Abalones At Risk: A Global Red List Assessment Of Haliotis In A Changing Climate, Howard Peters, Gina M. Ralph, Laura Rogers-Bennett

Biological Sciences Faculty Publications

There is increasing awareness that marine invertebrates such as abalones are at risk from the combined stressors of fishing and climate change. Abalones are an important marine fishery resource and of cultural importance to Indigenous and non-Indigenous people. A highly priced marine delicacy, they are inherently vulnerable: individuals are slow-growing and long-lived and successful reproduction requires dense assemblages. However, their global conservation status is poorly understood. Using IUCN Red List methodology, we assessed the extinction risk to all 54 species of abalone (genus Haliotis). Of the 21 fished commercially for human consumption either now and/or in the past, 15 …

Cyp6g2 Is The Major P450 Epoxidase Responsible For Juvenile Hormone Biosynthesis In Drosophila Melanogaster, Qiangqiang Jia, Liu Yang, Jiamin Wen, Suning Liu, Di Wen, Wei Luo, Weihua Wang, Subba R. Palli, Li Sheng

Entomology Faculty Publications

Background Juvenile hormones (JH) play crucial role in regulating development and reproduction in insects. The most common form of JH is JH III, derived from MF through epoxidation by CYP15 enzymes. However, in the higher dipterans, such as the fruitfly, Drosophila melanogaster, a bis-epoxide form of JHB3, accounted most of the JH detected. Moreover, these higher dipterans have lost the CYP15 gene from their genomes. As a result, the identity of the P450 epoxidase in the JH biosynthesis pathway in higher dipterans remains unknown.

Results In this study, we show that Cyp6g2 serves as the major JH epoxidase responsible for …

Go West: Population Genomics Reveals Unexpected Population Fluctuations And Little Gene Flow In Western Hemisphere Populations Of The Predatory Lady Beetle, Hippodamia Convergens, Arun Sethuraman, Schyler O. Nunziata, Angela Jones, John J. Obrycki, David W. Weisrock

Entomology Faculty Publications

Hippodamia convergens—the convergent lady beetle, has been used extensively in aug- mentative biological control of aphids, thrips, and whiteflies across its native range in North America, and was introduced into South America in the 1950s. Overwintering H. convergens populations from its native western range in the United States are com- mercially collected and released across its current range in the eastern USA, with little knowledge of the effectiveness of its augmentative biological control. Here we use a novel ddRADseq-based SNP/haplotype discovery approach to estimate its range- wide population diversity, differentiation, and recent evolutionary history. Our results indicate (1) significant population …

N(Alpha)-Acetyltransferase 40-Mediated Histone Acetylation Plays An Important Role In Ecdysone Regulation Of Metamorphosis In The Red Flour Beetle, Tribolium Castaneum, Sharath Chandra Gaddelapati, Smitha George, Anilkumar Moola, Karthi Sengodan, Subba Reddy Palli

Entomology Faculty Publications

Histone acetylation, a crucial epigenetic modification, is governed by histone acetyltransferases (HATs), that regulate many biological processes. Functions of HATs in insects are not well understood. We identified 27 HATs and determined their functions using RNA interference (RNAi) in the model insect, Tribolium castaneum. Among HATs studied, N-alpha-acetyltransferase 40 (NAA40) knockdown caused a severe phenotype of arrested larval development. The steroid hormone, ecdysone induced NAA40 expression through its receptor, EcR (ecdysone receptor). Interestingly, ecdysone-induced NAA40 regulates EcR expression. NAA40 acetylates histone H4 protein, associated with the promoters of ecdysone response genes: EcR, E74, E75, and HR3, and causes an increase …

The Mechanoreceptor Piezo Is Required For Spermatogenesis In Bombyx Mori, Zhongjie Zhang, Xiaojing Liu, Bo Hu, Kai Chen, Ye Yu, Chenxin Sun, Dalin Zhu, Hua Bai, Subba Reddy Palli, Anjiang Tan

Entomology Faculty Publications

Background The animal sperm shows high diversity in morphology, components, and motility. In the lepidopteran model insect, the silkworm Bombyx mori, two types of sperm, including nucleate fertile eupyrene sperm and anucleate unfertile apyrene sperm, are generated. Apyrene sperm assists fertilization by facilitating the migration of eupyrene spermatozoa from the bursa copulatrix to the spermatheca. During spermatogenesis, eupyrene sperm bundles extrude the cytoplasm by peristaltic squeezing, while the nuclei of the apyrene sperm bundles are discarded with the same process, forming matured sperm.

