Relationships of benthic amphipod communities with environmental variables in the shallow waters of the Dardanelles

Abstract

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 30×30 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 * Corresponding author: asuatates@yahoo.com (Di%=0.03). The highest positive correlation (rs=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 Hˊ value (1.53) was recorded at the Eceabat site, and the lowest Hˊ value (Hˊ=0.95) was recorded at the Gallipoli sampling station.

Feeding habits and diet overlap of juveniles of 2 sparids, Diplodus puntazzo(Walbaum, 1792) and Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817), from theNorth Aegean Sea of Turkey

“…Copepods were the most important prey items for D. puntazzo in autumn, while Amphipoda was dominant in summer. Ateş et al (2012) recorded 50 Amphipoda species in shallow water (0-5 m) in the Çanakkale Strait. In addition, a total of 110 peracarid species were identified and amphipods were the dominant group both in terms of species richness and abundance in the Çanakkale Strait.…”
