Fisheries Management Paper No. 276: Western Australian Silverlip Pearl Oyster (Pinctada Maxima) Resource Harvest Strategy 2022 - 2026, Version 2.0, Department Of Primary Industries And Regional Development, Western Australia

Fisheries Management Papers

Harvest strategies for aquatic resources in Western Australia (WA) are formal documents that support decision making processes which are consistent with the principles of Ecologically Sustainable Development (ESD; Fletcher 2002) and Ecosystem Based Fisheries Management (EBFM; Fletcher et al. 2012). The objectives of ESD are reflected in the Fish Resources Management Act 1994 (FRMA), Section 3, and the Aquatic Resources Management Act 2016 (ARMA), Section 9, which will replace the FRMA once enacted.

This Harvest Strategy aligns with DPIRD’s Harvest Strategy Policy for Aquatic Resources (Department of Fisheries 2015) and is consistent with national Harvest Strategy policies and guidelines (Sloan …

Characterization Of Severity In Zellweger Spectrum Disorder By Clinical Findings: A Scoping Review, Meta-Analysis And Medical Chart Review, Mousumi Bose, Christine Yergeau, Yasmin D’Souza, David D. Cuthbertson, Melisa J. Lopez, Alyssa K. Smolen, Nancy E. Braverman

Department of Nutrition and Food Studies Scholarship and Creative Works

Zellweger spectrum disorder (ZSD) is a rare, debilitating genetic disorder of peroxisome biogenesis that affects multiple organ systems and presents with broad clinical heterogeneity. Al-though severe, intermediate, and mild forms of ZSD have been described, these designations are often arbitrary, presenting difficulty in understanding individual prognosis and treatment effectiveness. The purpose of this study is to conduct a scoping review and meta-analysis of existing literature and a medical chart review to determine if characterization of clinical findings can predict severity in ZSD. Our PubMed search for articles describing severity, clinical findings, and survival in ZSD resulted in 107 studies (representing …

Narrating Agricultural Resilience After Hurricane María: How Smallholder Farmers In Puerto Rico Leverage Self-Sufficiency And Collaborative Agency In A Climate-Vulnerable Food System, Abrania Marrero, Andrea Lόpez-Cepero, Ramón Borges-Méndez, Josiemer Mattei

Sustainability and Social Justice

Climate change is a threat to food system stability, with small islands particularly vulnerable to extreme weather events. In Puerto Rico, a diminished agricultural sector and resulting food import dependence have been implicated in reduced diet quality, rural impoverishment, and periodic food insecurity during natural disasters. In contrast, smallholder farmers in Puerto Rico serve as cultural emblems of self-sufficient food production, providing fresh foods to local communities in an informal economy and leveraging traditional knowledge systems to manage varying ecological and climatic constraints. The current mixed methods study sought to document this expertise and employed a questionnaire and narrative interviewing …

Barrier Knockdown Test Control System For The Cal Poly Kinesiology Department, Regina M. Chapuis

Computer Engineering

The goal of this project is to design and implement a new control system for the LEDs and buttons on an existing Barrier Knockdown setup in the Cal Poly Kinesiology department. The Barrier Knockdown test is a testing apparatus in which subjects knock down a series of mechanical barriers in one of three patterns. The computer system times their reaction and movement time, and the test as a whole provides students with data to study the phenomenon of Contextual Interference. This system was previously controlled by an old computer setup that ultimately crashed. This project recreates the logic and user …

Faculty Research 2022

ABSTRACT: Identifying the genetic determinants of pain is a scientific imperative given the magnitude of the global health burden that pain causes. Here, we report a genetic screen for nociception, performed under the auspices of the International Mouse Phenotyping Consortium. A biased set of 110 single-gene knockout mouse strains was screened for 1 or more nociception and hypersensitivity assays, including chemical nociception (formalin) and mechanical and thermal nociception (von Frey filaments and Hargreaves tests, respectively), with or without an inflammatory agent (complete Freund's adjuvant). We identified 13 single-gene knockout strains with altered nocifensive behavior in 1 or more assays. All …