Results In this study, we describe that a mechanoreceptor BmPiezo, the sole Piezo ortholog in B. mori, …

Tree Species Richness And Ash Density Have Variable Effects On Emerald Ash Borer Biological Control By Woodpeckers And Parasitoid Wasps In Post-Invasion White Ash Stands, Caleb J. Wilson, Toby R. Petrice, Therese M. Poland, Deborah G. Mccullough

Entomology Faculty Publications

Emerald ash borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) is the most destructive insect to invade North American forests. Identifying habitat features that support EAB natural enemies is necessary to enhance EAB biological control. In many forest ecosystems, tree species diversity has been linked with reduced pest abundance and increases in natural enemy abundance. We assessed the influence of tree species richness, ash density, and proportion of total ash basal area on ash canopy condition, EAB larval densities, and biocontrol by woodpeckers and parasitoids in pairs of healthy and declining overstory (DBH > 10 cm) and recruit-sized ash (DBH 2–10 cm) …

Introduction (To Emotional Expressionism), E. Deidre Pribram Ph.D.

Communications: Faculty Publications

The primary purpose of Emotional Expressionism: Television Serialization, The Melodramatic Mode, and Socioemotionality is to explore the forms, functions, and nuances of emotions in popular, mediated narratives. Clearly, emotions constitute a key means by which audiences experience and make sense of narrative media, in that mediated stories make compelling arguments or take up resonant positions through their emotional methods and meanings. The value of developing an emotional template for screen media lies in generating new analytical and interpretative approaches to narrative aesthetics, especially in terms of their pains and pleasures. As this study seeks to demonstrate, emotional analysis opens up …

Abortion Pills: Us History And Politics, Carrie N. Baker

Open Educational Resources: Textbooks

This is the first book to offer a comprehensive history of abortion pills in the United States. Public intellectual and lawyer Carrie N. Baker shows how courageous activists waged a decades-long campaign to establish, expand, and maintain access to abortion pills. Weaving their voices throughout her book, Baker recounts both dramatic and everyday acts of their resistance. These activists battled anti-abortion forces, overly cautious policymakers, medical gatekeepers, and fearful allies in their four-decade-long fight to free abortion pills. In post-Roe America, abortion pills are currently playing a critically important role in providing safe abortion access to tens of thousands of …

Balancing Abortion, Ball, Carlos A.

Santa Clara Law Review

Critics of Roe v. Wade and its progeny repeatedly contended that, in recognizing a fundamental right to choose an abortion, the Supreme Court ignored or significantly undervalued the states’ interests in regulating abortions. This Article’s examina- tion of the Court’s abortion jurisprudence during the Roe era, however, shows how it called for a meaningful balancing of the interests of both sides in ways that led the justices to uphold roughly as many abortion laws as they struck down between 1973 and 2020. In exploring the crucial role that the balancing of the interests of both the state and pregnant individuals …

A Novel Scheme Based On Bessel Operational Matrices For Solving A Class Of Nonlinear Systems Of Differential Equations, Atallah El-Shenawy, Mohamed El-Gamel, Muhammad E. Anany

Mansoura Engineering Journal

The system of ordinary differential equations arises in many natural phenomena, especially in the field of disease spread. In this paper, a perfect spectral technique is introduced to solve systems of nonlinear differential equations. The technique enhanced the Bessel collocation technique by converting the series notation of unknown variables and their derivatives to matrix relations. The Newton algorithm is developed to solve the resulting nonlinear system of algebraic equations. The effectiveness of the scheme is proved by the convergence analysis and error bound as demonstrated in Theorem 1. The scheme of solution is tested to clarify the efficiency and the …

