Forest dynamics plots, which now span longitudes, latitudes, and habitat types across the globe, offer unparalleled insights into the ecological and evolutionary processes that determine how species are assembled into communities. Understanding phylogenetic relationships among species in a community has become an important component of assessing assembly processes. However, the application of evolutionary information to questions in community ecology has been limited in large part by the lack of accurate estimates of phylogenetic relationships among individual species found within communities, and is particularly limiting in comparisons between communities. Therefore, streamlining and maximizing the information content of these community phylogenies is …

Shigella spp. are causative agents of bacillary dysentery, a human illness with high global morbidity levels, particularly among elderly and infant populations. Shigella infects via the fecal-oral route, and its virulence is dependent upon a type III secretion system (T3SS). Two components of the exposed needle tip complex of the Shigella T3SS, invasion plasmid antigen D (IpaD) and IpaB, have been identified as broadly protective antigens in the mouse lethal pneumonia model. A recombinant fusion protein (DB fusion) was created by joining the coding sequences of IpaD and IpaB. The DB fusion is coexpressed with IpaB's cognate chaperone, IpgC, for …

Fe Protein-Independent Substrate Reduction By Nitrogenase Mofe Protein Variants, Karamatullah Danyal, Andrew J. Rasmussen, Stephen M. Keable, Boyd S. Inglet, Studipta Shaw, Oleg A. Zadvornyy, Simon Duval, Dennis R. Dean, Simone Raugei, John W. Peters, Lance C. Seefeldt

Chemistry and Biochemistry Faculty Publications

The reduction of substrates catalyzed by nitrogenase normally requires nucleotide-dependent Fe protein delivery of electrons to the MoFe protein, which contains the active site FeMo cofactor. Here, it is reported that independent substitution of three amino acids (β- 98Tyr→His, α-64Tyr→His, and β-99Phe→His) located between the P cluster and FeMo cofactor within the MoFe protein endows it with the ability to reduce protons to H2, azide to ammonia, and hydrazine to ammonia without the need for Fe protein or ATP. Instead, electrons can be provided by the low-potential reductant polyaminocarboxylate-ligated Eu(II) (Em values of −1.1 to −0.84 V vs the normal …

Successes And Struggles Of Teaching: Perspectives Of Beginning, Mid-Career, And Veteran Teachers, Alyson Leah Lavigne, Amanda Rabidue Bozack

Teacher Education and Leadership Faculty Publications

Wages that are not commensurate with level of education (National Association of Colleges and Employers [NACE], 2013), demanding responsibilities, and pressures leveraged by high-stakes testing and evaluation, have led to soaring rates of attrition and a disproportionate number of beginning teachers in U.S. classrooms. Teacher experience has decreased from a mode of 15 years in 1978–1988 to five in 2011–2012 (Ingersoll, Merrill, & Stuckey, 2014). And, nearly half of all teachers leave within five years costing U.S. public schools 2.6 billion dollars annually (Alliance for Excellent Education [AEE], 2004). These trends in the teaching workforce have important implications for school …

Children As A Reserve Labor Force, David F. Lancy

Sociology, Social Work and Anthropology Faculty Publications

Human life history is unique in the great length of the juvenile or immature period. The lengthened period is often attributed to the time required for youth to master the culture, particularly subsistence and survival skills. But an increasing number of studies show that children become skilled well before they gain complete independence and the status of adults. It seems, as they learn through play and participation in the domestic economy, children are acquiring a “reserve capacity” of skills and knowledge, which they may not fully employ for many years. The theory offered here to resolve this paradox poses that, …

Lovers And Mothers In Antonio García Gutiérrez’S El Trovador, Christine Blackshaw-Naberhaus

Decimonónica

Since the emergence of feminist literary criticism over four decades ago, scholars have been posing “new questions about old texts” (Tuttle 184), and in the field of Nineteenth- Century Spanish studies, questions Bridget Aldaraca, Lou Charnon-Deutsch, Catherine Jagoe, Susan Kirkpatrick, Jo Labanyi, Linda Materna and Karen Rauch have advanced continue to inform our understanding of gender discourse in nineteenth-century Spain. More specifically, Labanyi, Kirkpatrick, and Materna have elucidated how Spanish Romantic plays “dramatize the contradictions inherent in liberal individualism” (Labanyi 8). In their assessment, the progressive ideological project of the early nineteenth century, while endeavoring to expand forms of self-expression …

4 Help Non-Thirsty Natives Feel at Home

Cultivating native plants that have evolved to thrive in dry conditions could reduce the amount of water landscapes require. But natives can’t simply be uprooted from the foothills and deserts and plopped in the suburbs. Scientists are exploring which native plants have potential and working to bring them to a nursery near you (provided that “near you“ means in the arid West).

