Assessing The Vulnerability Of At-Risk Amphibians To Regional Climate Change, Ross K. Hinderer

UM Graduate Student Research Conference (GradCon)

Title: Assessing the Vulnerability of At-Risk Amphibians to Regional Climate Change

Purpose: Climate change threatens the persistence of many species worldwide. However, the effects of climate change on a particular species or in a particular location vary based on many factors. Some amphibians may benefit from climate changes while others will not, so understanding the factors associated with higher risks of detrimental effects will allow decision-makers to focus on protecting particularly vulnerable species and populations. Unfortunately, many amphibian species are not well-studied so ecologists are missing key details about their habitat use or life cycle making typical methods …

Health, Land, And Heritage: Understanding Montana Suicide Through Culture, Emory C. Padgett

UM Graduate Student Research Conference (GradCon)

From Norman Maclean’s A River Runs Through It (1976) to the popular series Yellowstone, stories loom large in Montana, and their use goes beyond entertainment. Stories about the state are informative in understanding Montana culture and heritage because the myths, perspectives, and truths revealed through literature, art, and television are closely intertwined with the memories and values of its people; in an ongoing feedback, stories simultaneously originate in lived experience and actively shape experiences. Grounded in this cultural significance, I use media as an ethnographic lens through which to study social change in rural Montana, which has faced economic …

Predicting Huckleberry Habitat Using Species Distribution Models, Rebekah Brassfield

UM Graduate Student Research Conference (GradCon)

Geographic distribution of plants and animals is determined by a variety of overlapping habitat factors like soil type, elevation, or canopy cover. Understanding the complicated interactions between these factors and the impacts they have on species’ distributions is increasingly important in the face of changing environments and climates. Species distribution models (SDM) measure the importance of habitat variables in determining the spatial distribution of certain species. Because SDMs include a variety of habitat variables, they can be used to answer questions about habitat suitability, predict future distributions, and inform conservation efforts.

Philadelphia Story: Florida Gives William Bartram A Second Chance, Charlotte M. Porter

Florida Historical Quarterly

William Bartram’s book, Travels Through North & South Carolina, Georgia, East & West Florida . . ., published in 1791, presented the most “consistent aesthetic theory produced in America up to his day.“ 1 Two hundred years later, appreciation of this complex work requires an understanding of the author’s intellectual growth, for the Travels is both a volume of natural history and autobiography.

William Bartram's Travels In The Indian Nations, Charlotte M. Porter

Florida Historical Quarterly

In 1773, the famous American naturalist William Bartram returned to the southeast portion of what is now the United States. The region was a more dangerous place than he realized. American “patriots” from Georgia were making troublesome border raids into East Florida. Many of the English plantations were owned in absentia, and the lives of the resident managers were, as Bartram knew from personal experience, isolated. Indian groups far outnumbered white residents in the Floridas, and they were becoming increasingly hostile. With an estimated 4,500 warriors, the Lower Creeks seriously impeded any colonial presence in the East Florida interior. In …

Perishing Personhood, Alaina Mann

UNO Student Research and Creative Activity Fair

Many people think that art and science do not overlap, especially in an educational sense. As someone who is both a biology and studio art major, I wanted to explore this mentality. This past semester I dived into a project to prove just how much these subjects can work together to expand our understanding of how art can be used for research purposes in a medical setting. With support from my Life Drawing professor, I was able to create multiple drawings from life and from photographs centered around my grandmother's Alzheimer’s Disease during my frequent visits to her nursing home. …

Design And Development Of Software With A Graphical User Interface To Display And Convert Multiple Microscopic Histology Images, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Histological images are widely used to assess the microscopic anatomy of biological tissues. Recent advancements in image analysis allow the identification of structural features on histological sections that can help advance medical device development, brain and cancer research, drug discovery, vascular mechanobiology, and many other fields. Histological slide scanners create images in SVS and TIFF formats that were designed to archive image blocks and high-resolution textual information. Because these formats were primarily intended for storage, they are often not compatible with conventional image analysis software and require conversion before they can be used in research. We have developed a user-friendly …

The Influence Of Metal Contamination On The Fishery Of The Upper Clark Fork River, Montana, Usa, Taylor Gold Quiros

UM Graduate Student Research Conference (GradCon)

Historical mining and mineral processing have led to heavy metal contamination in the flood-plain of the Upper Clark Fork River of western Montana. This contamination has acted as a long-term stressor on the river and its inhabitants, the effects of which can be seen in changes in fish populations along the river's gradient of decreasing metal concentration with distance from the mining source. Understanding the relationships between stressors and ecological responses is essential for management and restoration goals pertaining to ecosystems negatively affected by anthropogenic activities. This study analyzed population distribution of salmonid species based on long-term monitoring and recent …

Soybean oil is one of the most consumed vegetable oils worldwide. Genetic improvement of its concentration in seeds has been historically pursued due to its direct association with its market value. Engineering attempts aiming to increase soybean seed oil presented different degrees of success that varied with the genetic design and the specific variety considered. Understanding the embryo’s responses to the genetic modifications introduced, is a critical step to successful approaches. In this work, the metabolic and transcriptional responses to AtWRI1 and AtDGAT1 expression in soybean seeds were evaluated. AtWRI1 is a master regulator of fatty acid (FA) biosynthesis, and …

Oral Susceptibility To Ivermectin Is Over Fifty Times Greater In A Wild Population Of Anopheles Albimanus Mosquitoes From Belize Than The Stecla Laboratory Reference Strain Of This Mosquito, Staci M. Dreyer, Kelsey J. Morin, Marla Magaña, Marie Pott, Donovan Leiva, Nicole L. Achee, John P. Grieco, Jefferson A. Vaughan

