Genome-Wide Analysis Of Tnf-Alpha Response In Pigs Challenged With Porcine Circovirus 2b, C. A. Kreikemeier, T. B., K. L. Lucot, Thomas E. Burkey, Daniel C. Ciobanu
Genome-Wide Analysis Of Tnf-Alpha Response In Pigs Challenged With Porcine Circovirus 2b, C. A. Kreikemeier, T. B., K. L. Lucot, Thomas E. Burkey, Daniel C. Ciobanu
Department of Animal Science: Faculty Publications
Tumor necrosis factor alpha (TNF-α) is a pro-inflammatory cytokine with a role in activating adaptive immunity to viral infections. By inhibiting the capacity of plasmacytoid dendritic cells to produce interferon-α and TNF-α, porcine circovirus 2 (PCV2) limits the maturation of myeloid dendritic cells and impairs their ability to recognize viral and bacterial antigens. Previously, we reported QTL for viremia and immune response in PCV2- infected pigs. In this study, we analyzed phenotypic and genetic relationships between TNFα protein levels, a potential indicator of predisposition to PCV2 co-infection, and PCV2 susceptibility. Following experimental challenge with …

While visual forms of vigilance behavior and their relationship with predation risk have been broadly examined, animals also employ other vigilance modalities such as auditory vigilance by listening for the acoustic cues of predators. Similar to the tradeoffs associated with visual vigilance, auditory behavior potentially structures the energy budgets and behavior of animals. The cryptic nature of auditory vigilance makes it difficult to study, but on-animal acoustical monitoring has rapidly advanced our ability to investigate behaviors and conditions related to sound. We utilized this technique to investigate the ways external stimuli in an active natural gas development field affect periodic …

Food Science Faculty Articles and Research
Product mislabeling, adulteration, and substitution are increasing concerns in highly processed foods, including pet foods. Although regulations exist for pet foods, there is currently a lack of information on the prevalence of pet food mislabeling. The objective of this study was to perform a market survey of pet foods and pet treats marketed for domestic canines and felines to identify meat species present as well as any instances of mislabeling. Fifty-two commercial products were collected from online and retail sources. DNA was extracted from each product in duplicate and tested for the presence of eight meat species (bovine, caprine, ovine, …

Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Independent Study Project (ISP) Collection
This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.

Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham
Independent Study Project (ISP) Collection
Since time immemorial, the Lepcha people have called the Himalayan region that makes up the modern state of Sikkim their home and have held sacred the rivers, mountains, and forests that make up the biologically diverse region. Over the past two decades, India’s rapid development has generated a powerful thirst for electricity, and the country has increasingly looked to the cold, powerful rivers thundering from the Himalayas to supply that desired power. Hydroelectric projects have been proposed and implemented throughout the Himalayan region. Nowhere, however, are the dams as numerous or their effects as acutely felt as in India’s northwestern …
Investigation Of Dried Distillers Grains With Solubles (Ddgs) Susceptibility To Red Flour Beetle (Tribolium Castaneum (Herbst)) Infestation, Mahsa Fardisi
Open Access Dissertations
Protecting livestock feed from insect infestation is a common challenge that feed facility managers and farmers have to deal with. It becomes an issue of importance because insect infestation degrades feed quality and quantity. Dried Distillers Grains with Solubles (DDGS) is added to livestock feed because of its high protein content. As DDGS usage in animal feed increases, understanding the susceptibility of DDGS, when mixed with livestock feed, to insect infestation is necessary for safe feed storage. This research addressed four questions. The first looked at the susceptibility of DDGS, when stored as a raw ingredient, to Tribolium castaneum (Herbst) …
Propionate Induces Gluconeogenesis In Dairy Cattle Through Direct Activation Of The Bovine Cytosolic Phosphoenolpyruvate Carboxykinase Gene Promoter, Qian Zhang
Open Access Dissertations
Phosphoenolpyruvate carboxykinase (PCK, GTP; EC4.1.1.32) catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), a critical reaction for gluconeogenesis. The two isoforms of PCK, namely cytosolic PCK (PCK1), and the mitochondrial PCK (PCK2) are abundantly expressed in liver and kidney. Increased PCK1 activity and mRNA expression in liver is observed as feed intake recovers during early lactation in dairy cows, a condition linked to increased ruminal propionate production. The central hypothesis of this dissertation is that propionate regulates its own metabolism in liver of dairy cattle through regulation of the PCK1 gene. The objectives of this dissertation were to determine: …

