Nidus Idearum. Scilogs, Ii: De Rerum Consectatione, Florentin Smarandache
Branch Mathematics and Statistics Faculty and Staff Publications
Welcome into my scientific lab! My lab[oratory] is a virtual facility with noncontrolled conditions in which I mostly perform scientific meditation and chats: a nest of ideas (nidus idearum, in Latin). I called the jottings herein scilogs (truncations of the words scientific, and gr. Λόγος – appealing rather to its original meanings "ground", "opinion", "expectation"), combining the welly of both science and informal (via internet) talks (in English, French, and Romanian). In this second book of scilogs collected from my nest of ideas, one may find new and old questions and solutions, some of them already put at work, others …
Working Together To Combat Invasive Species Threats: Strategies For Facilitating Cooperation Between The National Park Service And States, Stephanie Showalter Otts, Catherine Janasie, Paula Cotter
Working Together To Combat Invasive Species Threats: Strategies For Facilitating Cooperation Between The National Park Service And States, Stephanie Showalter Otts, Catherine Janasie, Paula Cotter
Natural Resources Journal
Invasive species are a significant environmental and economic threat throughout the United States. Over 6,500 non-native species have been documented on national park lands. To adequately address invasive species issues, the National Park Service must work cooperatively with state governments to prevent the introduction and spread of non-native species. A variety of mechanisms, both formal and informal, are available to the National Park Service to cooperatively manage park ecosystems with their neighboring land management agencies. Coordination of programs can be achieved through simple informal working relationships between agency staff, incorporation of state laws into park policies, or negotiation of formal …

Inviting Everyone To The (Risk) Pool Party: Reforming The Premium Tax Credit To Boost Participation, Mary Leto Pareja
Inviting Everyone To The (Risk) Pool Party: Reforming The Premium Tax Credit To Boost Participation, Mary Leto Pareja
Faculty Scholarship
The year 2014 marked the first opportunity for American taxpayers to receive subsidized health insurance through the Affordable Care Act’s (“ACA”) new Premium Tax Credit (“PTC”). About 4.8 million people enrolled in an ACA plan in 2014 were eligible, and nearly 97% of these claimants were approved for advance payments of the PTC. The year 2015 marked the first tax return where taxpayers received the unpleasant surprise that they must repay excess credits due to reconciliation. Advance PTC estimates turned out to be highly inaccurate, with only 8% of claimants receiving accurate advance payments. A majority, 51%, had to repay …

A Park For Everyone: The National Park Service In Urban America, Sarah J. Morath
A Park For Everyone: The National Park Service In Urban America, Sarah J. Morath
Natural Resources Journal
This article examines the National Park Service’s past and future presence in urban America. Scholars, conservationists, and park administrators agree that urban park spaces and programming must be a focus of the National Park Service in its second century. This article explains the motivations behind the National Park Service’s first urban parks and describes the National Park Service’s recent emphasis on urban areas. From designations such as Pullman Park in Chicago, to initiatives like the Urban Agenda, the National Park Service is poised to engage urban America and create a new generation of park visitors.
Oil & Gas Drilling In National Parks, Elizabeth Ann Glass Geltman
Oil & Gas Drilling In National Parks, Elizabeth Ann Glass Geltman
Natural Resources Journal
While a great deal of public attention addresses the Halliburton loophole of the Energy Policy Act of 2005 and Bureau of Land Management efforts to regulate hydraulic fracturing on public lands, less attention has been paid to the National Park Service “9B Regulations,” which provide a national regulatory framework governing the exercise of oil and gas rights in national parks. This article begins with a review of law pertaining to oil and gas drilling in national parks. The article examines the tension in striking a balance between environmental protection, conservation of national lands, and achieving energy independence, including National Park …
The National Park Service Organic Act And Climate Change, Eric Biber, Elisabeth Long Esposito
The National Park Service Organic Act And Climate Change, Eric Biber, Elisabeth Long Esposito
Natural Resources Journal
This article examines the future of the National Park Service Organic Act in a changing climate. Managers and scholars have raised questions about whether the Organic Act gives the Park Service sufficient authority to undertake the steps necessary to adapt to climate change. This article concludes that the Organic Act and park-specific enabling acts, as interpreted by the courts, grant the Park Service wide discretion to pursue management options for adaptation to climate change impacts on national park resources. It also concludes that the Organic Act, properly understood, does impose some necessary constraints on agency decision-making, constraints that prevent inappropriate …
