Molecular And Serological Evidence For Anaplasma Infection In Yaks, Miling Ma, Zhijie Liu, Guiquan Guan, Youquan Li, Jianxun Luo, Hong Yin

Turkish Journal of Veterinary & Animal Sciences

Bovine anaplasmosis caused by Anaplasma marginale is considered to be an important disease in China; large-scale investigations have not been carried out since the 1990s, however, and whether or not yaks can be infected by A. marginale has never been investigated. In this study, 2 yaks were successfully infected by the inoculation of blood infected with A. marginale under experimental conditions. Furthermore, an investigation of 482 field serum samples from yaks using an enzyme-linked immunosorbent assay (ELISA) with the recombinant major surface protein 5 (MSP5) showed that 84.4% of the results were positive. In consideration of previously determined ecological and …

The prostate and bulbourethral glands were studied sonographically in 12 sexually mature, clinically healthy male New Zealand rabbits that were 12 months old and weighed 2.8 to 3.2 kg. The prostate complex, composed of proprostate, prostate, and paraprostate parts, was observed using prepubic ultrasonography in sagittal and transversal planes and presented a hyperechoic stroma. The bulbourethral glands were …

The Effect Of Vitamin E, Selenomethionine And Sodium Selenite Supplementation In Laying Hens, Alia Aljamal

Department of Animal Science: Dissertations, Theses, and Student Research

In trial 1, 3 levels of dl-α-tocopheryl acetate (0, 50, 100 IU/kg), and 3 levels of supplemental sodium selenite (SS) (0, 0.25, 0.50 ppm), were added to a corn-soybean meal basal diet to evaluate their effects on egg quality variables, and deposition in egg yolk.  Adding 50 IU/kg dl- α-tocopheryl acetate in the diet lowered aged yolk pH.  Alpha-tocopherol in yolks increased with increasing vitamin E.  As Se level increased in the diet, yolk Se content increased.  There was a vitamin E by Se interaction affecting yolk Se content, but the highest level of Se in the yolk achieved when …

A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph

Biology Faculty Publications

Rodent pups of many species emit both ultrasonic vocalizations (USVs) and calls spanning into a lower frequency range, audible to humans (AUDs), yet there has been little systematic comparison of these different call types, or analyses of how they might differ in signal function. Here the spectral and temporal characteristics of USV and AUD pup calls are described for the prairie vole (Microtus ochrogaster), a model used in studies of monogamous mating and biparental care, and a species with an unusually large functional and anatomical representation of auditory cortex. Findings provide a detailed description of each call type, …

Estimation Of Short-Term Tag-Induced Mortality In Horseshoe Crabs Limulus Polyphemus, Jennifer Mattei, Mark Beekey, H. R. Potter, C. S. Bond, Alyssa Woronik, J. A. Roberts, K. A. Smith

Biology Faculty Publications

Horseshoe crabs Limulus Polyphemus range along the East Coast of the United States and over 150,000 of them have been marked with U.S. Fish and Wildlife Service disk tags. It has been assumed that the tags do not harm the animals and are similar to common epibionts often found on the shells of the horseshoe crabs. We investigated whether newlv tagged adult female horseshoe crabs would exhibit higher short-term mortality rates than untagged adult females. All crabs were collected from a beach in Connecticut and then were transported to a laboratory for the experiment. Tagging involved drilling a small hole …

All fish were collected with boat mounted electrofishing gear, and aquatic habitat and physiochemical water quality measurements were recorded at …

Use Of Sarima Models To Assess Data-Poor Fisheries: A Case Study With A Sciaenid Fishery Off Portugal, Nuno Prista, Norou Diawara, Maria J. Costa, Cynthia M. Jones

OES Faculty Publications

Research on assessment and monitoring methods has primarily focused on fisheries with long multivariate data sets. Less research exists on methods applicable to data-poor fisheries with univariate data sets with a small sample size. In this study, we examine the capabilities of seasonal autoregressive integrated moving average (SARIMA) models to fit, forecast, and monitor the landings of such data-poor fisheries. We use a European fishery on meagre (Sciaenidae: Argyrosomus regius), where only a short time series of landings was available to model (n=60 months), as our case-study. We show that despite the limited sample size, a SARIMA model could …

Question: Are there territory sizes, shapes, and movement rules that animals can use to maximize their presence for territorial and reproductive purposes? Features of the model: Individual-oriented simulation model of a focal male, a female (his mate), and six other males in adjacent territories. Simulation variables were territory size and aspect (length-to-width ratio), velocity, step size, and potential movement angle. Each simulation represented 10,000 s of real time, and simulations were repeated until convergence on maximum mean encounter rates (MER) of a focal male with the female and other males was reached. Ranges of variables: Simulations consisted of three velocities …

