Evaluation of Bison (Bison Bison) Ecology at the Olson’s Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada
<p>Bison (Bison bison), the largest mammalian species in North America, historically numbering in the tens of millions (Roe 1970, McHugh 1972, Dary 1989, Shaw 1995), was nearly extirpated at the turn of the 19th century (Knapp et al. 1999; Gates et al. 2010). At the time, estimates of less than …

Cross-Hedging Bison with Live Cattle Futures
Bison production is an emerging retail meat industry. As demand increases, it creates opportunity for supply-side growth. However, the bison market is volatile and the potential for a drop in the value of bison makes price risk an important factor for producers. Following price risk theory, hedging …

Molecular Diagnosis and Anthelmintic Control of Trichostrongyle and Toxicara nematodes in Bison bison Herds from the U.S.A. Central Great Plains
<p>Bison producers face many challenges, including the transmission of parasitic diseases such as trichostrongylosis and toxocariasis into and within their herds. These diseases can reduce animal production and cause occasional death. There have been no surveys to identify gastrointestinal …

Evaluation of Facilities Design and Methods of Handling Bison
… for thousands of years (Diamond: 1999, 168-169). Bison (Bison bison) are not on that list even though they have been held on private ranches and in parks for over 100 years. Bison have been treated as wild, difficult to handle animals in roundups and when processing them through corrals. This …

Authentication of Species in Bison Products Using Molecular Methods
<p>American bison (<em>Bison bison</em>) meat is vulnerable to species substitution due to its high value and similar appearance to less expensive meats, such as beef from domestic cattle (<em>Bos taurus</em>). DNA barcoding of the cytochrome <em>c </em>oxidase subunit 1 (CO1) gene is a commonly …

Epidemiology of Mycoplasma bovis in farmed bison in western Canada
… is emerging as an important pathogen of farmed bison in North America, associated with high morbidity and mortality. The present work aimed to investigate the epidemiology of M. bovis-associated disease in western Canadian farmed bison. A telephone survey determined that 6% of 202 bison …

The Norby site : a mummy cave complex bison kill on the northern plains
In the summer of 1988, a Mummy Cave Complex bison kill site, was discovered on Avenue M South, Saskatoon, Saskatchewan. It was subsequently radiocarbon dated to about 5800 BP which placed the site within the Early Middle Prehistoric Period to the time of the Altithermal climatic interval. At one …

Faunal Analysis of the Tongue River Bison Kill Site (24RB2135) in Southeastern Montana
… University of Montana excavated the Tongue River bison kill site (24RB2135) in 2005 on the Northern Cheyenne Reservation. This was the site of a prehistoric bison hunt. Over 20,000 bone fragments and over 1,000 stone tools were recovered during the excavation. This study focuses on the bone …

Trouble on the Range: When Does a National Park Become a Bison Zoo?
… Park is often credited for bringing American bison back from the brink of extinction. In 1902, there were merely 25 individual bison in the park, but now, Yellowstone’s herd fluctuates between 3,000 and 5,500 animals. Over the past century, the national park’s conservation effort pushed bison …

THE BIOTRANSFORMATION OF BILE ACIDS BY A COMMON MEMBER OF THE BISON GUT MICROBIOME
… In the course of isolating and characterizing bison-associated bacteria, Arthrobacter spp. were routinely found to modify bile acids in vitro. Whole genome sequencing of a single isolate, A. citreus EINP1, revealed the presence of a bile salt hydrolase (BSH) and additional homologues with …

Gender and Conservation: A Comparative Study of the Bison and Wild Horse Conservation Movements
<p>The focus of this thesis are the American bison and wild horse conservation movements. The goal is to address how these movements utilized and manipulated gender as a driving force for conservation. Throughout the nineteenth century, bison and bison hunting became identified with American …

Modeling UO₂ and UN Fuel Fission Gas Release Instances in BISON for Microreactor Applications
… in microreactor concepts [1, 2]. As a result, BISON, a MOOSE-based (Multiphysics Object Oriented Simulation Environment) fuel performance code, was used to evaluate fission gas release in UO₂ and UN fuels at power levels representative of microreactors. The fission gas release threshold curve …