Student Preconceptions Of Arid, Urban Watershed Management And How Experiential Learning Might Contribute To Conceptual Change., Rachel Aliyah Thomas
Student Preconceptions Of Arid, Urban Watershed Management And How Experiential Learning Might Contribute To Conceptual Change., Rachel Aliyah Thomas
Water Resources Professional Project Reports
Voting-aged, freshman-level university students attending college in urban Southwest US cities are living in what is considered one of the most 'climate-challenged' regions of the entire country. Such students may not understand the issues and ways to manage an urban watershed. For instance, the Southwest faces climate change drought predictions and naturally occurring water scarcity. Urban populations continue to climb, pushing up demands on already scarce water resources. Urban watersheds present specific challenges, such as impermeable surfaces. Students need to understand these urban watershed management challenges and climate change stressors. I conducted a study in an introductory environmental science class …
Assessing The Geomorphological Effects Of Ungulate Exclosures On High Elevation Streams In The Valles Caldera National Preserve, New Mexico, Ryan Kelly
Water Resources Professional Project Reports
A catchment-scale approach to the connection between the terrestrial environment and aquatic ecosystems is important because of the context that it provides into stream form and function. A streams physical and chemical qualities are often delineated, in large part, by the surrounding catchment's terrestrial properties and features, such as geology, soils, vegetation and topography (Van Horn et al. 2012). For example, losses in catchment vegetation can result in a change in terrestrial organic carbon inputs into streams (Bunn et al. 1999). Four important dimensions of connection exist when describing the physical, chemical, and energetic interactions between the stream itself and …

Faculty and Staff Publications
The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside …

2015 Final Report: Status Of The Arizona Toad (Anaxyrus Microscaphus) In New Mexico, Mason J. Ryan, Ian M. Latella, Jacek Tomasz Giermakowski, Howard L. Snell
Biology Faculty & Staff Publications
In 2013, we initiated a field study to assess the status of the Arizona Toad (Anaxyrus microscaphus) in New Mexico. Herein we provide the results of three years (2013-2015) of range-wide population monitoring, a review of threat assessments, and several contributions to the basic ecology of the Arizona Toad in New Mexico. This work highlights the sensitivity of the species to abiotic factors and emphasizes the nature of annual population fluctuations in a variable environment. We provide analyses of environmental factors that influence toad reproductive behaviors, employ occupancy and detection modeling at breeding sites, and provide analyses of tadpole habitat …

Three-Dimensional Constraints On Human Cognition As Expressed In Human Language, Christopher Adam
Three-Dimensional Constraints On Human Cognition As Expressed In Human Language, Christopher Adam
Linguistics ETDs
Those advocating the existence of a distinct language instinct generally claim that human language is not reliant on general human cognition. However, limitations on recursive patterns in human language are universally attested, from the micro-level elements of phonology, throughout the mid-level elements of morphology and syntax, and up to the macro-level elements of reference in discourse. What these limitations appear to reveal is a pattern seen in other areas of human cognition, namely the human inability to actively recall and balance more than three interdependent variables at a time. Building upon these data patterns and an array of typological postulates, …
Mens Life History, Testosterone, And Health, Louis Calistro Alvarado
Mens Life History, Testosterone, And Health, Louis Calistro Alvarado
Anthropology ETDs
Testosterone is hypothesized to mediate life history trade-offs between reproduction and survival in men, promoting mating effort over other forms of investment, which entails energetic and mortality costs. Sexually dimorphic musculature represents one form of somatic investment in mating. Favorable energy availability is posited to promote preferential investment in mating effort through upregulated testosterone production and augmented musculature, whereas nutritional constraint is predicted to downregulate testosterone to facilitate a diminished, thriftier phenotype. Furthermore, life history trajectories influencing mens testosterone levels have important health implications for androgen-sensitive disease. Here, I examine broad features of men's life history and health, and their …
The Effects Of Ketorolac And Its Enantiomers On Breast Cancer Proliferation And Metastasis, Amanda Sheree Peretti
The Effects Of Ketorolac And Its Enantiomers On Breast Cancer Proliferation And Metastasis, Amanda Sheree Peretti
Biomedical Sciences ETDs
