Turkish Journal of Veterinary & Animal Sciences
Twenty-four male lambs (24.93 ± 0.93 kg) were used in order to evaluate the effects of chromium methionine (Cr) supplementation in high-energy finishing diets on the carcass characteristics and chemical composition of the longissimus muscle (LM). Treatments were 0.00, 0.60, 1.20, and 1.80 mg Cr/lamb daily. The experiment lasted 56 days. There were no effects of treatments on dry matter intake, feed to gain ratio, and final weight, which averaged 35.24 ± 1.01 kg. Supplemental Cr linearly decreased fat thickness enough to improve the estimated yield grade from 1.82 to 1.42 with no effect on the other carcass traits measured. …
Influence Of Individual Or Mixed Cellulase And Xylanase Mixture On In Vitro Rumen Gas Production Kinetics Of Total Mixed Rations With Different Maize Silage And Concentrate Ratios, Mona Mohamed Mohamed Yasseen Elghandour, Ahmed Eid Kholif, Ofelia Márquez-Molina, José Fernando Vázquez-Armijo, Anil Kumar Puniya, Abdelfattah Zeidan Mohamed Salem
Influence Of Individual Or Mixed Cellulase And Xylanase Mixture On In Vitro Rumen Gas Production Kinetics Of Total Mixed Rations With Different Maize Silage And Concentrate Ratios, Mona Mohamed Mohamed Yasseen Elghandour, Ahmed Eid Kholif, Ofelia Márquez-Molina, José Fernando Vázquez-Armijo, Anil Kumar Puniya, Abdelfattah Zeidan Mohamed Salem
Turkish Journal of Veterinary & Animal Sciences
This study assessed the effects of cellulase, xylanase, and their mixture (1:1, v/v) on in vitro rumen fermentation of five mixed rations with different maize silage (F) to concentrate (C) ratios (0F:100C, 25F:75C, 50F:50C, 75F:25C, 100F:0C). Samples were incubated using rumen inoculum from Brown Swiss cows fed ad libitum a total mixed ration of concentrate and alfalfa hay (1:1). Gas production (GP) was recorded after 2, 4, 6, 8, 10, 12, 24, 36, 48, and 72 h of incubation. Interaction effects (P < 0.0001) were observed between type of ration and enzyme for discrete lag time prior to GP. Ration type affected asymptotic GP (linear and quadratic, P < 0.0001) and in vitro GP at 24 h onward. Moreover, rations affected pH (linear and quadratic, P < 0.0001), dry matter degradability (quadratic, P = 0.05), metabolizable energy (linear, P = 0.038), short-chain fatty acids (linear, P = 0.0005), gas yield from truly digested dry matter at 24 h (linear, P = 0.0026), and microbial crude protein yield (linear, P = 0.0264). The most effective rations for in vitro GP during different times differed between different measured parameters. Enzyme administration was more effective when the ratio of maize silage was increased.

Turkish Journal of Veterinary & Animal Sciences
The monomorphism of newly hatched chicks is a major hurdle for poultry farmers at the time of sexing. The traditional sexing techniques are inaccurate and time-consuming. Therefore, the present study aimed to develop a loop-mediated isothermal amplification (LAMP)-based sex determination method to obtain a higher separation accuracy rate as compared to conventional methods. LAMP is a simple, quick, and relatively inexpensive diagnostic tool. Genomic DNA was extracted from the blood samples of Leghorn and Korean native chicks for LAMP. Two sets of primer were designed, consisting of four isothermal amplification primers in each, to amplify the female sex-specific sequence (HUR0417) …

