Turkish Journal of Medical Sciences
Background: Although the pathogenesis of acute pancreatitis is not clearly known, the most frequently mentioned factors are proinflammatory cytokines and nitric oxide (NO), which is stimulated by bacterial endotoxins. The relationship of erythropoietin (EPO), which is an erythroid line growth hormone, with proinflammatory cytokines and NO is also not clear. EPO has a well-known general tissue protective effect, yet its role in an inflammatory presentation like that of acute pancreatitis has not been investigated and documented. Therefore, the aim of this study was to investigate the role of EPO in acute pancreatitis. Materials and Methods: 60 Wistar Albino rats were …

Turkish Journal of Zoology
In studies carried out from January 2001 to December 2002 in Ankara-Gölbaşı district, 9 mosquito species (Anopheles sacharovi, An. maculipennis, An. claviger, Culex mimeticus, Cx. pipiens, Cx. theileri, Culiseta annulata, Cs. longiareolata and Ochlerotatus caspius) were determined. The population estimations of immature stages were performed in 15 breeding habitats such as lake edge, swamp, wet pasture, canal and pond. The species that had the most sampled immature stages was Cx. pipiens (29.30%); An. sacharovi (18.93%) and An. maculipennis (17.47%) followed it. The samplings of adult mosquitoes were performed in 5 stables and 5 light traps. The most abundant species collected …

Turkish Journal of Zoology
The stomach contents of 986 pikeperch, Sander lucioperca (Linnaeus, 1758), collected from Lake Eğirdir in Turkey were investigated between March 2001 and February 2002. Thirteen taxonomic categories were identified from the 1745 prey items analysed. It was determined that the diet of pikeperch in Lake Eğirdir consisted of some fish species (Knipowitschia sp., Aphanius anatoliae anatoliae, Gambusia affinis, Nemacheilus lendli, Carassius gibelio, and Sander lucioperca), odonats (Calopteryx splendens), mysids (Mysis), amphipods (Gammarus) and dipterans (Chironomus). Of these prey categories, fish was more important than the others. In particular, Knipowitschia sp. and A. a. anatoliae were the primary prey for the …

Reproduction Properties Of Pike (Esox Lucius L., 1758) Population In Lake Karamık (Afyonkarahisar/Turkey), İsmet Balik, Hidir Çubuk, Remzi̇ye Özkök, Rahmi̇ Uysal
Turkish Journal of Zoology
In this study, the spawning period, length at first sexual maturity and fecundity of the pike (Esox lucius L., 1758) population in Lake Karamık between March 2002 and February 2003 were investigated. Mean length at first reproduction (L_m) was determined as 19.7 cm for female pike. The monthly values of the gonadosomatic index indicated that spawning occurred between February and March. The relative fecundity was determined as 45.7 ± 4.9 eggs g^{-1} total body weight. Fecundity (F) - fork length (L) and Fecundity - weight (W) relationships were estimated as F = 2.8963 L^{2.3722} (r = 0.590) and F = …
Prey Selection By African Catfish Clarias Gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes, Erdal Yilmaz, Ahmet Bozkurt, Kaya Gökçek
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.

On Specimens Of Darevskia Armeniaca (Sauria: Lacertidae: Darevskia) Collected From Ardahan, Çeti̇n Ilgaz
Turkish Journal of Zoology
Forty-seven Darevskia armeniaca specimens collected from 2 different localities in Ardahan were examined in terms of pholidosis characters, morphometric measurements and colour-pattern features. The 2 populations were differentiated from one another in terms of the number of supraciliar plates (left-right) (SCPa-SCPb), supralabial plates (left-right) (SRLa-SRLb) and transversal series of ventral plates (TVP) according to the results of the Mann-Whitney U test. An independent t-test based on morphometric measurements revealed significant differences in terms of the head index (HI) between the 2 populations. Regarding pholidosis characters, morphometric measurements and colour-pattern features, specimens collected from the 2 localities showed a similarity to …

Growth And Reproduction Of Por's Goatfish (Upeneus Pori Ben-Tuvia & Golani, 1989) In İskenderun Bay, The Eastern Mediterranean, Ali̇ İşmen
Turkish Journal of Zoology
The age composition, growth parameters, spawning season, sex ratio, length at first sexual maturity and fecundity of por's goatfish (Upeneus pori) caught from the Bay of İskenderun in the eastern Mediterranean Sea were investigated. Females and males made up 52.6% and 47.4%, respectively, of the particular population of the species. The total length of females ranged from 7.0 cm to 17.0 cm, and of males from 6.6 cm to 15.1 cm. The length (L) - weight (W) relationships for males and females were estimated as W = 0.0108*L^{2.99} and W = 0.0097*L^{3.03}, respectively. The age data derived from otolith readings …

Turkish Journal of Zoology
Samples were collected from 7 different stations between January 2002 and December 2002 with a view to identifying the littoral benthic fauna (Oligochaeta and Chironomidae) of Lake Kovada, located in Southern Anatolia. As a result of this study, 35 species were determined, comprising 15 species from Oligochaeta (8 Naidid and 7 Tubificid), and 20 species from Chironomidae (4 Tanypodin, 2 Orthocladiin, 12 Chironomini and 2 Tanytarsin). Species richness varied between 11 and 19.

The Oligochaeta (Annelida) Fauna Of Topçam Dam-Lake (Aydın, Turkey), Seray Yildiz, Süleyman Balik
Turkish Journal of Zoology
With the aim of identifying the oligochaeta fauna of Topçam Dam-Lake, located on the north-western slopes of the East Menteşe Mountains (Aegean region, Turkey), a number of samples were collected monthly between June 1999 and June 2000. Having no previous faunistic studies, some physico-chemical features and oligochaeta fauna of the dam-lake were determined for the first time in this research. Consequently, 11 species were determined, 9 species from Tubificidae, and 2 species from Naididae. Tubificid Limnodrilus hoffmeisteri was the dominant Oligochaeta species and represented 64.64% of the total Oligochaeta community in the dam-lake. There are almost no data on the …

Contribution To The Taxonomical And Biological Characteristics Of Sciurus Anomalus In Turkey (Mammalia: Rodentia), İrfan Albayrak, Ati̇lla Arslan
Turkish Journal of Zoology
This study is based on 62 Sciurus anomalus specimens obtained from Konya, Karaman, Kütahya and Çorum provinces between 1997 and 2002. Some ecological and biological features of the species, including habitat, nest-sites, fur colour, baculum and phallus were investigated. In this species, the chromosome number (2n) is 40. For the taxonomical evaluation of Sciurus anomalus, morphometric data of the specimens were used. The specimens were discussed at the subspecies level, comparing to the relevant literature, and it was concluded that our specimens represent the nominate form.

Carapacial Scute Variation In Green Turtle, Chelonia Mydas Hatchlings In Northern Cyprus, Burcu Özdemi̇r, Oğuz Türkozan
Turkish Journal of Zoology
The carapacial scutes of 718 green turtle hatchlings, Chelonia mydas (Linnaeus, 1758), from 2 different nesting beaches in Northern Cyprus were examined. Scutes were examined with regard to variation within carapacial scute series and variation in carapacial scute pattern. The vertebral, costal and marginal series were the most variable and the supracaudal scutes were almost stable for the hatchlings. The most common scute pattern observed was 11 pairs of marginals, 4 pairs of costals, 5 vertebrals, 2 supracaudals and a single nuchal. The straight carapace length (SCL) of the hatchlings ranged from 39 to 51 mm with a weight that …