Managing water supplies well begins with knowing how much water you have. That’s more complex than measuring precipitation and runoff. It means considering water …

Eduarda Mansilla’S Mestizo Argentina: Orphanhood, Transnationalism, And Race In Lucía Miranda (1860), Sarah Moody

Decimonónica

The first known writing of the Lucía Miranda legend, a story of Argentine national origins, dates to 1612 with a work by Spanish soldier Ruy Díaz de Guzmán. Though apparently fictional, the episode appears as a chapter in an otherwise fact-based account of early European activity in the River Plate region known as La Argentina manuscrita.¹ Later writers reworked the legend in their own ways, adapting it to the circumstances of their own historical moment, but the consistent points of the storyline focus on irremediable interethnic conflict: Lucía was a young, virtuous Spanish woman who accompanied her husband …

Perceived Differences In Knowledge About Interactive Technology Between Young Adults And Their Parents, J. Mitchell Vaterlaus, Randall M. Jones, Sarah Tulane

Human Development and Family Studies Faculty Publications

This study was designed to investigate generational differences in knowledge about interactive technology (i.e., cell phones, social networking, email, video chat) between parents and their young adult children. Parents (n = 555) and young adults (n = 604) residing in the United States provided information about their knowledge in the use of interactive technology. Young adult children also reported their perceptions of their parents’ technological knowledge for the various technologies. Comparisons of young adult self-reported technological knowledge and their parents’ own reports of technological knowledge revealed that young adults were perceived to be much more knowledgeable than their parents (by …

Strong Recruitment From Sparse Plug Plantings Of Native California Bunchgrasses, Truman P. Young, Kari E. Veblen

Wildland Resources Faculty Publications

Grassland restoration efforts in California include plug planting or direct seeding of native perennial grasses. These plantings are usually installed at densities intended to achieve full cover of mature plants from the planted individuals, not relying on recruitment of their progeny. Recruitment of future generations would both be reassuring for the long-term success of projects and an indication that lower density plantings might be sufficient, but restoration monitoring rarely looks for recruitment in later years (see Morgan 1999).

Lichen Monitoring Delineates Biodiversity On A Great Barrier Reef Coral Cay, Paul C. Rogers, Roderick W. Rogers, Anne Hedrich, Patrick T. Moss

Wildland Resources Faculty Publications

Coral islands around the world are threatened by changing climates. Rising seas, drought, and increased tropical storms are already impacting island ecosystems. We aim to better understand lichen community ecology of coral island forests. We used an epiphytic lichen community survey to gauge Pisonia (Pisonia grandis R.BR.), which dominates forest conditions on Heron Island, Australia. Nine survey plots were sampled for lichen species presence and abundance, all tree diameters and species, GPS location, distance to forest-beach edge, and dominant forest type. Results found only six unique lichens and two lichen associates. A Multi-Response Permutation Procedures (MRPP) test found statistically distinct …

Trust In Science And Scientists And The Acceptance Of Evolution, Louis S. Nadelson

Teacher Education and Leadership Faculty Publications

Background: Accepting the concept of evolution is important for the advancement of biological science and has many implications for daily life. However, a large portion of the general public does not currently accept biological evolution. Therefore, it is important to understand what factors are associated with a decline in the acceptance of evolution. Of particular interest for us is the relationship of individuals’ sense of trust in science in relationship to evolution acceptance.

Methods: Using the Trust in Science and Scientists and Inventory of Student Evolution Acceptance we surveyed 159 undergraduate students enrolled in an introductory psychology course. Additionally, we …

Quaking Aspen At The Residential-Wildland Interface: Elk Herbivory Hinders Forest Conservation., Paul C. Rogers, Allison Jones, James Catlin, James Shuler, Arthur Morris, Michael R. Kuhns

Aspen Bibliography

T: Quaking aspen (Populus tremuloides) forests are experiencing numerous impediments across North America. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. Additionally, ecological tension zones are sometimes created at residential-wildland interfaces with divergent management directives. For example, private conservation reserves bordering public land may be degraded from browsing where game species find refuge from hunting and plentiful forage. We examined putative herbivore impacts to nearly pure aspen forests at Wolf Creek Ranch (WCR), a sparsely developed residential landscape in northern Utah. Forty-three one-hectare monitoring …

Altered Fire Regimes And The Persistence Of Quaking Aspen In The Rocky Mountains: A Literature Review, Aaron Rosenblum

Aspen Bibliography

The persistence of quaking aspen (Populus tremuloides Michx.) is of significant importance to land managers in the Rocky Mountain region. Fire suppression in the past century has been implicated as a mechanism influencing aspen population dynamics, as aspen are generally considered an early seral disturbance adapted species. The heterogeneity of aspen community assemblages and fire regimes makes it difficult to discern what the result of fire suppression has been at large spatial and temporal scales. Decision makers should investigate the questions at hand at the stand level in their study location to best determine the mechanisms at play, as well …

Long-Term Vegetation Change In Utah's Henry Mountains: A Study In Repeat Photography, Charles E. Kay

Aspen Bibliography

An extensive search was conducted of archival and other sources to locate as many historical photographs as possible for the Henry Mountains in south-central Utah. Those images were then taken into the field, the original camera stations relocated, and modern pictures made of the historical scenes to evaluate long-term vegetation change and land management activities. In all, 626 repeat photo sets were compiled—608 by the author and 18 by Earl Hindley. This book includes 126 photo sets that were representative of the areas studied.

Regeneration Dynamics Of White Spruce, Trembling Aspen, And Balsam Poplar In Response To Disturbance, Climatic, And Edaphic Factors In The Cold, Dry Boreal Forests Of The Southwest Yukon, Canada, Shyam K. Paudel, Craig R. Nitschke, Suzanne W. Simard, John L. Innes

Aspen Bibliography

The southwestern region of the Yukon Territory of Canada has experienced an unprecedented spruce bark beetle outbreak (Dendroctonus rufipennis) and an increase in the frequency of forest fires that extend beyond historical trends and that have caused significant impacts on forest structure and composition. A Strategic Forest Management Plan (SFMP) for the Champagne and Aishihik Traditional Territory located in the southwest Yukon was implemented in 2004 in response to the spruce bark beetle (D. rufipennis) infestation and increased fire risk. The plan has recommended salvage harvesting of beetle-killed stands as a strategy to facilitate the development …