Effects Of Long-Term Starvation And Refeeding On Fatty Acid Metabolism-Relatedgene Expressions In The Liver Of Zebrafish, Danio Rerio, Ayşe Ölmez, Mehtap Bayir, Chunfang Wang, Abdulkadi̇r Bayir
Turkish Journal of Veterinary & Animal Sciences
A 70-day starvation was conducted to determine the effects of long-term starvation on whole-body polyunsaturated fatty acid (PUFA) composition and fatty acid metabolism-related gene expression in the liver of zebrafish, Danio rerio. The starvation period was followed by a 15-day refeeding period to test recovery of both PUFA composition and gene expression levels. It was found that n-3 PUFA and arachidonic acid levels increased during starvation and returned to normal values after refeeding (P < 0.05). Expression of seven (elovl5, fads2, cpt1-β, acox1, acadvl, fabp1a, and fabp7a) of eight total genes downregulated significantly towards the end of the starvation. As a result of refeeding, gene expression of elovl5 and ppar-α returned to the normal levels. Therefore, it was concluded that, in general, mRNA expression of genes involved in fatty acid metabolism was negatively influenced by long-term starvation (70 days); there was no direct relationship between whole-body fatty acid composition and hepatic gene expressions; and 15-day refeeding was insufficient for recovery of starvation-based metabolic losses in zebrafish.
Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra
Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra
Department of Anthropology: Theses and Student Research
This study employs geometric morphometric methods to investigate the morphology and shape change of the frontal bone for Pan troglodytes and Pan paniscus. Unlike previous work on the topic, this research analyzed morphology and ontogenetic shape change in a single bone of the cranium, namely the frontal bone. Frontal bone shape was compared between juvenile Pan troglodytes and Pan paniscus and the ontogeny of the bone was assessed in Pan paniscus infants and juveniles. Analyses were performed on frontal bone morphology with and without the browridge in order to assess the morphology of the frontal apart from influences …
Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey
Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey
Graduate Student Theses, Dissertations, & Professional Papers
Temperate grasslands are among earth’s most imperiled ecosystems. In North America, steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana, USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000-km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland specialists spanned …
The Reproductive Biology Of The Finetooth Shark, Carcharhinus Isodon, In The Northwest Atlantic Ocean, Amanda N. Brown
The Reproductive Biology Of The Finetooth Shark, Carcharhinus Isodon, In The Northwest Atlantic Ocean, Amanda N. Brown
UNF Graduate Theses and Dissertations
Shark fisheries are a multimillion dollar industry in the United States and have significant contributions both recreationally and commercially. In order to maintain this industry, fisheries must be properly managed. An understanding of life history and reproduction is crucial in order to adequately manage shark fisheries. The finetooth shark, Carcharhinus isodon, is a member of the small coastal shark (SCS) fishery complex. It is found in Atlantic waters from South Carolina to Florida and throughout the Gulf of Mexico. This species has recently come under increased fishing pressure and has previously been overfished. New data is needed in order …
Non-Lethal Methods For Assessing Reproductive Status In Bonnethead Sharks (Sphyrna Tiburo), Brenda Carol Anderson
Non-Lethal Methods For Assessing Reproductive Status In Bonnethead Sharks (Sphyrna Tiburo), Brenda Carol Anderson
UNF Graduate Theses and Dissertations
Reproductive biology is a necessary element for the management of elasmobranch fisheries. Traditionally, characterization of elasmobranch reproduction has involved lethal sampling to examine gross reproductive structures and development of embryos. However, this method is counterproductive to the conservation of shark populations. One non-lethal alternative is the measurement of serum hormones, which often vary according to reproductive events. Radioimmunoassay (RIA) has been used to measure hormone concentrations in reproductive endocrinology, but can be problematic for researchers. Alternatively, chemiluminescence immunoassays (CLIA) are routinely used for measuring circulating hormone concentrations in low-volume, non-extracted human serum samples. However these assays have not been previously …
Hitchhiking Bats On The Great Lakes Of North America, Saska E.H. Lohi
Hitchhiking Bats On The Great Lakes Of North America, Saska E.H. Lohi
Dissertations, Master's Theses and Master's Reports
Bats can act as potential vectors for various zoonotic diseases and other pathogens. Therefore their interactions with people should be examined to mitigate potential risks. Bats are small flying mammals and hide in small crevices during daylight hours, making them difficult to observe. Consequently, they have a capacity to “hitchhike” on ships to be dispersed over large distances.
This study focused on anthropogenic unintentional bat translocations, i.e. hitchhiking bats. The study area is the Great Lakes region in North America. Using a web-based questionnaire survey, I asked the public about the frequency of bat-human encounters on ships, their nature, and …
Assessing Chemical Control Of Earthworms At Airports, Thomas W. Seamans, Bradley F. Blackwell, Glen E. Bernhardt, Daniel A. Potter
Assessing Chemical Control Of Earthworms At Airports, Thomas W. Seamans, Bradley F. Blackwell, Glen E. Bernhardt, Daniel A. Potter
United States Department of Agriculture Wildlife Services: Staff Publications
Earthworms originating from Europe (e.g., Lumbricus spp., Aporrectodea spp.), which are common in the United States and southern Canada can create hazardous conditions at airports by attracting birds that pose a threat to aircraft. These nonnative earthworms are also considered pests on golf courses and sports fields, as well as having detrimental effects on temperate boreal forests. No toxicants or repellents are currently registered for earthworm control in the United States. Our purpose was to identify products that could be used to repel or suppress nonnative earthworms on airports or other managed sites where they pose a hazard or nuisance. …
The Effects Of Lampricide 3-Trifluoromethyl-4-Nitrophenol Toxicity On The Gills Of Larval Sea Lamprey And Non-Target Rainbow Trout And Lake Sturgeon, Lisa A. Sorensen
The Effects Of Lampricide 3-Trifluoromethyl-4-Nitrophenol Toxicity On The Gills Of Larval Sea Lamprey And Non-Target Rainbow Trout And Lake Sturgeon, Lisa A. Sorensen
Theses and Dissertations (Comprehensive)
The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), is widely used in the Great Lakes to control invasive sea lampreys (Petromyzon marinus) populations, but much about its sub-lethal effects remains unknown. A better understanding of its toxicity is needed to improve TFM effectiveness and to protect non-target organisms from its potential adverse effects. The objectives of this thesis were to test the following two hypotheses: (1) impairment of mitochondrial ATP production by TFM interferes with ATP-dependent ion-uptake by fish, leading to altered electrolyte balance, and (2) perturbations of gill function by TFM are exacerbated in soft, ion poor water (SW; 40 mg …
Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves
Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves
Honors Theses and Capstones
Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes. Within and among years molt can vary by time and age or by reproductive status. Past studies have found differences in molt pattern and timing depending upon age, and between captive reared and wild caught individuals. There has been little investigation into the molting characteristics of Peromyscus leucopus and P. maniculatus, specifically in comparison to adults and juveniles. I used molt observed from museum specimens …