Evaluating Methods For Optimizing Classification Success From Otolith Tracers For Spotted Seatrout (Cynoscion Nebulosus) In The Chesapeake Bay, Stacy Kavita Beharry

OES Theses and Dissertations

Identifying the natal sources of fish is an important step in understanding its population dynamics. Adult recruits are often sourced from multiple nursery areas, with good quality locations contributing disproportionately more fish to the adult stock. Because population persistence is strongly influenced by nursery habitat, methods that correctly identify the source of recruits are necessary for effective management. Within the last decade, otolith chemistry signatures have been increasingly used as a natural marker to delineate fish from a mixture of nursery sources. Despite the widespread use of otolith trace element and stable isotope ratios as habitat markers, the statistical approaches …

Effects Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) On Energy Stores And Gill Function In Sea Lamprey (Petromyzon Marinus) And Rainbow Trout (Oncorhynchus Mykiss), Matthew Henry

Theses and Dissertations (Comprehensive)

The primary method of controlling invasive sea lamprey (Petromyzon marinus) populations in the Great Lakes is the application of the pesticide 3-trifluoromethyl-4-nitrophenol (TFM) to larval lamprey nursery streams. Recent evidence suggests that the mode of toxic action of TFM involves the inhibition of oxidative ATP production in the mitochondria. As a result, there is increased reliance on the anaerobic pathways of ATP production which involves the hydrolysis of phosphocreatine (PCr) and anaerobic glycolysis. TFM may also damage the gills, which may disrupt gill-mediated ion regulation and cause internal ion imbalances. While knowledge of TFM toxicity in larval lampreys …

Use Of Condensed Tannins Supplementation And Inorganic Copper As Deworming Agents In Naturally Infected Ewes And Lambs, Moara De Santana Martins

LSU Master's Theses

Sheep production is an important socioeconomic activity for the small producers and it can represent their primary income source. Gastrointestinal parasites have become the principal limiting factor for this industry around the world, especially because of the anthelmintic resistance phenomenon that has been increasing worldwide. The negligent use of anthelmintics has been reported as the main factor in the development of resistance. Among the parasites that infect sheep, H. contortus is considered the most harmful and also the parasite responsible for the fastest development of nematode resistance in small ruminants. Due to the economic impact this parasite may bring upon …

Using Archaeological Fish Remains To Determine The Native Status Of Anadromous Salmonids In The Upper Klamath Basin (Oregon, Usa) Through Mtdna And Geochemical Analysis, Alexander E. Stevenson

Dissertations and Theses

Within the Upper Klamath Basin, Oregon, the native status of anadromous salmonids (Oncorhynchus spp.) has been a long standing question. Ongoing efforts to establish if these fish were native to the region prior to the construction of the Copco I Dam on the Klamath River (c.1917) have relied on sparse, contradictory and sometimes unreliable historic documentation and informant testimony. Current restoration projects with very high financial and social costs necessitate accurate and reliable data on salmonid species which once called the region home. Often, archaeolofaunal remains present a novel way to determine species present in an area prior to …

Population Structure Of Island-Associated Pantropical Spotted Dolphins (Stenella Attenuata) In Hawaiian Waters, Sarah Shelby Courbis

Dissertations and Theses

Understanding gene flow, diversity, and dispersal patterns is important for predicting effects of natural events and anthropogenic activities on dolphin populations. With the very recent exceptions of false killer whales (Pseudorca crassidens), spinner dolphins (Stenella longirostris), and common bottlenose dolphins (Tursiops truncatus), Hawaiian odontocete species are managed as single stocks within the U.S. Hawaiian Exclusive Economic Zone. These exceptions are a result of recent studies that have indicated that some species have populations that show fidelity to individual islands or groups of islands, resulting in genetic differentiation, often with management implications. The first part …

Intravenous Injection Of Insulin For Measuring Insulin Sensitivity In Horses: Effects Of Epinephrine, Feeding Regimen, And Supplementation With Cinnamon For Fish Oil, Lisa Rosalee Earl

LSU Master's Theses

Seven experiments were performed to assess the use of glucose responses to insulin injections as a means of estimating insulin sensitivity in horses; to compare the insulin sensitivities of normal horses vs. those displaying hyperleptinemia; and to put this method into practical application. Experiment 3.1 examined dose-responses in mares of potentially different insulin sensitivities. Recombinant human insulin was injected at doses of 8, 20, 50, and 125 mU/kg BW, as needed, to estimate the dose of insulin causing a 50% decrease in glucose concentrations (ED50). Five mares each of low leptin concentrations (LL) and low BCS, LL and high BCS, …

Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon

USF Tampa Graduate Theses and Dissertations

Atlantic tarpon are sought after because of their fighting ability on various tackle and support a popular, lucrative and predominantly catch-and-release recreational fishery in Florida. They are not commercially harvested or consumed by the general public, therefore assessing effects of catch-and-release angling on tarpon survival is critical to a sustainable fishery. Tarpon caught on artificial breakaway jig and traditional live bait fishing charters in Boca Grande Pass (n=42) and trips from the recreational fishery of Tampa Bay (n=40) were tagged with ultrasonic transmitters and tracked up to 6 hours immediately following release to estimate post-release mortality. Of the 82 tagged …

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

USF Tampa Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil …

An In Situ, Individual-Based Approach To Quantify Connectivity Of Marine Fish: Ontogenetic Movements And Residency Of Lingcod, Mary Anne Bishop, Brad F. Reynolds, Sean P. Powers

University Faculty and Staff Publications

As modern fishery assessments change in an effort to be more accurate and encompass the range of potential ecosystem interactions, critical information on the ecology of species including life history, intra and inter-specific competitive interactions and habitat requirements must be added to the standard fishery-dependent and independent data sets. One species whose movements and habitat associations greatly affects exploitation patterns is lingcod, Ophiodon elongatus, which support an economically important fishery along the coastal waters of the Pacific Coast of North America. High site fidelity and limited movements within nearshore areas are hypothesized to have resulted in high catchability, a …

Climate change interacts with and can often amplify the negative impacts of invasive species. These interactions are not fully appreciated or understood. They can result in threats to critical ecosystem functions on which our food system and other essential provisions and services depend as well as increase threats to human health. The Invasive Species Advisory Committee to the National Invasive Species Council recognizes the Administration’s commitment to dealing proactively with global climate change. However, unless we recognize and act on the impact of climate change and its interaction with ecosystems and invasive species, we will fall further behind in …

The Use Of High Distillers' Grains And Nutrient Management In Beef Feedlots, Amy R. Rich

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to determine the effect of feeding wet distillers grains (WDGS) at 70% and wheat straw at 25% (DM basis) on finishing steer performance and N mass balance in open feedlot pens. Four treatments were tested as a 2x2 factorial with factors being diet and pen cleaning frequency (monthly or at the end of the feeding period). In both experiments the CON treatment (corn based diet) had greater DMI, ADG, HCW, marbling and fat depth. There was greater N intake and N excretion for both the WINTER and SUMMER experiments on the WDGS. Not all the additional …

Controlling The Mineral Content Of Sweet Whey Powder In An Industrial Setting, Matthew W. Sawyer

Dairy Science

The objective of this project was to reduce the final ash content of sweet whey powder. The data for this project was collected over a two-week period, from July 13th to July 27th 2010 in a dairy plant in the Mid-West of the United States. The data is composed of particle size test, ash test, and pH test. The conclusions of this study are that multiple pre-heat treatment tank changes contribute to mineral content by requiring more buffering than usual. The low pH of this pre-heat liquid forces a need for more buffering. Particle segregation may play a role in …

Fisheries-Dependent Indicators Of Climate Change In Western Australia Wamsi:Sub-Project 4.2.3, Nick Caputi, Alan Pearce

Fisheries Research Reports

The use of fishery-dependent data may be a cost-effective way of assessing whether there have been any changes in the distribution and relative abundance of species. Such indicators are part of an ongoing data gathering system and the costs are relatively low compared to those of a fishery-independent field program. Fishery-dependent data may therefore be obtained at a higher frequency and allow detection of changes faster than would be possible from the results from the direct sampling of specific sites within entire ecosystems.

Flank Gland-Secreted Putative Chemosignals Pertaining To Photoperiod, Endocrine States, And Sociosexual Behavior In Golden Hamsters, Ying-Juan Liu, Da-Wei Wang, Lixing Sun, Jin-Hua Zhang, Jian-Xu Zhang

All Faculty Scholarship for the College of the Sciences

Behavioral studies have shown that flank glands are involved in chemical communication in golden hamsters Mesocricetus auratus but little chemical analysis has been conducted on volatiles arising from these glands. Using gas chromatography- mass spectrometry, we detected compounds from the flank glands of males, only eight of which were also produced in females. Based on these chemical data we performed a number of further experiments. By manipulating light we found that males exposed to short-photoperiods developed smaller flank glands than those exposed to long-photoperiods. Six flank gland volatiles reduced in relative abundance, which possibly coded for reproductive status of males …
