This study was carried out to determine anomura species in Edremit Bay and some of their ecological properties. The samples were collected from 31 stations between 2001 and 2003, from depths of 0.5-60 m, by using scoop net, dredge, beam-trawl and trammel net. A total of 19 anomura species belonging to 4 families were identified during the course of this study. One of these [Galathea strigosa (Linnaeus,1767)] was first reported from the Turkish territorial waters of the Aegean Sea. Primary hydrographic conditions, such as temperature (13.0-29.0 oC), salinity (35.9-38.9 ‰) and dissolved oxygen (2.76-9.82 mg l-1) were recorded on each sampling occasion.

The antibacterial materials such as fabrics, cloths are became important to avoid cross infection by pathogenic microorganisms, especially bacteria such as Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae, to control the infestation by microbes, and to arrest metabolism in microbes in order to reduce the formation odour. Textiles for medical and hygienic use have become important areas in the textile industry. Therefore, to reduce/prevent infections, various antibacterial compounds have been used for all types of textiles. The solutions of disinfectant used are generally active in vitro, but, it is also necessary to know the effectiveness of disinfecting cloths in conditions of use. In the current study, it was aimed to determine the antibacterial activity of fabrics functionalized with dimethlytetradecyl (3-(trimethoxysilyl) ammonium chloride compound against Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae bacteria, and also after 5, 10 and 20 wash cycles against Staphylococcus aureus. The results of the present study showed that the most susceptible bacterium was S. aureus in all standard test methods for unwashed fabrics, antibacterial activity was continued by decreasing even after washing cycles.

Planktoniella sol is reported for the first time from Turkish coasts. The specimen was collected on 6 June 2001 with a 55 μm plankton net from subsurface (0.5 m) neritic waters with a depth of 30 m, off Bozcaada Island in the Aegean Sea. The primary hydrographic parameters, temperature, salinity and dissolved oxygen were 18.5 oC, 35.2 psu and 8.54 mg l -1 , respectively. A brief diagnosis based on morphological characters are described in detail and information about its ecological distribution is given.

Earthworms are able to protect themselves against invading microorganisms through their immune systems. Although there are many studies about defense systems of Dendrobaena veneta , this is the first report focusing on the immune properties of earthworms belonging to the same species, which live in different localities. Thus, it was aimed to compare antibacterial and hemolytic activities of earthworms collected from different localities of Istanbul (Vezneciler, Suleymaniye and Beykoz). Both activities were studied with dilution and agar diffusion techniques. In antibacterial activity assays with dilution technique, it was observed that all suspensions of coelomic fluid of D. veneta living in Beykoz had significantly strong activity, while no results could be determined in diffusion assays. Nevertheless, in dilution assays for determination of hemolytic activity, coelomic fluid of earthworms living in Suleymaniye was the most effective group. In dilution assays, hemolytic activity were in the order of (S) > (V) > (B) for human erythrocytes. As a conclusion, coelomic fluid of Beykoz earthworms was a potential agent, which can be used as an alternative drug, since this coelomic fluid was effective against bacteria but not on erythrocytes.

Buyukcekmece Lake is a lagoon lake located at the mouth of Karasu Stream, which drains into the Sea of Marmara. The sea connection of the lagoon was blocked by the Buyukcekmece Dam in 1985 so the lagoon became a freshwater lake over time. Non–native Carassius gibelio (Bloch 1782) was introduced to the lake by a fisherman in early 1990s. By the time, it has become one of the most dominant fish species in the lake despite predators like Esox lucius , Linneaeus 1758, Silurus glanis Linnaeus, 1758 and also other cyprinids such as Cyprinus carpio , Linneaeus 1758, Scardinius erythrophthalmus (Linneaeus 1758) which have similar feeding regime. The aim of the current study was to study the growth and reproduction characteristics of gibel carp living in the lake. Field surveys were carried out monthly between March 2009 and April 2010. Fork length and body weight were determined between 4.4–31.4 cm and 1.44–774.4 g, respectively. The female:male ratio of total 487 gibel carp specimens was estimated as 20.1:1.0. The age composition of the population ranged from age class I to XI. The length–weight relationships, condition factor and von Bertalanffy growth parameters were estimated for all individuals as W =0.0154 FL 3.134 , K=2.26 (SE=0.02) and L t =33.97[1–e -0.198(t+0.162) ], respectively. Length at first maturity was calculated as 13.23 cm FL for females. Mean absolute fecundity in a mature female was 46,628 eggs (SE = 3,880), ranging from 5,266 eggs (16.7 cm FL) to 78,416 eggs (25.3 cm FL). The relationships between fecundity and fish size (fork length and weight) were calculated by regression analysis and the fecundity increased exponentially with the fish length and weight.