A Comparison Of The Genetic Diversity Of The Class Ii Major Histocompatibility Complex In Ex Situ And In Situ Populations Of African Penguins (Spheniscus Demersus), Emily Willmer
Undergraduate Honors Thesis Projects
As an endangered species, the African penguin (Spheniscus demersus) is at risk of becoming extinct in the wild due to destruction of their coastal habitat and reduction in food availability. The development of a genetically diverse and healthy captive population is important in helping to conserve the species. The goal of this project was to determine the genetic diversity of the class II major histocompatibility complex (MHC) of a wild population of African penguins and compare it to the diversity of the captive population at Mystic Aquarium in Mystic, Connecticut that has previously been studied. We found that …

Natural Resource Management Faculty Publications
In South Dakota, breeding giant Canada geese (Branta canadensis maxima) have increased substantially, and harvest management strategies have been implemented to maximize hunting opportunity (e.g., special early-September seasons) on local, as well as molt-migrant giant Canada geese (B. c. interior) while still protecting lesser abundant Arcticbreeding Canada geese and cackling geese (e.g., B. hutchinsii, B. minima). Information on important parameters, such as survival and recovery rates, are generally lacking for giant Canada geese in the northern Great Plains. Patterns in Canada goose band recoveries can provide insight into the distribution, chronology, and harvest pressures to which a given goose population …

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-Wildlife Conflict In Selela Village, Nicole Chlebek, Laura Stalter
Independent Study Project (ISP) Collection
The beastly journey of long-distance migration for the African Elephant (Lexodonta Africana) is important for upholding their connections between diminishing protected areas, especially in northeastern Tanzania. However, human development is encroaching into these corridors, creating a human-elephant conflict, which can ruin livelihoods of villagers, depending on the extent of conflict. This study focused on exploring the hypothesized human-elephant conflict on the Selela corridor, specifically in Selela village, as well as GPS (Global Positioning System) mapping evidence of elephant travel along the projected Selela elephant corridor connecting Ngorongoro Conservation Area (NCA), to Selela Forest Reserve (SFR), and finally to Manyara Ranch. …

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski
Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski
Independent Study Project (ISP) Collection
Due to their extreme variations in condition over the course of a day, intertidal zones are challenging environments. Organisms that live there must be prepared to cope with both exposure and submersion, not to mention the temperature variations that accompany these conditions. The differing tolerances and adaptations of various organisms to these conditions generally cause patterns of vertical zonation to occur in the intertidal zone, especially when the shore is steep and rocky. Understanding the ecology of shore environments is important to future conservation and management efforts. This study was conducted on a beach in Mangapwani, Zanzibar at at 6˚ …
Non-Compliance In Marine Reserves: Measuring The Drivers Of Behavior Among Recreational Fishermen Within The Great Barrier Reef Marine Park, Nick Manning
Independent Study Project (ISP) Collection
The Great Barrier Reef Marine Park (GBRMP) provides outstanding ecological, cultural, social, and economic services to the number of communities that use it. Most of the park is regulated via a zoning system designed to protect its biodiversity and ensure the sustainable use of its resources (GBRMPA, 2004). Like any social institution, zoning regulations rely heavily on compliance in order to be effective. Recreational fishing on the GBRMP accounts for most of the noncompliance behavior associated with zoning (Arias and Sutton, 2013). Thus, understanding fishers compliance behavior is central to understanding how to best manage these areas. Using results from …

