This paper presents the results of a preliminary survey of the spiders of Marmara region and provides new data on the spider fauna of Türkiye. During the study, spider samples were collected by hand aspirator and pitfall traps. As a result, Heliophanus apiatus Simon, 1868 (Salticidae) is recorded for the first time from Türkiye. Also, occurrence of Amaurobius pallidus L. Koch, 1868 (Amaurobiidae) is confirmed with this study. Additionally, the record of H. apiatus from Marmara region represents the easternmost point of its distribution range. A morphological diagnosis, comparative pictures, and illustrations are provided for both species. [ABSTRACT FROM AUTHOR]

The aim of this study was to determine bacterial, parasitological and viral agents of diarrhea in lamb and goat kid in Marmara Region of Turkey. The material of this study was consisted of 88 lambs and 26 kids which were younger than 6 months old. A total of 26 Escherchia coli (22.8%), 27 Eimeria spp. (23.7%), 11 Cryptosporidium spp. (9.6%) and 6 Clostridium perfringens (5.3%) were identified from samples. In addition Rotavirus and Pestivirus were detected in 3, 4 of 114 of samples respectively. It was concluded that determining the most common agents that cause diarrhea in young small ruminants in Marmara Region may contribute to therapeutic approaches and prophylactic medicine procedures.

The seismic anisotropy contains information regarding the fabrics and deformation of deeper parts of the earth (Babuska etal., 1998). In an anisotropic medium, one component of a shear wave travels faster than the orthogonal component. The difference in speed causes the waves to separate; this phenomenon is called shear wave splitting (Savage, 1999).SKS splitting analysis is one of the most widely used methods to determine anisotropy (Silver and Chan, 1991). SKS splitting parameters; fast polarization direction (φ) and delay time (δt), provide information about the dominant flow direction and thicknessof the anisotropic layer. The study of anisotropy can shed light to the complex tectonic structure (or strain pattern) of the area when evaluated together with whole tectonic and GPS data. In the areas of recent convergence the fast direction of anisotropy generally aligns in the direction of the plate boundary (Vinnik etal., 1992). This correlation suggests that the shortening is the same in the crust and the upper-mantle. In the regions of rifting, direction of mantle flow generally aligns parallel to the extension in the crust. In the stable regions it is likely that combined effect of frozen anisotropy in the lithosphere and recent anisotropy in the asthenosphereare observed.The tectonic regime of Turkey is dominated by different plate motions. The collision of Eurasia and Arabia in the Zagros region is the driving force of west-ward tectonic escape towards the Aegean between a rigid boundary on the north, oceanic crust in the Black Sea and a weak boundary on the south, Aegean subduction zone (Şengör etal., 1985). The escape is mainly along the North and East Anatolian strike-slip faults. The fast shear wave polarization direction obtained from SKS splitting studies can be correlated with the absolute motion of the plates and the study of anisotropy can light up the complex tectonicstructure (or strain pattern) of the area. In this study, seismic anisotropic structure of the upper-mantle beneath İstanbul (ISK) broad-band station (KRDAE-NEMC), Marmara Region, is investigated by using SKS splitting analysis. Fifteen earthquakes with magnitude greater than 5.0 occurred at epicentral distances between the range of 85° and 120° are selected based on the criteria of existing of clear SKS phases on the records. Splitting correction method of Silver and Chan (1991) can be used for obtaining SKS splitting parameters (φ, δt). In this method, analysis window is chosen manually. But calculated parameters are sensitive to the manually selected shear-wave analysis window. Therefore, we used an automated shear wave analysis code (Teanby etal., 2004) to analyse the data. In this code, the analyse window is selected automatically by performing a grid search over different windows to find stable splitting measurements with small error. … [ABSTRACT FROM AUTHOR]
