Genetic improvement toward optimized and stable agronomic performance of soybean genotypes is desirable for food security. Understanding how genotypes perform in different environmental conditions helps breeders develop sustainable cultivars adapted to target regions. Complex traits of importance are known to be controlled by a large number of genomic regions with small effects whose magnitude and direction are modulated by environmental factors. Knowledge of the constraints and undesirable effects resulting from genotype by environmental interactions is a key objective in improving selection procedures in soybean breeding programs. In this study, the genetic basis of soybean grain yield responsiveness to environmental factors …

Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, Eileen Hebets, Melissa Welch-Lazoritz, Pawl Tisdale, Patricia Wonch Hill

Eileen Hebets Publications

Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

Discovery Orientation, Cognitive Schemas, And Disparities In Science Identity In Early Adolescence, Patricia Wonch Hill, Julia Mcquillan, Amy Spiegel, Judy Diamond

Department of Sociology: Faculty Publications

Why are some youth more likely to think of themselves as a science kind of person than others? In this paper, we use a cognitive social-theoretical framework to assess disparities in science identity among middle school–age youth in the United States. We investigate how discovery orientation is associated with science interest, perceived ability, importance, and reflected appraisal, and how they are related to whether youth see themselves, and perceive that others see them, as a science kind of person. We surveyed 441 students in an ethnically diverse, low-income middle school. Gender and race/ethnicity are associated with science identity but not …

Eigenstrain As A Mechanical Set-Point Of Cells, Shengmao Lin, Marsha C. Lampi, Cynthia A. Reinhart-King, Gary C.P. Tsui, Jian Wang, Carl A. Nelson, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

Cell contraction regulates how cells sense their mechanical environment. We sought to identify the set-point of cell contraction, also referred to as tensional homeostasis. In this work, bovine aortic endothelial cells (BAECs), cultured on substrates with different stiffness, were characterized using traction force microscopy (TFM). Numerical models were developed to provide insights into the mechanics of cell–substrate interactions. Cell contraction was modeled as eigenstrain which could induce isometric cell contraction without external forces. The predicted traction stresses matched well with TFM measurements. Furthermore, our numerical model provided cell stress and displacement maps for inspecting the fundamental regulating mechanism of cell …

Internet Of Underground Things: Sensing And Communications On The Field For Precision Agriculture, Mehmet C. Vuran, Abdul Salam, Rigoberto Wong, Suat Irmak

School of Computing: Conference and Workshop Papers

The projected increases in World population and need for food have recently motivated adoption of information technology solutions in crop fields within precision agriculture approaches. Internet of underground things (IOUT), which consists of sensors and communication devices, partly or completely buried underground for real-time soil sensing and monitoring, emerge from this need. This new paradigm facilitates seamless integration of underground sensors, machinery, and irrigation systems with the complex social network of growers, agronomists, crop consultants, and advisors. In this paper, state-of-the-art communication architectures are reviewed, and underlying sensing technology and communication mechanisms for IOUT are presented. Recent advances in the …

Molecular Gut-Content Analysis Reveals High Frequency Of Helicoverpa Zea (Lepidoptera: Noctuidae) Consumption By Orius Insidiosus (Hemiptera: Anthocoridae) In Sweet Corn, Julie A. Peterson, E. C. Burkness, James D. Harwood, W. D. Hutchison

Department of Entomology: Faculty Publications

Management of corn earworm Helicoverpa zea in sweet corn grown for processing can be challenging due to the lack of effective transgenic and chemical control options. However, biological control by generalist predators can provide a significant impact on pests in this cropping system. One of the most ubiquitous predators of H. zea and other lepidopterans is the insidious flower bug, Orius insidiosus. This small hemipteran has been observed as an important mortality agent of H. zea in several cropping systems, but the strength of the trophic connection between these species has not been documented in sweet corn. Molecular gut-content …

The Evolving Institutional Repository Landscape, Judy Luther

Copyright, Fair Use, Scholarly Communication, etc.

Advances in technology affecting content creation and digital dissemination continue to reshape the role of academic libraries. The impact of these changes requires reimagining a strategy for the library built around digital collections–not only those acquired from publishers but the growing variety of files created in the development of scholarship and learning. Institutional Repositories (IRs) are emerging as a vehicle for new directions in how libraries can support the academic community both locally and globally.

