G-Banding Karyotypes Of Myotis Myotis (Borkhausen, 1797) And Myotis Blythii (Tomes, 1857) (Mammalia: Chiroptera) In Turkey, Nursel Aşan, İrfan Albayrak, Tarkan Yorulmaz, Si̇nan İnci̇

Turkish Journal of Zoology

This study is based on the G-banding karyotype of 2 sibling bat species Myotis myotis (Borkhausen, 1797) (Greater Mouse-eared Myotis) and M. blythii (Tomes, 1857) (Lesser Mouse-eared Myotis) distributed in Turkey. G-banding karyotypes showed that the 2 taxa possessed identical G-banded chromosome arms. It was concluded that G-banded chromosomes are not sufficient as a diagnostic character for separating M. myotis from M. blythii.

Use Of Copper Sulfate To Control Haemonchus Contortus Infestation In Hampshire Ewes, Melinda Mallory Simpson

University of Kentucky Master's Theses

Two studies were conducted to evaluate the effectiveness of using copper sulfate (CuSO₄) as a drench in Hampshire ewes to control stomach worms (Haemonchus contortus).

A study was conducted to assess the effectiveness of CuSO₄ to control gastrointestinal nematodes (GIN) over a three year period. Ewes were FAMACHA scored, hematocrit evaluated for packed cell volume (PCV), and fecal egg counts (FEC) were determined from 2007 through 2009. Ewes received only CuSO₄ to control GIN. Ewes with FEC exceeding 6,000 eggs/g feces were drenched.

A separate study during the summer of 2008 assessed the potential …

The Effects Of Nutritionally‐Modulated Prepartum Bcs On Pre‐ And Postpartum Metabolic Responses, In Vitro Lipid Metabolism And Performance Of Multiparous Beef Cows, Melissa Dale Hudson

University of Kentucky Doctoral Dissertations

Increased BCS at calving due to nutritional manipulation during the prepartum period resulted in greater mobilization of body fat after calving, regardless of plane of nutrition during the last 60 d of gestation. Although fatter cows were shown to have greater mobilization of reserves during the postpartum period, they maintained greater BCS at all points from calving to weaning compared to cows calving with fewer reserves at calving. A unique finding of this experiment was that the variation in BCS at calving was positively associated with BCS loss for cows fed to accrete BC during the prepartum period but was …

Department of Animal Science: Faculty Publications

Three experiments were conducted to evaluate nutrient content and DM determination methods of dry milling byproducts. In Exp. 1, nutrient composition was determined for wet distillers grains plus solubles (WDGS) and modified distillers grains plus solubles (MDGS) from 6 ethanol plants with 10 samples collected per day, across 5 d, and sampling was repeated over 4 separate months. Mean composition was 31.0% CP, 11.9% fat, 0.84% P, and 0.77% S (DM basis). Coefficients of variation for DM content were greater for some plants than others, and variation occurred within and across days. Variability was small for CP and P, whereas …

Composting Or Stockpiling Of Feedlot Manure In Nebraska: Nutrient Concentration And Mass Balance, Matt K. Luebbe, G. E. Erickson, T. J. Klopfenstein, Matthew A. Greenquist, J. R. Benton

Department of Animal Science: Faculty Publications

When feedlot pens are scraped in the spring and summer, manure is often stored before land application can occur in the fall. Manure stockpiled or composted was evaluated for nutrient losses in 2 experiments for 104 (Exp. 1) and 111 d (Exp. 2). Stockpiles (n = 2 in Exp. 1 and n = 3 in Exp. 2) and compost windrows (n = 6 in Exp. 1 and n = 4 in Exp. 2) were constructed with feedlot manure scraped from pens and sampled upon construction and throughout the storage period. In Exp. 1, N loss was 3 times greater (P < 0.01) for compost compared with stockpile on d 104 (43.6 and 14.3%, respectively). Loss of C was 34.7% greater (P < 0.01) for compost compared with stockpile on d 104 (54.4 and 40.4%, respectively). Total mass loss (water + DM) was not different (P = 0.30) among storage methods on d 104 (20.0 and 15.8% for compost and stockpile, respectively). In Exp. 2, N loss from compost was 42.1% greater (P < 0.01) compared with stockpiling on d 111. Carbon losses in Exp. 2 were not different (P = 0.77) among storage methods on d 111 (38.4 and 37.5% for compost and stockpile, respectively). Total mass loss in Exp. 2 was less compared with Exp. 1 and was not different (P = 0.23) among storage methods (5.7 and 3.6% for compost and stockpile, respectively). When evaluated on a nutrient basis, stockpiled manure had greater N and C concentrations compared with composted manure.

Use Of Modified Cages Attached To Growing Calves To Measure The Effect Of Stable Flies On Dry Matter Intake And Digestibility, And Defensive Movements, L. A. Schole, D. B. Taylor, D. R. Brink, K. J. Hanford

Department of Animal Science: Faculty Publications

The effects of stable flies on growing calves were examined using fly cages attached to the animals. Dry matter intake, DM digestibility (DMD), and behavioral responses of calves were monitored. Nine Holstein calves were exposed to 3 levels of stable flies (0, 10, 100 flies/animal) 3 times daily for 30 min. The study consisted of a 4-period crossover design; each period included 5-d adaptation, 7-d exposure, and 5-d postexposure. Calves were weighed at the beginning and end of each period. Feed consumption was continuously recorded. Fecal samples taken during and after exposure were used to determine DMD. Three calves were …

Heifer Development Systems: A Comparison Of Grazing Winter Range Or Corn Residue, D. M. Larson, Andrea S. Cupp, Richard N. Funston