Historical And Contemporary Demography Of Leaf-Toed Geckos (Phyllodactylidae: Phyllodactylus) In The Mexican Dry Forest, Christopher Blair, Victor H. Jiménez Arcos, Fausto R. Méndez De La Cruz, Robert W. Murphy
Publications and Research
Disentangling the relative influence of historical versus contemporary processes shaping the spatial distribution of genetic variation is critical if we are to effectively mitigate key biodiversity issues. We utilize a comprehensive approach based on different molecular marker types and analytical methods to understand the demographic consequences of recent habitat fragmentation in a spatially explicit context. We focus our efforts on native leaf-toed geckos (Phyllodactylus tuberculosus saxatilis) throughout fragmented habitat in the tropical dry forest of northern Mexico as recent evidence suggests that geographic ranges for these geckos may be much smaller than currently realized. However, no data are …
Experimental Shifts In Intraclutch Egg Color Variation Do Not Affect Egg Rejection In A Host Of A Non-Egg-Mimetic Avian Brood Parasite, Rebecca Croston, Mark E. Hauber
Experimental Shifts In Intraclutch Egg Color Variation Do Not Affect Egg Rejection In A Host Of A Non-Egg-Mimetic Avian Brood Parasite, Rebecca Croston, Mark E. Hauber
Publications and Research
Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest. In systems where parasitic eggs mimic host eggs in coloration and patterning, extensive intraclutch variation in egg appearances may impair the host’s ability to recognize and reject parasitic eggs, but experimental investigation of this effect has produced conflicting results. The cognitive mechanism by which hosts recognize parasitic eggs may vary across brood parasite hosts, and this may explain variation in experimental …
Spatial And Temporal Relationships Between Forest Bird Declines And Prevalence Of The Hemlock Woolly Adelgid In The Northeastern United States, Julie E. Blum, Andrew M. Wilson
Spatial And Temporal Relationships Between Forest Bird Declines And Prevalence Of The Hemlock Woolly Adelgid In The Northeastern United States, Julie E. Blum, Andrew M. Wilson
Student Publications
The eastern hemlock (Tsuga canadensis) is a vital foundation tree species throughout the eastern United States, providing essential structural diversity and habitat for more than 120 different animal species. Within the past few decades, T. canadensis has undergone significant declines that are largely associated with the hemlock woolly adelgid (HWA; Adelges tsugae), an exotic, aphid-like insect native to East Asia. From the 1970s to present day, the HWA has spread throughout southern New England, large portions of the Mid-Atlantic region, and parts of Tennessee and the Carolinas. Research has shown that loss of the eastern hemlock is …

A Feasibility Study Of Using Unmanned Aerial Vehicles To Survey Avian Abundance By Using Audio Recording, Janine M. Barr, Andrew M. Wilson
Student Publications
Roadside counts are commonly used to assess songbird abundance, but they result in oversampling habitat edges and underrepresenting core habitats, areas of steep terrain, and wetlands. Accessing off-road habitats can be logistical challenging and time-consuming, resulting in low survey efficiency. Aerial ecological surveys, using unmanned aerial vehicles (UAVs, or drones) have already proven to be valuable in wildlife monitoring. Previous studies have used photography or videography to provide permanent documentation of wildlife surveys through low altitude aerial imagery. A significant advantage of UAVs over manned aircraft is their greater safety and lower costs. We propose that UAVs can also be …

