A Behavioral Analysis Of Achromatic Cue Perception By The Ant Cataglyphis Aenescens (Hymenoptera; Formicidae), Volkan Aksoy, Yilmaz Çamlitepe
Turkish Journal of Zoology
Behavioral responses of Cataglyphis aenescens foragers to various monochromatic light stimuli were tested. Foragers were trained to associate lights of 370 (UV), 440 (blue), 540 (green), and 640 nm (red) with a food reward on a circular orientation platform and were then tested to determine the threshold intensity values of these wavelengths they could perceive. Foragers significantly responded to all wavelengths at training intensities but their homeward orientation diminished with decreasing stimulus intensity. The results showed that UV and green lights could be perceived at lower intensities compared to blue and red lights. Foragers were further trained in a Y-maze …

Selective Predation On Common Voles By Tawny Owls And Long-Eared Owls In Winter And Spring, Linas Balciauskas, Laima Balciauskiene
Turkish Journal of Zoology
We studied size preferences of Tawny (Strix aluco) and Long-eared (Asio otus) Owls preying on common voles (Microtus arvalis) in the winter and spring seasons in Central Lithuania. Regression equations were used for body mass estimations. We found that both A. otus and S. aluco preferred larger M. arvalis than the average available in the population (the average body mass of predated individuals was 21.45 ± 0.12 g compared to 16.42 ± 0.16 g of snap-trapped individuals). Irrespective of the owl species, most of the predated Microtus voles were adults. In S. aluco prey, the winter proportion of young voles …
Local Concentration Of Foraging Noctule Bats (Nyctalus Noctula) As A Possible Tool To Assess The Density Of Bats In Large Forest Complexes, Michal Polakowski, Monika Broniszewska, Ireneusz Ruczynski
Local Concentration Of Foraging Noctule Bats (Nyctalus Noctula) As A Possible Tool To Assess The Density Of Bats In Large Forest Complexes, Michal Polakowski, Monika Broniszewska, Ireneusz Ruczynski
Turkish Journal of Zoology
Concentrations of at least 600 hunting noctule bats Nyctalus noctula were observed over the artificial shallow reservoir Siemianówka in eastern Poland. The observation indicates that noctule bats concentrate hunting during the presence of vast amounts of insects over the reservoir. We suggest that the high concentrations of noctule bats provide a potential tool for the estimation of local population size or density in large forest complexes.

Phoretic Mites In Uni- And Bivoltine Populations Of Ips Typographus: A 1-Year Case Study, Martin Cejka, Jaroslav Holusa
Turkish Journal of Zoology
Members of the order Mesostigmata frequently use other animals to colonize suitable habitats, and thus their phoretic exploitation of bark beetles is not exceptional. We compared the abundance and species spectrum of phoretic mites in univoltine and bivoltine populations of the European spruce bark beetle Ips typographus. Two localities with high population densities of Ips typographus in the eastern part of the Czech Republic (400 and 1100 m a.s.l.) were studied. Beetles were sampled with pheromone traps baited with IT Ecolure (5 per locality). In total, 1268 I. typographus individuals were captured, from which 1662 mite individuals were collected and …

Application Of Dietary Fish Oil In Dairy Cow Reproduction, Anna Zwyrzykowska, Robert Kupczynski
Turkish Journal of Veterinary & Animal Sciences
Feed fats are commonly used as a component of high-yielding cow diet rations. Many studies have been conducted on the effects of fat supplementation on metabolism, milk composition, and improvements in dairy cow reproduction. The positive effects on fat (vegetable oil) and energy supplementation on improvements in reproduction are well documented. Consumption of polyunsaturated fatty acids (PUFAs), including n-3 acids, in appropriate feed doses improves fertility of dairy cows. A fat source with high levels of acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is marine oil, especially fish and algae. By modification of cow rations, EPA and …

Molecular, Cellular, And Physiological Determinants Of Bull Fertility, Alexis Marie Parisi, Shannon Kate Thompson, Abdullah Kaya, Erdoğan Memi̇li̇
Turkish Journal of Veterinary & Animal Sciences
Bull fertility, defined as the ability of the spermatozoon to fertilize and activate the ovum and then support embryonic and even fetal development, is a crucial factor influencing animal reproduction and production efficiency. Despite significant influences of fertility on herd genetic improvement and efficient cattle production, the mechanisms regulating this phenotype and reliable biomarkers associated with bull fertility are poorly defined. Specifically, there is a broad lack of knowledge in bull fertility. In this paper, bull fertility is reviewed within the context of animal systems physiology, and system biology markers associated with bull fertility are provided. This mini-review is intended …

