Extracellular Atp Effects On Intracellular Actin Fibrils' Location And Characteristics [Poster], Dianna Huisman, David Mcclenahan, Ali Tabei, Joseph Tibbs

Research in the Capitol

Epithelial cells lining secretory units and ducts of bovine mammary glands perform an important role in regulating movement of various macromolecules and whole cells during normal lactation and mastitis. During mastitis, host and bacterial produced substances can affect the “barrier” function of epithelial monolayers. One potential component is adenosine triphosphate (ATP). ATP likely interacts with P2X7, a purinergic receptor, in mediating some effects associated with mastitis. Bovine mammary gland epithelial cell line, Mac-T cells, were examined for cytoskeletal changes as result of P2X7 interactions. Actin cytoskeletons were stained with phalloidin and effects were examined by fluorescent microscopy. Observable increase in …

Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, Kaci Denise Rogers

LSU Master's Theses

Zona pellucida hardening is a natural process that occurs after oocyte fertilization to prevent polyspermic fertilization and to protect embryonic development. Pre-fertilization hardening of the zona pellucida however, decreases fertilization rates. Cryoprotectants have also been shown to negatively affect fertilization rates, one possible mechanism of which being through zona hardening. This experiment was conducted to determine the effect of different cryoprotectants on hardening of the zona pellucida using fresh mature bovine oocytes and vitrified mature bovine oocytes. Oocytes were post-slaughter from mixed breed cows. After collection, oocytes were randomly assigned to three cryoprotectant treatment groups: dimethyl sulfoxide (DMSO), glycerol or …

Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda

Independent Study Project (ISP) Collection

Ecuador is one of the most biodiverse places on the planet, and many of the species in the region are found nowhere else in the world. The cloud forest is particularly diverse because the mountainous terrain isolates populations and changes in elevation create a wide variety of habitats. Cerro Mayordomo is a relatively unexplored mountain in the cloud forest of Tungurahua, Ecuador. It is known to have very high levels of endemism and several new species have been discovered there, but the biodiversity of angiosperms on the mountain has never been quantified. In this study, 5x5 m quadrants were established …

Transcriptomic Response To Immune Challenge In Zebra Finch (Taeniopygia Guttata) Using Rna-Seq, Cassandra Scalf

Masters Theses & Specialist Projects

Despite the convergence of rapid technological advances in genomics and the maturing field of ecoimmunology, our understanding of the genes that regulate immunity in wild populations is still nascent. Previous work to assess immune function has relied upon relatively crude measures of immunocompetence. However, with next-generation RNA-sequencing, it is now possible to create a profile of gene expression in response to an immune challenge. In this study, captive zebra finch (Taeniopygia guttata; adult males) were challenged with bacterial lipopolysaccharide (2 mg/Kg BW; dissolved in 0.9% saline) or vehicle (0.9% saline) to stimulate the immune system. Two hours after injection, birds …

Using 3d Models And Virtual Reality To Foster Learning Of Carcass Anatomy, Renae Sieck

UCARE: Research Products

In meat science and carcass anatomy, an often-debated topic is the methodology educators should follow for effective and efficient learning of carcass anatomy among students. Many traditional learning environments utilize monolithic methods for teaching anatomy that fail to engage students or pedagogically enhance their cognitive development to the fullest potential. Access is also limited because of the need for specialized facilities’ and equipment. We are interested in understanding and measuring the success of learning tools such as Virtual Reality (VR) and 3D Visualization in student learning. Our study’s results would be useful to indicate if student attitudes and student performance …

Fishery Interaction Modeling Of Cetacean Bycatch In The California Drift Gillnet Fishery To Inform A Dynamic Ocean Management Tool, Nicholas B. Sisson

Biological Sciences Theses & Dissertations

Understanding the drivers that lead to interaction between target species in a fishery and marine mammals is a critical aspect in efforts to reduce bycatch. In the California drift gillnet fishery static management approaches and gear changes have reduced bycatch but neither measure ascertains the underlying dynamics causing bycatch events. To avoid further potentially drastic measures such as hard caps, dynamic management approaches that consider the scales relevant to physical dynamics, animal movement and human use could be implemented. A key component to this approach is determining the factors that lead to fisheries interactions. Using 25 years (1990-2014) of National …

