The Ecological Interactions Of Sanak, Nancy Huntly, Spencer Wood, Roly Russell

Biology Faculty Publications

Ecology is not only about the interesting biology of organisms, as described for Sanak Island in the last chapter, but also about interactions: interactions between animals (including people), plants, microbes, the habitats that they live in, and the environments that surround them. The ecology of Sanak Island today reflects not only today's conditions, but also shows the imprint of the distant history of interactions of the island, especially, as we will see below, the imprint of the Aleut people that have made this island their home.

How Sanak Aleut Fit Into The Intertidal Food Web, Jennifer A. Dunne, Spencer Wood, Roly Russell, Nancy Huntly, Matthew Betts, Herbert Maschner

Biology Faculty Publications

Almost everyone learns about the concept of ecological "food chains" in grade school. An example of a marine food chain is shown on the left-hand side of the chart to the left: phytoplankton are eaten by mussels, which are eaten by octopus, which are eaten by sea otters, which are eaten by humans. These feeding interactions can be abstractly represented as five "nodes" connected in a single chain by four links, as shown on the right-hand side of the diagram to the left. The food chain shown is one of the thousands of interlinked food chains that make up the …

Beef Production And Consumption: Sustainable Alternatives, Jennifer W. Macadam, Roslynn Brain

Sustainable living involves choosing a lifestyle with minimal environmental impacts. The ultimate goal is to leave future generations with a healthier environment than the one we were born into. How can we do that with beef consumption? Beef is part of American culture, so is there a way to make wiser choices when it comes to purchasing beef ? The short answer is, yes!

Interactions Between Rocky Mountain Bighorn Sheep Ovis Canadensis Canadensis And Domestic Sheep Ovis Aries And The Biological, Social, Economic, And Legal Implications Of These Interactions On Usda Forest Service Lands In The Evanston/Mt. View Ranger District, Ashly Nicole Herrera

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

Strong evidence exists indicating domestic sheep (Ovis aries) can infect Rocky Mountain bighorn sheep (Ovis canadensis canadensis), a United States Forest Service (USFS) Region 4 sensitive species, with pneumonia (Callan 1991; Foreyt 1989, 1992, 1994; Foreyt and Lagerquist 1996; George et al 2008; Wehausen et al. 2011). Since the transmission of the pneumonic bacteria between the domestic and wild sheep is a result of bighorn sheep coming into contact with the bacteria carried in the mucous membranes of the domestic sheep, bighorn sheep at risk of initially contracting the bacteria are those individuals that enter areas currently being grazed or …

Effects Of Planting Date, Harvest Date, And Environmental Conditions On Germination Of Forage Kochia Accessions, Cody F. Creech

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forage kochia is used to re-seed areas in harsh environments that have been infested by annual weeds or disturbed by repetitive fires. It is an introduced perennial semi-shrub that is valuable to livestock and wildlife as a forage. The seed of forage kochia is very unpredictable and successful establishment in areas of low precipitation where it is utilized has often been erratic. Forage kochia seeding failures are costly and leave the land vulnerable to further degradation and erosion. This study was conducted to investigate how germination of forage kochia is affected by different harvest and planting dates, age of seed, …

Genetic Characterization Of Fine-Leaved Festuca Valesiaca Germplasm And Evaluation Of Their Relationship To The Festuca Ovina Complex, Yingmei Ma

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fine-leaved Festuca valesiaca has stress tolerance. However, its agronomic performance in the western United States and its genetic relationship to species of the Festuca ovina complex has not been investigated. Also, natural hybridization makes them difficult to identify. Given the species' potentials, our project was designed to identify Festuca valesiaca accessions that possess high biomass and seed yield and to examine their relatedness with the Festuca ovina complex.

The Festuca valesiaca accessions examined produced many small seeds. Seed production was correlated with the total biomass, plant height, and plant vigor. The Festuca valesiaca accessions examined were shorter than the control …

Emissions Calculated From Particulate Matter And Gaseous Ammonia Measurements From Commercial Dairy In California, Usa, Kori D. Moore, Christian C. Marchant, Emyrei Young, Randal S. Martin, Richard L. Pfeiffer, John H. Prueger, Jerry L. Hatfield

Space Dynamics Laboratory Publications

Emission rates and factors for particulate matter (PM) and gaseous ammonia (NH3) were estimated from measurements taken at a dairy in June 2008. Concentration measurements were made using both point and remote sensors. Filter-based PM samplers and optical particle counters (OPCs) characterized aerodynamic and optical properties, while a scanning elastic lidar measured particles around the facility. The lidar was calibrated to PM concentration using the point measurements. NH3 concentrations were measured using 23 passive samplers and 2 open-path Fourier transform infrared spectrometers (FTS). Emission rates and factors were estimated through both an inverse modeling technique using AERMOD coupled with measurements …

Aglite: A 3-Wavelength Lidar System For Quantitative Assessment Of Agricultural Air Quality And Whole Facility Emissions, Michael D. Wojcik, Kori D. Moore, Jerry L. Hatfield, Richard L. Pfeiffer, John H. Prueger, Randal S. Martin

