Abstract
In this work the oil and detergent pollutions were investigated in sea water, near the refinery of TUPRAŞ and Ali Ağa, Istanbul Strait, Golden Hom and Çanakkale Strait. The pollutions were higher in refinery areas. The results inadequate that there is apparently no regular seasonal variation in oil and detergent amount. The maximum oil concentration in sea water was found 29.55 µg/L for Istanbul Strait 4214.29 µg/L for Golden Hom and 42.96 µg/L for Çanakkale Strait in 19.02.2005 and 90.02 µg/L for TUPRAŞ 3, 71.77 µg/Lfor Ali Ağa 2, in 07.Agust. 2006., in sediment 9573.38 µg/g for Istanbul Strait, 1126.45 µg/g for Golden Horn, 31.52 µg/g for Çanakkale Strait in 21.02.2005, 1500.6 µg/g for TUPRAŞ in 13.11.2006, 58.64 µg/g for Ali Ağa in 7.12.2006. These oillevels found are higher than the limit values for sea water and sediment. The LAS levels found are similar in earIier findings of this area.

Abstract
This paper, the Oligochaeta fauna of some lakes located at the West Black Sea Region of Turkey, was reported using results obtained. Having no previous faunistic studies, some physico-chernical features and Oligochaeta fauna of the lakes were determined for the first time in this research. Consequently, 30 species were determined, 13 species from Tubificidae family and 17 species from Naididae family. The average density of total Oligochaetes in the benthos of the lakes was 417 individuals m-2. The dominant species Tubifex tubifex accounted for 170 individuals m-2 and represented 40.7 % of total Oligochaeta community in the lakes studied. With regard to the rational distribution of species by station, Station 9 (Lake Yeniçağa) was the richest with 19.75% and Station 7 (Lake Abant) was the poorest with 3.23%. There are no data on the Oligochaeta fauna of this region so far. The determined taxa from is region.

Abstract
The seasonal changes in the histological profile of the ovary of Mytilus galloprovincialis Lamarck, 1819 were examined at light microscopic level and the alterations in the amount of total protein in the ovary were revealed by biochemical analyses. Samples were monthly collected from designated areas in Yenikapi shores of Sea of Marmara between June 2004 – May 2005. Although reproductive activities of Mytilus galloprovincialis populations in these areas decreased in some months, it has been observed that the reproduction activity has continued all the year round. The annual temperature alterations that have been measured were not much effective on the reproductive cycle.

Abstract
In this study the materials collected from the Northern coasts of Sea of Marmara between 1999- 2000 were evaluated and 33 species from 16 genera has been determined. Among these species Callistocythere diffusa, Loxoconcha littoralis and Loxoconcha pontica are new records for the Sea of Marmara. According to the Spermann analysis the primary hydrographical variables did not seem to be very effective in the distribution dynamics of the ostracod species in the Sea of Marmara. However according to the MDS analysis, it has been observed that Cyprideis torosa was affected by temperature, Xesteloberis communis by salinity, Loxoconcha rhomboidea and Paracytheridea parallia by dissolved oxygen when compared to other species.

Abstract
Two remarkable scientific events happened recently (Zaitsev, Polikarpov, Egorov et al., 2007, 2008) in the field of the newly developed deep-sea ecology and molismology of the hydrogen sulphide pelocontour in the Black Sea bathyal zone: discovery (in 2007) of viable spores of oxybionts in this aggressive zone against openly living oxybionts – those organisms which normally inhabit all three biocycles of the biosphere – the land, the fresh waters and the marine environment as well as Determination (in 2008) of the safe sojoum duration of the oxybionts’ spores by radioisotope dating in layers of the studied pelocontour sediment. Generalization and discussion of these events are presented.
