Androgenesis: The Best Tool For Manipulation Of Fish Genomes, Minal P. Bhise, Tariq A. Khan Jan 2002

Androgenesis: The Best Tool For Manipulation Of Fish Genomes, Minal P. Bhise, Tariq A. Khan

Turkish Journal of Zoology

Androgenesis involves the development of an organism with only paternal chromosomes. The induction of androgenesis using diploid sperm, highly effective UV-irradiation of egg, dispermy using heterologous eggs, the possibility of producing supermales for all male production and the recovery of cryopreserved sperm are recent technological developments in androgenesis in fish. However, few researchers have successfully produced viable diploid androgens in fish. The authors made an attempt to induce androgenesis in the common carp (Cyprinus carpio L.) and the results are discussed along with the potential applications of androgenesis in conserving fish genomes and current knowledge on inducing androgenesis in fish.

Seasonal Fluctuation In The Rotifer Fauna Of Kesikköprü Dam Lake (Ankara, Turkey), Si̇bel Yi̇ği̇t

Turkish Journal of Zoology

The individual and seasonal variations of 11 rotifer species identified in Kesikköprü Dam Lake were investigated from April 1995 to May 1996. Species-wise percentages were Polyarthra vulgaris 24.5%, Keratella quadrata 20.8%, Asplanchna priodonta 16.0%, Brachionus angularis 11.2%, Keratella cochlearis 8.8%, Synchaeta litoralis 7.0%, Lecane luna 4.0%, Notholca squamula 3.8%, Lepadella patella 1.6%, Notholca acuminata 1.4% and Colurella adriatica 0.7%.

Community Structure Of Macrobenthos Of A Southeast Texas Sand-Pit Lake Related To Water Temperature, Ph And Dissolved Oxygen Concentration, Kemal Çeli̇k

Turkish Journal of Zoology

Water temperature (°C), pH, dissolved oxygen concentration (mg/l) and the community structure of the macrobenthos of a small southeast Texas sand-pit (Barry's) lake were studied from June 1995 to February 1996, which covered climatic extremes. The lake was a warm monomictic lake and no anoxic conditions were observed at any depth during the entire study period. A total of 50 taxa and 5614 individuals of macrobenthos were collected. The dominant organisms were Chaoborus punctipennis (Say), Limnodrilus hoffmeisteri (Claparede), and Dero obtusa (Udekem).

The Toxic Effects Of Malathion (Organophosphate Insecticide) On The Daphnia Magna Straus, 1820 (Crustacea, Cladocera), Maryam Rassoulzadegan, Nusret Akyurtlakli Jan 2002

The Toxic Effects Of Malathion (Organophosphate Insecticide) On The Daphnia Magna Straus, 1820 (Crustacea, Cladocera), Maryam Rassoulzadegan, Nusret Akyurtlakli

Turkish Journal of Zoology

The toxic effects of technical grade (95 %) malathion and commercial (25 %) malathion were investigated on young (£ 24 h old) Daphnia magna in static acute toxicity tests (24 and 48 h). The culture of D. magna and toxicity tests were performed at 24 ± 1 ºC with a photoperiod of 16 h light and 8 h dark. To obtain a healthy population, the fecundity of each female in their life cycle was also investigated. The immobilization of daphnids was considered for determination of the 24 h / 48 h effective concentration (50 %). The EC50 values were found …

Impact Of Two Sublethal Concentrations Of Copper Chloride And Chlorine On The Excretory Products Of Crab Sesarma Quadratum (Fabricius), Santhana Valarmathi, Jayapaul Azariah Jan 2002

Impact Of Two Sublethal Concentrations Of Copper Chloride And Chlorine On The Excretory Products Of Crab Sesarma Quadratum (Fabricius), Santhana Valarmathi, Jayapaul Azariah

Turkish Journal of Zoology

Excretion in estuarine animals is considered to be an important factor in assessing their physiological status. The pattern of oxygen consumption and excretion patterns (ammonia and nitrite) in medium size mud crabs of S. quadratum (3 to 4 g weight) were studied under laboratory conditions at two sublethal concentrations of 1/10 and 1/3 of the LC_{50} value of copper chloride and chlorine. The rates of oxygen consumption and excreted products were negatively correlated to the sublethal concentrations of the toxicant. Reduced rates of oxygen consumption and excretion of ammonia and nitrite were observed when exposed to these sublethal concentrations.

Metadinium banksi was observed in rumen contents from a single goat out of eight living in southeastern Turkey. It constituted 0.25% of the total ciliate population and had a 12.5% frequency of appearance. The size and percentage occurrence of this species in the present study are compared to those previously reported for other animal hosts living in different geographical locations. This study reports for the first time in Turkey the presence of Metadinium banksi in arctic ruminants.

New Distributional Records For Rana Bedriagae Caralitana In Anatolia, Uğur Kaya, İ. Ethem Çevi̇k, Uğur C. Eri̇şmi̇ş

Turkish Journal of Zoology

We conducted a herpetofaunal survey on the southern part of the Lake District in Anatolia searching and documenting new sites for herptile species. During the two years of our study three new sites, Gencek Lake (Derebucak/Konya), Derebucak (Konya) and Tınaztepe (Seydişehir/Konya), were recorded for Rana bedriagae caralitana. Of these, the two southernmost records extend the distribution of these subspecies in the Lake District of Anatolia.

Age Determination Of Shad (Alosa Pontica Eichwald,1838) Inhabiting The Black Sea, Savaş Yilmaz, Nazmi̇ Polat Jan 2002

Age Determination Of Shad (Alosa Pontica Eichwald,1838) Inhabiting The Black Sea, Savaş Yilmaz, Nazmi̇ Polat

Turkish Journal of Zoology

The most reliable bony structure and method were investigated for age determination of shad (Alosa pontica Eichwald, 1838) inhabiting the Black Sea. Therefore, five bony structures such as scale, vertebra, otolith, opercle and subopercle were removed from 240 individuals collected from April 1998 to April 1999. Each bony structure was prepared for age determination by different techniques, and examined by binocular microscope. Mean ages were estimated for each bony structure-reader combination and the precision of age estimated from multiple readings was evaluated. Furthermore, the error of ageing was calculated. Vertebra was the most reliable bony structure for ageing this species …

Turkish Journal of Zoology

This experiment was conducted between 15th February 2000 (day 1) and 31st January 2001 (day 350) at the DSI-Gölköy Fish Production Station, Bolu (Turkey). Abant trout larvae obtained from eggs of wild Abant trout broodstocks in Lake Abant and rainbow trout larvae obtained from eggs of the hatchery broodstocks in Gölköy Fish Production Station were used. Trials I and II involved eight groups (four Abant and rainbow trout experimental groups, and four Abant and rainbow trout parallel groups). A total of 1784 larvae was used in both the trials. At the end of the experiment, although the mean wet weight …

Aging Coyotes Using Dental Characteristics, Michelle Maher Jan 2002

Aging Coyotes Using Dental Characteristics, Michelle Maher

Masters Theses

The accepted methods of age determination in the coyote (Canis latrans) are either highly subjective and unquantifiable or expensive and require the extraction of the canine tooth. Since neither of these methods are ideal, their limitations have impeded research on this species. Therefore, it was my objective to (1) develop and test the accuracy and precision of a descriptive key based on tooth wear patterns on the lower canine tooth, (2) develop and test the reliability of multiple regression models for aging coyotes using measurements from extracted teeth, and (3) suggest criteria for improving the consistency of results …