Assessing Trade-Offs In Large Marine Protected Areas, Tammy E. Davies, Graham Epstein, Stacy E. Aguilera, Cassandra M. Brooks, Michael Cox, Louisa S. Evans, Sara M. Maxwell, Mateja Nenadovic, Natalie C. Ban

Biological Sciences Faculty Publications

Large marine protected areas (LMPAs) are increasingly being established and have a high profile in marine conservation. LMPAs are expected to achieve multiple objectives, and because of their size are postulated to avoid trade-offs that are common in smaller MPAs. However, evaluations across multiple outcomes are lacking. We used a systematic approach to code several social and ecological outcomes of 12 LMPAs. We found evidence of three types of trade-offs: trade-offs between different ecological resources (supply trade-offs); trade-offs between ecological resource conditions and the well-being of resource users (supply-demand trade-offs); and trade-offs between the well-being outcomes of different resource users …

Compositional Changes In Two Small Mammal Communities During Succession In Southeastern Virginia, Robert K. Rose, Robyn M. Nadolny, Jay Kiser, Stephen E. Rice, Heather Green Salamone, Jana Eggleston, Holly D. Gaff

Virginia Journal of Science

Changes in the composition of two small mammal communities were studied during eight and nine years of ecological succession in southern Chesapeake, Virginia. Using monthly live-trapping on grids of similar size and history since their abandonment as agricultural fields, we learned that house mice were early colonists on one grid but not the other.  Two species of herbivorous rodent and the granivorous eastern harvest mouse were numerically dominant on both grids across the study.  Some species disappeared early on one grid but persisted to the end at the other.   The two arboreal small mammals, golden and white-footed mice, were most …

In Vitro Assay Development As An Alternative To The Use Of Laboratory Animals For Measuring Clostridium Perfingens Type C Toxoid, Lauren M. Wilmes

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Clostridium perfringens type C produces beta toxin, which is a primary virulence determinate that can cause necrotic enteritis in neonatal animals. Vaccines directed against C. perfringens toxins have shown to be efficacious in preventing disease. However, the production of a commercial vaccine requires not only an efficacious antigen, but also testing methods for quantifying antigens and potency on final product. This research was undertaken to fulfill a need for the reduction in small animal usage to produce and deliver vaccines. The current testing methods are performed in vivo according to the Code of Federal Regulations number 9 (9CFR) United …

Saving Species, One Individual At A Time: Zoo Veterinarians Between Welfare And Conservation, Irus Braverman

Journal Articles

The role of zoo veterinarians has changed significantly in the last several decades, reflecting and revealing broader transformations in zoo culture, especially among North American accredited zoos. This article draws on several interviews with prominent zoo vets, as well as on regulations that pertain to their work, to highlight their current position at the nexus of animal health and welfare, on the one hand, and of species conservation, on the other hand. The transformation of zoos into conservation institutions in particular has resulted in the vets’ novel focus on the sustainability of populations and their intensified involvement in in situ …

Supplementation And Reproductive Strategies For Beef Females As Part Of A May-Calving Herd In The Nebraska Sandhills, Alicia Caitlin Lansford

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

The objective of these 4 studies was to evaluate the effects of management decisions on reproductive performance of beef females. Experiment 1 evaluated the efficacy of a novel s.c. prostaglandin F_2a injection on estrus synchronization and pregnancy success in yearling beef heifers. Heifers receiving a 2 mL s.c. injection of Lutalyse HighCon had similar estrus response and pregnancy rates compared to 5 mL Lutalyse i.m. within 2 different estrus synchronization programs. In experiment 2, May-calving heifers and primiparous cows were allotted to receive either no supplementation or supplement (0.45 or 0.91 kg/d per animal, heifers or primiparous cows, …

Construction Of A Pen-Scale Methane Collection System And Dietary Strategies For Methane Mitigation From Growing And Finishing Cattle, Thomas M. Winders

