Histological Investigation Of Gonad Development Of Chalcalburnus Tarichi (P., 1811), Güler Ünal, Osman Çeti̇nkaya, Mahmut Elp
Turkish Journal of Zoology
In this study, gonad development of Chalcalburnus tarichi, an anadromus, endemic fish species of the Lake Van and its inlets was histologically investigated. During oogenesis, six different development phases were histologically identified: chromatin-nucleolus, perinuclear, cortical alveolar, vitellogenic, ripening and ovulation phases. The diameters of oocytes were determined between 31 to 957 µm until the ovulation phase. According to the investigated sepcimens, vitellogenic phase started onward October and first ovulation was taken place in May-June 36 months and older females. It was found that some unspawned ova remained and formed atretic follicles in ovary after ovulation. Three different development phases were …

A Study On The Activities Of Glucose-6-Phosphate Dehydrogenase And 6-Phosphogluconate Dehydrogenase Enzymes In Some Spalax Populations, H. Ramazan Yilmaz, Eşref Yüksel
Turkish Journal of Zoology
The purpose in planing this investigation was to contribute to the speciation problems in genus Spalax. For this, we examined the activities of Glucose-6-Phosphate Dehydrogenase (G-6-PD) and 6-Phosphogluconate Dehydrogenase (6-PGD) enzymes from the liver of Spalax samples taken from both sides of river Euphrates. The samples belonging to genus Spalax were separated into two populationsin the research area. The spesific activities of G-6-PD and 6-PGD enzymes were measured at 0.01 level of significance. The results were given in a table. The observed differences between the mean specific activities of te enzymes of the two populatons were discussed.

Growth And Mortality Of Mussels ( Mytilus Edulisl.) Reared Inlantern Nets In Loch Kishorn, Scotland, Sedat Karayücel, Ismi̇han Karayücel
Turkish Journal of Veterinary & Animal Sciences
One-year old rope grown mussels ( Mytilus edulis L.) were held in experimental lantern nets at 2 m and 6 m depths in Loch Kishorn on the west coast of Scotland. Growth, mortality and shell morphology were monitored from May 1993 to August 1994. Water temperature, salinity, transparency and food availability were also determined. These showed a clear seasonal cycle, in consequence, growth of mussels was relatively rapid from May to November and very slow during the rest of the year. Depth had a insignificant effect on shell length and tissue growth (P>0.05) due to similar environmental factors. Shell …

Problem Identification And Priority Setting In Agricultural Research: The Case Of The Eastern Margin Of Central Anatolia, Vedat Uzunlu, Ahmet Bayaner, Surendra P. S. Beniwal
Turkish Journal of Agriculture and Forestry
Since the resources available to research institutes are scarce, and experimentation is the most costly phase of a research program, researchers must make sure that the possible solutions to identified problems have a high chance of success. Consequently, problems should be carefully prioritized for experimentation. Factors limiting increased productivity in crop production in the Eastern Margin of Central Anatolia (EMCA) along with agro-ecological factors, apart from political concern, are agronomic constraints. Limiting factors in livestock production are insufficient feed supply, poor conditions of natural grazing areas, and housing of animals. Increasing the adoption rate of the recommended production practices among …

The length and the angle of the mandibles were measured and the correlation was determined between the female and male dogs. Mandible measurements increased with the age of the animals. In males, the value of the 1A and 2A angle was not statistically significant when considering age. In females, a decrease in the 1A and 5A angles was determined while no statistically significant value was determined in 2A, 3A and 4A with age. In conclusion, morphological observations and the results of the measurements have shown that German …

The cells at the tip of the roots of germinated seeds of Vicia galileae were caryologycally examined and the chromosome number was found to be 2n=14. The strach grains were observed in the epidermis, endothecium and middle layer cells in the early development phases of the anther walls. Normal mitotic divisions were observed in the glandular type tapetum. Also it was observed that meiotic divisions in most of the microspore mother cells were regular and irregularities were only 1- 2%. Polarization which occurred normally in pollen mitosis and the divison stages were clearly observed. It was noted that pollens were …