Breast cancer is the second leading cause of cancer related deaths in women. Advanced breast cancer can metastasize to the lungs, liver, bones and brain becoming fatal conditions for many patients. There is a dire need for metastasis preventing medications, however the process required for a medication to become FDA approved for clinical use is long and arduous. Studies have found promising benefits for breast cancer patients given ToradolTM, or racemic ketorolac, as an NSAID during resection surgery. However, long-term use of racemic ketorolac is not recommended. Currently FDA-approved for use in the racemic form, ketorolac has the potential to …
Paratransgenic Control Of Pierce's Disease, Arinder K. Arora
Paratransgenic Control Of Pierce's Disease, Arinder K. Arora
Biology ETDs
Pierce's Disease (PD) is a deadly grapevine disease, which is caused by a Gram negative bacterium, Xylella fastidiosa and transmitted by leafhoppers commonly known as sharpshooters, including the glassy-winged sharpshooter (GWSS, Homalodisca vitripennis). We developed paratransgenic control of PD using a commensal bacterium Pantoea agglomerans E325. The GWSSs acquired enhanced green fluorescent (EGFP)-expressing P. agglomerans from an artificial feeding system and the bacteria persisted within the insect foregut for two weeks. P. agglomerans was selected as the paratransgenic control agent based on its persistence within the sharpshooter foregut, a niche also inhabited by X. fastidiosa. P. agglomerans lines secreting two …
Transcriptional Regulation Of Muscle Development In Drosophila Melanogaster, Tonya M. Brunetti
Transcriptional Regulation Of Muscle Development In Drosophila Melanogaster, Tonya M. Brunetti
Biology ETDs
The transcriptional regulation of muscle development involves several complex processes that must work together in order to form functional, syncytial muscle cells. However, when transcription is mis-regulated, muscle development is often times negatively affected and can lead to muscle diseases such as muscular dystrophy and cardiac myopathies. In order to gain more insight into how transcription is regulated, I use Drosophila melanogaster as a model for understanding muscle development. In chapter one, I use a traditional genetic screen to phenotypically and molecularly identify two Hox co-factors, extradenticle and homothorax, that have the ability to change muscle identity. Additionally, in chapter …
Flight Muscle Progenitor Populations In Drosophila Melanogaster, Elizabeth Carvosso Clarke
Flight Muscle Progenitor Populations In Drosophila Melanogaster, Elizabeth Carvosso Clarke
Biology ETDs
We use the Drosophila system to define how genes control muscle development and function. Many of the genes in the fruit fly, Drosophila melanogaster, are conserved with higher animals, and so our results can be important in understanding mechanisms of vertebrate muscle development and disease. Study of the flight muscle progenitor populations in Drosophila gives clearer understanding of the genetic regulatory networks that lead to the development of flight muscle. The direct flight muscles (DFMs) and indirect flight muscles (IFMs) arise from the myoblast population of the notal region of the Drosophila wing imaginal disc. Within the myoblast population, there …
A Life History Of The Roundnose Minnow, Dionda Episcopa, In The Middle Pecos River Valley, New Mexico, Michael A. Farrington
A Life History Of The Roundnose Minnow, Dionda Episcopa, In The Middle Pecos River Valley, New Mexico, Michael A. Farrington
Biology ETDs
Life history aspects of Roundnose Minnows, Dionda episcopa, were examined for specimens collected between 2011 and 2013 in El Rito Creek, near Santa Rosa New Mexico. A recent study examining DNA suggested that, instead of supporting a widespread population of the Roundnose Minnow, New Mexico is actually home to two evolutionarily distinct Roundnose Minnow populations. This focus of this study is on the life history attributes of what may become a newly described species of Dionda. Modal class progression analysis (Bhattacharya method) documented four distinct age classes of Roundnose Minnows within El Rito Creek. Sex ratios deviated from the expected …
Gene Duplications During Experimental Evolution Of Caenorhabditis Elegans: Duplication Rates And Evolutionary Responses, James Charles Farslow
Gene Duplications During Experimental Evolution Of Caenorhabditis Elegans: Duplication Rates And Evolutionary Responses, James Charles Farslow
Biology ETDs
Copy-number variants (CNVs) are a ubiquitous form of genetic variation. How often this form of variation arises and its adaptive significance are active areas of contemporary research. This work presents evidence regarding both of these subjects. First, it demonstrates that gene duplications occur at a frequency two orders of magnitude greater than point mutations. Specifically, the gene duplication rate is estimated to be 1.2 x 10-7/gene/generation, compared to a point mutation rate on the order of ~10-9/site/ generation. Second, it was found that populations in a low state of fitness due to mutation accumulation could recover some or all of …
The Impact Of Temperature, Ph And Environmental Heterogeneity On Prokaryotic Diversity In Yellowstone National Park Thermal Springs, Xiaoben Jiang
The Impact Of Temperature, Ph And Environmental Heterogeneity On Prokaryotic Diversity In Yellowstone National Park Thermal Springs, Xiaoben Jiang
Biology ETDs