To gain insights and gather data on IR operations, we conducted interviews, an open survey, and web research to obtain a snapshot of the current …

The Trichoptera Of Panama V. Descriptions Of New Species, New Country Records, And A Synonymy, Brian J. Armitage, Steven C. Harris

Insecta Mundi

The Río Chiriqui basin is one of 52 major watershed areas, or cuencas, in the Republic of Panama. It occurs in western Panama, discharges into the Pacific Ocean, and includes portions of Volcán Barú on its northern extent. The Río Caldera occupies the northernmost subbasin of this basin. Two of its tributaries, Que­brada Grande and Quebrada Jaramillo, occur in close proximity and on opposite sides, and have different recent geologic histories and current land use patterns. During the course of investigating the caddisfly fauna of these two drainages, three new species of the microcaddisfly genus Neotrichia Morton (Trichoptera: Hydroptilidae) were …

A New Genus, A New Species, New Combinations, And Notes On Synonymy And Nomenclature In American Desmiphorini (Coleoptera, Cerambycidae, Lamiinae), Antonio Santos-Silva, James E. Wappes

Insecta Mundi

An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synony­mized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico …

Evaluation Of Acoustic Telemetry Grids For Determining Aquatic Animal Movement And Survival, Richard T. Kraus, Christopher M. Holbrook, Christopher S. Vandergoot, Taylor R, Stewart, Matthew D. Faust, Douglas A. Watkinson, Colin Charles, Mark A. Pegg, Eva C. Enders, Charles C. Krueger

School of Natural Resources: Faculty Publications

1. Acoustic telemetry studies have frequently prioritized linear configurations of hydrophone receivers, such as perpendicular from shorelines or across rivers, to detect the presence of tagged aquatic animals. This approach introduces unknown bias when receivers are stationed for convenience at geographic bottlenecks (e.g. at the mouth of an embayment or between islands) as opposed to deployments following a statistical sampling design.

2. We evaluated two-dimensional acoustic receiver arrays (grids: receivers spread uniformly across space) as an alternative approach to provide estimates of survival, movement and habitat use. Performance of variably spaced receiver grids (5–25 km spacing) was evaluated by simulating …

A High Throughput Approach For The Generation Of Orthogonally Interacting Protein Pairs, Justin Lawrie, Xi Song, Wei Niu, Jiantao Guo

Department of Chemistry: Faculty Publications

In contrast to the nearly error-free self-assembly of protein architectures in nature, artificial assembly of protein complexes with pre-defined structure and function in vitro is still challenging. To mimic nature’s strategy to construct pre-defined three-dimensional protein architectures, highly specific proteinprotein interacting pairs are needed. Here we report an effort to create an orthogonally interacting protein pair from its parental pair using a bacteria-based in vivo directed evolution strategy. This high throughput approach features a combination of a negative and a positive selection. The newly developed negative selection from this work was used to remove any protein mutants that retain effective …

Long-Term Monitoring Of Scripps’S Murrelet And Guadalupe Murrelet At San Clemente Island, California: Evaluation Of Baseline Data In 2012–2016, Darrell L. Whitworth, Harry R. Carter, Michael W. Parker, Franklin Gress, Melissa Booker

United States Navy: Publications

San Clemente Island (SCI) supports one of the smallest Scripps’s Murrelet (Synthliboramphus scrippsi; SCMU) colonies in the world, and perhaps the only colony of Guadalupe Murrelets (S. hypoleucus; GUMU) in California. In 2012–2016, the U.S. Navy sponsored development of a long-term murrelet monitoring program at SCI that utilized nocturnal spotlight surveys, night-lighting at-sea captures, and nest monitoring. Standardized spotlight survey transects were established in nearshore waters off breeding areas at Seal Cove and southeast SCI (SESCI). Baseline mean spotlight counts were 29 ± 15 murrelets (n = 31) at Seal Cove in 2013–2016 and …

