Site-Based And Nonsite Archaeological Survey: A Comparison Of Two Survey Methods In The City Of Rocks, Idaho, Patrick Reed Mcdonald May 2015

Site-Based And Nonsite Archaeological Survey: A Comparison Of Two Survey Methods In The City Of Rocks, Idaho, Patrick Reed Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Archaeology in the western United States frequently employs pedestrian survey of the ground surface to locate and identify archaeological sites. Proponents of alternative survey techniques suggest that site-based survey may be inherently flawed and will not accurately detect, document, or account for artifacts located outside of site boundaries. Site-based survey identifies artifacts, and then searches the area more intensively in an attempt to identify a spatial break in artifact presence. Nonsite approaches utilize point plotting of all discovered artifacts in order to quantitatively identify relationships between artifacts. Quantitative analysis removes a level of researcher bias from the interpretation of past …

Investigations Of Cho 1-15 And Silk Gland Cell Line Development, Susan Kathleen Robinson May 2014

Investigations Of Cho 1-15 And Silk Gland Cell Line Development, Susan Kathleen Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The BioProcessing Demonstration and Training Laboratory was established with a collaboration between Utah State University and Thermo Fisher-Scientific, Inc. This lab was developed into a fully functioning tissue culture facility. Demonstration of tissue culture procedures were necessary for the lab to be industry-fully qualified. The CHO 1-15 cell line protocols were optimized by establishing conditions for reproducibility in shaker flasks and bioreactors (2 to 250 L capacity). CHO 1-15 is the cell line of choice for protein production in the bio-manufacturing industry. Oxidative stress is a problem in the industry because it can cause a decrease in protein production. Mesobiliverdin …

Reproductive Biology And Impacts Of Energy Development On Physaria Congesta And Physaria Obcordata (Brassicaceae), Two Rare And Threatened Plants In The Piceance Basin, Colorado, Sarah Lynn Clark May 2013

Reproductive Biology And Impacts Of Energy Development On Physaria Congesta And Physaria Obcordata (Brassicaceae), Two Rare And Threatened Plants In The Piceance Basin, Colorado, Sarah Lynn Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Oil and gas development has increased profoundly over the last 20 years in the United States. A large underground deposit of natural gas has been found in the Piceance Basin, which is located in the northwestern part of the state of Colorado. This deposit occurs in an area inhabited by two rare mustard species commonly named the Dudley Bluffs bladderpod and the Dudley Bluffs twinpod. These two plant species are also listed as threatened by the US Fish and Wildlife Service. Concerns about gas development effects on these rare plants have motivated research that quantifies these potential impacts. Through funding …

Pseudo-Diel Vertical Migration In Zooplankton: A Whole-Lake 15N Tracer Experiment, Xavier Armengol, Wayne A. Wurtsbaugh, Antonio Camacho, Maria R. Miracle Jan 2012

Pseudo-Diel Vertical Migration In Zooplankton: A Whole-Lake 15N Tracer Experiment, Xavier Armengol, Wayne A. Wurtsbaugh, Antonio Camacho, Maria R. Miracle

Watershed Sciences Faculty Publications

Diel vertical migration (DVM) of zooplankton is commonly considered an adaptation for feeding in food-rich and warm surface waters at night and avoiding visual predators during the day. However, the critical assessment of migration patterns frequently suggests that: (i) zooplankton may leave deeper waters with rich, deep-chlorophyll layers and move into the epilimnion where food resources are lower and/or (ii) the night-time increase in epilimnetic plankton abundance is not matched by a density decrease in deeper strata. To study these discrepancies, we measured DVM of zooplankton in a 1.3-ha Spanish karst lake (Laguna del Tejo) where the phytoplankton in the …

The Selaginella Genome Identifies Changes In Gene Content Associated With The Evolution Of Vascular Plants, J. A. Banks, T. Nishiyama, M. Hasebe, J. L. Bowman, M. Gribskov, C. Depamphilis, Paul G. Wolf Jan 2011