Biology Faculty Publications

Background

The STECLA strain of Anopheles albimanus has been in continuous colony for many years and is the reference strain on which genomic studies for the species are based. Recently, the STECLA strain was demonstrated to be much less susceptible to ivermectin ingested in a blood meal (4-day LC50 of 1468 ng/ml) than all other Anopheles species tested to-date (LC50 values range from 7 to 56 ng/ml). The ability of An. albimanus to survive ingestion of ivermectin at concentrations far beyond that typically found in the blood of ivermectin-treated people or livestock (i.e., 30–70 ng/ml) could invalidate the use of …

Alzheimer’s disease (AD) is a genetically complex disease for which nearly 40 loci have now been identified via genome-wide association studies (GWAS). We attempted to identify groups of rare variants (alternate allele frequency <0.01) associated with AD in a region-based, whole-genome sequencing (WGS) association study (rvGWAS) of two independent AD family datasets (NIMH/NIA; 2247 individuals; 605 families). Employing a sliding window approach across the genome, we identified several regions that achieved association p values <10⁻⁶, using the burden test or the SKAT statistic. The genomic region around the dystobrevin beta (DTNB) gene was identified with the burden and SKAT test and replicated in case/control samples from the ADSP study reaching genome-wide significance after meta-analysis (p_meta= 4.74 × 10⁻⁸ ). SKAT analysis also revealed region-based association around the Discs large homolog 2 (DLG2) …

Spin-Nernst Effect In Time-Reversal-Invariant Topological Superconductors, Taiki Matsushita, Jiei Ando, Yusuke Masaki, Takeshi Mizushima, Satoshi Fujimoto, Ilya Vekhter

Faculty Publications

We investigate the spin-Nernst effect in time-reversal-invariant topological superconductors, and show that it provides smoking-gun evidence for helical Cooper pairs. The spin-Nernst effect stems from asymmetric, in spin space, scattering of quasiparticles at nonmagnetic impurities, and generates a transverse spin current by the temperature gradient. Both the sign and the magnitude of the effect sensitively depend on the scattering phase shift at impurity sites. Therefore the spin-Nernst effect is uniquely suitable for identifying time-reversal-invariant topological superconducting orders.

Structure Of The Wilson Disease Copper Transporter Atp7b, Ryan M Bitter, Secheol Oh, Zengqin Deng, Suhaila Rahman, Richard K Hite, Peng Yuan

Open Access Publications

ATP7A and ATP7B, two homologous copper-transporting P1B-type ATPases, play crucial roles in cellular copper homeostasis, and mutations cause Menkes and Wilson diseases, respectively. ATP7A/B contains a P-type ATPase core consisting of a membrane transport domain and three cytoplasmic domains, the A, P, and N domains, and a unique amino terminus comprising six consecutive metal-binding domains. Here, we present a cryo-electron microscopy structure of frog ATP7B in a copper-free state. Interacting with both the A and P domains, the metal-binding domains are poised to exert copper-dependent regulation of ATP hydrolysis coupled to transmembrane copper transport. A ring of negatively charged residues …

Influence Of Particle Size And Zeta Potential In Treating Highly Coloured Old Landfill Leachate By Tin Tetrachloride And Rubber Seed, Siti Fatihah Ramli, Hamidi Abdul Aziz, Fatehah Mohd Omar, Mohd Suffian Yusoff, Herni Halim, Mohamad Anuar Kamaruddin, Kamar Shah Ariffin, Yung-Tse Hung

Civil and Environmental Engineering Faculty Publications

Old leachate normally has a low organic compound content, poor biodegradability and is hard to biologically treat. The efficacy of tetravalent metal salts as a coagulant and the application of a natural coagulant as a flocculant in landfill leachate treatment is still inconclusive. Hence, this study aimed to evaluate the potential application of tin tetrachloride (SnCl4 ) as the main coagulant and the rubber seed (Hevea brasiliensis) (RS) as the natural coagulant aid as the sole treatment in eradicating highly coloured and turbid stabilised landfill leachate present at one of the old local landfills in Malaysia. The standard jar test …

Molecular Biomarkers Of Adult Human And Dog Stress During Canine-Assisted Interventions: A Systematic Scoping Review, Jaci Gandenberger, Erin Flynn, Em Moratto, Ashley Wendt, Kevin Morris

Institute for Human-Animal Connection: Faculty Scholarship

Positive relationships, including those between humans and other animals, particularly dogs, may be a way to reduce stress in humans. However, research into this area is relatively new, and a comprehensive review of the impacts of these interactions on humans and dogs has not been conducted. A scoping review of the scientific literature was conducted to explore what is known about the impacts of canine-assisted interventions on molecular biomarkers (e.g., cortisol and oxytocin) and associated measures (e.g., heart rate and blood pressure) of human and canine stress. As reported across 27 identified studies, canine-assisted interventions have consistently been demonstrated to …

Many Avenues For Spatial Personality Research: A Response To Comments On Stuber Et Al. (2022), Erica F. Stuber, Ben S. Carlson, Brett R. Jesmer

Wildland Resources Faculty Publications

We are grateful for the thought-provoking and forward-looking commentaries (Dingemanse et al. 2022; Mabry 2022; Spiegel and Pinter-Wollman 2022; Vander Wal et al. 2022) in response to our meta-analysis of evidence for consistent among-individual differences in animals’ spatial behaviors (Stuber et al. 2022). A clear consensus is that our demonstration of the prevalence of repeatability across spatial behaviors, and taxa, is only the first step towards identifying the mechanisms and consequences of variation in spatial behavior. Here, we take the opportunity to emphasize key future directions pertaining to uncovering mechanisms, disentangling apparent personality from spatial constraints, and examining additional metrics …