Carnivore Diet Identification Through Scat And Genetic Analysis In Namibia, Africa, Alicia J. Walsh
Honors Theses and Capstones
Worldwide the cheetah population is declining making them Africa’s most endangered large cat. Namibia, Africa currently has the largest population of cheetahs in the world. During the summer of 2014, I did scat analysis of carnivores on the property of the Cheetah Conservation Fund (CCF) in Namibia in order to better understand the predators that compete with the cheetah and how the ecosystem works as a whole. I worked at CCF for nine weeks to analyze the diets of carnivores in the area through genetic and scat analysis. Analyzing carnivore feces would ultimately identify the diet of various carnivores in …
The Status Of Fishes In The Missouri River, Nebraska: Sauger (Sander Canadensis), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
The Status Of Fishes In The Missouri River, Nebraska: Sauger (Sander Canadensis), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Early fisheries investigation of the Missouri River fish community indicated that Sauger were common throughout Nebraska, including all major Missouri River tributaries. However due to many factors, their current range is restricted to the Missouri River and the lower reaches of a few tributaries. Hesse (1994) recommended listing Sauger as a state endangered species but this recommendation was never implemented. Therefore, the objective of this paper is to reevaluate the current population status of Sauger in the Missouri River along Nebraska’s border. Over 2,100 Sauger have been captured from the Missouri River along Nebraska’s eastern border since 2003. Sauger were …

Throughout the past century, the Missouri River has been highly modified which has negatively affected the native fish community. Previous research quantified the reduction of several native Cyprinidae species and made several recommendations to aid in recovery. However, these recommendations were not implemented. Therefore, the objective of this paper is to assess the current population trends of eight native cyprinid species and develop the current management objectives. Over 335,000 fish were collected from the Missouri River along Nebraska’s eastern border with mini-fyke nets and otter trawls from 2003 to 2012. Target Cyprinidae species consisted of less than five percent (n …