Remembering Lanny Randolph, William Flack

Nebraska Bird Review

Nebraska's birding community suffered a great loss on June 17, 2022, with the death of Lanny Randolph, an enthusiastic birder and a good friend to all of us. ... Lanny ... resolutely continued birding. In May 2022, he was able to attend the NOU meeting in Gering, and to see many of his longtime friends for the first time since the COVID pandemic. But a month later, on June 17, he was taken from us. Lanny's no longer physically present among us. But for those of us who knew him, he'll always be there in our memories, an invisible presence …

Spring Field Report, March-May 2022, W. Ross Silcock

Nebraska Bird Review

This spring there was a large number of interesting reports generated by active field observers, particularly in the west, where our knowledge continues to be broadened in all aspects. The main takeaway this spring was the inordinate plethora of species that matched or exceeded early arrival dates listed in BONO. There were no fewer than 70 species in this category, involving most families and genera, suggesting some overall influence on migration timing. Perhaps exceptions to these early arrivals were some lingering waterfowl and gulls although terns arrived early. Fully 50 of the early arrivers were passerines, notably including nine species …

Detecting Gold Mining Impacts On Insect Biodiversity In A Tropical Mining Frontier With Smallsat Imagery, Eric Stoll, Anand Roopsind, Gyanpriya Maharaj, Sandra Velazco, T. Trevor Caughlin

Biology Faculty Publications and Presentations

Gold mining is a major driver of Amazonian forest loss and degradation. As mining activity encroaches on primary forest in remote and inaccessible areas, satellite imagery provides crucial data for monitoring mining-related deforestation. High-resolution imagery, in particular, has shown promise for detecting artisanal gold mining at the forest frontier. An important next step will be to establish relationships between satellite-derived land cover change and biodiversity impacts of gold mining. In this study, we set out to detect artisanal gold mining using high-resolution imagery and relate mining land cover to insects, a taxonomic group that accounts for the majority of faunal …

Early Advanced Therapy For Diabetic Foot Ulcers In High Amputation Risk Veterans: A Cohort Study, Margaret Doucette, Kattie M. Payne, Walter Lough, Alison Beck, Kristi Wayment, John Huffman, Laura Bond, Aurora Thomas-Vogel, Susan Langley

Biomedical Research Institute Publications and Presentations

Veterans with diabetic foot ulcers (DFUs) represent the highest percentage of lower extremity amputations (LEAs) within the Veterans Affairs (VA) population. Many veterans have additional risk factors for amputation. Few studies focus on advanced therapies for this population. This study explores the impact of early application of dehydrated human amniotic membrane allograft (DAMA) with comprehensive care on preventing amputation. This prospective, single-center cohort study (ClinicalTrials.gov Identifier NCT02632929) was conducted through Boise VA Medical Center. Patients with DFUs were objectively stratified for LEA risk. Those with moderate to high amputation risk could participate. Participants received comprehensive care and weekly application of …

Specialized Named Entity Recognition For Breast Cancer Subtyping, Griffith Scheyer Hawblitzel

Master's Theses

The amount of data and analysis being published and archived in the biomedical research community is more than can feasibly be sifted through manually, which limits the information an individual or small group can synthesize and integrate into their own research. This presents an opportunity for using automated methods, including Natural Language Processing (NLP), to extract important information from text on various topics. Named Entity Recognition (NER), is one way to automate knowledge extraction of raw text. NER is defined as the task of identifying named entities from text using labels such as people, dates, locations, diseases, and proteins. There …

Understanding Rare Species In California: An Assessment Of Camatta Canyon Amole (Hooveria Purpurea Var. Reducta) And A Meta-Analysis Of California Rare Plants In Literature, Kieran N. Althaus

Master's Theses

California is currently in the midst of a biodiversity crisis. There are approximately 5,000 native species of plants in California, a quarter of which are considered rare. Determining threats to these rare plants is often times difficult. Despite California's botanical resources, we still know very little about much of California’s rare plants. San Luis Obispo County is home to 2,000 of California’s native plant taxa, one- third of which are rare or endemic to the county. These species are of great local and environmental concern.

