Abstract

In this research, marine algae and seagrasses were investigated in the upper infralittoral zone of Mersin (Turkish Mediterranean coasts). A total of 396 algae and 5 seagrasses were determined. 36 of them belong to blue-green algae (Cyanophyceae), 204 to red algae [Rhodellophyceae (2), Compsopogonophyceae (2), Bangiophyceae (6), Florideophyceae(I94)], 82 to brown algae (Fucophyceae), 74 to green algae [Chlorophyceae (7), Ulvophyceae (19), Trentepohliophyceae (1), Cladophorophyceae (25), Bryopsidophyceae (20), Dasycladophyceae (2)] and 5 to seagrasses (Liliopsida).

Abstract

Surface water taken from 12 different areas in the period from July 2002 to June 2003 from Sapanca Lake, (Sakarya, Turkey) was analyzed in order to detect levels of bacterial contamination, bacterial metabolic activity, and chemical content. Level of bacteria was examined with respect to Fecal coliform, Escherichia coli and Salmonella spp. The contribution of capsule-bearing bacteria to the total number of bacterioplankton community was enumerated in order to assume the metabolically active number of bacteria. Levels of dissolved oxygen, nitrate, nitrite, orthophosphate, total hardness and calcium were calculated. Bacterial counts were made using Membrane Filtration Technique. Capsulated and non-capsulated bacteria were determined using a modified negative staining technique. As a result, the highest level of F. coliform found was 24×10³MPN/ 100 ml in the surface water samples, which were taken from the western side of the Lake. While Salmonella spp. was found to be positive, contribution of capsulated bacteria to the total bacteria was found to be higher (19.6 %) in the same region. Results of this study have shown that level of indicator bacteria and percentage of potentially active bacteria are higher in samples of surface water collected from western part of the Sapanca Lake. Evaluation of the relations between surface fecal coliform and other environmental factors showed that the western region of the Lake was exposed to sewage wastes.

Abstract

Two fish species (Apletodon dentatus bacescui and Coryphoblennius galerita) were collected from Sinop coasts, which were previously not recorded from the central Black Sea coasts of Turkey. Morphometric and meristic characteristics of the species are presented.

Abstract

Marine algae and seagrasses were researched in the upper infralittoral zone of Adana (Turkish Mediterranean coasts) in this study. 381 algae and 5 seagrasses (Liliopsida) were determined (Total 386 taxa). 27 of them belong to blue-green algae (Cyanophyceae), 204 to red algae [Rhodellophyceae (2), Compsopogonophyceae (2), Bangiophyceae (5), Florideophyceae(195)], 78 to brown algae (Fucophyceae), 72 to green algae [Chlorophyceae (7), Ulvophyceae (18), Trentepohliophyceae (1), Cladophorophyceae (22) Bryopsidophyceae (22), Dasycladophyceae (2)]. Ceramium siliquosum (Kützing) Maggs & Hommersend var. zostericola f. zostericola, C. tenuicorne (Kützing) Waern (Rhodophyceae), Bryopsis adriatica (J. Agardh) Meneghini (Bryopsidophyceae) are given as newly record for the Mediterranean shores of Turkey.

Abstract

The aim of this study was to determine the ostracoda fauna of the South of Marmara Sea. The results were compared with the similar species from the surrounding seas. The Materials were obtained from 27 areas between 11 March-26 July 2000. 35 species were determined of which 12 were dominant. The findings showed that South of Marmara Sea generally contained cosmopolitan species, that were tolerant to salinity. Also total individual number of species in the South of Marmara Sea appeared to be positively correlated to dissolved oxygen (r_s=0,409, p<0,05) rather than other ecological variables and temperature negatively correlated to dissolved oxygen (r_s=-0,771, p<0,05).