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

Methane production from ruminants has been researched for many years because it has a global warming potential 25x that of carbon dioxide, meaning that mitigating smaller amounts of methane can have a large environmental impact. Research has focused on individual animal methane measurements, but the literature lack in industry-scale measurements. For that reason, the methane barn was built to evaluate dietary strategies on pens of cattle rather than on individual animals. In order to test the methane barn capabilities, an experiment designed to produce differences in methane production was conducted. Cattle received the same growing diet, at either ad-libitum access …

Prediction Factors For Release Of Wildlife At A Midwestern Rehabilitation Facility, Abigail E. Smith

Undergraduate Honors Thesis Projects

Wildlife rehabilitation is a large and internationally known field with thousands of rehabilitators around the world. Resources, such as time and money, are extremely limited in rehabilitation facilities and not all animals are candidates for release due to injuries or illnesses that make them unlikely to survive in the wild. Understanding what factors predict release would be useful in focusing limited resources, but there has been little investigation previously. The purpose of this study is to determine what factors affect the survival of mammals and birds at an American Midwest wildlife rehabilitation center. It was found that animals admitted with …

Bird Population Changes Following The Establishment Of A Diverse Stand Of Woody Plants In A Former Crop Field In North Dakota, 1975– 2015, Lawrence D. Igl, Harold A. Kantrud, Wesley Newton

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Changes in the coverage of trees and shrubs on the North Dakota landscape since Euro- American settlement have likely had a pronounced impact on bird species that favor woody vegetation. Long- term data sets on breeding bird populations in wooded habitats in North Dakota or in the Great Plains are scarce. In 1975 a wildlife habitat plot was established in a 10.5 ha cropland field with a long history of small- grain production. Th e objective of this article is to evaluate the successional changes in bird populations as the habitat at this site became more biologically and structurally complex …

The Effect Of Hypoxia On The Nervous System Of Aplysia Californica, Victor Escalona, Lynne Annette Fieber, Joseph Serafy

2018 Entries

The intertidal zone of California’s Pacific coast is home to the marine snail known as Aplysia californica, an organism that has found use as a model in experiments focused on understanding the basis of learning and memory. Its simple nervous system consisting of easily identifiable neurons, its life span of a year, and a readily-accessed aquacultured source from the National Resource for Aplysia make it an excellent model for ontogenetic, neural, and behavioral studies. Here, however, the focus was on strategies this species uses to survive in an environment rife with risks of hypoxia and desiccation during the tidal …

Uvb Avoidance In Dendrobates Azereus Tadpoles, Matthew Sturtevant, Lee Kats, Agustin Vargas, Arthur Garnica

Seaver College Research And Scholarly Achievement Symposium

Most frogs are nocturnal, but dart frogs (Dendrobatidae) are diurnal and lack scales or hair that would protect them from UVB rays. Previous studies have demonstrated that adult dart frogs avoid UVB light. The purpose of this experiment was to test whether dart frog larvae would avoid UVB light when compared to local nocturnal treefrog larvae. For the experiment we used tadpoles of Dendrobates azureus and Pseudacris regilla. The tadpoles were put in tubs with a submerged shelter and exposed to 3 lighting conditions: UVB, no light and visible light. The tadpoles were exposed to only one lighting condition …

Whence And Whither: Acoustic Variability And Biogeography Of Tarsiers In North Sulawesi, Olivia Clare Kulander

Dissertations and Theses

The morning duet calls of eastern tarsiers (Tarsius spp.) in North Sulawesi were recorded and analyzed to examine the effects of geography and geologic history on their call structure. Tarsius species exhibit interspecifically variable duet calls shown to correlate with species differentiation and distribution. They are distributed across Sulawesi, a biogeographically complex island in the Indonesian archipelago, where tectonic activity and multiple glaciations during the Pleistocene generated and modified barriers to their dispersal and gene flow.

Recordings were made at ten locations from November of 2012 through June of 2014. Two locations were categorized as mainland, while eight island …