Space Dynamics Laboratory Publications

Ground based remote sensing technologies such as scanning lidar systems (light detection and ranging) are increasingly being used to characterize ambient aerosols due to key advantages (i.e., wide area of regard (10 km2), fast response time (s-1), high spatial resolution (<10 >m) and high sensitivity). Scanning lidar allows for 3D imaging of atmospheric motion and aerosol variability, which can be used to quantitatively evaluate particulate matter (PM) concentrations and emissions. Space Dynamics Laboratory, in conjunction with USDA ARS, has developed and successfully deployed a lidar system called Aglite to characterize PM in diverse settings. Aglite is a portable scanning elastic …

Root Niche Partitioning Among Grasses, Saplings, And Trees Measured Using A Tracer Technique, Andrew Kulmatiski, Karen H. Beard

Wildland Resources Faculty Publications

Niche partitioning of resources by plants is believed to be a fundamental aspect of plant coexistence and biogeochemical cycles; however, measurements of the timing and location of resource use are often lacking because of the difficulties of belowground research. To measure niche partitioning of soil water by grasses, planted saplings, and trees in a mesic savanna (Kruger National Park, South Africa), we injected deuterium oxide into 102,000 points in 15, 154-m2 plots randomly assigned to one of five depths (0–120 cm) and one of three time periods during the 2008/2009 growing season. Grasses, saplings and trees all demonstrated an exponential …

Caehnorhabditis Elegans: A Low-Cost In Vivo Animal Model For Efficacy Studies Of Novel Antibiotics, Rylee Ann Gregory

Undergraduate Honors Capstone Projects

Since the 1940s, antibiotics have greatly reduced the adverse effects of infectious diseases caused by microbes. However, due to excessive, and often incorrect, use of known antibiotics, many organisms have adapted antibiotic resistance. Currently, over 70% of known infectious bacteria are resistant to at least one antibiotic. In the U.S. , 90,000 deaths occur each year due to infection by bacteria resistant to antibiotics. This number has increased by nearly 75,000 in the last 20 years. It is necessary, therefore, to continue developing new antibiotics in an effort to keep up with increasing antibiotic resistance. Traditional in vitro and whole …

Hazards At Low-Head Dams, Riley J. Olsen, Michael C. Johnson

International Junior Researcher and Engineer Workshop on Hydraulic Structures

ABSTRACT: Low-head dams are small structures that are built for many purposes, the most common being to impound small amounts of water for various uses. At certain flow conditions, a dangerous countercurrent, known as a roller, can form downstream of a low-head dam. This current possesses an upstream directed surface velocity that can effectively trap debris, as well as unsuspecting humans, at the downstream side of the dam. It is this current that is responsible for the deaths of many individuals that have ventured too close to these structures over the years. It is the objective of this study to …

Enhancing Alphabet Knowledge Instruction: Research Implications And Practical Strategies For Early Childhood Educators, Cindy D'On Jones, Sarah K. Clark, D. Ray Reutzel

Teacher Education and Leadership Faculty Publications

Alphabet knowledge is consistently recognized as the strongest, most durable predictor of later literacy achievement. Recent research offers practical implications for increased effectiveness of teaching alphabet knowledge to young children. In this article, we outline Enhanced Alphabet Knowledge instruction (EAK), a method of practical instruction that early childhood teachers can use to organize, plan, and teach the essential skills of alphabet knowledge. EAK emphasizes identifying the letter name and sound, recognizing the letter in text, and producing the letter form, through flexible, distributed cycles of review based on factors that influence acquisition of alphabet knowledge.

Cele Houre Memes: An Eccentric English Psalter-Hours In The Huntington Library, Alexa Sand

Art and Design Faculty Publications

The Ellesmere Psalter-Hours (EL 9 H17) consists of two distinct but related manuscripts, an earlier Psalter and a later partial Book of Hours written and illuminated in England between about 1310 and 1325. Alexa Sand shows what this unusual book reveals about lay devotion as an expression of class ambition and social networking among the gentry of northwestern England in this period of internecine strife and political turmoil. The manuscript’s material structure and its iconographic, textual, and heraldic contents reflect its emulation not only of similar prayer books created for laywomen belonging to the gentry class but also of specific …

Dermatopathy In Juvenile Angus Cattle Due To Vitamin A Deficiency, Thomas J. Baldwin, Kerry A. Rood, E. Jane Kelly, Jeffery O. Hall

Animal, Dairy, and Veterinary Science Faculty Publications

In juvenile cattle, vitamin A deficiency is reported most commonly as a neurological condition; only rarely are there dermatologic manifestations. In the current study, alopecia, severe epidermal and follicular orthokeratosis, and acanthosis due to hypovitaminosis A are reported in 2 of 32 Angus calves, with a third animal suspected. Affected animals responded to vitamin A supplementation, and no additional calves displayed signs. Vitamin A acts on skin by regulating DNA transcription in keratinocytes, reducing the number of tonofilaments and desmosomes, both involved in cell-to-cell adhesion. Hence, adequate levels of dietary vitamin A are necessary for normal keratinocyte turnover, and deficiencies …
