Bayesian Analysis Of Test Day Milk Yields In An Unbalanced Mixed Model Assuming Random Herd-Year-Month Effects, Mehmet Zi̇ya Firat
Bayesian Analysis Of Test Day Milk Yields In An Unbalanced Mixed Model Assuming Random Herd-Year-Month Effects, Mehmet Zi̇ya Firat
Turkish Journal of Veterinary & Animal Sciences
The main environmental effects in a mixed model are comparison or contemporary group effects or more precisely herd-year-month of calving subclass effects. The controversial subject of much discussion about the choice between treating contemporary group effects as fixed or as random has not still been settled in dairy cow evaluation. However, these effects are usually treated as fixed since nonrandom associations between sires and herds may lead to biased predictions if herd-year-month effects are accounted for as random. On the other hand, treating herd-year-month effects as random would increase the effective number of daughters or the information with which an …

Reward Frequency: Effects On Flower Choices Made By Different Honeybee Races In Turkey, İbrahi̇m Çakmak, Harrington Wells
Reward Frequency: Effects On Flower Choices Made By Different Honeybee Races In Turkey, İbrahi̇m Çakmak, Harrington Wells
Turkish Journal of Zoology
We compared the European honeybee races Apis mellifera armeniaca, A.m. caucasica, A.m. cypria, and A.m. syriaca. These subspecies are endemic to very different habitats. Additionally, they are exposed to very different levels of predation. A.m. caucasica exists where honeybee predators typically are rare, while the remaining subspecies have ranges that coincide with areas where honeybee predators are abundant. Foraging decisions of workers visiting artificial flower patches containing blue, white, and yellow flowers were recorded. We tested whether foragers responded to differences in rewarding flower frequency among flower color morphs. Division of labor occurred among foragers of each race; some bees …

Ultrastructural Observations On The Development Of Some Actinosporean Types Within Their Oligochaete Hosts, Ahmet Özer, Rodney Wootten
Ultrastructural Observations On The Development Of Some Actinosporean Types Within Their Oligochaete Hosts, Ahmet Özer, Rodney Wootten
Turkish Journal of Zoology
Synactinomyxon type 1, aurantiactinomyxon type 3, echinactinomyxon type 5 and raabeia type 4 were studied at the TEM level in order to determine the developmental stages within their oligochaete hosts. All the actinosporean types studied had uninucleate cells as the earliest stage of development. The formation of a subsequent binucleate cell stage was either due to the division of the nucleus in a uninucleate cell or the plasmogamy of two uninucleate cells. The earliest pansporocyst formation seen was two outer somatic cells surrounding two inner generative \alpha and \beta cells in all the actinosporean types studied. However, the formation of …

Turkish Journal of Zoology
The structure of midgut endocrine cells of Agrotis segetum larvae was examined by light and electron microscopy. It was observed that the endocrine cells were located on the basal lamina and among the columnar epithelial cells of the midgut. The cells were morphologically determined as columnar or coniform. The cytoplasm of endocrine cells was observed to contain rough endoplasmic reticulum, mitochondria, developed Golgi complex, vesicles and numerous small secretory granules. It was also observed that the secretory granules were often located in the basal region of the endocrine cells.

Use Of A Discriminant Function For The Morphometric And Meristic Separation Of Whiting Stocks, Merlangius Merlangus Euxinus, Along The Turkish Black Sea Coast, Ali̇ İşmen
Turkish Journal of Zoology
Stock differentiation studies of whiting, Merlangius merlangus euxinus, from the Turkish Black Sea coast were carried out using morphometric and meristic characters and applying the generalised distance of Mahalanobis. Fifteen morphometric measurements, together with eleven meristic characters, were used in the analyses. Insufficient differences (P>0.01) in general phenotypic and genotypic characteristics implied the existence of a single unit stock. Samples taken in different periods showed lower similarity than those taken in the same periods.
