Insights Into Insular Isolation Of The Bull Shark, Carcharhinus Leucas (Müller And Henle, 1839), In Fijian Waters, Kerstin B J Glaus, Sharon A. Appleyard, Brian Stockwell, Juerg M. Brunnschweiler, Mahmood S. Shivji, Eric Clua, Amandine D. Marie, Ciro Rico

Biology Faculty Articles

The bull shark (Carcharhinus leucas) is a large, mobile, circumglobally distributed high trophic level predator that inhabits a variety of remote islands and continental coastal habitats, including freshwater environments. Here, we hypothesize that the barriers to dispersal created by large oceanic expanses and deep-water trenches result in a heterogeneous distribution of the neutral genetic diversity between island bull shark populations compared to populations sampled in continental locations connected through continuous coastlines of continental shelves. We analyzed 1,494 high-quality neutral single nucleotide polymorphism (SNP) markers in 215 individual bull sharks from widespread locations across the Indian and Pacific Oceans …

Michigan Tech Publications, Part 1

MicroRNAs are important regulators in plant developmental processes and stress responses. In this study, we generated a series of maize STTM166 transgenic plants. Knock-down of miR166 resulted in various morphological changes, including rolled leaves, enhanced abiotic stress resistance, inferior yield-related traits, vascular pattern and epidermis structures, tassel architecture, as well as abscisic acid (ABA) level elevation and indole acetic acid (IAA) level reduction in maize. To profile miR166 regulated genes, we performed RNA-seq and qRT-PCR analysis. A total of 178 differentially expressed genes (DEGs) were identified, including 118 up-regulated and 60 down-regulated genes. These DEGs were strongly enriched in cell …


Assessing Moringa Oleifera Plants As Exposure Pathways For Heavy Metals In Highly Contaminated Areas, Marissa Louise Mayfield* Dec 2020

Assessing Moringa Oleifera Plants As Exposure Pathways For Heavy Metals In Highly Contaminated Areas, Marissa Louise Mayfield*

Biology Theses

This study examined the uptake of heavy metals by Moringa oleifera trees in both field and laboratory settings. The main goal of this study was to determine whether using Moringa, grown in heavily contaminated areas, as food or herbal supplements increases the risk of heavy metal exposure. The field component of this study was carried out in the Southern part of Kabwe, Zambia where a lead-zinc mine has left a legacy of severe environmental pollution in the neighboring areas. Moringa trees have several medicinal properties which is one of the reasons they were first introduced to the area. The trees …

Prevalence Of Snake Fungal Disease Caused By Ophidiomyces Ophiodiicola In East Texas, Alan Lizarraga Dec 2020

Prevalence Of Snake Fungal Disease Caused By Ophidiomyces Ophiodiicola In East Texas, Alan Lizarraga

Biology Theses

Fungal pathogens and resultant disease are credited with the decline of many species across all branches of the tree of life. Fungal diseases such as Snake Fungal Disease (SFD), primarily caused by the fungus Ophidiomyces ophiodiicola (Oo), have been strongly associated with the cause of the decrease/disappearance of many snake populations in North America. To date SFD in the wild has been described as far southwest as central Louisiana. Due to similar conditions and the proximity of East Texas to central Louisiana, a survey of local snake populations provided crucial information about the spread and presence of this emerging pathogen. …


Comparison Of Threatened Neosho Madtom Densities Between Riverscapes Differing In Anthropogenic Stressors, With A Particular Focus On Recovery From Mining-Derived Metal Pollution, Kali Boroughs Dec 2020

Comparison Of Threatened Neosho Madtom Densities Between Riverscapes Differing In Anthropogenic Stressors, With A Particular Focus On Recovery From Mining-Derived Metal Pollution, Kali Boroughs

Electronic Theses & Dissertations

Water pollution imperils the Neosho Madtom (Noturus placidus), which is threatened in Kansas and federally. Within Kansas madtom densities were historically lower in the Spring River compared to the Cottonwood and Neosho Rivers, especially within the Spring River below tributary inputs that delivered cadmium, lead, and zinc pollution from the Tri-State Mining District. Studies suggest that madtoms are less numerous in waters containing elevated metal concentrations because of direct toxicity and lower benthic macroinvertebrate availability, which is also depressed by elevated metal concentrations. However, long-term reductions in metal concentrations in the Spring River have occurred, but to date …


Functional Investigations Of Proteins And Enzymatic Toxins From Full-Length-Enriched Cdna Of Timber Rattlesnake (Crotalus Horridus), Joshua Osula Dec 2020

Functional Investigations Of Proteins And Enzymatic Toxins From Full-Length-Enriched Cdna Of Timber Rattlesnake (Crotalus Horridus), Joshua Osula