The Selaginella Genome Identifies Changes In Gene Content Associated With The Evolution Of Vascular Plants, J. A. Banks, T. Nishiyama, M. Hasebe, J. L. Bowman, M. Gribskov, C. Depamphilis, Paul G. Wolf

Biology Faculty Publications

Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in …

Relationship Of Climate And Growth Of Quaking Aspen (Populus Tremuloides) In Yellowstone National Park, Erik S. Jules, Allyson L. Carroll, Matthew J. Kauffman Jan 2010

Relationship Of Climate And Growth Of Quaking Aspen (Populus Tremuloides) In Yellowstone National Park, Erik S. Jules, Allyson L. Carroll, Matthew J. Kauffman

Aspen Bibliography

Quaking aspen is a widespread tree that is in decline across wide areas of western North America, and is predicted to experience a large range shift if future climate predictions are realized. The purpose of our study was to determine what climate factors have influenced aspen growth in Yellowstone National Park, USA, and to determine whether these climatic influences vary across a heterogeneous landscape. We extracted increment cores from 10-12 aspen in each of 16 stands spread across a 1,526 km2 area. Using ring widths, we created a182-year standardized chronology from 1821 to 2003 A.D. composed of 151 series. We …

Investigations Into Earthworm Control On Airports, T. Seamans, G. Bernhardt, D. Steyer May 2009

Investigations Into Earthworm Control On Airports, T. Seamans, G. Bernhardt, D. Steyer

Wildlife Damage Management Conference

Earthworms, though generally considered beneficial for soil conditioning, can become a hazard at airports. When found in large numbers on runways or taxiways after heavy rainfall, they create slippery conditions for aircraft rolling over them. Additionally, earthworms attract birds, especially gulls, thereby increasing the risk of bird strikes to aircraft that are landing or taking off. For example, during a 35-minute period on 3 September 2004 at Calgary International Airport (YYC), a B737 of Westjet and an A319 of Air Canada aborted takeoffs after multiple strikes with gulls attracted to the runways to feed on earthworms. The B737 had strikes …

Retrospective Barrier Placements For A Skunk Rabies Epizootic In Nw Wyoming, C. Ramey, K. Mills, R. Mclean, R. Engeman, J. Fischer May 2009

Retrospective Barrier Placements For A Skunk Rabies Epizootic In Nw Wyoming, C. Ramey, K. Mills, R. Mclean, R. Engeman, J. Fischer

Wildlife Damage Management Conference

Striped skunks (Mephitis mephitis) are the most important reservoir of rabies on the Great Plains. In August, 1988 a skunk rabies epizootic proceeded from the "index case" west of Cowley, WY. By 1991, epizootic had reached nearly all areas in the Shoshone River Basin (SRB), and it ended in 1993. This area and the remainder of the SRB had been previously considered rabies-free. The USDA's Wildlife Services (WS) cooperated with state and local officials in a rabies monitoring and control program starting in 1990. Using information from the literature, signs, tracks, and radio-telemetry of normal and rabid skunks, …

The Regulation Of Epithelial Sodium Channels In Mammalian Taste Receptor Cells, Arian F. Baquero Gonzalez May 2009

The Regulation Of Epithelial Sodium Channels In Mammalian Taste Receptor Cells, Arian F. Baquero Gonzalez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nutrient recognition is one of the main physiological roles of the gustatory system. In mammals, it is well established that the taste of sodium salts is primarily mediated by sodium influx through the epithelial sodium channel. The epithelial sodium channel is a sodium-specific ion channel that is expressed across a wide range of transporting epithelia such as colon, kidney, and taste. In addition to its role as a salt taste receptor, sodium influx through the epithelial sodium channel is important systemically for maintaining sodium balance and blood pressure. Following our earlier work on the endocrine regulation of salt taste at …

Application Of Electrified Fladry To Decrease Risk Of Livestock Depredation By Wolves (Canis Lupus), Nathan J. Lance May 2009

