The Evaluation Of Alkalitolerant-Mesophilic Streptomyces By Gas Chromatography And Pyrolysis Mass Spectrometry, Nevzat Şahi̇n, Kami̇l Işik, Ergi̇n Kari̇ptaş, Michael Goodfellow
The Evaluation Of Alkalitolerant-Mesophilic Streptomyces By Gas Chromatography And Pyrolysis Mass Spectrometry, Nevzat Şahi̇n, Kami̇l Işik, Ergi̇n Kari̇ptaş, Michael Goodfellow
Turkish Journal of Biology
Thirty-eight alkalitolerant-mesophilic Streptomyces, defined by Saddler in his numerical taxonomic study, were evaluated by gas chromotography and pyrolysis mass spectrometry. Group I Streptomyces sp. AK409 and group II Streptomyces sp. AK029 selected duplicated strains were clustered in their own groups. It was observed that the results of gas chromatography and pyrolysis mass spectrometry was in good congruance with the numerical taxonomic results. Therefore, it can be concluded that the different chemotaxonomic methods provide rapid and reproducible information for classifying biotechnologically significant Streptomyces strains.

This study was carried out to determine the species of the subfamily Agathidinae (Hymenoptera: Braconidae) in the Marmara region of Turkey. Samples were collected from 47 localities between 1985 and 1997. A total of 16 species were determined. The results revealed that Agathis fulmeki Fischer and Bassus linguarius (Nees von Esenbeck) are new records for the Turkish fauna.

Some Biological Characteristics Of Silurus Triostegus Heckel, 1843 From Atatürk Dam Lake (Turkey), Seyi̇t Ahmet Oymak, Kemal Solak, Erhan Ünlü
Turkish Journal of Zoology
In this study, some biological characteristics such as age and sex composition, growth in length and weight, age-length, age-weight and length-weight relationships, condition factor spawning time, age of sexual maturity, and fecundity of Silurus triostegus in Atatürk Dam lake were investigated. The percentage of females was 48.3% and that of males 57.7% out of 623 specimens belonging to age groups I-XI. Isometric growth patterns were proved from the length-weight relationships. It was estimated that the females had higher Lo (202.85 cm) and lower low K (0.046871) values than males (Lo 113.98 cm and K = 0.101972). Mean condition factors of …
A Study On The Feeding Biology Of Laudakia (=Agama) Stellio (L. 1758) (Lacertilia: Agamidae) Populations In The Antalya Region, Serdar Düşen, Mehmet Öz
A Study On The Feeding Biology Of Laudakia (=Agama) Stellio (L. 1758) (Lacertilia: Agamidae) Populations In The Antalya Region, Serdar Düşen, Mehmet Öz
Turkish Journal of Zoology
The feeding biology of Laudakia (=Agama) stellio (L. 1758) was studied using 91 specimens collected from the Antalya region over two consecutive years (1995 and 1996). A total of 1224 prey items were identifed and their frequency of occurrence and percent of diet were tabulated. The majority of the diet consisted of the class Insecta (99.18%), and within this class, Hymenoptera (72.21%) was the major order represented, primarily by the families Formicidae (49.83%) and Apidae (16.74%). In addition to insects, L. stellio feeds on plant material, insect larvae and eggs, and even snails, showing opportunist feeding behavior.

The Effects Of Cold Storage On The Adult Longevity, Fecundity And Sex Ratio Of Apanteles Galleriae Wilkinson (Hym.: Braconidae), Fevzi̇ Uçkan, Adem Gülel
Turkish Journal of Zoology
The effect of cold storage on the adult longevity, fecundity and sex ratio of Apanteles galleriae Wilkinson, a koinobiont, solitary and early instar larval endoparasitoid of the Small Wax Moth Achoria grisella Fabr. was investigated. The rearing of both parasitoid and host cultures and experiments related to the effect of storing Apanteles galleriae adults at low temperature (+ 6°C) were conducted at 25 ± 1°C, 60 ± 5% RH under a photoperiod of 12:12 (L:D). Cold storage (+ 6°C) considerably influenced the adult longevity, fecundity and sex ratio of the parasitoid. Experimental evidence showed that 85.27% of adults died after …
Certain Reproductive Characteristics Of The Catfish (Clarias Gariepinus Burchell, 1822) Living In The River Asi, Turkey, Şükran Özdi̇lek Yalçin, Kemal Solak, İhsan Akyurt
Certain Reproductive Characteristics Of The Catfish (Clarias Gariepinus Burchell, 1822) Living In The River Asi, Turkey, Şükran Özdi̇lek Yalçin, Kemal Solak, İhsan Akyurt
Turkish Journal of Zoology
A total of 523 C. gariepinus caught in the River Asi were surveyed from October, 1996 to September, 1998 to find out the age distribution throughout the population that varied between 0+ and 5 years of age, with the one year age group observed to be dominant in number. Findings also showed that both sexes started to reach maturity at the age of 1, and all the fishes examined had become mature by the end of the second year. The average diameter of ripened eggs was 1.41 - 1.66 mm. They spawned in a period from May to August when …
Comparable Age Determination In Different Bony Structures Of Pleuronectes Flesus Luscus Pallas, 1811 Inhabiting The Black Sea, Nazmi̇ Polat, Derya Bostanci, Savaş Yilmaz
Comparable Age Determination In Different Bony Structures Of Pleuronectes Flesus Luscus Pallas, 1811 Inhabiting The Black Sea, Nazmi̇ Polat, Derya Bostanci, Savaş Yilmaz
Turkish Journal of Zoology
The aim of this study is to determine the most reliable bony structure for ageing of Pleuronectes flesus luscus inhabiting the Black Sea. The age determination method and its accuracy are the most important subjects for the evaluation of age-weight-length relationships in fisheries biology, since the estimates of survival, growth and mortality rates, and the analysis of year classes and recruitment all depend on age structure. In this study, scales, vertebrae and otoliths removed from each fish were examined by two readers three times each without reference to any data except the date of capture. The precision of readers and …

Turkish Journal of Veterinary & Animal Sciences
In this study,808 vimba (Vimba vimba tenella(Nordmann,1840))individuals captured during October 1996-April 1998 from Karacaören I Dam Lake and some properties of reproduction were investigated. In the vimba population,age composition varied from 0-VII and 73.51% of the investigated samples belonged to I-II age group. The population was composed of 50.74% females and 49.26% males. It was determined that the reproductive activity of the vimba in the Karacaören I Dam Lake started in the middle of April and continued until the end of June. Sexual maturity ages were found to be II-III for females and II for males. Average egg numbers belonging …

Relationship Between Psychopathology And Regional Cerebral Blood Flow Detected By Tc-99m Hmpao Spect In Patients With Predominantly Positive Or Negative Schizophrenic Symptoms, Nazan Aydin, Erhan Varoğlu, Mehmet Dumlu Aydin, Hati̇ce Uslu, Ali̇ Çayköylü
Turkish Journal of Medical Sciences
We investigated whether rCBF values obtained with the SPECT technique are different in schizophrenics with predominantly positive or negative symptoms and assessed the biological underpinnings of psychotic phenomena, which has been done repeatedly in the past, with somewhat varied results. Twenty-nine schizophrenic patients were examined to investigate the relationship between regional cerebral blood flow (rCBF) and psychopathology according to SANS, SAPS and BPRS scores. Using the Tc-99m HMPAO SPECT method at rest, rCBF was assessed in 15 patients with predominantly positive (group I) and 14 with predominantly negative (group II) symptoms. Ten age-matched normal healthy volunteers comprised the control group. …