In Chapter 1, we attempted to assess the impact of non native species on a …

Efficacy Of Chemical And Biological Stump Treatments For The Control Of Heterobasidion Occidentale Infection Of California Abies Concolor, Adrian Luis Poloni

Master's Theses

We conducted an experimental evaluation of treatments to limit Heterobasidion occidentale infection of white fir (Abies concolor) stumps and wounds in California mixed conifer forests. We tested the efficacy of urea, borate, and a mixture of two locally collected Phlebiopsis gigantea strains in preventing pathogen colonization of fir stumps and separately, urea and borate as infection controls on experimental stem wounds. These were paired with a laboratory test on ~100 g wood blocks with and without a one-week delay between inoculation and treatment. Urea, borates, and Phlebiopsis treatments all significantly reduced the stump surface area that was colonized …

The Effects Of Cofermentation Of Cider And Apple Pomace On Cider Attributes, Abigail D. Affonso

Master's Theses

Phenolics are critical to the sensory attributes and health benefits of hard cider due to their contribution to the flavor, mouthfeel, and antioxidant activity. With the increase in demand for cider, the use of dessert apple varieties has become more common leaving ciders lacking in phenolics. However, a promising method to increase their phenolic content is through maceration with apple pomace. This study evaluated the effect maceration with apple pomace during cider fermentation on the extraction of phenolic compounds, as well as its effect on the sensory properties of the final product. For this study, ciders were fermented with 0% …

Altered Collective Mitochondrial Dynamics In The Arabidopsis Msh1 Mutant Compromising Organelle Dna Maintenance, Joanna M. Chustecki, Ross D. Etherington, Daniel J. Gibbs, Iain G. Johnston

Department of Biochemistry: Faculty Publications

Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be fully elucidated. Here, we use a recently developed quantitative approach to reveal and analyse the physical and collective ‘social’ dynamics of mitochondria in an Arabidopsis msh1 mutant where the organelle DNA maintenance machinery is compromised. We use a newly created line combining the msh1 mutant with mitochondrially targeted green fluorescent protein (GFP), and characterize mitochondrial dynamics with a combination of single-cell time-lapse microscopy, computational tracking, and network …

Animal and Food Sciences Faculty Publications

Mixed sex pigs (n = 720) were placed in 12 rooms (Purdue Swine Environmental Research Building) to measure the effect of reduced crude protein (CP), amino acid (AA)-supplemented diets on growth and the carcass. Pigs were blocked by body weight (BW) and gender and allotted to room and pen (10 mixed-sex pigs/pen). Pigs were fed a nine-phase, wean-finish program. Control pigs consumed corn-soybean meal-distiller’s dried grains with solubles (DDGS) diets containing no to minimal (Met) synthetic AA. The 2X diet was formulated to meet the seventh most-limiting AA, and balanced using synthetic AAs to meet all AA needs. The 1X …

Highly Swellable Hydrogels Prepared From Extensively Oxidized Lignin, Jihyeon Hwang, Daniella V. Martinez, Estevan J. Martinez, Gift Metavarayuth, Dustin Goodlett, Qi Wang, Mitra Ganewatta, Michael S. Kent, Chuanbing Tang

Faculty Publications

Biopolymers such as lignin are gaining renewed appeal due to the need for sustainable materials. Herein, we used chelator-mediated Fenton (CMF) chemistry to oxidize Kraft lignin to develop sustainable super absorbent materials. The CMF chemistry adds oxygen, opens aromatic rings and increases COOH content, producing hydrophilic lignin without depolymerization. UV absorption, molecular weight, elemental analysis, and titration were used to study the chemical compositions of CMF-processed lignin. Then the chemically modified hydrophilic lignin was used to produce lignin-based hydrogels utilizing an aqueous polymerization and cross-linking reaction that enabled tunable properties. The resulting lignin hydrogels absorbed water up to 96% and …

