Distribution Pattern And Morphological Differences Between The Sexes Of River Blenny, Salaria Fluviatilis (Asso, 1801), In The Ceyhan River Basin, Turkey, Ahmet Alp, Cemi̇l Kara
Distribution Pattern And Morphological Differences Between The Sexes Of River Blenny, Salaria Fluviatilis (Asso, 1801), In The Ceyhan River Basin, Turkey, Ahmet Alp, Cemi̇l Kara
Turkish Journal of Zoology
The distribution of the river blenny (Salaria fluviatilis) in the Ceyhan River basin and the morphological differences between the sexes were investigated. Occurrence of the river blenny in the Ceyhan River basin depended on altitude of the habitats, and specimens were obtained at altitudes < 750 m. Samples were strongly female biased, which may have been due to the egg-guarding behavior of the males. There was also sexual dimorphism in that male blennies were larger than females (P < 0.05); however, there were no differences in the meristic counts between the sexes (P > 0.05). Analysis of variance showed that all of the standardized morphometric measurements were significantly different among the samples. In discriminant function analysis, morphological differentiation was determined between the sexes. Plotting discriminant function 1 to 2 separated the sexes from each other. Proportions of correctly classified individuals into their original groups were 71.9% for juveniles, 79.0% for …
Local Population Size And Dynamics Of The Color Polymorphic Bush Cricket, Isophya Rizeensis Sevgili, 2003 (Orthoptera: Tettigoniidae) Within The Fırtına Valley, İsmai̇l Kudret Sağlam, Seli̇m Süalp Çağlar
Local Population Size And Dynamics Of The Color Polymorphic Bush Cricket, Isophya Rizeensis Sevgili, 2003 (Orthoptera: Tettigoniidae) Within The Fırtına Valley, İsmai̇l Kudret Sağlam, Seli̇m Süalp Çağlar
Turkish Journal of Zoology
Isophya rizeensis Sevgili, 2003 (Orthoptera: Tettigoniidae) is a color polymorphic bush cricket endemic to the Fırtına Valley in the northeast of Turkey. This paper describes the local population size and dynamics of the species distributed in 13 different habitat patches within the Fırtına Valley. Local population size varied greatly between sites, and a 1-week delay in nymph emergence and maturation was recorded at the highest habitat patch relative to all habitat patches located at lower altitudes. The results given in this paper suggest that the I. rizeensis population in the Fırtına Valley constitutes a metapopulation made up of several local …
The Karyotype Of The Wild Boar Sus Scrofa Linnaeus, 1758 In Turkey (Mammalia: Artiodactyla), İrfan Albayrak, Si̇nan İnci̇
The Karyotype Of The Wild Boar Sus Scrofa Linnaeus, 1758 In Turkey (Mammalia: Artiodactyla), İrfan Albayrak, Si̇nan İnci̇
Turkish Journal of Zoology
This study is based on the karyological analyses of 4 Sus scrofa specimens obtained from Kırıkkale province in 2003 and 2005. It is the first time that karyotypes of Turkish wild boar specimens were determined. The diploid chromosome number (2n) is 38 and number of autosomal arms (NFa) 60. Karyological data were compared to the relevant literature. The results showed that the Turkish wild boar is different from central and western continental European specimens having 36 chromosomes and is identical to the domestic pig, and ones from east and south-east Europe and the Mediterranean islands.
The Morphology, Taxonomy, And Distribution Of Specimens Of Darevskia Clarkorum (Sauria: Lacertidae: Darevskia) Collected From Turkey’S Eastern Black Sea Region, Çeti̇n Ilgaz
Turkish Journal of Zoology
In all, 103 specimens of Clark's lizard, Darevskia clarkorum (Darevsky and Vedmederja, 1977), from 6 localities in the eastern Black Sea region of Turkey were examined in terms of pholidosis characteristics, morphometric measurements, and color and pattern features. Kolmogorov-Smirnov testing across all populations verified sexual dimorphism in the Ortacalar and Hemşin populations, regarding transversal series of ventral plates (P < 0.05). According to the Mann-Whitney U test, 16 pholidosis characteristics showed differences among the populations (P < 0.05). For comparison of morphometric measurements, 4 morphometric indices and ratios were developed. According to the results of independent t-testing, no differences were found between males and females among the populations. One-way variance analyses based on 4 morphometric indices and ratios confirmed that head index, snout-vent length/tail length, and tail length/total body length showed differences among the populations (P < 0.05). Regarding pholidosis characteristics (except rates of the presence of a masseteric plate and contact between the rostral and internasal plate), morphometric measurements, and color and pattern features, the specimens collected from 6 different localities were similar to D. clarkorum specimens mentioned in the literature. Furthermore, the known range of the species in Turkey has been extended.
