Recent Developments In Heterologous Expression Of Cellulases Using The Pichia Pastoris Expression System: A Comprehensive Literature Review, Nazish Muzaffar, Abdur Raziq, Muhammad Waseem Khan, Niaz Muhammad Khan, Bushra Shahid, Anbareen Gul, Hayat Ullah

Biological Engineering Student Research

Cellulosic biomass is considered an important and sustainable source of renewable energy, which needs a complex mixture of different enzymes for its degradation. After amylase, cellulases are the second most important enzymes, gain more importance due to their broad range of applications at the industrial level, and are considered more economical and environmentally friendly; researchers have focused more on the production of cellulase with its higher expression rate and low cost. Pichia pastoris, a methylotrophic yeast strain, has a more effective and well-established system for the production of heterologous proteins, particularly for industrial enzymes. Moreover, its readily achievable high-density …

Though freshwater harmful algal blooms have been described and studied for decades, several important dynamics remain uncertain, including the relationships among nutrient concentrations, phytoplankton growth, and cyanotoxin production. To identify when and where nutrients limit phytoplankton, cyanobacteria, and cyanotoxins, we conducted in situ bioassay studies. We added nitrogen (N), phosphorus (P), or N + P across various seasons in water collected from three locations across Utah Lake, one of the largest freshwater lakes in the western U.S. This shallow, hypereutrophic lake provides a powerful testbed for quantifying nutrient-growthtoxin interactions. We assessed a range of parameters over time, including photopigment concentrations, …

Drought Resilience And Legacy Effects In Two Forest Tree Species On Loess Plateau Of China: Growth And Water-Use Efficiency Under Different Drought Conditions, Lu Han, J. Julio Camarero, Guodong Jia, Zhiqiang Zhang, Lixin Chen

Aspen Bibliography

As droughts become more frequent and severer, understanding tree resilience and its role in mediating drought legacy effects (LEs) is critical for predicting forest ecosystem responses to future droughts and informing forest management. Both Pinus tabuliformis and Populus davidiana are widely distributed in the Loess Plateau region of western China and play important roles in provision of ecosystem services. In this study we quantified the LEs and resilience, including resistance (Rt) and recovery (Rc), of radial growth (BAI, basal area increment) and intrinsic water use efficiency (iWUE) of the two species, determined the external and internal factors influencing Rt and …

Exploring The Validity Of Adolescent Responses To A Measure Of Psychological Flexibility And Inflexibility, Caleb D. Farley, Tyler L. Renshaw

Psychology Student Research

Validating measures of psychological flexibility (PF) and psychological inflexibility (PI) has occurred in multiple adult samples, but little research has validated PF and PI measures with adolescents. This manuscript describes two studies exploring the validity of responses to the Multidimensional Psychological Flexibility Inventory (MPFI) with two samples of adolescents. The first study used exploratory factor analyses on responses to the MPFI with a sample of 16–17-year-olds (N = 249). The results yielded a reduced and simplified measurement model that consisted of two general factors: one for PF and the other for PI. These exploratory findings were further investigated with …

Restore The Shore: A Guide To Lakeshore Revegetation In The Great Basin, Jes V. Braun, Rae Robinson, Annie L. Henry, Karin M. Kettenring

All Current Publications

Lakeshore vegetation supports many valuable aspects of lake ecosystems: foraging areas for birds, rearing grounds for fish, nutrient cycling, carbon storage, and aesthetic, cultural, and spiritual values. Yet, the vegetation of many lakeshores has been lost or heavily impacted by humans. What can be done to restore lakeshore vegetation to ensure that lakes remain healthy for future generations? In this guide, we summarize best practices for lakeshore revegetation (i.e., the process of actively reintroducing vegetation, usually native species, to a restoration site through seeding and planting) in the Great Basin.

Journal of Indigenous Research

The growth of indigenous research methodologies and calls for data sovereignty are reshaping the discourse around evidence-based policymaking. This article summarizes the development and validation of the ‘Imi Pono Hawai‘i Wellbeing Survey, which examines wellbeing from indigenous, holistic, and strengths-based perspectives. The survey is anchored to a Kanaka Maoli (Native Hawaiian) model of wellbeing created through a community-participatory process involving diverse stakeholders. Early results show Native Hawaiians to be major contributors to Hawai‘i’s wellbeing, consistently reporting higher rates than non-Hawaiians for civic engagement, family relationships, and spirituality, as well as connections to culture, ‘āina, and community. This project informs strategic …

Relative Vulnerability Of Juvenile June Sucker To White Bass Predation In Utah Lake, Austin Garner, Kevin Landom, Rae Fadlovich, Timothy E. Walsworth

Watershed Sciences Student Research

Introduced species are one of the leading causes of native fish population declines globally, and predation by introduced species can impact native fish abundance, growth, and survival. In Utah Lake, many nonnative predators have been intentionally introduced over the past century to promote recreational fishing, including White Bass (Morone chrysops), one of the most abundant species in the system. June Suckers (Chasmistes liorus) are endemic to Utah Lake, but have experienced severe declines in abundance due to a combination of historical overexploitation, habitat degradation, and the introduction of nonnative fishes. Previous studies have indicated that first-year …

Shifting The Paradigm With Wednesday Addams: An Intersectional Analysis Of The First (Autistic) Female Latinx Detective, Camille Bassett, Jason Gilmore

