Taxonomic Status And Distribution Of Apodemus Mystacinus (Danford And Alston, 1877) (Mammalia: Rodentia) In Turkey, Ercüment Çolak, Nuri̇ Yi̇ği̇t, Reyhan Çolak, Mustafa Sözen, Şaki̇r Özkurt, Tolga Kankiliç

Turkish Journal of Zoology

Morphological, biometrical, karyological, bacular and phallic aspects of Apodemus mystacinus populations in Turkey were studied based on 117 specimens. The biometrical and phallic comparisons confirmed the distinctness of A. m. mystacinus and A. m. epimelas. The UPGMA tree divided populations in Turkey into 2 groups. The distance (D) between A. m. mystacinus and A. m. euxinus was 0.469. A. mystacinus had karyotypic values of 2n = 48, NFa = 50, and NF = 52. Being different from A. m. epimelas, there was a short groove in the dorsal view of the phallus in populations of A. m. mystacinus in Turkey.

The main characteristics of these species and formae are described in detail and compared with those of similar ones previously reported.


The Birds Of Dicle Dam (Diyarbakır), Recep Karakaş, Ahmet Kiliç Jan 2004

The Birds Of Dicle Dam (Diyarbakır), Recep Karakaş, Ahmet Kiliç

Turkish Journal of Zoology

The birds of Dicle Dam, which is located 50 km north-east of Diyarbakır city centre, were studied between February 2000 and February 2002. During the observation period 116 bird species that belong to 15 orders and 38 families were determined and listed. Among these species defined, 44 of them certainly and 26 presumably breed in the area, while 46 of them are transitory migrating or wintering birds for the region. Three species are globally under threat. The determination of bird species will help in the evaluation and comparison of possible changes regarding the bird fauna in the future.

An Implicit Surface Modeling Technique Based On A Modular Neural Network Architecture, Manuel Carcenac Jan 2004

An Implicit Surface Modeling Technique Based On A Modular Neural Network Architecture, Manuel Carcenac

Turkish Journal of Electrical Engineering and Computer Sciences

Independently from artificial intelligence applications, an artificial neural network can be viewed as a powerful tool for function reconstruction. Previous papers used this property to model an implicit surface out of some control points by reconstructing its underlying scalar field. Such an approach requests the neural network to memorize the control points, which has turned problematic for complex surfaces. In our paper, we show that this problem can be efficiently tackled by adapting the architecture of the neural network to the features compounding the surface: by learning first these features independently and then blending them gradually together, our modular architecture …

Turkish Journal of Veterinary & Animal Sciences

The shelf life of fishballs prepared using raw and boiled fish was examined during cold storage (+4 ºC ± 1). Sensory, physical (loss of weight), chemical (TVB-N, TMA-N) and microbiological analyses (aerobic mesophilic bacteria, total psychrophilic bacteria) of fishballs made from raw and boiled anchovies and stored under cold storage conditions were carried out every 3 days. All analyses were carried out with two repetitions. The shelf life of fishballs was 9 days at +4 ºC ± 1 according to the results of the sensory, physical, chemical and microbiological analyses.

The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z Jan 2004

The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of the addition of 0.5% urea or 0.5% urea plus 4% (w/w) molasses into corn varieties (Rx-947, 33-94, Frassino, and Arifiye) harvested at the early-milk stage on silage quality, in vitro digestibility and digestible dry matter (DM) yield. The addition of urea into silage increased the CP content (P < 0,05). The neutral detergent fiber and acid detergent fiber contents of the control silages were 69.40 and 38.68 for Rx-947, 69.34 and 38.69 for 33-94, 62.67 and 34.93 for Frassino, and 64.35 and 37.04 for Arifiye (P < 0,05). The addition of urea or urea plus molasses into silage increased the silage pH in all varieties, except for Rx-947 (P < 0,05). The lactic, acetic, propionic and butyric acid contents of the silage samples were between 23.2 and 153.3, 7.8 and 23.4, 0.6 and 1.6, and 0.0 and 0.54 g/kg DM, respectively. The addition of urea or urea and molasses into Rx-947 and Frassino varieties and the addition of urea only into the 33-94 variety increased silage lactic acid levels. The addition of urea and molasses into Rx-947, Frassino and Arifiye varieties also increased silage acetic acid levels (P < 0,05). There was a significant difference only between the Frassino and Arifiye varieties on this parameter (P < 0,05). The addition of urea only into silage decreased DM digestibility; the addition of molasses with urea, however, eliminated this negative effect of urea on digestibilit in all varieties, except for Frassino (P < 0,05). Digestible DM yields of untreated silage were 863.68, 1142.43, 1044.43, and 1075.07 kg/decare (10 decares = 1 hectare) for Rx-947, 33-94, Frassino and Arifiye, respectively (P < 0,05). The digestible DM yield of untreated Rx-947 silage was significantly lower than those of the others (P < 0,05). It can be concluded that corn varieties harvested at the early-milk stage (20% DM) can be ensiled, and that urea and molasses can be used as silage additive to increase CP and energy content of silages.

Karyotype Analyses Of The Tench (Tinca Tinca L., 1758) Living In Lake Mogan (Ankara), Mustafa Hamalosmanoğlu, Mustafa Kuru

Turkish Journal of Veterinary & Animal Sciences

Chromosome numbers and structures were investigated in (Tinca tinca L., 1758) of the family Cyprinidae. A solution of 1 ml/100 g of 0.1% colchicine was injected intramuscularly. Four hours later the fish were killed and the kidney and gills were removed and cytogenetic methods were applied. Metaphase chromosomes of the cells in these tissues were investigated numerically and morphologically. It was determined that the fish have 2n = 48 diploid chromosomes made up of 6 pairs of metacentric, 8 pairs of subtelocentric and 10 pairs of acrocentric. The average haploid chromosome length was 2.191 µ. The chromosomes were named and …

Turkish Journal of Veterinary & Animal Sciences

A data set containing 2-year test day milk yield records was used. Random regression model solutions established with a covariance function (CF) approach was used. Persistence and lactation curve explanation performances of polynomial, Wilmink and Ali-Schaeffer curve definitions were compared for CF. When comparisons were made for R2 values, polynomial (0.9835) definition headed the list, followed by the Ali-Schaeffer curve (0.9534), and Wilmink curve (0.6023) definitions. Among the persistence predictions in respect of lactation orders, the Ali-Schaeffer curve provided predictions with the minimum variance, followed by the Wilmink and polynomial curve approaches.

Effect On Aflatoxin Formation Of Different Storage Conditions In Tulum Cheese Inoculated With Aspergillus Parasiticus Nrrl 2999, Mustafa Gürses, Ahmet Erdoğan, Selahatti̇n Sert

Turkish Journal of Veterinary & Animal Sciences

Tulum cheese was divided into 2 equal parts. One part was inoculated with 10^4 spores/g of aflatoxin-producing Aspergillus parasiticus NRRL 2999 strain. The other part, the control group, was not inoculated. All the samples were ripened in glass jars at 2 different temperatures (10 ± 1 and 20 ± 1 °C) and relative humidities (85 ± 2% and 95 ± 2%) and analyzed for aflatoxin formation on days 1, 15, 30, 45, 60 and 90 of storage using thin layer chromatography.