Theses

Snake Venom is a highly modified form of saliva, contains hundreds of zootoxins, necrotoxins, cytotoxins, neurotoxins, and mytotoxins, all of which are primarily made up of mostly proteins, polypeptides, and other components such as enzymes, lipids, and carbohydrates. Although snake venom is known for its harmful effects, it has also had a positive impact in scientific discovery and medicine. Some toxins from snakes function to inhibit pain, and this means they can be very effective analgesics. For instance, crotalphine is considered a 14-amino-acid-peptide that has a disulfide bond and shows analgesic properties through TRPA1 desensitization. This …

Harris, Gang Li, Le Zhao, Nicole M. Foley, Melody E. Roelke-Parker, Stephen James O'Brien, Leslie A. Lyons, Wesley C. Warren, William J. Murphy

Biology Faculty Articles

In addition to including one of the most popular companion animals, species from the cat family Felidae serve as a powerful system for genetic analysis of inherited and infectious disease, as well as for the study of phenotypic evolution and speciation. Previous diploid-based genome assemblies for the domestic cat have served as the primary reference for genomic studies within the cat family. However, these versions suffered from poor resolution of complex and highly repetitive regions, with substantial amounts of unplaced sequence that is polymorphic or copy number variable. We sequenced the genome of a female F1 Bengal hybrid cat, the …


Exposing Lettuce Plants To Cyanobacteria In A Closed Hydroponics System To Reduce Cyanobacterial Growth And Production, Emily Eberly Dec 2020

Exposing Lettuce Plants To Cyanobacteria In A Closed Hydroponics System To Reduce Cyanobacterial Growth And Production, Emily Eberly

Honors Projects

Sandusky Bay is largely populated by cyanobacterial algal blooms, mainly formed by Planktothrix. Fertilizers containing nitrogen and phosphorus run from agricultural lands into the bay, building up excess nutrients forming eutrophic waters. The Planktothrix feed off these nutrients and grow into algal blooms. To determine a potential solution to the growth of these blooms, I implemented a hydroponics system involving Lactuca Sativa for analysis of Planktothrix growth and productivity. Four different nutrient conditions were added to a Planktothrix-only solution and a solution growing Planktothrix with the lettuce in the hydroponics system. The four conditions consisted of no nutrient …

Taxonomic Review Of South American Butter Frogs: Phylogeny, Geographic Patterns, And Species Delimitation In The Leptodactylus Latrans Species Group (Anura: Leptodactylidae), Felipe De M. Magalhães, Mariana L. Lyra, Thiago R. De Carvalho, Diego Baldo, Francisco Brusquetti, Pamela Burella, Guarino R. Colli, Marcelo C. Gehara, Rafael O. De Sá, Et Al.

Biology Faculty Publications

The Leptodactylus latrans species group currently comprises eight medium- to large-sized frog species with a convoluted taxonomic history, particularly related to the specific limits of the L. latrans complex, and the species pair Leptodactylus chaquensis–Leptodactylus macrosternum. Their homogeneous external morphology and continental geographic distribution in South America have posed severe limitations to a comprehensive review, such that taxonomic consensus and species limits remain uncertain. This is further worsened by the presence of chromatic polymorphism among coexisting species that can hardly be distinguished by external morphology. Based on a large-scale geographic sampling including multilocus DNA analyses, and acoustic …


Altered Toxin Binding Or Access To The Binding Site, What Changes In The Tetrodotoxin Resistant Sodium Channels Of Garter Snakes?, Kenyon Mitchell Dec 2020

Altered Toxin Binding Or Access To The Binding Site, What Changes In The Tetrodotoxin Resistant Sodium Channels Of Garter Snakes?, Kenyon Mitchell

Fall Student Research Symposium 2020

Voltage-gated sodium ion channels are required for the generation and propagation of action potentials in vertebrate nerve and muscle cells. The neurotoxin tetrodotoxin (TTX) binds in the channel pore and blocks sodium channel function. Some populations of garter snakes (Thamnophis sirtalis) have evolved resistance to TTX in part due to amino acid substitutions in the pore of the voltage-gated sodium channel expressed in skeletal muscle fibers (tsNaV1.4). We have previously demonstrated that the four amino acid substitutions in tsNaV1.4 from snake populations in California reduce TTX binding. These four amino acid substitutions are at or near an amino acid position …

The Effects Of Estrogen And Arousal On Latent Inhibition, Michael Herron Dec 2020

The Effects Of Estrogen And Arousal On Latent Inhibition, Michael Herron

Fall Student Research Symposium 2020

The behaviors of humans and animals are dependent on neurotransmitters and hormones that affect attention, alertness, and associative learning. These include the hormone estrogen (which plays an interesting role in cognition and attentional processes) and the neurotransmitter orexin (involved in wakefulness, arousal and goal-directed behaviors). Here we evaluated the roles of orexin receptors and estrogen in Latent Inhibition (LI), a measure of attention and associative learning. Latent inhibition is a behavioral phenomenon in which an organism's ability to associate new meaning to a familiar previously inconsequential (pre-exposed) stimulus is reduced when compared to associating meaning to a novel stimulus (non …