Department of Animal Science: Faculty Publications

Two experiments at 2 Nebraska locations evaluated effects of heifer development system on growth and pregnancy rate. In Exp. 1, heifers (n = 270, BW = 225 ± 2 kg) grazed winter Sandhills range (WR) or west central Nebraska corn residue (CR) with a supplement (0.45 kg/animal; 31% CP; 80 mg·animal⁻¹·d⁻¹ of monensin). In Exp. 2, heifers (n = 180, BW = 262 ± 3 kg) grazed eastern Nebraska WR or CR with a supplement (0.45 to 0.90 kg/d; 31% CP; 80 to 160 mg·animal⁻¹·d⁻¹ of monensin). The CR heifers tended to have less …

A Supermatrix Analysis Of Genomic, Morphological, And Paleontological Data From Crown Cetacea, Jonathan H. Geisler, Michael R. Mcgowen, Guang Yang, John Gatesy

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Cetacea (dolphins, porpoises, and whales) is a clade of aquatic species that includes the most massive, deepest diving, and largest brained mammals. Understanding the temporal pattern of diversification in the group as well as the evolution of cetacean anatomy and behavior requires a robust and well-resolved phylogenetic hypothesis. Although a large body of molecular data has accumulated over the past 20 years, DNA sequences of cetaceans have not been directly integrated with the rich, cetacean fossil record to reconcile discrepancies among molecular and morphological characters.

Results

We combined new nuclear DNA sequences, including segments of six genes (~2800 …

The Effects Of Sexed Semen On Embryonic Development To The Blastocyst Stage, William E. Plummer, D. Beckett, A. Schaffner, B. Layport, J. Norman, C. Grimbleby, P. Wessinger, E. Pace, L. Kirscher, K. Matthews, T. Dorshorst

Animal Science

Sexed semen (SS) exhibits approximately 80% of the fertilizing ability of conventional semen (CS), and studies have shown that this continues through the 8-cell stage of bovine embryo development. At the time of this study, no information could be found that, when used for IVF and intracytoplasmic sperm injection (ICSI) development, had been carried to the blastocyst stage. In addition, questions have arisen regarding which of the measured sperm parameters are responsible for the difference between the SS and CS and contribute to this decline in fertility. The goals of this project were to evaluate the effects of using sexed …

Angler Survey Of The Connecticut River, Justin P. Davis

EEB Articles

The Connecticut River is the largest and most diverse inland fishery resource in the State of Connecticut. Significant improvements in water quality over the past 30 years have led to progressive increases in recreational use, presumably increasing fishing pressure on some species and possibly decreasing overall fishing quality. To address this concern, the Inland Fisheries Division (IFD) of the Connecticut Department of Energy and Environmental Protection (CT DEEP) conducted an angler survey on the entire portion of the Connecticut River within the state during March-October of 2008-09. The survey used a similar design as a smaller-scale survey of the river’s …

Developing Mechanisms For The Transfer And/Or Adjustment Of Rock Lobster Shares Between Sectors In Western Australia And South Australia Frdc Project No. 2007/050, Chris Reid, Western Australian Department Of Fisheries

Fisheries management papers

The purpose of this report has been to investigate potential reallocation mechanisms for the transfer and/or adjustment of catch shares between sectors and the requirements to allow for their implementation, with particular reference to their application in the Western and South Australian rock lobster fisheries. While the report focuses on the commercial and recreational sectors of these fisheries, potentially all non-commercial fishing sectors could be included under a given mechanism in the same manner as that outlined for the recreational sector, subject to the appropriateness of allowing the sector’s allocation to be transferable.

A Review Of Interior Least Tern And Piping Plover Management, Conservation, And Recovery On The Lower Platte River, Nebraska, Mary Bomberger Brown, Joel G. Jorgensen, Sonya E. Steckler, Melissa J. Panella, W. Ross Silcock

School of Natural Resources: Faculty Publications

SUMMARY

The Lower Platte River in eastern Nebraska provides many resources for wildlife and a variety of stakeholders. This river and its major tributaries contain important nesting habitat for two state and federally-listed bird species, the Interior Least Tern (endangered; Sternula antillarum athalassos) and the Northern Great Plains Piping Plover (threatened; Charadrius melodus). Both species nest on bare or sparsely-vegetated expanses of sand in natural and human-created habitat, which occur in and along river channels; the Lower Platte River system is critical for the survival and recovery of both species.

The Lower Platte River in eastern Nebraska provides …

Systematic Revision Of The Northern Short-Tailed Shrew, Blarina Brevicauda (Say), Wm. David Webster, Nancy D. Moncrief, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Short-tailed shrews, genus Blarina, are common inhabitants of a variety of terrestrial habitats in most of eastern North America. Of the 4 species currently recognized, the northern short-tailed shrew, Blarina brevicauda (Say, 1823), is the most widely distributed, occurring from southern Canada southward to the central Great Plains and the Appalachian Mountains into Georgia and Alabama and along the East Coast as far south as southeastern North Carolina. It has been more than 65 years since geographic variation within this species has been studied. Accordingly, the objectives of this study were to examine geographic variation in Blarina brevicauda and …

Ojibwe And Canis Lupus : Cultural, Historical, And Political Influences On Contemporary Wolf Management In The Great Lakes Region, Caitlin Williamson

Lawrence University Honors Projects

My thesis examines the relationship between the Ojibwe and the gray wolf (Canis lupus) by examining the historical, cultural, and political contexts that have shaped how Ojibwe currently view the wolf. I compare this relationship with the contemporary management of the wolf by federal and state governments. I conclude that the relationship between the Ojibwe and the wolf is complex, and draws on the cultural significance of the wolf to the Ojibwe, yet is also impacted by other driving factors. The Ojibwe management of the wolf contrasts with state management, and thus, Ojibwe have the opportunity to provide differing management …
