Bioecology Of The Orthoptera Species Of The Setifian Plateau, North-East Algeria, Mustapha Bounechada, Salah Eddine Doumandji, Battal Çiplak
Bioecology Of The Orthoptera Species Of The Setifian Plateau, North-East Algeria, Mustapha Bounechada, Salah Eddine Doumandji, Battal Çiplak
Turkish Journal of Zoology
The bioecology of the Orthoptera species living in the Setif region of Algeria was studied between 1995 and 1999. The research was conducted at 12 ecologically homogeneous sites with typical biotopes for the Orthoptera species in the region. Thirty-six Orthoptera species were recorded, of which 6 belonged to Tettigonioidea and 30 to Acridioidea. The most abundant and frequent species in the area were Ocneridia volxemi (Bolivar, 1878), Dociostaurus maroccanus (Thunberg, 1815), Tmethis laevisculus (Krauss, 1892), Calliptamus wattenwyllianus (Pantel, 1896), Praephyppigera pachygaster (Lucas, 1849), and Platycleis laticauda Brunner, 1882. Orthoptera of the Setifian Plateau are divided into 4 groups according to …

Turkish Journal of Zoology
Currently, 4 species, Mesocricetus auratus, Mesocricetus raddei, Mesocricetus newtoni, and Mesocricetus brandti of the genus Mesocricetus are accepted as the valid taxa based on karyotype and morphologic features. A potential fifth species, Mesocricetus nigriculus, is under dispute and is currently listed as a subspecies of M. raddei, along with Mesocricetus raddei raddei and Mesocricetus raddei avaricus. UPGMA cluster analyses performed with biometrical measures confirm, only partially, the common separation of Mesocricetus hamsters into a Transcaucasian group with Mesocricetus newtoni, Mesocricetus brandti, and Mesocricetus auratus, and a Ciscaucasian group including the M. raddei subspecies. The status of M. nigriculus could not …

Mammalian Remains In The Pellets Of Long-Eared Owls (Asio Otus) In Diyarbakır Province, Seven Seçki̇n, Yüksel Coşkun
Turkish Journal of Zoology
This study was conducted with the pellets of Long-eared Owls from 2 sites in the area of Dicle University Campus, located in the north-eastern part of Diyarbakır Province, Turkey (lat 37°55'N, long 40°12'E). Pellets were collected at monthly intervals from July 2000 to June 2001 and the remains of 310 prey items were recovered from 211 pellets. The assemblages were composed mostly of small mammals. Eight species of mammals belonging to 2 orders (Insectivora: Crocidura suaveolens, and Rodentia: Microtus guentheri, Microtus sp., Mus musculus, Meriones tristrami, Cricetus cricetus, Rattus rattus, and Nannospalax ehrenbergi) were identified from the Long-eared Owl pellets. …

Test For Acute Toxicity Of Copper, Cadmium, And Mercury In Five Marine Species, Ermelinda Prato, Francesca Biandolino, Christian Scardicchio
Turkish Journal of Zoology
: The acute toxicity of copper (Cu), cadmium (Cd), and mercury (Hg) to the marine invertebrates Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, and Mytilus galloprovincialis were evaluated by static bioassays and calculation of the LC_{50} (lethality concentration for 50%). Hg was more toxic to Gammarus aequicauda, Corophium insidiosum, Idotea baltica, Sphaeroma serratum, and Mytilus galloprovincialis than Cu and Cd. Cu was the least toxic of the metals tested.

Turkish Journal of Zoology
In this study, age, growth, and sex ratio of 342 golden grey mullets, which were caught in fish traps during fishing season were determined. The samples were between 7.5 and 39.5 cm in length and were between < 1 and 4 years old. The length-weight relationship for this population was calculated as W = 0.01*L^{2.93}, L_{\infinity} = 43.2 cm, K = 0.33 yr^{-1}, and t_o = -0.30 yr. The male:female ratio of the population was 1:1.87 and first maturity was at the age of one year for both sexes.