Examining Ages Of Birds That Have Fatally Collided With Windows At Usu's C&Ss Building, Brigham City, Ut, Taylor Kenyon

Fall Student Research Symposium 2020

Around 97.6-975.6 million birds fatally collide with windows each year in North America. Bird age could be a contributor to the collisions. The central focus of our research project is to determine if there is a statistically significant relationship between the age of an individual bird and the likelihood of a fatal collision with a human-made window. The data collection method that will be used for this project is a hybrid of primary and secondary research. Personally collected data regarding window collisions, will be obtained from daily surveys of the Classroom and Student Services (CSS) Building at the Utah State …

Analyzing Fatal Bird-Window Collisions Occurring On Usu's C&Ss Building, Brigham City, Utah, Jacob Larkin

Fall Student Research Symposium 2020

Fatal bird window collisions are often overlooked as minimally damaging to bird populations or viewed as inevitable collateral damage of human habitat expansion. In reality, these unnecessary collisions are truly monumental in number, and prove to be a serious threat to bird populations, especially endangered bird species. In the United States alone it is estimated that between 365 - 988 million birds fatally collide with man-made windows annually. We are focusing our study on fatal bird-window collisions occurring on the Classroom and Student Services Building (C&SS building) at the USU campus in Brigham City, UT 84302. We have selected this …

Recently, there's been a surge of research about child-robot interactions as robots are being used in classrooms and homes in increasing numbers. Many of these studies are conducted in a laboratory-like setting followed by a survey. This project is unique in that we primarily rely on observational data in classrooms where students are using robots to learn math and Computational Thinking skills including Spatial Reasoning, Algorithmic Thinking, Debugging, and Decomposition. While the main purpose of the larger project is to develop curriculum and assessments for these skills, the structure of the FSRS project proposal allows us to also analyze these …


Bird-Window Collision Mitigation At Usu's C&Ss Building, Brigham City, Utah, Hunter Martin Dec 2020

Bird-Window Collision Mitigation At Usu's C&Ss Building, Brigham City, Utah, Hunter Martin

Fall Student Research Symposium 2020

Bird-window collisions are often not thought about as if they are a major problem to bird populations worldwide. This is not the case as bird populations are threatened by these collisions. In the United States alone it is estimated that 97.6 - 975.6 million birds fatally collide with human-made windows annually, and another 16 to 42 million collide in Canada per year. Our focus is to investigate a possible window collision problem and explore different mitigation efforts to prevent these collisions at the USU-Brigham City campus (Brigham City, Utah, 84302). We hope to determine how many fatal bird-window collisions are …


The Importance Of Experiment Replication In Understanding Distribution Of 'Alalā Seed Retention Time, Camilla Moses Dec 2020

The Importance Of Experiment Replication In Understanding Distribution Of 'Alalā Seed Retention Time, Camilla Moses

Fall Student Research Symposium 2020

Hawaiian forests have suffered damages from climate change, introduced plants, and introduced animals that trample or graze on the native vegetation. The 'Alalā, a native Hawaiian bird that is being reintroduced from captivity, is a disperser of native plants and can facilitate the restoration of native vegetation in Hawaiian forests. If the seed retention time and the flight paths of the 'Alalā are known, we can estimate the distribution of the seeds they disperse and see the effect the species has on forest restoration. In this study, the seed retention time of the 'Alalā is predicted from body mass using …


Identification And Characterization Of Pd-L1 In Bovine Placentas, Andre Nguyen Dec 2020

Identification And Characterization Of Pd-L1 In Bovine Placentas, Andre Nguyen

Fall Student Research Symposium 2020

Successful bovine pregnancy requires that the maternal immune system modulate T lymphocytes. Program death-ligand 1 (PD-L1) is an inhibitory protein that is associated with immune tolerance and modulation of T cells. Previous studies have linked PD-L1 to suppressing T cell activity and modulating cytokine production, therefore, inducing maternal tolerance and acceptance of the fetus. PD-L1 may be a possible mechanism involved in establishing successful bovine pregnancies. To this day, no evidence of PD-L1 RNA or protein was found in bovine placentas. We hypothesize that PD-L1 is present in the bovine placenta and its expression differs between trimesters. To analyze the …

An Examination Of Barriers And Determinates Impacting The Healthcare Of Kalamazoo County's Transgender And Non-Binary Young Adult Population, Tyler Signorella

Honors Theses

Historically non-binary and transgender individuals have faced and continue to face a unique set of obstacles and challenges in seeking and receiving general healthcare. Within the US this is well documented on a national level. In this exploratory study we will seek to understand the experience of young adults in Kalamazoo County comparing their perspectives to the already established pool of information. This will be accomplished through surveying emergent adults identifying as either transgender or gender non-binary within Kalamazoo County and then synthesizing this data into an analyzable collective format.