Application Of Electrified Fladry To Decrease Risk Of Livestock Depredation By Wolves (Canis Lupus), Nathan J. Lance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wolf (Canis lupus) predation on livestock can cause economic and emotional hardships for livestock producers, complicating the balance of wolf conservation with other human interests. New management tools that decrease risk of predation may offer additional flexibility or efficiency for both livestock producers and management agencies. I examined 1) the efficacy of electrified fladry compared to fladry at protecting a food source from wolves in captivity, 2) the efficacy of electrified fladry for reducing wolf use of pastures and preventing depredations, and 3) the applicability of electrified-fladry. In captivity I tested the reaction from 15 groups (46 wolves) …

Sonication Assisted Synthesis Of Oligomannosides, Christabel Tomla Tanifum May 2009

Sonication Assisted Synthesis Of Oligomannosides, Christabel Tomla Tanifum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Oligomannosides prevalently exist as cell surface antigens. They play important roles in diseases such as viral infection and cancer, and they have been shown to be useful as candidates for vaccines. HIV, one of the most devastating modern diseases, has a high content of mannose sugars on its envelope glycoprotein gp120. Oligomannosides of the HIV virus, also called Man9, which are found on the glycoprotein gp120, have been shown to play a protective role for the HIV virus, shielding highly conserved protein domains of gp120 from proteolytic attacks. Thus gp120 plays an important role in HIV infection of cells, being …

Microbial Diversity And Microbial Abundance In Salt-Saturated Brines: Why Are The Waters Of Hypersaline Lakes Red?, Aharon Oren Jan 2009

Microbial Diversity And Microbial Abundance In Salt-Saturated Brines: Why Are The Waters Of Hypersaline Lakes Red?, Aharon Oren

Natural Resources and Environmental Issues

Salt-saturated lakes such as the North Arm of Great Salt Lake and saltern crystallizer ponds contain 10-10 and more red microorganisms ml-1. Even the Dead Sea occasionally turns red due to microbial blooms. Three types of organisms may contribute to the coloration: the alga Dunaliella salina rich in carotene, halophilic Archaea (family Halobacteriaceae) containing 50-carbon bacterioruberin carotenoids and sometimes also retinal proteins (bacteriorhodopsin, halorhodopsin), and the recently discovered Salinibacter (Bacteroidetes) which contains pigment salinixanthin (an unusual acylated C40-carotenoid glucoside) as well as different retinal pigments. Bacteriorhodopsin and halorhodopsin enable the cells to directly use light energy for respectively the outward …

Systematics Of The Sympetrine Dragonflies With Emphasis On The Phylogeny, Taxonomy, And Historical Biogeography Of The Genus Sympetrum (Odonata: Libellulidae), Erik M. Pilgrim May 2006

Systematics Of The Sympetrine Dragonflies With Emphasis On The Phylogeny, Taxonomy, And Historical Biogeography Of The Genus Sympetrum (Odonata: Libellulidae), Erik M. Pilgrim

Biology

Within dragonflies and damselflies, the family Libellulidae is the largest. The systematics have never been analyzed in a phylogenetic context. Using both molecular and morphological characters, this dissertation is the first study to address the phylogenetics of the Libellulidae, the phylogenetics and historical biogeography of Sympetrum, and several species-level disputes within Sympetrum. Phylogenetic study of the family Libellulidae revealed that many of the libellulid subfamilies (Brachydiplactinae, Leucorrhininae, Sympetrinae, Trameinae, Trithemistinae, and Urothemistinae) were paraphyletic. Wing venation characters were not useful for delineating the hierarchy of taxa within Libellulidae. Study of the systematics of Sympetrum shows that S. navasi …

Revegetation Of Reconstructed Reaches Of The Provo River, Heber Valley, Utah, John A. Rice Jan 2006

Revegetation Of Reconstructed Reaches Of The Provo River, Heber Valley, Utah, John A. Rice

All U.S. Government Documents (Utah Regional Depository)

