Protected areas are intended as tools in reducing threats to wildlife and preserving habitat for their long-term population persistence. Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals …

Economic Consequences Of The Wolf Comeback In The Western United States, Dana Hoag, Stewart W. Breck, Kevin Crooks, Becky Niemiec

USDA Wildlife Services - Staff Publications

Gray wolves were eradicated from most of the United States in the 1940’s but have made a comeback in parts of their historic range over the last two decades. First reintroduced into the Greater Yellowstone Ecosystem and central Idaho in the mid-1990’s, wolves have subsequently dispersed into at least 7 western states. Coloradoans became the latest state to take interest in bolstering wolf populations, as residents passed a ballot initiative in November 2020 to reintroduce a self-sustaining population of gray wolves by the end of 2023. Conflicts between people in rural areas that might incur costs (such as livestock loss) …

Tick Surveillance And Pathogen Detection In Eastern South Dakota, Holly E. Black

Honors Thesis

Tick-borne diseases threaten the health of humans, animals, and ecosystems, but surveillance efforts are lacking in some regions. Throughout 2019, 2020, and 2021, we conducted tick surveys aimed at determining the status of the black-legged tick (Ixodes scapularis), the American dog tick (Dermacentor variabilis) and the lone star tick (Amblyoma americanum) in eastern South Dakota. Each year, ticks were collected using a flagging method and identified in the lab. A subset were tested for the presence of Borrelia burgdorferi, the causative agent of Lyme disease, by polymerase chain reaction (PCR). Dermacentor variabilis was the most commonly identified tick, …

Makara Journal of Science

The color of edible bird’s nest is associated with its nitrite concentration, but this relationship remains inconclusive. This investigation aimed to evaluate the nitrite content in edible bird’s nest of four different colors: white, yellow, orange, and red blood. Fifty-eight edible bird’s nest samples were obtained from five swiftlet farmhouses in Borneo Island, Indonesia and analyzed for nitrite content using Genesys 30 visible spectrophotometer. Results showed that the dark-colored edible bird’s nests (yellow, orange, and red blood) had higher nitrite concentrations of 304, 317, and 309 ppm, respectively, compared with the white-colored one (15 ppm). Therefore, the color of edible …

Miniature Companion Pig Sedation And Anesthesia, Joseph Smith, Reza Seddighi

Faculty Publications and Other Works -- Large Animal Clinical Sciences

• Miniature companion pigs (MCP) are increasing in popularity, and as such, there is an increased need for veterinarians trained in sedation and anesthesia for the species.

• MCPs have several species-specific qualities that can complicate injectable drug administration and create challenges for inhalational anesthesia (eg, with endotracheal intubation).

• General anesthetic complications, such as hypothermia and hypotension, are commonly described in miniature companion pigs, so monitoring of vital parameters during anesthetic procedures and recovery is crucial.

Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy

Honors Theses, University of Nebraska-Lincoln

The production of livestock is composed of a variety of factors all effecting the outcome. For grazing livestock, a key factor in production is the grazing management system. Two of the most common grazing management systems are continuous grazing and rotational grazing. There has been evidence found proving benefits of rotational grazing in regard to vegetation productivity, and prevention and restoration of degraded rangeland. However, there is a lack of clear evidence on the relationship between grazing system and production metrics of livestock. Understanding this relationship can provide the necessary information for livestock producers in order to increase their production …

Assessment Of Diversity Of Antimicrobial Resistance Phenotypes And Genotypes Of Mannheimia Haemolytica Isolates From Bovine Nasopharyngeal Swabs, Hannah F. Carter, Robert W. Wills, Matthew A. Scott, Alexis C. Thompson, Randall S. Singer, John Dustin Loy, Brandi B. Karisch, William B. Epperson, Amelia R. Woolums

Papers in Veterinary and Biomedical Science

The threat of bovine respiratory disease (BRD) for cattle operations is exacerbated by increasing prevalence of antimicrobial resistance (AMR) in Mannheimia haemolytica, a leading cause of BRD. Characterization of AMR in M. haemolytica by culture and susceptibility testing is complicated by uncertainty regarding the number of colonies that must be selected to accurately characterize AMR phenotypes (antibiograms) and genotypes in a culture. The study objective was to assess phenotypic and genotypic diversity of M. haemolytica isolates on nasopharyngeal swabs (NPS) from 28 cattle at risk for BRD or with BRD. NPS were swabbed onto five consecutive blood agar plates; …

Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley

LSU Doctoral Dissertations

Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …

The Thai Journal of Veterinary Medicine

Mycoplasma bovis (M. bovis) is a pathogen that especially effects the respiratory system of cattle. We focused on the histopathological changes in the lungs caused by M. bovis because the lesions in the bronchi or bronchioles and alveoli are quite different in natural infections. Thirty-five lung samples from 2-to 12-month-old Japanese Black calves with respiratory symptoms were collected and examined for bacteria presence and pathological changes using immunohistochemistry (IHC). Using the loop-mediated isothermal amplification method, 18 of the 35 samples were found to be positive for M. bovis, which was isolated and identified. In 7 of the samples, only M. …

Comparison Of An Intra-Articular Suture Technique And A Lateral Suture Technique In Toy Breed Dogs With Cranial Cruciate Ligament Rupture, Sirun Tuek-Um, Chaiyakorn Thitiyanaporn, Phitchaya Phongwirat, Naris Thengchaisri

The Thai Journal of Veterinary Medicine

Cranial cruciate ligament rupture (CCLR) can result in inflammation, pain, lameness and osteoarthritis. Because there is no isometric point for surgical stabilization for CCLR, the anatomical replacement of the ruptured cranial cruciate ligament with synthetic material may provide better outcomes. This retrospective study compared short-term post-operative outcomes between an intra-articular suture technique and a lateral suture technique for treating CCLR in toy breed dogs. Twenty dogs with unilateral CCLR were divided into two groups. The lateral suture technique was a lateral circumfabellar tibial suture with monofilament nylon and the intra-articular suture was performed by passing a suture through the femoral …

Inflammatory Mediator Gene Expression Of The Kidneys Induced By Daboia Siamensis Venom And Its Components, Suchitra Khunsap, Sunutcha Suntrarachun, Orawan Khow, Jureeporn Noiphrom

The Thai Journal of Veterinary Medicine

Phospholipase A2 (PLA2) and metalloprotease (MP) from Daboia siamensis (Ds) venom are believed to contribute to renal tissue toxicity. Imbalance of the cytokine system induced by snake envenomation causes tissue injury and cell damage which leads to acute toxic kidney injury. A better understanding of the pathological mechanism involved in renal injury after venom administration is needed. In the present study, we aimed to investigate inflammatory mediator genes (IL-2, IL-10, TNFα, IFN, and COX-2) in mouse kidney tissue after venom injection. Quantitative real time PCR was performed to detect the cytokine gene profiles. Beta actin was used as a house-keeping …
