Ultrastructural Study On The Ovarian Wall And The Oviduct Of The Asellus Aquaticus (Crustacea: Isopoda), B. Melike Erkan
Ultrastructural Study On The Ovarian Wall And The Oviduct Of The Asellus Aquaticus (Crustacea: Isopoda), B. Melike Erkan
Turkish Journal of Zoology
In this study the ovarium, ovarian wall and oviduct of Asellus aquaticus ( A. aquaticus) (Crustacea: Isopoda) were investigated by stereomicroscopy, phase contrast microscopy and light microscopy. Long, tube-shaped, separate ovaries of A. aquaticus are located dorsolateral to the gut. The germinal zone is confined to the ventral region of the ovary as a thin band. The ovarian wall is composed of a few fibrous layers. The oviduct is located in the anterior one-third of the ovary, not in the central part. The sheath of the oviduct was found to possess some muscle cells, a feature first noted in this …

Turkish Journal of Zoology
In this preliminary study, nine Stone Martens were recorded from different localities in Turkey. Their morphological characteristics were found to be consistent with previously published papers. However, the throat patches of Turkish Stone Martens show variations with respect to shape. In addition, it was determined that the morphologic and biometric characteristics of Turkish samples were consistent with those of M. f. syriaca. According to the karyological findings, the diploid number of chromosomes and the fundamental number were 38 and 76, respectively.

Turkish Journal of Zoology
The toxicity of a neem extract RB-a in comparison with a pyrethroid, Coopex, was studied along with their effects on GPT and GOT activities and oxygen consumption in S. oryzae. The LD 50 value of Coopex was found to be 6.128 \mug/cm 2 whereas RB-a was found not to be an acute contact poison. Even at a dose of 1257 \mug/cm 2 it could cause 34% mortality of S. oryzae. The oxygen consumption under the effects of Coopex was found to decline less i.e. at 6.12 \mug/cm 2 from 0.0005191 to 0.0006589, as compared to RB-a where the rate of …

Turkish Journal of Zoology
This report describes the determination of the toxicity of two pesticides, neem formulation (RB-a+PBO+Tx-100) and fenpropathrin, on Alphitobius diaperinus adults. The mortalities caused by the two compounds were found to be 70% for a 117.8\mug/cm 2 dose of neem formulation, and 88% for a 1.96 \mug/cm 2 dose of synthetic pyrethroid, fenpropathrin (Danitol). The LD 50 value of Danitol was found to be 0.2749 \mug/cm 2 , and that of neem formulation was found to be 58.92 \mug/cm 2 . Danitol-treated Alphitobius diaperinus adults showed inhibitions of 44.66% and 45.91% in GPT and GOT activity, respectively, Whereas insects treated with …

Influence Of Sediment On Heavy Metal Uptake By The Polychaete Arenicola Marina, Levent Bat
Influence Of Sediment On Heavy Metal Uptake By The Polychaete Arenicola Marina, Levent Bat
Turkish Journal of Zoology
In this study, the suitability of the polychaete Arenicola marina as a test organism using clean intertidal sediment contaminated with copper, zinc and cadmium was evaluated. Metal levels in casts were significantly lower than in unworked sediment indicating that the bioturbatory activity of lugworms might be significant in the distribution of the pollutants. This study showed that sediments contaminated with specific pollutants affected the uptake of these pollutants by Arenicola in a predictable and dose–dependant way and gave further justification for the use of this species in sediment toxicity tests.

A New Subspecies Of Jerboa From Turkey;Allactaga Euphratica Kivanci Subsp. N., Ercüment Çolak, Nuri Yi̇ği̇t
Turkish Journal of Zoology
In this study, 42 specimens of Allactaga euphratica from Urfa (Turkey) were examined based on morphological, cranial, external and karyological characters. A comparison of specimens from Urfa with those from Syria, Jordan, Kuwait and Iraq showed that specimens from Urfa, Syria and Jordan, Kuwait and Iraq showed that specimens from Urfa, Syria and Jordan differ from those from Kuwait and Iraq. Thus, specimens from Urfa (Turkey), Syria and Jordan were included in a new subspecies, Allactaga euphratica kivanci subsp. n.

Physiological Energetics Of Buccinum Undatuml. (Gastropoda) Off Douglas,Isle Of Man (The Irish Sea), Ahmet E. Kideyş
Turkish Journal of Zoology
Physiological energetics of the common whelk ( Buccinum undatum) were studied in a population off Douglas, Isle of Man and an energy budget was constructed for the period February 1989 to January 1990. The components of the energy budget (in kJ m -2 year -1 ) for the population can be summarized thus: consumption (C)=753; growth production (P g )=34; reproductive production (P r )=4; mucus production=218; respiration (R)=96; ammonia excretion (U)=8; and faecal production (F)=393. Assimilation efficiency was 47.7%. P/B (annual production/biomass) was calculated as 1.40 representing an intermediate life span for this species.

Turkish Journal of Zoology
In this study, the Turkish population of Rattus norvegicus and Rattus rattus were studied with regard to external, cranial, phalli, bacula and tooth crown morphology and karyotype. External, internal and karyologic characteristics of R. norvegicus were found to be consistent with previously published results. Additionally, it was determined that there are striking color variations in the dorsal and ventral fur of R. rattus and that crown morphology is not a definitive characteristic distinguishing these species because of connected lobes in old specimens. According to the karyological studies, the diploid chromosome numbers and fundamental numbers of R. norvegicus and R. rattus …

Turkish Journal of Zoology
Concentrations of cadmium, lead, copper, chromium and nickel were determined in the gill, liver and muscle of Cyprinus carpio, Barbus capito and Chondrostoma regium caught at 5 stations on the Seyhan river system. Heavy metal concentrations in the tissues tended to vary significantly among stations, and one station thought to be contaminated by hospital effluents showed particularly high metal concentration. Liver and gill tissues showed higher metal concentrations than muscle tissue. The ranges of mean metal concentrations (µg/g d.w.) were as follows: the range of cadmium concentration was 1.26-6.10, 0.96-4.72 and 0.51- 1.67, that of lead was 9.41-44.75, 5.22-37.15 and …

Hibernation And Body Weight In Dormice, Glis Glis Orientalis(Nehring, 1903) (Rodentia: Gliridae), Maintained Underuncontrolled Conditions, Ercüment Çolak, Nuri Yi̇ği̇t, Mustafa Sözen, Şakir Özkurt
Turkish Journal of Zoology
Hibernation pattern and changes in the body weight of juvenile and adult dormice, Glis glis orientalis, kept in uncontrolled conditions were investigated. It was determined that G.g.orientalis entered hibernation on October 28 when its body weight was 180 g and the ambient temperature was below 18 ºC, which seems to be the critical temperature for entering hibernation. Although body weight has an important role in entering hibernation at the beginning of the hibernation season, dormice hibernated as the hibernation season progressed regardless of their body weight. Adult dormice arose from hibernation during the period of May 13 to June 6. …

Early Development Of Barbel ( Barbus Barbus L.) Larvae, Metin Çalta
Turkish Journal of Zoology
In this study, the early development of barbel ( Barbus barbus L.) larvae has been determined by measuring their wet weight, dry weight, whole body mineral content (Ca, Mg, Na and K), skeletal development and gill development. It has been observed that wet weight, whole body mineral contents, the number of lamellae per filament of gill and the number of calcified vertebrae of larvae during early development stage increased by age, whereas dry weight decreased. The increase of whole body magnesium content has been very low compared with that of other minerals. In addition, a possitive relationship between whole body …
