The Effects Of Hazing On Urban Coyotes, Dakota Reed
The Effects Of Hazing On Urban Coyotes, Dakota Reed
Undergraduate Honors Capstone Projects
Urban expansion has rapidly increased over the last few decades. Over half of the human population now lives in urban areas (United Nations 2014). This has resulted in many carnivores being forced to adapt and find ways to use urban resources to survive (Bateman and Fleming 2012). While larger carnivores usually end up locally extinct, some medium sized predators like red fox (Vulpes vulpes), coyotes (Canis latrans), and raccoons (Procyon lotor) thrive in urban environments (Bateman and Fleming 2012). Having these carnivores living among humans can have both positive and negative consequences for the …
Relationships Of Beef Cattle Temperament With Feedlot Performance, Jeffrey James Briscoe
Relationships Of Beef Cattle Temperament With Feedlot Performance, Jeffrey James Briscoe
Undergraduate Honors Capstone Projects
This study determined relationships between beef cattle temperament and their feedlot performance. Thirty-five Angus cross-bred steers and heifers (18 steers and 17 heifers) were placed in the Utah State University feedlot to take part in the feed trial. Cattle temperament was measured by a chute score (CS, ranging from 1 = calm and not moving to 5 = rearing and violently struggling) and flight speed. Flight speed was measured by two observers to determine how long the animal took to travel 12 feet from the exit of the squeeze chute. Feedlot performance was assessed by body weight (BW) measurements, average …
The Role Of Orexin Receptors In Diurnal Variations In Learning And Memory, Jacob Christian Blotter
The Role Of Orexin Receptors In Diurnal Variations In Learning And Memory, Jacob Christian Blotter
Undergraduate Honors Capstone Projects
The brain's ability to learn and remember is a topic of extensive debate and research. Mammals share many similarities, including the way in which information from the outside world is processed and stored. Mammalian circadian rhythms have long been thought to be essentially involved with these processes. Orexin, a neurotransmitter in the brain, plays a crucial role in arousal and circadian rhythm. This study is designed to explore the brain's ability to process and store information at different times of the circadian period, and to explore the role of orexin by comparing the performance of normal (wild-type) mice and abnormal …
Factors Of Profitable Field Crop Selection, Jacob Thomas Briscoe
Factors Of Profitable Field Crop Selection, Jacob Thomas Briscoe
Undergraduate Honors Capstone Projects
Methods of crop selection are varied, depending on a variety of factors, including resources, climate, soil type, and potential marketability of the crop. This study utilizes a theoretical farm of one thousand farmable acres to estimate the costs and returns as well as the resources associated with cultivating, planting, irrigating, harvesting and selling the crop products. The theoretical farm is situated in southwest Idaho in any of the counties of Ada, Canyon, Elmore, Owyhee and Payette. The crops grown are typical of the area; the crops examined are field corn (Zea mays), alfalfa (Medicago sativa) and …
Spa47 Is An Oligomerization - Activated Type Three Secretion System (T3ss) Atpase From Shigella Flexneri, Jamie Lee Kingsford
Spa47 Is An Oligomerization - Activated Type Three Secretion System (T3ss) Atpase From Shigella Flexneri, Jamie Lee Kingsford
Undergraduate Honors Capstone Projects
Gram-negative pathogens often use conserved type three secretion systems (T3SS) for virulence. The Shigella type three secretion apparatus (T3SA) penetrates the host cell membrane and provides a unidirectional conduit for injection of effectors into host cells. The protein Spa4 7 localizes to the base of the apparatus and is speculated to be an ATPase that provides the energy for T3SA formation and secretion. Here, we developed an expression and purification protocol, producing active Spa47 and providing the first direct evidence that Spa47 is a bona fide ATPase. Additionally, size exclusion chromatography and analytical ultracentrifugation identified multiple oligomeric species of Spa47 …
The Influence Of Prior Motor Actions On Motor Planning In Children With Autism Spectrum Disorder, Daisha Lynn Cummins
The Influence Of Prior Motor Actions On Motor Planning In Children With Autism Spectrum Disorder, Daisha Lynn Cummins
Undergraduate Honors Capstone Projects
Studies have found children with Autism Spectrum Disorder (ASD) have a rigidity of motor plans and difficulties planning and executing movements. Children with ASD also exhibit repetitive behaviors such as nail biting and rocking back and forth. When planning for movements, repetitive behaviors might manifest as difficulty in formulating new or switching between different motor plans. In typically developing individuals, actions are often influence by recently performed motor actions. We sought to determine if this influence was stronger in children with ASD.
A rotation motor task was created to evaluate the rigidity of motor planning of five children with ASD …
Using Accelerometer Data To Remotely Assess Predation Activity Of Arctic Wolves, Heather Shipp
Using Accelerometer Data To Remotely Assess Predation Activity Of Arctic Wolves, Heather Shipp
Undergraduate Honors Capstone Projects
Arctic wolves (Canis lupus arctos) play an important role in ecosystems located in the far northern regions of the world; however, unlike the gray wolves in Yellowstone National Park, little information is available about High Arctic wolves and their impacts on prey populations. This research uses data received from two GPS radio-collared Arctic wolves located in the Fosheim Peninsula on Ellesmere Island. Each radio-collar was programmed to record a position every 30-60 minutes, as well as the wolfs activity movement (forwards - backwards and left - right), which was generated by an accelerometer housed within the radio-collar. This …
The Effect Of Pure Infrared Light On The Growth Of Rhodospirrilum Rubrum, Jordan Lee Wilkes
The Effect Of Pure Infrared Light On The Growth Of Rhodospirrilum Rubrum, Jordan Lee Wilkes
Undergraduate Honors Capstone Projects
Scientists who study aquatic ecosystems quickly notice a diversity of pathways that different microbes and organisms can use to metabolize nutrients found in common ponds or pools. Competition for vital resources, such as light and inorganic minerals, allow only certain organisms to grow in certain niches within these ecosystems. Rhodospirillum rubrum is a gram negative, photosynthetic bacteria that competes for light within aquatic ecosystems in order to survive. R. rubrum is believed to specifically absorb light for photosynthesis at wavelengths in the range of infrared light. It was found that R. rubrum indeed can grow in "dark", anaerobic environments by …