Feeding Immunity: Physiological And Behavioral Responses To Infection And Resource Limitation, Sarah A. Budischak, Christina B. Hansen, Quentin Caudron, Romain Garnier, Tyler R. Kartzinel, István Pelczer, Clayton E. Cressler, Anieke Van Leeuwen, Andrea L. Graham

School of Biological Sciences: Faculty Publications

Resources are a core currency of species interactions and ecology in general (e.g., think of food webs or competition). Within parasite-infected hosts, resources are divided among the competing demands of host immunity and growth as well as parasite reproduction and growth. Effects of resources on immune responses are increasingly understood at the cellular level (e.g., metabolic predictors of effector function), but there has been limited consideration of how these effects scale up to affect individual energetic regimes (e.g., allocation trade-offs), susceptibility to infection, and feeding behavior (e.g., responses to local resource quality and quantity). We experimentally rewilded laboratory mice (strain …

Electron Effective Mass In Sn-Doped Monoclinic Single Crystal B-Gallium Oxide Determined By Mid-Infrared Optical Hall Effect, Sean Knight, Alyssa Mock, Rafal Korlacki, Vanya Darakchieva, Bo Monemar, Yoshinao Kumagai, Ken Goto, Masataka Higashiwaki, Mathias Schubert

Department of Electrical and Computer Engineering: Faculty Publications

The isotropic average conduction band minimum electron effective mass in Sn-doped monoclinic single crystal B-Ga₂O₃ is experimentally determined by the mid-infrared optical Hall effect to be (0.28460.013)m₀ combining investigations on (010) and (_201) surface cuts. This result falls within the broad range of values predicted by theoretical calculations for undoped B-Ga₂O₃. The result is also comparable to recent density functional calculations using the Gaussian-attenuation- Perdew-Burke-Ernzerhof hybrid density functional, which predict an average effective mass of 0.267m₀. Within our uncertainty limits, we detect no anisotropy for the electron effective mass, which …

Into The Void, Or The Musings And Confessions Of A Redheaded Stepchild Lost In Western Legal History And Found In The Legal Borderlands Of The North American West, Katrina Jagodinsky

At my first American Society for Legal History conference in 2014, I listened with rapt attention as keynote speaker Patty Limerick asked: "Is western history legal history ?" Limerick answered in the affirmative, citing the many ways in which law had defined the North American West. Those of us who teach Western history courses can count the legal acts Limerick recited on our fingers and toes: the 1784 Land Ordinance, the 1787 Northwest Ordinance, the 1790 Trade & Intercourse Act, the 1803 Louisiana Purchase, and every treaty between American Indians and the federal government on one hand; the Missouri Compromises …

Antral Follicular Count Is A Tool That May Allow The Selection Of More Precocious Bradford Heifers At Weaning, R. Santa Cruz, R. A. Cushman, C. Viñoles

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Although antral follicle count is a repeatable parameter across life that is positively associated with fertility, its use at weaning as a tool to discard less fertile heifers has not been extensively evaluated. The hypotheses of this work are: 1) maximum antral follicle count (MAFC) is repeatable between weaning and pre breeding evaluations, allowing selection of more fertile heifers at an early age, 2) heifers with high MAFC have growth and development parameters linked to an earlier puberty and pregnancy, 3) MAFC has a positive correlation with AMH concentrations, so that both could be used inter changeably. In this study, …

Spermidine-Regulated Biosynthesis Of Heat-Stable Antifungal Factor (Hsaf) In Lysobacter Enzymogenes Oh11, Yuan Chen, Fengquan Liu, Liangcheng Du

Liangcheng Du Publications

Heat-Stable Antifungal Factor (HSAF) and its analogs are antifungal natural products produced by the biocontrol agent Lysobacter enzymogenes. The production of HSAF is greatly influenced by environmental stimuli and nutrients, but the underlying molecular mechanism is mostly unclear. Here, we found that HSAF production in L. enzymogenes OH11 is strictly controlled by spermidine, which is the most prevalent triamine in bacteria. When added into OH11 cultures, spermidine regulated the production of HSAF and analogs in a concentration-dependent manner. To verify the role of spermidine, we deleted LeSDC and LeADC genes, encoding S-adenosylmethionine decarboxylase and arginine decarboxylase, respectively, that are the …
