The Effect Of Temperature On Seed Quality And Quantity In Crosses Between European (Populus Tremula) And Hybrid Aspens (P. Tremula X P. Tremuloides), L. Koviuranta, T. Latva-Karjanmaa, P. Pulkkinen

Aspen Bibliography

Hybrid aspen (Populus tremula L. Populus tremuloides Michx.) plantations are expanding in Fennoscandia and the Baltic countries; however, the possible effects of plantations on the native European aspen (P. tremula) and the level of gene flow between European and hybrid aspen have not been investigated. We studied seed quantity and quality in intraspecific and interspecific crosses of the European and hybrid aspens over a two year period. In order to study whether elevated temperatures due to climate change would benefit the species differently, we performed the crosses in different temperatures. In both years, interspecific crosses produced more seeds with higher …

Effect Of Silicon On Plant Growth And Drought Stress Tolerance, Kaerlek W. Janislampi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Silicone is a silicon-containing synthetic polymer. Silicon is a metalloid chemical element. Silicon is not considered an essential nutrient for plants, but it is typically abundant in soils and can be taken up in large amounts by plant roots. Silicon is known to have beneficial effects when added to the soil in which rice and several other plants are cultivated. These beneficial effects include disease and insect resistance, plant structural fortification, and regulation of the uptake of other plant nutrients. Silicic acid is the form of silicon in soils that is available to plants. In this study, the effect of …

Using Biophysical Geospatial And Remotely Sensed Data To Classify Ecological Sites And States, Carson A. Stam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the Intermountain West, vast expanses of big sagebrush shrubland and steppe are considered emblems of the western range. Currently, there are approximately 60 million hectares of big sagebrush within the 11 western states, four million of which are in the state of Utah. However, the historic distribution of sagebrush has been impacted by conversion to other types of land cover through juniper encroachment, urbanization, invasive weeds, and agricultural expansion. In Utah alone, big sagebrush communities have been reduced to approximately 55% of their historic extent. A primary and current example of the cumulative impact of big sagebrush loss is …

Modulation Of The Host Response To Tacaribe Arenavirus Infection In Ag129 Mice By My-24, Eric Sefing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

MY-24 is a new antiviral compound recently shown to protect immunocompromised mice from lethal challenge with Tacaribe virus (TCRV). Tacaribe virus is incapable of causing disease to humans, but is closely related to the highly pathogenic New World arenaviruses that cause often-fatal viral hemorrhagic fever syndromes. Remarkably, MY-24 prevents mortality without reducing virus burden in the circulation or tissues. To investigate the mechanism by which MY-24 protects AG129 mice against Tacaribe virus infection, we first characterized the natural history of disease in the model with an emphasis on host immune response and blood vessel function to establish the best times …

Factors Influencing Relocation Success Of Utah Prairie Dog (Cynomys Parvidens), Rachel Curtis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah prairie dogs have been extirpated in 90% of their historic range due to introduced disease, eradication, and habitat destruction. Most of the population lives on private land where animals burrow in lawns and agricultural fields, which keeps this threatened species continually in conflict with landowners. The Utah Division of Wildlife Resources has been relocating prairie dogs from private to public land since the 1970s, but relocations have been largely unsuccessful due to high mortality. Prairie dogs are highly social animals, but they are usually relocated without regard to their family group, or coterie. Coteries typically consist of one reproductive …

Population Dynamics And Movements Of Translocated And Resident Greater Sage-Grouse On Anthro Mountain, Utah, Natasha W. Gruber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Greater sage-grouse (Centrocercus urophasianus) populations have declined range-wide. Species translocations have been identified as a conservation strategy to augment declining populations in restored habitats. I evaluated protocols previously used to successfully translocate greater sage-grouse in Utah by comparing annual production, survival, habitat use, integration and seasonal movements of translocated birds and their chicks to the resident population. To conduct this study, I translocated 60 greater sagegrouse hens captured and radio-collared on Parker Mountain to Anthro Mountain in the spring of 2009 and 2010. I also captured and radio-collared 19 resident hens to serve as my control group. All …

Mechanisms And Signal Transduction Pathways Involved In Bovine Oocyte Activation, Ammon Hanson Bayles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Being able to create a genetically identical, living replicate of a prized animal sounds impossible. Through advanced scientific methods and the wonders of mother nature it can be accomplished by a process called cloning. In 2003, the USU Animal, Dairy, and Veterinary Science department and Dr. Kenneth L. White gained world wide recognition when they, along with a team for Idaho, cloned the first equine species.

Cloning certain animals could be very advantageous to the agricultural industry. Prized animals that have died could be cloned, producing the best meat and milk supply. Animals that are sterile or endangered could be …

Effects Of Slash Pile Burning After Restoring Conifer- Encroached Aspen, Christa M. Dagley, John-Pascal Berrill, Stephanie Coppeto, Kyle Jacobson

Aspen Bibliography

Removal of conifers encroaching aspen stands has been advocated and is being practiced in the Lake Tahoe Basin (EIP Project #10080: Aspen Community Restoration Projects). In remote and roadless areas, thinning of conifers is generating large volumes of wood and pile burning is currently being implemented to handle this biomass on site. However, the effects of pile burning on aspen are unknown, and there is an urgent need for guidelines to support design of thinning treatment prescriptions; specifically burn pile size and safe distances from live aspen trees of any size to prevent injury.