The Behavioral Causes Of Reproductive Skew In Cooperatively Polygynandrous Acorn Woodpeckers (Melanerpes Formicivorus), Anna C. Brownson
The Behavioral Causes Of Reproductive Skew In Cooperatively Polygynandrous Acorn Woodpeckers (Melanerpes Formicivorus), Anna C. Brownson
Biological Sciences Theses & Dissertations
Reproductive skew, the degree to which reproduction is shared among same-sex individuals in a social group, is a pattern affected by ecological conditions, sociality, cooperation, and the inter- and intrasexual behavior of individuals in complex animal societies. Transactional and compromise skew models assume that high skew is the product of dominance hierarchies among cobreeders, yet this has rarely been tested. Both model types fail to incorporate the decisions of more than two individuals, generally overlooking the effect of female behavior on male reproductive success in multi-male groups, and are ineffective at predicting skew in larger groups characterized by more than …

Age Determination Of Modern And Archaeological Chinook Salmon (Oncorhynchus Tshawytcha) Using Vertebrae, Anthony Raymond Hofkamp
Age Determination Of Modern And Archaeological Chinook Salmon (Oncorhynchus Tshawytcha) Using Vertebrae, Anthony Raymond Hofkamp
Dissertations and Theses
Incremental growth rings in X-rays of salmon vertebrae have been used since the 1980s to age Pacific salmon (Oncorhynchus spp.) remains from archaeological sites in the Pacific Northwest. These age estimates, paired with generalized life history patterns, have been used to determine salmon species, season of capture and in turn season of site occupation. This approach relies on a variety of assumptions, the most fundamental of which is that rings represent true years. Archaeologists using vertebral age determination techniques have failed to adequately test this assumption and present their methodologies. This thesis assesses the validity of using incremental …

Sex-Specific Foraging Habits And Roost Characteristics Of The Evening Bat (Nycticeius Humeralis) In An Intensively Managed Forest In North-Central Arkansas, Daniel Ryan Istvanko
Sex-Specific Foraging Habits And Roost Characteristics Of The Evening Bat (Nycticeius Humeralis) In An Intensively Managed Forest In North-Central Arkansas, Daniel Ryan Istvanko
Student Theses and Dissertations
The synergistic effects of white-nose syndrome (WNS) and habitat destruction have caused declines in bat populations throughout eastern North America, deeming knowledge of the spatial-temporal patterns of many bat species increasingly important to conservationists. Although many studies address the roosting ecology of imperiled forest-dwelling bats, little is known about the foraging habits of more abundant, sympatric forest-dependent species. There is even less knowledge pertaining to foraging differences between male and female bats. Therefore, during June-August 2013 and 2014, I evaluated the foraging and roosting habits of the evening bat (Nycticeius humeralis) in north-central Arkansas, using radio-telemetry. Foraging range size was …

Pincer Complexes Of Diamido-Pyridine Based Ligand As Catalysts For C-Cl And C-H Bond Activation For Cross-Coupling Reactions, Yashraj Gartia
Theses and Dissertations
Pincer type ligands have received much attention, especially for their ease of synthesis employing easily available and inexpensive starting materials. Excellent thermal stability and high melting points enable these complexes to be potentially used in a range of organometallic catalysis. In recent years, the use of nitrogenous donors at the central coordinating-group position, such as pyridines, has gained much interest for their application in various organic transformation reactions. Main examples include the activation of carbon-halogen bond, carbon-hydrogen bond, activation of small molecules (CO2, N2), polymerization of alkenes, dehydrogenation reactions, and the transfer hydrogenation reaction. In this study, we synthesized pyridine …

The Status Of Fishes In The Missouri River, Nebraska: Blue Sucker Cycleptus Elongatus, Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Blue Sucker Cycleptus elongatus are a large-bodied, benthic fish that are considered an indicator species for riverine health. A combination of historic commercial fishing and anthropogenic modifications to riverine habitat led to blue suckers being listed as a candidate species for the federal threatened or endangered species list in 1993. However, they were never designated a federally protected species. Locally, Blue Suckers are currently listed as a Nebraska Natural Legacy Project’s Tier 1 species but population changes and trends have not been quantified. Therefore, the objective of this paper was to evaluate the current population status of Blue Sucker in …
