Morphometric And Allozymic Differences Between Bearded Tit Panurus Biarmicus (Aves: Passeriformes) Subpopulations In A Large Wetland And A Small Pond In Central Anatolia, Turkey, Fulya Saygili, Nuri̇ Yi̇ği̇t, Pinar Çam, Duygu Yüce

Turkish Journal of Zoology

The Bearded Tit (Panurus biarmicus) is a small passerine bird occurring only in wetland habitats. Three subspecies of the Bearded Tit are known from Turkey. The endemic subspecies Panurus biarmicus kosswigi has only been recorded from Amik Lake in Turkey. This subspecies is now considered extinct; the apparent cause of this extinction was the drought affecting the lake. Other subpopulations might be similarly threatened by habitat loss. Therefore, it is important to investigate the morphometric characteristics and genetic variation of these local subpopulations. In this study, body weights and 12 morphometric characters were measured for Bearded Tit individuals in the …

Ground Beetles (Coleoptera: Carabidae) Of Azarbaijan, Iran, Ahmad Atamehr

Turkish Journal of Zoology

The Carabidae family (Coleoptera) is among the dominant groups of terrestrial predators and includes more than 40,000 species worldwide, making it one of the largest families of beetles. The fauna of Carabidae in Azarbaijan, Iran, is very diverse and has not been studied thoroughly. In the following paper, this group of beneficial predators is studied, using samples taken through 2007-2010 across Azarbaijan. Species belonging to 12 subfamilies were collected from 24 different localities. Among this diverse fauna, 3 species, Broscus cephalotes (Linnaeus, 1758), Harpalus (Pseudoophonus) calceatus (Duftschmid, 1812), and Amara (Xenocelia) ingenua Duftschmid, 1812 are new records for Iranian fauna.

Comparison Of Two Morphometric Methods For Discriminating Honey Bee (Apis Mellifera L.) Populations In Turkey, Ayça Özkan Koca, İrfan Kandemi̇r

Turkish Journal of Zoology

In this study, we compared 2 different methodologies (traditional morphometrics, TM, and geometric morphometrics, GM) in order to determine their ability to discriminate the honey bee populations distributed throughout Turkey. In TM, 16 morphometric characters were measured from the forewings of different honey bee populations from Turkey. A total of 20 landmarks were utilized for the GM analysis. Multivariate statistical analysis of data obtained from the 2 methodologies showed that GM was more successful (81.5%) than TM (70.4%). While the GM method is much simpler and easier compared to the standard morphometric measurement of size characters and angles of wing …

Terrestrial Bdelloid Rotifers From Erzurum (Eastern Part Of Turkey), Murat Kaya Jan 2013

Terrestrial Bdelloid Rotifers From Erzurum (Eastern Part Of Turkey), Murat Kaya

Turkish Journal of Zoology

There has been a growing interest in studies of the macroecology and biogeography of microorganisms (smaller than 2 mm) in recent years; however, knowledge of the diversity patterns of these organisms is inadequate. The reason for this lack of knowledge is that faunistic studies of these microorganisms have not been extensive enough to cover all areas of the world. Bdelloid rotifers of 200-600 µm in size are among these microorganisms. In many countries, few studies have been conducted on bdelloid fauna thus far. With only one detailed study, Turkey can be counted as one of those countries. In this present …

The Feasibility Of Producing Adequate Feedstock For Year-Round Cellulosic Ethanol Production In An Intensive Agricultural Fuelshed, Daniel R. Uden, Robert B. Mitchell, Craig R. Allen, Qingfeng Guan, Tim D. Mccoy

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

To date, cellulosic ethanol production has not been commercialized in the United States. However, government mandates aimed at increasing second-generation biofuel production could spur exploratory development in the cellulosic ethanol industry. We conducted an in-depth analysis of the fuelshed surrounding a starch-based ethanol plant near York, Nebraska that has the potential for cellulosic ethanol production. To assess the feasibility of supplying adequate biomass for year-round cellulosic ethanol production from residual maize (Zea mays) stover and bioenergy switchgrass (Panicum virgatum) within a 40-km road network service area of the existing ethanol plant, we identified ∼14,000 ha of marginally productive cropland within …

Scenarios Of Bioenergy Development Impacts On Regional Groundwater Withdrawals, Daniel R. Uden, Craig R. Allen, Rob B. Mitchell, Qingfeng Guan, Tim D. Mccoy Jan 2013

Scenarios Of Bioenergy Development Impacts On Regional Groundwater Withdrawals, Daniel R. Uden, Craig R. Allen, Rob B. Mitchell, Qingfeng Guan, Tim D. Mccoy

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Irrigation increases agricultural productivity, but it also stresses water resources (Huffaker and Hamilton 2007). Drought and the potential for drier conditions resulting from climate change could strain water supplies in landscapes where human populations rely on finite groundwater resources for drinking, agriculture, energy, and industry (IPCC 2007). For instance, in the North American Great Plains, rowcrops are utilized for livestock feed, food, and bioenergy production (Cassman and Liska 2007), and a large portion is irrigated with groundwater from the High Plains aquifer system (McGuire 2011). Under projected future climatic conditions, greater crop water use requirements and diminished groundwater recharge rates …

Gastroscopic Evaluation Of Gastric Ulcer Syndrome In Sport Horses With Poor Performance, Mehmet Alper Çeti̇nkaya, Alper Demi̇rutku, Mahi̇r Kaya

Turkish Journal of Veterinary & Animal Sciences

Gastric ulceration is common in performance horses. More than 90% of thoroughbred horses in the training season and approximately 60% of racing horses from other disciplines have gastric ulcers. Excessive secretion of gastric acid, impairment of gastric mucosal blood flow, weakening of prostaglandin E or the gastric mucus/bicarbonate layer, and gastric emptying disorders are important factors in the onset of ulceration. In this study, 12 horses with poor performance were evaluated using gastroscopy following clinical examinations. Gastroscopy revealed ulceration in 5 horses and ulcerative lesions in 7. A daily dose of 4 mg/kg omeprazole was administered orally for 4 weeks …