Expression And Purification Of The Bacterial Protein Curli Csga And Its Cross-Interactions With Amyloid-B, Leah Grace Cantrell

Honors Theses

One of the main causes of neurodegenerative diseases is aggregation of amyloid proteins that are toxic to the neurons. Proteins like amyloid-β (Aβ) and α-syneuclein (α-syn) form hallmark aggregate lesions that contribute to pathological processes in the brain in Alzheimer and Parkinson’s patients, respectively. Recent ground-breaking studies have suggested a link between the microbiota of the gut and neurodegenerative diseases, called the “gut-brain axis.” It has been long known that the protein, CsgA found in many enteric bacteria, forms amyloid fibers of its own called Curli. Curli fibrils are a structural component of bacterial colonies and maintain the integrity of …

A Cross-Country Investigation Of Social Image Motivation And Acceptance Of Lab-Grown Meat In Singapore And The United States, Mark Chong, Angela K. Y. Leung, Verity Lua

Research Collection Lee Kong Chian School Of Business

This research has three goals. First, it sets out to compare consumer acceptance of lab-grown meat in the U.S. and in Singapore. Second, it seeks to explain the difference in Americans' and Singaporeans' acceptance of lab-grown meat by examining their eating motivations. Specifically, we focused on social image motivations – the motivations to present oneself positively in social contexts. Third, this study also aims to assess if exposure to information about lab-grown meat communicated by celebrity versus expert social media influencers (SMIs) can impact people's acceptance of lab-grown meat products. Our analysis showed that Singaporean participants had greater acceptance of …

Commodity Marketing For High School Students, Fabio Mattos

Cornhusker Economics

Agricultural commodities play a major role in Nebraska’s economy and are central to the life of many families in the state. Learning the main concepts of commodity marketing becomes essential for young Nebraskans considering careers in the agricultural industry or in farming. Therefore, in the last 10 years, the Department of Agricultural Economics has been expanding its curriculum in commodity marketing and merchandising, as has already been discussed in this space a few years ago (“Commodity Trading Room Comes Online at UNL,” 6/29/2016). Following the same ideas, we are now expanding our efforts to offer a program in commodity marketing …

Reassessment Of Chirita Umbrophila (Gesneriaceae) Based On Molecular And Morphological Evidence, Peng-Wei Li, James F. Smith, Debabrata Maity, Xi-Zuo Shi, Li-Hua Yang

Biology Faculty Publications and Presentations

Chirita umbrophila is a species endemic to Yunnan, China, and its exact systematic position remains a mystery since it was treated as a species with uncertain generic affiliation in the taxonomic revision of Chirita in 1985. In the present study, the phylogenetic relationships between C. umbrophila and its allied species were inferred using two nuclear ribosomal DNA regions (ETS and ITS) and three chloroplast regions (rpl16, rps16, and trnL-F). Additionally, the type locality of C. umbrophila was revisited and flowering specimens were collected and examined. Our phylogenetic analyses showed that Chirita umbrophila is imbedded in three …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard T. Melstrom, Mark A. Kaemingk, Nicholas W. Cole, John C. Whitehead, Christopher J. Chizinski, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Lepidopterans Of Economic Importance In Cameroon: A Systematic Review, José Ouaba, Timoléon Tchuinkam, Alida Waïmane, Henlay Juma Otieno Magara, Saliou Niassy, Félix Meutchieye

All Peer-Reviewed Publications

Lepidoptera represents one of the most abundant and diverse insect groups globally, with more than 178,159 species described in more than 4000 genera. This paper discusses the economic importance of these insects in Cameroon. The work was built on a comprehensive review of 60 relevant published articles from 1955 to 2021. Results show a great diversity of insects of economic importance belonging to the order Lepidoptera, of which 51 are known at the species level, eleven at the genus level, and many others not yet identified. Their economic importance is somehow conflicting, with a mix of harmful and beneficial species. …
