Manna Ash (Fraxinus ornus L.) in Turkey

Manna ash (Fraxinus ornus L.) is a very important tree species among hardwood taxa found in our country. This importance comes from the fact that it is a multi-purpose species. The species has been defined as an ornamental plant for urban planting sites due to its aesthetic characteristics. Furthermore, it is known that the species has not been affected much from climate changes and it possess tolerance against drought. In this study, the state and the importance of F. ornus in Turkey have been examined. In this context, botanical characteristics, natural distribution, site properties (soil, climate, and associated woody taxa), nursery studies and its utilization areas have been briefly reviewed

PREDICTING CONE PRODUCTION IN CLONAL SEED ORCHARD OF ANATOLIAN BLACK PINE WITH ARTIFICIAL NEURAL NETWORK

Seed orchards are an important seed source because they have the most important link between tree breeding and plantation forestry. The aim of this study is to evaluate the potential of Adaptive Neuro - Fuzzy Inference Systems of artificial neural networks to predict the amount of cone in clonal seed orchards of Anatolian black pine. It was found that the coefficient of determination (R 2 ), the mean absolute error (MAE) and the root mean square error (RMSE) of the artificial neural network model were 0.85, 14.83 and 18.85, respectively. The amount of cone in clonal seed orchards of Anatolian black pine was predicted with high efficiency through artificial neural networks. Considering the lack of forestry studies based on the artificial neural network, this study will enable further researches to provide a new perspective

The impacts of altitude and seed pretreatments on seedling emergence of Syrian juniper (Juniperus drupacea (Labill.) Ant. et Kotschy)

Background: Syrian juniper is an economically important species and in danger of extinction. For these reasons, the best seedling production methods of the species should be determined and its plantations should be established. The aim of the study is t

Investigation of temporal bone asymmetry in cases with unilateral tinnitus: morphometric and multicentric clinical study.

The aim of this multicentric study was carried out to compare the anatomical structures of temporal bones in patients with unilateral tinnitus in healthy ears. We also aimed at evaluating whether age- and gender-related asymmetrical changes occur in temporal bones or not. Fifty-two ears of 26 patients who had unilateral tinnitus were included into the retrospective study. The patients who had subjective nonpulsatile tinnitus and who previously had temporal computed tomography according to their file records were accepted to the study. Temporal computed tomography. scans and audiometric results of patients were examined retrospectively. Middle ear volume, diameter of internal acoustic meats, and diameter of jugular bulb were evaluated by both anatomist and radiologist, in an interobserver manner. Internal acoustic meats and jugular bulb were found to be larger in the ears that had tinnitus than in the healthy ears; however, there was no statistical significance. The stereological morphometric study of the correlation with sex of temporal bone asymmetry in humans is of importance for both otolaryngologists and anatomists. These results will contribute to data on middle ear volume, internal acoustic Meats, and jugular bulb sizes. (Folia Morphol 2013; 72, 1: 22-28