Mansoura Engineering Journal

The challenge of managing water resources is intensifying due to rapid urbanization, population expansion, and the growth of industry and agriculture. Furthermore, the looming threat of climate change significantly impacts both water resources and crop yields. In Kuwait, the majority of its potable water supply is dependent on seawater desalination. Specifically, multistage flash (MSF) desalination accounts for nearly 90% of the country's total desalination capacity, while the remaining 10% is generated using multi-effect distillation (MED) technology. Nevertheless, the environmental repercussions of desalination on Kuwait's ecosystem remain a subject of profound concern. This study employs a comprehensive approach, utilizing peer-reviewed journal …

Glaucoma Diagnosis Using Hybrid Neural Encoder Decoder Based Unet Hybrid Inception, Akanksha Bali, Vibhakar Mansotra

Mansoura Engineering Journal

The anatomy of the retinal fundus picture, which includes the optic disc, affects how glaucoma characteristics are extracted. One of the main causes of blindness in the globe is glaucoma. Correct glaucoma screening in its early phases is difficult since the condition only becomes apparent when its symptoms are severe. If glaucoma is not treated, the optic nerve head (ONH) will be harmed, resulting in vision loss. Nevertheless, there are currently not enough eye experts accessible, and eye screening is personal, time-consuming and labor-intensive. Therefore, this is a real issue that can be addressed by automatically diagnosing glaucoma using deep …

The goal of this study is to investigate the survival time of transplanted kidneys from 1987 to 2018 regarding the donors’ and the recipients’ characteristics. Survival analysis is performed to determine the characteristics associated …

No Orthopathy Without Orthoaesthesis: On The Necessity Of Negative Effort, Ryan G. Duns

Theology Faculty Research and Publications

Theologians have become increasingly attentive to the role emotion and experience must play in theological reflection. Several thinkers have recently done so by appropriating and developing Jon Sobrino’s understanding of orthopathy, or “right affect.” A close examination of these efforts, however, reveals inconsistencies in the way the category is understood and deployed. This article redresses these inconsistencies by complementing orthopathy with orthoaesthesis, or “right perception.” The article opens by considering various appeals to orthopathy before suggesting how William James’s theory of emotion might provide the category with clarifying content. The second stage engages Simone Weil and Iris Murdoch as practitioners …

Human Cell Modeling Of Cdkl5-Deficiency Disorder With Patient-Derived Organoids And Hd-Mea, Alyssa Paynton

Cal Poly Humboldt theses and projects

CDKL5 deficiency disorder (CDD) is an X-linked disorder that leads to severe cognitive impairments as well as infantile epilepsy. The only FDA approved therapy helps to reduce seizure frequency, however there are currently no cures approved. While murine models have proven useful in characterizing CDD, there are limitations due to differences in brain structure and development across species that may lead to the reported lack of spontaneous seizures in the mouse, a hallmark in humans affected by this disorder. By the utilization of patient-specific iPSCs generated into cerebral organoids, a more comprehensive and in-depth analysis into rare neurological disorders, such …

Illuminating Function And Enabling Inhibition At The Protein-Membrane Interface Of Glutathione Peroxidase 4., Courtney L. Labrecque

Theses and Dissertations

Membrane proteins act as gateways to cells and are responsible not only for signaling, lipid transport, and cellular homeostasis, but they are also integral in disease pathologies. One class of membrane proteins, peripheral membrane proteins (PMPs), reside in aqueous compartments of the cell until they are recruited to the membrane to perform their function. Glutathione peroxidase 4 (GPx4) is a PMP enzyme responsible for engaging the membrane and reducing lipid hydroperoxides, thereby preventing cellular death via ferroptosis. Due to its central function surrounding ferroptosis, GPx4 is an interesting drug target that has recently gained interest for inflammatory diseases as well …

Latent Profiles Of Child Coping And Perception Of Experience Processes To Predict Long-Term Symptoms Of Depression, Intrusive Grief, And Suicidality Outcomes In Parentally Bereaved Children, Rebecca Hoppe

