat; Katagan, Tuncer; Ozdilek, H. Goksel; Berber, Selcuk; Kolsal, Secil; Bircan, Cuneyt
    The structure of the benthic amphipod assemblage and its relationship with soft-bottom characteristics (particle size, organic matter, etc.) of the coastal waters at the depths of 0-5 m at the Dardanelles, including the Turkish Straits System, was studied. A SCUBA diver took benthos and sediment samples seasonally using a quadrate system of 30x30 cm as three transects from the 8 different stations between July 2008 and April 2009. A total of 3007 individuals belonging to 50 species was reported. Among these, Corophium acutum Chevreux, 1908 had the highest dominance value (Di%=22.18) and the lowest dominance value belonged to Dexamine thea Boeck, 1861 (Di%=0.03). The highest positive correlation (r(s)=0.57, p < 0.05) was observed between the gravel content (%) and the abundance (ind. m(-2)). The highest sand rate (99.59%) in the sediment was found at the Eceabat site. The lowest rate was at the Kepez Harbour station with a value of 73.01%. The highest H' value (1.53) was recorded at the Eceabat site, and the lowest H' value (H'=0.95) was recorded at the Gallipoli sampling station.