Multi-Stage Novice Defensive Driver Training Program: Does It Create Overconfidence?, Jessica Mueller, Laura Stanley, Kezia R. Manlove

Wildland Resources Faculty Publications

Multi-stage training programs have been recommended to transfer knowledge and skills to high-risk novice drivers. However, some have suggested there is a link between skill training and an increased crash probability due to overconfidence. This project evaluates the outcomes of a multi-phase training system and compares the performance of novice drivers who received second-stage training with that of a control group of novice drivers who received traditional, single-stage training. This trained group and an equivalent group of untrained novice drivers completed annual surveys describing their involvement with traffic citations, near-miss crashes, single-vehicle crashes, and multiple-vehicle crashes. Citation records from the …

Intrinsic Motivation, Vitality, And High Altitude Climbing: An Analysis Of Seven Case Studies, J. C. Norling, Mark F. Roark, Dale R. Wagner, A. Montour

Kinesiology and Health Science Faculty Publications

College adventure leadership programs may involve training students through multi-day expeditions to remote locations to test their physical and psychological performance. In the context of a group-oriented, mountaineering course in a high altitude environment participant's performance level might be a function of motivation level, vitality level, and/or may be influenced by physiological changes occurring during the ascent. The theoretical framework selected for the study was Cognitive Evaluation Theory (CET) (Deci & Ryan, 1985b), a sub-theory of Selfdetermination Theory (SDT) (Deci & Ryan, 1985a). CET suggests that an intrinsically motivated activity, if internalized, could be a representation of a participant's inclination …

Influence Of Aboveground Vegetation On Seed Bank Composition And Distribution In A Great Basin Desert Sagebrush Community, Kristen M. Pekas, Eugene W. Schupp

Articles

The quantity, composition, and spatial dispersion of seed banks can greatly affect community dynamics. While seed banks of hot deserts have been studied extensively, little is known about seed banks in cold deserts, in particular the relationship between the seed bank and the aboveground vegetation. We investigated the relationship between the seed bank and aboveground vegetation and the effect of microhabitat (shrub interspace or beneath shrub) and aboveground community phase (high or low perennial bunchgrass cover) on the seed bank of a Great Basin Desert sagebrush community. The seed bank and aboveground vegetation differed in their most dominant species, resulting …

Plants, Soils, and Climate Faculty Publications

The growth and physiological responses of four maize inbred lines (CUBA1, B73, B5C2, and BR1) and four sorghum hybrids (SS304, NK7829, Sordan 79, and KS585) to salinity were determined. Fifteen days after sowing, seedlings were irrigated with nutrient solution (control) at electrical conductivity (EC) of 1.5 dS m−1 or saline solution at EC of 8.0 dS m−1 (salt treatment) for 40 days. Dry weight of shoots in maize was reduced by 58%, 65%, 62%, and 69% in CUBA1, B73, B5C2, and BR1, respectively, while that of sorghum was reduced by 51%, 56%, 56%, and 76% in SS304, NK7829, Sordan79, and …

Fortification Of Cheese With Vitamin D3 Using Dairy Protein Emulsions As Delivery Systems, M. Tippetts, Silvana Martini, C. Brothersen, D. J. Mcmahon

Nutrition, Dietetics, and Food Sciences Faculty Publications

Vitamin D is an essential vitamin that is synthesized when the body is exposed to sunlight or after the consumption of fortified foods and supplements. The purpose of this research was to increase the retention of vitamin D3 in Cheddar cheese by incorporating it as part of an oil-in-water emulsion using a milk protein emulsifier to obtain a fortification level of 280 IU/serving. Four oil-in-water vitamin D emulsions were made using sodium caseinate, calcium caseinate, nonfat dry milk (NDM), or whey protein. These emulsions were used to fortify milk, and the retention of vitamin D3 in cheese curd in a …

Lawn Fertilizers For Cool Season Turf, Taun Beddes, Kelly Kopp

All Current Publications

Lawns provide a durable and functional surface for many outdoor activities while adding beauty to the landscape. For these reasons, a healthy, green lawn is the goal of many homeowners and landscape managers. Keeping a lawn healthy and green may require many management practices such as mowing, irrigation and aerification. Often, these practices will include fertilizing with supplemental nutrients at various times during the growing season. This promotes optimum turf color, improves re-growth, and increases tolerance to wear, drought, insects and disease. The broad number of fertilizer options available from retailers can make choosing a fertilizer difficult. However, choosing an …

Camper Outcomes Increase Regardless Of Session Length: Beyond Anecdotal Evidence Of Increased Competence, Independence And Friendship Skills, Mark F. Roark

Kinesiology and Health Science Faculty Publications

Session length may not be as vital to the accomplishment of developmental outcomes as directors are anecdotally sharing. Interestingly, no empirical support exists for the conventional wisdom that longer sessions have better outcomes than shorter sessions for campers. Dimock and Hendry (1929) found that campers’ level of development in general did not significantly vary whether they were at camp one or two months. They cautioned that this finding might not appropriately represent the actual effect of camp due to limitations in the measurement tool. Comparably, ACA’s Directions (2005) reported that session length was not a reliable predictor of camper developmental …
