Erythrocyte Measurements Of Some Scincids From Turkey, Mehmet Kutsay Atatür, Hüseyi̇n Arikan, İ. Ethem Çevi̇k, Ahmet Mermer
Turkish Journal of Zoology
The aim of this study was to determine the erythrocyte and nucleus sizes of some scincids (Ablepharus chernovi, Chalcides ocellatus, Eumeces schneideri, Mabuya aurata, Mabuya vittata, and Ophiomorus punctatissimus) from Turkey by means of blood smears stained with Wright's stain. The largest erythrocytes were observed in the smears of E. schneideri, and the smallest in M. vittata, while the largest nuclei were observed in E. schneideri and the smallest were in M. aurata. In terms of the studied species, the nucleus and erythrocyte sizes were found to be correlated (r= 0.302, P< 0.01).

Age, Growth And Reproduction Of Acanthalburnus Microlepis, Filippi 1863 From The Yağan Region Of The Aras River, Turkey, Mustafa Türkmen, Orhan Erdoğan, H. İbrahi̇m Hali̇loğlu, Ayhan Yildirim
Turkish Journal of Zoology
The age, growth and reproduction characteristics of 1105 Acanthalburnus microlepis from the Yağan region of the Aras River, Turkey, were determined from monthly samples. Ages ranged from 1 to 7 years. The sex ratio was approximately 1.0 (51.49 % males, 48.51 % females). Females attained greater size and age than males. Von Bertalanffy growth parameters were: L_o= 29.87 cm, K= 0.1049, t_o= -1.92. The length-weight relationships for males and females were found to be W=0.0099L^{3.098} and W=0.0118L^{3.052} respectively. The condition coefficients of males and females were calculated as 1.192 and 1.209 respectively. Both sexes matured at the age of 2 …

New Localities Extend The Range Of Rana Bedriagae Caralitana Arıkan, 1988 (Anura: Ranidae) Further West And Suggest Specific Status, Tarek Jdeidi, C. Can Bi̇lgi̇n, Meral Kence
Turkish Journal of Zoology
Multivariate morphometric analyses revealed that the range of Rana bedriagae caralitana extends further west to include Çardak in Denizli (western Turkey). The presence of the forms caralitana and nominate bedriagae syntopically may indicate species status for the former.

Karyotype Of Eptesicus Serotinus (Schreber, 1774) In Turkey (Mammalia: Chiroptera), Nursel Aşan
Karyotype Of Eptesicus Serotinus (Schreber, 1774) In Turkey (Mammalia: Chiroptera), Nursel Aşan
Turkish Journal of Zoology
In order to investigate the conventional karyotype of Eptesicus serotinus (Schreber, 1774) in Turkey, four specimens were karyotyped. It was determined that the diploid number was 2n=50, the number of autosomal arms was FN=50, the X chromosome was large submetacentric, and the Y chromosome was dot-like acrocentric and the smallest chromosome of the set. All of the autosomes were acrocentric. A secondary constriction on a medium-sized acrocentric pair was encountered in most of the metaphase spreads examined.

Scanning Electron Microscopic (Sem) Observations On Some Members Of Actinosporean (Phylum Myxozoa) Collective Groups And Possible Usage Of Sem In Type Description, Ahmet Özer
Turkish Journal of Zoology
In this study, eleven different actinosporean types belonging to the collective groups synactinomyxon, aurantiactinomyxon, echinactinomyxon, raabeia and siedleckiella were observed under a scanning electron microscope (SEM) for the first time. The results obtained showed that surface structures and their ornamentation on the spore body and branches seen on the caudal processes of actinosporean spores are of importance in determination of the spores, at least at the collective group level.

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 Zoology
To establish a seed production technique for Black Sea turbot, Scophthalmus maximus, eggs and larvae were observed under artificial rearing conditions. Larvae were obtained artificially from eggs of tank-held broodstock. The egg fertilization was 27.6% and the fertilized eggs were 1.213±0.063 mm in diameter, were spherical pelagic and had one oil globule. From an initial length of 3.12±0.14 mm on day 0, the larvae grown to 167.28±15.32 mm in the normal group and to 159.98±12.25 mm in the abnormal group on day 246.

Stomach Contents Of The Catfish (Clarias Gariepinus Burchell, 1822) In The River Asi (Turkey), Şükran Özdi̇lek Yalçin, İhsan Akyurt, Kemal Solak
Turkish Journal of Zoology
Natural food items of catfish (Clarias gariepinus Burchell, 1822) were investigated in the River Asi from September 1996 to October 1998. Analyses of stomach contents showed that the catfish feed basically on Arthropoda, mostly Diptera larvae, and on plant materials to a considerable extent. A successful filter feeding was observed, especially during the summer period.