Communication Studies and Philosophy Student Research

For centuries, Autistic people have been portrayed in media through two dehumanizing stereotypes, the robot and the superhuman savant. Together, the robot and the superhuman savant combine into one of the most popular hybrid stereotypes to appear in media: the detective. Past detectives have been almost exclusively white male characters, a longstanding pattern that erases Autistic women and people of color, among others. In 2022, however, Netflix’s spinoff series of The Addams Family, Wednesday, brought to the screen the first-ever female Latinx detective. This study is a thematic analysis of Wednesday as a character, the autism …

Modeling Vulnerability Of Juvenile June Sucker To The Piscivore Community In Utah Lake, Austin Garner, Kevin Landom, Rae Fadlovich, Timothy E. Walsworth

Watershed Sciences Student Research

Freshwater fish have experienced the highest extinction among all North American vertebrates, with interactions with introduced species among the leading factors of freshwater fish declines. In Utah Lake, effective hatchery stocking efforts have allowed the spawning abundance of threatened June sucker (Chasmistes liorus) to increase substantially over the past decade. Yet, recruitment of wild-spawned individuals remains very limited. A recent survivorship study of June sucker found individuals < 300mm experienced exceptionally poor survival, indicating a recruitment bottleneck persists despite significant recovery efforts. Current recovery efforts of Utah Lake have broadly targeted habitat improvement; However, prior studies have shown that large predation pressures by nonnatives have achieved recruitment bottlenecks in closely related species, suggesting predation could be limiting recovery efforts. Therefore, failure to address these pressures, if present, would result in overall recovery failure. Furthermore, predator management has focused on targeting Invasive Northern Pike (Esox Lucius) for potential impacts on June sucker. However, the impacts of more abundant nonnative piscivores remain largely unspecified.

Here, we use a simulation approach based on empirical data to …

A Machine Learning Model To Predict Wildfire Burn Severity For Pre-Fire Risk Assessments, Utah, Usa, Kipling B. Klimas, Larissa L. Yocom, Brendan P. Murphy, Scott R. David, Patrick Belmont, James A. Lutz, R. Justin Derose, Sara A. Wall

Wildland Resources Student Research

Background

High-severity burned areas can have lasting impacts on vegetation regeneration, carbon dynamics, hydrology, and erosion. While landscape models can predict erosion from burned areas using the differenced normalized burn ratio (dNBR), post-fire erosion modeling has predominantly focused on areas that have recently burned. Here, we developed and validated a predictive burn severity model that produces continuous dNBR predictions for recently unburned forest land in Utah.

Results

Vegetation productivity, elevation, and canopy fuels were the most important predictor variables in the model, highlighting the strong control of fuels and vegetation on burn severity in Utah. Final model out-of-bag R^{2 …}

Wildland Resources Faculty Publications

Rapid increases in wildfire area burned across North American forests pose novel challenges for managers and society. Increasing area burned raises questions about whether, and to what degree, contemporary fire regimes (1984–2022) are still departed from historical fire regimes (pre-1880). We use the North American tree-ring fire-scar network (NAFSN), a multi-century record comprising > 1800 fire-scar sites spanning diverse forest types, and contemporary fire perimeters to ask whether there is a contemporary fire surplus or fire deficit, and whether recent fire years are unprecedented relative to historical fire regimes. Our results indicate, despite increasing area burned in recent decades, that a …

Atsubp-2.0: An Integrated Web Server For The Annotation Of Arabidopsis Proteome Subcellular Localization Using Deep Learning, Naveen Duhan, Rakesh Kaundal

Plants, Soils and Climate Student Research

The organization of subcellular components in a cell is critical for its function and studying cellular processes, protein–protein interactions, identifying potential drug targets, network analysis, and other systems biology mechanisms. Determining protein localization experimentally is time-consuming and expensive. Due to the need for meticulous experimentation, validation, and data analysis, computational methods provide a quick and accurate alternative. Arabidopsis thaliana, a beneficial model organism in plant biology, facilitates experimentation and applies to other plants. Predicting its proteins' subcellular localization can improve our understanding of cellular processes and have applications in crop improvement and biotechnology. We propose AtSubP-2.0, an extension of …

Same Data, Different Analysts: Variation In Effect Sizes Due To Analytical Decisions In Ecology And Evolutionary Biology, Elliot Gould, Hannah S. Fraser, Timothy H. Parker, Shinichi Nakagawa, Simon C. Griffith, Peter A. Vesk, Fiona Fidler, Daniel G. Hamilton, Robin N. Abbey-Lee, Jessica K. Abbott, Erica F. Stuber, Et Al.

Wildland Resources Faculty Publications

Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among researchers in the decisions they make regarding statistical analyses. A growing array of studies has explored this analytical variability in different fields and has found substantial variability among results despite analysts having the same data and research question. Many of these studies have been in the social sciences, but one small “many analyst” study found similar variability in ecology. We expanded the scope …

Online propagation protocols, books on plant propagation, and other Utah State University (USU) Extension resources discuss how to start other unique and less common plants.

Starting Vegetable Seeds Indoors: I. Planning, Wesley Crump, Taun Beddes, Michael Caron, Milena Oliveira

All Current Publications

For many Utah gardeners, starting vegetable seeds indoors offers both an exciting opportunity to experiment with new varieties and a practical necessity for ensuring the successful growth and production of certain crops in their unique environmental conditions. Vegetable gardening involves inherent risks, particularly for the plants, with weather being a significant and largely uncontrollable factor. Because of this, many gardeners are unsure about when to start certain crops and whether the crops should be started indoors or sown directly in the garden. This fact sheet, the first in a series of four, discusses planning considerations when starting seeds indoors.