Winter Activity Of Bats In Southeastern Nebraska: An Acoustic Study, Jeremy A. White, Brett R. Andersen, Hans W. Otto, Cliff A. Lemen, Patricia W. Freeman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Many North American bats are active outside hibernacula in winter, but no information on winter activity has been reported for Nebraska. We recorded activity of bats during two winters (December-February 2012-2013 and 2013-2014) at one location in southeastern Nebraska with an acoustic detector. Bats were active throughout both winters and temperature at sunset was a good predictor of bat activity. Red bats (Lasiurus borealis) were active at our site in early December but were not recorded later in winter. We suspect these individuals were late migrants to more southern wintering sites. Big brown bats (Eptesicus fuscus) …

Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach
Theses
Contaminated sediments in marine environments have been shown to be good indicators of ecological risk and a means to assess anthropogenic impacts on marine habitats and the animals that inhabit them (Long et al. 1995, Rattner 2009). Estuarine sediments are especially complex media with regard to physical, chemical, and biological characteristics that trap, store, modify and sometimes release contaminants to the biota (Long et al. 1995). Especially vulnerable are animals that are in constant contact with the sediments, such as flatfishes that partially bury themselves for camouflage (Costa et al. 2011). Impacts can be assessed in a number of ways, …

The major histocompatibility complex (MHC) is a dynamic genome region with an essential role in the adaptive immunity of vertebrates, especially antigen presentation. The MHC is generally divided into subregions (classes I, II and III) containing genes of similar function across species, but with different gene number and organisation. Crocodylia (crocodilians) are widely distributed and represent an evolutionary distinct group among higher vertebrates, but the genomic organisation of MHC within this lineage has been largely unexplored. Here, we studied the MHC region of the saltwater crocodile (Crocodylus porosus) and compared it with that of other taxa. We characterised genomic clusters …

Student Scholar Symposium Abstracts and Posters
The intertidal zone has been described as ground zero for global warming. Here, the owl limpet, Lottia gigantea, adapted to the cool ocean temperatures, must withstand a few hours of baking sun during day-time low tides. This hardship is predicted to increase in frequency and severity in the future as the globe warms. Our research hypothesized that heat events compromise territorial behavior of L. gigantea. All observations and experiments were performed at Inspiration Point near Newport Beach, California. We measured the natural radiant temperature of tagged limpets during day-time low tides using a field-calibrated infrared “thermogun”. We also …

Successful captive-breeding and re-introduction programs must have the ability to breed a surplus of genetically suitable animals for release into the wild. Unfortunately, many individuals in captive breeding programs often do not reproduce even when they are apparently healthy and presented with genetically appropriate mates. Mate choice can affect multiple parameters of reproductive sperformance, including mating success, offspring production, survival, and fecundity. We investigated the role of mate preference and personality on the reproductive performance of male and female giant pandas (Ailuropoda melanoleuca) as measured by intromission success and litter production. We conducted these studies on giant pandas at the …

Panama is home to the greatest diversity of species in all of Central America. It is home to 174 species of frogs, 35 of which are endemic to Panama. Frogs are a vital part of many ecosystems. They maintain insect populations and act as food sources for larger predators. Their job of maintaining insect populations is essential to curbing the spread of diseases. Additionally, scientists have found chemical compounds in the skin of frogs that can be used to treat pain and prevent infections. The main threat to the majority of frogs is the deadly fungus Batrachochytrium dendrobatidis (Bd), or …

Deforestation of tropical forest for agricultural purposes threatens habitat loss of native species. The value of various agricultural landscapes in conserving avian populations is useful in determining diversity-conscious development plans. However, generalized results from regionalscale studies cannot be implemented to insular avian habitats. This study serves as the only current avian diversity study of the Chiriquí Highlands. To determine the effect of agricultural land use within an insular avian habitat, I compared avian diversity and site population similarity in Guadalupe, Chiriquí Highlands of the Talamanca Range, Panama. I hypothesized that avian diversity is greatest at forest edge followed by forest …