Theses and Dissertations

Childhood bereavement is a significant public health issue and the most distressing form of childhood trauma. The death of a parent can disrupt the course of a children's development and potentially predispose them to enduring adverse mental health outcomes, such as depression, intrusive grief, and suicidality. Recognizing grief as a dynamic process, theories have suggested that children’s unique coping and perceptions of experience can contribute to variations in individual adaptations to the death and the onset of mental health problems. The goals of this study were to (a) use latent profile analysis to empirically group recently bereaved children into distinct …

Assessing Relocation Habitats And Assisted Migration Of The Lassics Lupine, An Endangered California Serpentine-Endemic, Caitlyn M. Allchin

Cal Poly Humboldt theses and projects

The Lassics lupine, Lupinus constancei, is a serpentine species endemic to the Lassics Mountains of northern California, listed as critically imperiled and federally endangered. Increased encroachment from reduced fire intervals has led to elevated herbivory from small mammals. While deployment of exclosure cages has decreased negative impacts, diminishing snowpack from shifting climate continues to threaten the Lassics lupine. To locate possible refugia, I evaluated alternative sites for assisted migration. I built a habitat suitability model (HSM) using MaxEnt software and WorldClim variables to predict optimal habitat. I then evaluated aerial imagery, topography, and geology to identify areas for microhabitat …

Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming

Cal Poly Humboldt theses and projects

This project explores the pathways by which agriculture affects the environment and determines which foods have the greatest climate, water, and land impacts. Agricultural effects on the environment are extensive, from loss of habitat and declines in regional biodiversity to disruption of global nutrient cycles and climate change. Global food production accounts for 26-34% of annual anthropogenic greenhouse gas emissions, makes up 38-46% of habitable land, and is responsible for 70% of freshwater extraction. The effect of agriculture on the environment is most significantly dictated by what type of food is being produced. Animal-based food products consistently have the highest …

Pond Characteristics That Influence Oviposition Site Selection By Two Pond-Breeding Amphibians, Northern Red-Legged Frog (Rana Aurora) And Northwestern Salamander (Ambystoma Gracile), Jessica Jones

Cal Poly Humboldt theses and projects

Pond-breeding amphibians connect aquatic and terrestrial habitats through their biphasic life cycle, and understanding pond characteristics that support oviposition sites for multiple species is important for amphibian conservation. Two common amphibians in the Pacific Northwest, Northern red-legged frog (Rana aurora) and Northwestern salamander (Ambystoma gracile) often oviposit in the same pond; however, prior studies have focused on pond use by one species or the other, but not both together. I surveyed pond and oviposition site characteristics of 26 ponds in Humboldt County, CA, 10 of which were used only by R. aurora and 16 of which …

Characterizing New Plant Fossils With Woody Growth From The Battery Point Formation Of Quebec (Canada), Emma T. Casselman

Cal Poly Humboldt theses and projects

The oldest woody growth has been recognized in several Early Devonian (ca. 410-395 Ma) euphyllophytes. Their taxonomic diversity is difficult to evaluate due to a lack of quantitative methods for comparing plants based on secondary xylem anatomy. In turn, this hinders understanding of their implications for the evolution of plant development. To develop metrics that quantify secondary xylem anatomy and allow for conclusive comparisons, I investigated extant taxa and Early Devonian fossil woody taxa. I developed multiple metrics for quantifying tracheid size as a function of position in the secondary xylem and tested them on a dataset of extant gymnosperms. …

A Post-Colonial Criticism Of Ernest Callenbach's Ecotopia, Kaitlyn R. O'Dell

Cal Poly Humboldt theses and projects

The representation of Indigenous land-based cosmologies within Ernest Callenbach’s Ecotopia communicates a real perception of our world through the constructed imaginative society within this speculative fiction novel. Ecotopia is an alternative Pacific West Coast society that counters the dominant United States model in its holistic and green approach. This green society relies heavily on Indigenous ideology but lacks actual Indigenous voices or communities within this white idealized society. This research provides an example of the deconstruction of this popular novel to its main problematic components, establishing why the use of Indigenous beliefs and values can cause negative implications to the …