Turkish Journal of Zoology
We examined 529 specimens of Mus domesticus and Mus macedonicus from Turkey, in terms of their morphological, bacular, and phallic aspects. The zygomatic index (ZI) varied from 0.32 to 0.47 in M. domesticus, and 0.60 to 0.85 in M. macedonicus. The head plus body length/tail length (H+B/T) index varied from 0.87 to 1.05 in M. domesticus, and 1.08 to 1.78 in M. macedonicus. The zygomatic plate is straight or convex in M. domesticus and M. macedonicus. The ventral wing of the parietal is generally tortuous in M. domesticus and is protruding or straight in M. macedonicus. The anterolabial cusp on …

Chromosomal Polymorphism In Thracian Populations Of Rattus Rattus (Linnaeus, 1758) (Rodentia: Muridae), Tolga Kankiliç, Nuri̇ Yi̇ği̇t, Teoman Kankiliç
Turkish Journal of Zoology
The black rat (Rattus rattus L.) from Thrace is an Oceanian type (2n = 38). Chromosomal analyses show that a polymorphism occurs in chromosome pairs no. 9, 10, and 13 due to pericentric inversions. In the studied populations, the frequencies of homozygous and heterozygous individuals did not differ from the Hardy-Weinberg equilibrium for chromosome pair no. 13. In both Gelibolu and Pınarhisar populations of R. rattus, a polymorphism due to the supernumerary B-chromosome was found. The R. rattus karyotype with supernumerary chromosomes is reported here for the first time in Turkey. The number of diploid chromosomes are 2n = 38, …

The Feeding Biology Of Ophisops Elegans Menetries, 1832 (Reptilia: Lacertidae) Populations Of The Bursa Region, Abdulmüttali̇p Akkaya, İsmai̇l Hakki Uğurtaş
Turkish Journal of Zoology
The feeding biology of Ophisops elegans inhabiting Bursa was investigated. Stomach contents of 66 adult (28 males, 38 females) specimens collected from 3 localities were investigated by numerical analysis. Most of the foods of the Ophisops elegans specimens were insects (64.58%), the majority of which were of larval form (19.44%). Two specimens that were collected from Gürsu were maintained in a terrarium to observe their feeding behaviors. During observations, Ophisops elegans exhibited various feeding behaviors depending on the type of prey and sometimes bit and ate pieces of its prey (legs, wings, etc.).

Hatching Success Of Original And Hatchery Nests Of The Green Turtle, Chelonia Mydas, In Northern Cyprus, Burcu Özdemi̇r, Oğuz Türkozan
Turkish Journal of Zoology
This paper provides information on the relation of abiotic factors (moisture content, nest depth, distance of nest from the sea and distance from vegetation) and a biotic factor (clutch size) with the hatching success of green sea turtles, Chelonia mydas, in original nests and hatcheries in Northern Cyprus. A hundred and twenty-nine randomly selected clutches (67 original and 62 hatchery) were examined. First, original and hatchery nests were tested separately and none of the factors were found to be associated with hatching success. Since no differences were detected between the original and hatchery nests in terms of hatching success, both …

A new subspecies, Mixobates brachypalpis ozkani subsp. nov., is described from a stream in the Rize region (Eastern Black Sea coast, Turkey). The new subspecies can be easily distinguished from the type material of M. brachypalpis, a species reported only from the locus typicus in Russia, by the more elongated and slender I-L-5/6. In addition, 3 water mite species (Torrenticola oraviensis (Láska, 1953), Torrenticola thori (Halbert, 1944) and Mideopsis roztoczensis Biesiadka and Kovalik, 1979) are reported for the first time from Turkey.

A total of 288 dairy cattle from 4 different closed barns were sampled in order to investigate the presence of bovine viral diarrhoea virus (BVDV) infection. Based on the data gathered from neutralisation peroxidase-linked antibody (NPLA) tests, which were conducted to detect BVDV antibodies, all of the barns monitored previously had the infection; the rates of seropositive animals were between 44% and 100%. Overall, the results obtained from Aydın province showed that 248 of the 288 dairy cows (86%) monitored were seropositive. BVDV antigen ELISA kits (Bio-X Diagnostics- Belgium) were used to detect BVDV antigen (NS3 protein) in blood samples. …

This experiment was conducted to study the effects of micron Astragalus, 80 mesh Astragalus and Astragalus polysaccharide (APS) on antimicrobial peptides PR-39 and protegrin-1 gene expression in pigs using semi-quantitative RT-PCR analysis. One hundred twenty 60-day-old Duroc x Landrace x Yorkshire piglets (21.88 ± 1.26 kg of average initial body weight) were randomly allotted to 4 treatments. Each treatment had 3 replicates (i.e. pens) with 10 pigs per pen. The basal diets were supplemented with 0, 5 g kg^{-1} APS, 5 g kg^{-1} 80 mesh Astragalus, and 5 g kg^{-1} micron Astragalus, respectively, and the feeding experiment lasted 30 days. …