Yellowstone National Park (YNP) is one of the largest and most diverse hydrothermal areas on Earth. Extensive culture-independent studies in YNP thermal springs have shown dramatic taxonomic and metabolic diversity in microbial communities. We conducted a survey of bacterial communities along temperature gradients in three alkaline springs with similar geochemistries at the local scale. With these data, we investigated the influence of environmental variables on bacterial community diversity and assemblages along a broad temperature range using high throughput 454 pyrosequencing. Previous studies have suggested that pH is the driver of microbial diversity in thermal springs among geographical regions or at …
Quantifying Temperature Sensitivity Of Soil Respiration Across A Range Of Semi-Arid Biomes, Michelle Nuanez
Quantifying Temperature Sensitivity Of Soil Respiration Across A Range Of Semi-Arid Biomes, Michelle Nuanez
Biology ETDs
Soils in semi-arid regions store approximately 10% of earths soil organic carbon, the substrate which microbes oxidize, resulting in the largest source of carbon to the atmosphere from terrestrial ecosystems. Semi-arid regions are expected to experience increased temperatures and altered precipitation regimes over the next 100 years, altering soil temperature and water, the two predominant drivers in soil respiration processes. In this study we quantify the temperature sensitivity of soil respiration in five semi-arid biomes ranging from desert grassland to ponderosa pine forest along an elevational/climate gradient in central New Mexico. We measured statistically similar temperature sensitivities in 4 of …
Effects Of Stream Edges On Algal Biomass In The Middle Rio Grande, Steven Daniel Scholle
Effects Of Stream Edges On Algal Biomass In The Middle Rio Grande, Steven Daniel Scholle
Biology ETDs
In river systems, there are many factors that impede or facilitate algal standing stock and therefore impact primary production in these environments. I am particularly interested in the influence of edges in riverine systems and how these geomorphic features affect the available surface area for algal production. This study investigates the middle Rio Grande system near Albuquerque, New Mexico, USA. The middle Rio Grande is a turbid, partially braided lotic ecosystem. Although edge characteristics can vary widely, especially between errosional and depositional banks, I hypothesize that edges become important zones of primary production, due in part to decreased water depth, …
Disturbance Events In Arid Ecosystems: Comparisons Of Enzyme Activity Profiles Across Multiple Soil Microbial Communities, Daniel Douglas Warnock
Disturbance Events In Arid Ecosystems: Comparisons Of Enzyme Activity Profiles Across Multiple Soil Microbial Communities, Daniel Douglas Warnock
Biology ETDs
Arid ecosystems are home to approximately 35% of earth's human population, and approximately 40% of earth's terrestrial carbon. These systems are especially prone to releasing the stored carbon when under global climate change (GCC) related pressures. My goal for these studies was to expand on our already growing knowledge base of how the soil microbial communities in disturbed arid ecosystems undergo shifts in functional patterns, as they respond to a rapidly changing environment. In chapter two, I examined the overall functional activity levels and functional behaviors exhibited by both pinon and juniper supported RAM communities in the context of widespread, …
Citizen Science Ecological Monitoring: For Whom?, Cameron Weber
Citizen Science Ecological Monitoring: For Whom?, Cameron Weber
Architecture and Planning ETDs
In ecosystems undergoing rapid change, habitat management and restoration present special challenges for land managers. To reduce uncertainty about such systems and, thereby, improve the success of their decisions, managers may consult ecological monitoring data. Limitations in time and resources for data collection have highlighted the role that citizen science can play in applied conservation science. One citizen science project, the Bosque Ecosystem Monitoring Program (or BEMP), supplies decision makers with ecological monitoring information about the historically dynamic Middle Rio Grande riparian forest corridor (or bosque) ecosystem through engaging nearby K-12 students in collecting ecological data over a large area. …
Evolving Efficient Foraging Behavior In Biologically-Inspired Robot Swarms, Joshua Peter Hecker
Evolving Efficient Foraging Behavior In Biologically-Inspired Robot Swarms, Joshua Peter Hecker
Computer Science ETDs
Human beings are driven to explore distant new worlds as we seek to better understand our place in the Universe. Because of the inherent dangers of human spaceflight, we often send robots as surrogate explorers, controlled from millions of miles away by teams of capable rover drivers here on Earth. As technology continues to advance, scientists and engineers aspire to build low-cost, durable, fully autonomous rovers to succeed today's tele-operated extraplanetary explorers. Here we aim to advance this goal by designing and programming robots that can successfully navigate unknown and variable environments. We present a swarm robotics system that mimics …