Prior to the 1950s, the middle Provo River in Utah offered outstanding fish and wildlife habitat. This was due in part to the Provo River freely meandering through the Heber Valley. These bends in the river provided deep holes for fish and a dense streamside forest for many species of birds. This productive habitat was altered in the 1940s and 1950s when the river was dammed, channelized, and forced between dikes (figure 1). These dikes were constructed by the USDI Bureau of Reclamation (USBR) to contain high flows that came from additional water added to the Provo River from transbasin …

Development Of Nicarbazin As A Reproductive Inhibitor For Resident Canada Geese, Kimberly S. Bynum, Christi A. Yonder, John D. Eisemann, John J. Johnston, Lowell A. Miller

Wildlife Damage Management Conference

Expanding populations of resident Canada geese that remain in suburban and urban areas year-round often result in increased conflicts with humans. Non-lethal and humane means are needed for managing the size of Canada goose flocks residing near or on airports, golf courses, industrial parks, government sites, and city parks. A side effect of nicarbazin, a veterinary drug used to control coccidiosis in chickens, is decreased egg production and hatching. Exploiting this side effect, studies of nicarbazin for reducing the hatchability of eggs from Canada geese were conducted. An initial study in Cotumix quail verified reduction in hatchability in a species …

Battle At The Bridge: Using Participatory Approaches To Develop Community Researchers In Ecological Management, Jonathan Long, Delbin Endfield, Candy Lupe, Mae Burnette

Natural Resources and Environmental Issues

Land-based communities need problem solvers who can address ecological degradation by bridging gaps between community and outside knowledge systems. Through our experience working for the Watershed Program of the White Mountain Apache Tribe, we have wrestled with the challenge of making ecological research more useful to tribal communities, particularly those that have become highly skeptical of conventional research. Simply importing or exporting knowledge does little to solve long-term ecological problems, which instead require an active dialogue between community and outside knowledge systems to help local institutions evolve with environmental changes. To fulfill these roles, individual need skills in listening, speaking …

Binge Eating Disorder And Its Relationship To Bulimia Nervosa And Obesity, Lara Schultz Lacaille May 2002

Binge Eating Disorder And Its Relationship To Bulimia Nervosa And Obesity, Lara Schultz Lacaille

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent research indicates that 2% to 4% of the population meet diagnostic criteria for the newly proposed binge eating disorder, and that it is much more common (30%) among the treatment-seeking obese. Although recognized as a significant problem, binge eating disorder is l1l not well understood, and there is debate about whether binge eating disorder is a distinct disorder. It has been argued that binge eating disorder is simply a variant or milder form of bulimia nervosa and not a separate and distinct disorder. Researchers have begun to study this population in greater depth in order to assess the characteristics …

Physiological Importance Of 1,25(Oh)2D3 Membrane-Initiated And Nuclear Actions In Chickens As A Function Of Growth, And Maturation In Male And Female Chickens, Birgitta Larsson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is well established that l,25(OH)2D3 is a major regulator of calcium homeostasis. The steroid exerts its effects on its target organs by two mechanisms, a slow mechanism mediated by nuclear vitamin D receptors (nVDR), and a rapid mechanism mediated by the l,25(OH)2D3 membrane-associated rapid response steroid binding protein (l,25D3-MARRS bp). In this dissertation, the physiological relevance of membrane initiated steroid signaling was investigated by studying the correlation of age in male and female chickens with the magnitude of responses to l,25(OH)2D3 in duodena from 7-, 14-, 28-, and …

The Educational Pipelinie For Women In Biology: No Longer Leaking?, Louise Luckenbill-Edds

ADVANCE Library Collection

Describing the past 30 years of progress toward gender equity in science, one observer wrote: "Although optimistic about future prospects, I must also point out some daunting toads and serpents lurking in the gardens of science. These challenge the rising generation of young scientists to be no less intrepid [that past activists who catalyzed change]" (Herschbach 1999, p. 66). The failure of the sciences to attract and retain women has meant a loss of diversity, as well as a loss of talent and creativity, that impoverishes research viewpoints and limits effective communication of science with diverse sectors of society.