Cholesterol Efflux From Sperm: Approaches And Applications, Zahid Naseer, Ejaz Ahmad, Meli̇h Aksoy
Turkish Journal of Veterinary & Animal Sciences
Following ejaculation, sperm appear morphologically mature, but functionally they are inactive. To attain functional capability or capacitation in vivo, sperm must reside in the female reproductive tract for a certain period of time before fertilization. In the female reproductive tract, cholesterol efflux from the sperm plasma membrane is considered vital for the initiation of capacitation. A number of in vitro studies have used biological and nonphysiological means to understand the phenomenon of cholesterol efflux and capacitation. In this review, we present a short overview of the role of cholesterol efflux in regulating sperm capacitation using various agents. This review provides …

Expression Of Vascular Endothelial Growth Factor And Hypoxia-Inducible Factor-1 Alpha During The Periovulatory Period In Goats, Chainarong Navanukraw, Jiratti Thammasiri, Tossapol Moonmanee, Jaruk Nutthakornkul
Turkish Journal of Veterinary & Animal Sciences
To evaluate the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1 alpha (HIF-1 alpha) during the periovulatory period, goat ovaries were collected at 0, 4, 8, 12, 24, and 48 h after treatment with 300 IU hCG. Total cellular RNA was isolated and VEGF and HIF-1 alpha were quantified using real-time RT-PCR. The mRNA levels of VEGF in thecal tissue remained unchanged prior to ovulation. However, the mRNA levels of VEGF in thecal tissues at 48 h increased to 7.5-fold of the level at 0 h (P < 0.05). In granulosa tissue, the VEGF mRNA levels were not detected in granulosa cells at 48 h. In thecal tissue, the mRNA level of HIF-1 1 alpha at 4 h was 1.5-fold of the level at 0 h and remained unchanged during 8-24 h; however the levels were significantly increased at 48 h. The mRNA levels of HIF-1 alpha in granulosa at 4 h was not changed but levels were increased (P < 0.05) at 8 h and at 12 h and then decreased at 24 and 48 h, respectively. These data describe the relationships of VEGF- and HIF-1 alpha -dependent angiogenesis during the periovulatory periods by which hypoxia during ovulation is crucial for establishing the thecal new vasculature.

Turkish Journal of Veterinary & Animal Sciences
Ninety-two umbilical pathologies were surgically treated in Holstein, Aberdeen Angus, and Polled Hereford calves, both males and females, whose ages ranged between 2 and 8 months. The pathology diagnosis was performed considering the main anatomical elements involved in the umbilical cord, the inflammation progression, and the macroscopic characteristics of injuries. The umbilical cord pathologies were related to calving characteristics. The proportion of affected umbilical cords in calves born via assisted calving (77%) was significantly higher than that observed in calves born from normal parturition. The umbilical cord pathology of highest occurrence was omphalophlebitis (53.2%). A considerable proportion of infectious diseases …

Turkish Journal of Zoology
In this study, the breeding ecology and behaviour of the Great Reed Warbler, Acrocephalus arundinaceus, was studied at Poyrazlar Lake, Turkey. The breeding period started in the first week of May. The incubation period lasted 14 days. As clutch size increased, the diameter of the nests became larger (r = 0.65). Diameters of nests containing different clutch sizes varied significantly from one another (P < 0.01). However, their height did not change (r = 0.24). There was no significant height difference between nests containing different clutch sizes (P > 0.05). As the nests became farther from the shore, the clutch size and the egg weight increased, because mature adults built their nests on the reeds in deeper areas (r = 0.59, r = 0.73). On …

Facultative Paedomorphosis In A Population Of Lissotriton Vulgaris (Amphibia: Salamandridae) From The Danube Delta Biosphere Reserve (Romania), Florina Stanescu, Elena Buhaciuc, Paul Szekely, Diana Szekely, Dan Cogalniceanu
Turkish Journal of Zoology
Facultative paedomorphosis refers to the simultaneous expression of 2 different phenotypes (i.e. paedomorphic and metamorphic) within the same population. Over the last 6 decades, this phenomenon was reported from only 5 populations of smooth newt Lissotriton vulgaris (Linnaeus, 1758) in Romania. In the spring of 2011, we found a new facultative paedomorphic population. The sample was female-biased, thus suggesting a sex-dependent expression of the paedomorphic phenotype. Most of the populations recorded in Romania were found in permanent water bodies with abundant vegetation.

Time-Activity Budgets Of Wintering Ferruginous Duck, Aythya Nyroca, At Gajoldoba Wetland, Jalpaiguri, India, Tanmay Datta
Turkish Journal of Zoology
Results indicate resting as the main diurnal activity of Aythya nyroca, whereas feeding dominated during the night. Other than resting (56.3%), feeding (16.8%) and swimming (15.2%) were major activities of the diurnal time-activity budget, whereas preening (9.4%) and flying (2.3%) were less frequent and occupied a secondary rank. Feeding and swimming were prevalent during the morning and afternoon hours. During midday, most of the ducks indulged in resting. The small amount of time spent on diurnal feeding was compensated by voracious nocturnal feeding (64.6%), which peaked in the middle of the night. Human interference plays an important role in shaping …
