Oregon Aspen Project, Forest Restoration Partnership Dec 2010

Oregon Aspen Project, Forest Restoration Partnership

Aspen Bibliography

The Oregon Aspen Project was initiated in response to the decline of aspen groves in Oregon and throughout the Western United States, and the lack of information to guide managers interested in stewardship to enhance this resource. There were three central goals and accompanying objectives for this project which are listed below. The project accomplishments are provided below each bulleted objective

Estimating Expected Fire Suppression Cost Savings Due To Vegetation Management On Pinyon Pine And Juniper Invaded Sagebrush Rangelands, Kimberly Rollins, Mimako (Mimi) Kobayashi Dec 2010

Estimating Expected Fire Suppression Cost Savings Due To Vegetation Management On Pinyon Pine And Juniper Invaded Sagebrush Rangelands, Kimberly Rollins, Mimako (Mimi) Kobayashi

Reports

Wildfire suppression costs in the United States have increased steadily over the last decades (Stephens and Ruth 2005, Calkin et al. 2005, Gebert et al 2007, Westerling et al. 2006, GAO 2007), with related expenditures by the U.S. Forest Service and Bureau of Land Management exceeding a billion dollars per year in four out of the seven years leading up to 2006 (Gebert et al 2008). Pre-­fire vegetation management on public lands is recognized as an important tool for reducing expected wildfire suppression costs (GAO 2007).Using data from wildfire suppression costs across the US, Lankoande and Yoder (2006) estimate that …

Effects Of Three Emulsion Compositions On Taste Thresholds And Intensity Ratings Of Five Taste Compounds, J. E. Thurgood, Silvana Martini Dec 2010

Effects Of Three Emulsion Compositions On Taste Thresholds And Intensity Ratings Of Five Taste Compounds, J. E. Thurgood, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study assessed the effects of three emulsified systems on taste thresholds and the near-threshold taste intensities of the five tastes (sweet, sour, salty, bitter and umami). Emulsions were formulated with different lipid chemical compositions. Lipid addition in an emulsified form significantly increased thresholds for sour and bitter tastes produced by citric acid and quinine hydrochloride, respectively. No significant differences were found in the threshold levels in emulsions formulated with different lipids for the five tastes evaluated. In general, for the same tastant concentration, taste intensities for sour and bitter tastes were lower in emulsions compared with the aqueous solutions, …

Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson Dec 2010

Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For centuries, scientists have been intrigued by the high amount of biodiversity that is found in the deserts of North America. Recently, several studies have investigated the causes of the high diversity found in desert-dwelling mammals, reptiles, and amphibians. These studies have found that many of these organisms seem to have diversified in response to the same historical events. Little work has been done, however, on diverse desert-dwelling insect groups. In this dissertation, I investigate the patterns of genetic diversity in four groups of nocturnal wasps called velvet ants. I compare the patterns of genetic diversity to the historical events …

Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams Dec 2010

Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two independent studies were conducted to assess the effects of feeding condensed tannin (CT)-containing forages to continuous cultures to evaluate their impacts on ruminal fermentation and digestibility, with an emphasis on methane (CH4) and ammonia-N (NH3-N) production. In Chapter 3, treatments consisted of: 1) 100% alfalfa hay (AH), 2) 50% AH and 50% birdsfoot trefoil hay (dry matter (DM) basis; AHBFTH), and 3) 100% birdsfoot trefoil hay (BFTH). Three replicated runs lasted 8 d each, with the first 5 d allowed for microbial adaptation to the diets, and 3 d for data collection and sampling. Methane, neutral detergent fiber (NDF) …

Establishment And Aesthetic Value Of Native Grass, Legume, And Forb Species For Grassland Restoration In The Northern Intermountain West, Bridget M. Atkin Dec 2010

Establishment And Aesthetic Value Of Native Grass, Legume, And Forb Species For Grassland Restoration In The Northern Intermountain West, Bridget M. Atkin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Interest in the restoration of landscapes native to the Intermountain West is growing as the value of these arid ecosystems is increasingly recognized. Many landscapes within the Intermountain region have been impacted by grazing, development, recreation, and other human-caused disturbances. The complex relationships within the native plant communities of these arid landscapes need to be well-understood biologically, while considering their aesthetic contribution, if restoration efforts are to succeed. Although the use of ecologically appropriate native species is increasing in popularity, there is discontinuity between aesthetics and meaningful ecological contributions. A series of studies was designed to aid in the restoration …

Maporal Hantavirus Β-Integrin Utilization And Sensitivity To Favipiravir, Kristin K. Buys Dec 2010

Maporal Hantavirus Β-Integrin Utilization And Sensitivity To Favipiravir, Kristin K. Buys

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hantaviruses are members of the Bunyaviridae family of viruses. Pathogenic hantaviruses are the etiologic agents of hemorrhagic fever with renal syndrome (HFRS), a disease principally endemic in the Old World, and hantavirus pulmonary syndrome (HPS), a disease primarily restricted to the Americas. Maporal virus (MPRLV), a recently isolated hantavirus, has been found to cause disease in hamsters that resembles HPS in humans. However, the virus has not been linked to human cases of HPS. Considerable evidence suggests that β-integrin usage mediating infection may serve to distinguish hantaviruses pathogenic to humans from nonpathogenic, but this receptor usage pattern information is not …

Effect Of Mica Content On Surface Infiltration Of Soils In Northwestern Kern County, California, Steven Keyes Stakland Dec 2010

Effect Of Mica Content On Surface Infiltration Of Soils In Northwestern Kern County, California, Steven Keyes Stakland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A soils infiltration rate (IR) is the measured rate that soil is able to absorb water, either from precipitation or irrigation. A low IR can cause damage to crops if the necessary amount of water cannot penetrate to the plant roots in the time needed. The damage can be common in permanent plantings such as almond and pistachio orchards where regular tillage is avoided. This indicates a physical aspect to the problem because tillage increases IR. However, there is also an electrochemical side to infiltration problems because certain calcium surfactant treatments can increase IR. Various other methods have been used …

The Usu Tree Inventory Website: A Case Study Of An Interactive Online Woody Plant Education Resource, Benjamin W. Harris Dec 2010

The Usu Tree Inventory Website: A Case Study Of An Interactive Online Woody Plant Education Resource, Benjamin W. Harris

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The USU tree inventory website is an interactive, online tree education resource that I developed to allow students and community members to locate, identify and learn about trees on the USU campus. Students in two USU courses that teach woody plant material used the website during one semester and were surveyed about their experience. Less than half of the students accessed the website, but those that did found it useful as a supplement to traditional instruction. Most students were likely to recommend the website to another person and to use the website in the future.
