The Morphology, Taxonomy, And Distribution Of Specimens Of Darevskia Clarkorum (Sauria: Lacertidae: Darevskia) Collected From Turkey’S Eastern Black Sea Region, Çeti̇n Ilgaz
Turkish Journal of Zoology
In all, 103 specimens of Clark's lizard, Darevskia clarkorum (Darevsky and Vedmederja, 1977), from 6 localities in the eastern Black Sea region of Turkey were examined in terms of pholidosis characteristics, morphometric measurements, and color and pattern features. Kolmogorov-Smirnov testing across all populations verified sexual dimorphism in the Ortacalar and Hemşin populations, regarding transversal series of ventral plates (P < 0.05). According to the Mann-Whitney U test, 16 pholidosis characteristics showed differences among the populations (P < 0.05). For comparison of morphometric measurements, 4 morphometric indices and ratios were developed. According to the results of independent t-testing, no differences were found between males and females among the populations. One-way variance analyses based on 4 morphometric indices and ratios confirmed that head index, snout-vent length/tail length, and tail length/total body length showed differences among the populations (P < 0.05). Regarding pholidosis characteristics (except rates of the presence of a masseteric plate and contact between the rostral and internasal plate), morphometric measurements, and color and pattern features, the specimens collected from 6 different localities were similar to D. clarkorum specimens mentioned in the literature. Furthermore, the known range of the species in Turkey has been extended.

Life Cycle Of Gammarus Pulex (L.) In The River Yeşilırmak, Mustafa Duran
Life Cycle Of Gammarus Pulex (L.) In The River Yeşilırmak, Mustafa Duran
Turkish Journal of Zoology
Monthly sampling of Gammarus pulex for 45 months in the River Yeşilırmak showed that the mean seasonal population density increased to a maximum in summer, and then declined to the lowest level in winter. There was a consistent seasonal pattern of body length distributions, characterised by the arrival of a strong cohort of new juveniles in spring and early summer. The ovigerous adults were few in autumn, peaked around January to March, and were virtually absent from July to October. Estimated sex ratios obtained from the field in general seem to show that females predominated, except in summer.

A Serological Investigation Of Pelodytes Caucasicus And Pelobates Syriacus (Amphibia, Anura) Populations In Turkey, Murat Tosunoğlu, Hüseyi̇n Arikan
Turkish Journal of Zoology
Blood serum proteins of specimens belonging to Pelodytes caucasicus and Pelobates syriacus populations were compared qualitatively and quantitively by means of polyacrylamide disc electrophoresis and densitometry methods. It was determined that the blood serum proteins of both populations demonstrated qualitative and quantitive differences. This result supports the morphological and osteological studies emphasizing the fact that the genus Pelodytes needs to be treated as a separate family (Pelodytidae).

Prey Selection By African Catfish Clarias Gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes, Erdal Yilmaz, Ahmet Bozkurt, Kaya Gökçek
Turkish Journal of Zoology
Live prey selection by African catfish, Clarias gariepinus, larvae was examined under laboratory conditions. Larvae were offered plankton, plankton + trout starter (TS) and plankton + betaine supplemented trout diet (BTS) for 7 days after exogenous feeding. Five larvae were sampled to determine their gut contents and selectivity index for each treatment 15 min after the feeding. It was observed that dry diets (TS and BTS) improved the growth (P < 0.05), but did not significantly influence the prey selection of the larvae. It was determined that African catfish larvae preferred Copepods and Rotaria sp. to other zooplankton species for all feeding regimes.
