As climate change intensifies, extreme weather increasingly threatens California’s Central Valley (CV), a vital agricultural region exposed to rising risks from heatwaves (HW), droughts (DR), and compound extremes. These events disrupt crop productivity and broader processes like water demand, pest dynamics, and soil stability, posing systemic risks. This study examines the spatiotemporal dynamics of HW, coldwaves (CW), DR, excessive rainfall (ER), and their compound (e.g., HWDR) and cascading forms from 1951 to 2025, using NOAA nClimGrid-Daily data. We assessed trends in frequency, intensity, and duration over long-term (1951–2025) and mid-term (1981–2025) periods. Results show increasing HW and DR in the …

Visualization Of Lysosomal Membrane Proteins By Cryo Electron Tomography, Bridget M Mcveigh, José J De Jesús-Pérez, Dirk H Siepe, Prerana Gogoi, Shrawan Kumar Mageswaran, Marian Kalocsay, Elaine M Mihelc, Vera Y Moiseenkova-Bell

Faculty, Staff and Student Publications

Lysosomes are essential organelles for cellular homeostasis and signaling, with dysfunction linked to neurological disorders, lysosomal storage diseases, and cancer. While proteomics has advanced our understanding of lysosomal composition, the structural characterization of lysosomal membrane proteins in their native environment remains a significant challenge. Here, we developed a cryo electron tomography workflow to visualize lysosomal membrane proteins within intact, native lysosomal membranes. We isolated endolysosomes by independently targeting two lysosomal membrane proteins, transient receptor potential mucolipin 1 and transmembrane protein 192, enriching organelles that exhibited the expected morphology and proteomic composition of the endolysosomal system. Sub-tomogram averaging enabled the structural …

Entomology and Plant Pathology Faculty Publications and Presentations

Bacillus subtilis is applied as a biofertilizer, biocontrol agent, and probiotic in agriculture, and is also used for industrial synthesis of proteins and peptides. These applications can be combined by using B. subtilis to synthesize plant health-promoting peptides in culture or to deliver them to roots via seed treatments. To facilitate the use of B. subtilis as a cell factory, we tested different media, temperatures, and growth phases to optimize ectopic expression of a Plant Elicitor Peptide from soybean (GmPEP3) that enhances seedling growth. Our results indicate that temperature, culture media, and growth phase have interactive effects, and that 30 …

Pilot Study: Integrating The Epic Stroke Narrator Into Inpatient Code Stroke Protocols To Improve Symptom Onset Identification And Reduce Intervention Times, Stacy L. Carter

Doctoral Dissertations and Projects

In-hospital strokes are often underrecognized, leading to treatment delays and poorer outcomes compared to community-onset strokes. This scholarly project evaluated whether integrating the Epic Stroke Narrator into inpatient code stroke protocols could improve documentation of last known well time (LKWT) and reduce time to intervention. A 6-week quasi-experimental pilot study guided by the Iowa Model of Evidence-Based Practice and Rogers’ diffusion of innovations theory was conducted on a neuroscience telemetry step-down unit at a comprehensive stroke center in Richmond, Virginia.

Robust Regression Rescues Poor Phylogenetic Decisions, Mataya Duncan, Michael Degiorgio, Raquel Assis, Richard Adams

Entomology and Plant Pathology Faculty Publications and Presentations

Comparative biology seeks to unlock the power of cross-species trait variation to learn the rules of life. In this venture, modern studies increasingly leverage large datasets spanning many traits and levels of biological organization and complexity. To analyze these complex data in a statistically-sound manner, researchers must choose a phylogeny that is assumed to model the mean trait values across species-an assumption that may be tenuous depending on the true evolutionary architecture of the traits. Yet the consequences of this decision remain poorly understood, particularly for modern studies seeking to analyze multiple, distinct traits within the same framework. Here, we …

Limb Regeneration In Damselflies Based On Developmental Stage, Haven O. Clements

Inquiry: The University of Arkansas Undergraduate Research Journal

Injury is common in wild animals, yet some species possess an adaptive advantage: regeneration. Enallagma vesperum, a species of damselfly, exhibits this regenerative ability, though its persistence and effectiveness across developmental stages remain poorly understood. While previous studies indicate that regeneration ceases following adult emergence, it is unclear whether this ability also diminishes prior to the final larval molt. This study investigated the effectiveness of limb regeneration in E. vesperum across early and late larval instars. I hypothesized that earlier instars would exhibit greater regenerative success due to fewer competing energetic demands compared to later instars, which may prioritize …
