Assessing Stream Ecosystem Structure And Function In An Urban Canal And Logan River In Logan, Utah, Ellie Smith-Eskridge
All Graduate Theses and Dissertations
Humans have constructed canals to support agriculture, to mitigate flooding, and to discharge stormwater, especially in the Intermountain West. These canals are common in Cache Valley, where they receive flows from the Logan River during summer months. However, the ecological structure (e.g., water quality, freshwater invertebrates) and function (e.g., leaf decomposition) of these canals remains largely unknown. Studying ecosystem structure and function of these urban waterways is important because it can inform us of the health of these waterways.
My research had three objectives. First, I compared water chemistry, invertebrate assemblages, and leaf decomposition in an urban canal and the …

Targeted Mapping Of Oryza Sativa Chilling Tolerance Candidate Genes Using Multiple Stress-Relevant Quantitative Traits, Naoki Simon Shimoyama
Dissertations (1934 -)
Developing chilling tolerant accessions of domesticated Asian rice is a potential source of significant crop improvement to address the needs of a growing global population. The uniquely chilling sensitive nature of the tropically originating Oryza sativa make it the most important staple crop that could gain the maximum benefit from improved tolerance to low temperature stress. However, mechanisms underlying this complex trait are not fully understood. Oryza sativa has two major varietal groups with different levels of chilling tolerance, JAPONICA and INDICA, providing an ideal tool to investigate mechanistic differences in the chilling stress tolerance responses within this important crop …

A Brief Overview Of Triple A Syndrome, Jamaal Khan
Mako: NSU Undergraduate Student Journal
Triple A Syndrome, also known as AAA Syndrome, is a rare autosomal recessive disorder caused by any mutation in the AAAS gene on chromosome 12q13, whose main function is to code for the WD-repeat family regulatory protein, ALADIN. It typically occurs as a group of diseases that are characterized by alacrima, Addison's disease, and achalasia. Alacrima can be defined by a decrease in the amount of tears produced while achalasia is nerve damage in the esophagus that can cause difficulty swallowing. Lastly, Addison's disease is the insufficient production of cortisol and aldosterone produced by the adrenal cortex. There is no …

Freshwater Mussels Of Kansas: Register Of Taxa, Synonyms, And Assumed Misidentifications, Mark E. Eberle
Biological Sciences Faculty Publications
The literature on freshwater mussels (Mollusca: Margaritiferidae and Unionidae) of Kansas includes a collection of names of species and subspecies that makes it difficult for even experienced malacologists to decipher which taxa actually were collected. Compounding this problem is the absence of voucher specimens for some of the studies conducted in the state. This list was compiled to aid those who are conducting research and want to assess their results with reference to the earlier accounts. The alphabetical list of valid taxa, synonyms, and assumed misidentifications of freshwater mussels of Kansas is drawn from the literature and not an examination …

Methylene Blue Inhibits Cromakalim-Activated K+ Currents In Follicle-Enclosed Oocytes, Dmytro Isaev, Keun-Hang Susan Yang, Georg Petroianu, Dietrich Ernst Lorke, Murat Oz
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The effects of methylene blue (MB) on cromakalim-induced K+ currents were investigated in follicle-enclosed Xenopus oocytes. In concentrations ranging from 3–300 μM, MB inhibited K+ currents (IC50: 22.4 μM) activated by cromakalim, which activates KATP channels. MB inhibited cromakalim-activated K+ currents in a noncompetitive and voltage-independent manner. The respective EC50 and slope values for cromakalim-activation of K+ currents were 194 ± 21 µM and 0.91 for controls, and 206 ± 24 µM and 0.87 in the presence of 30 μM MB. The inhibition of cromakalim-induced K+ currents by MB was not …

The Effects Of Salinity And Acetaminophen On The Aquatic Snail Physa Acuta, Michelle Sackey-Ansah, Megan Mackey, Daniel Elias, Jason Doll, Alyssa Brookhart
Journal of the South Carolina Academy of Science
Pharmaceuticals are increasingly detected in water bodies, and their presence can negatively impact aquatic organisms. This effect can be amplified when combined with increasing salinity in freshwater ecosystems. Acetaminophen is a widely used analgesic that is commonly found in river, streams, and waters where it is discharged directly. Therefore, organisms present in these locations (e.g., insects, snails, amphibians, and fish) are likely to be affected by acetaminophen. In this study, we determined the effects of elevated salinity (0.68 g/L), acetaminophen (500 µg/L) and combined elevated salinity (0.68 g/L) and acetaminophen (500 µg/L), on the growth, reproduction, and movement of the …

Change And Stasis Of Distinct Sediment Microbiomes Across Port Everglades Inlet (Pei) And The Adjacent Coral Reefs, Lauren E. Krausfeldt, Jose V. Lopez, Catherine Bilodeau, Hyo Won Lee, Shelby L. Casali
Biology Faculty Articles
Deep water ports are human built coastal structures that by definition welcome ship traffic and disturbance. Evidence is accumulating that enhanced port activities such as dredging or deepening have negatively affected nearby natural habitats. Port Everglades Inlet (PEI) is a large active South Florida cargo port for over two million people and lies adjacent to coral reefs, dwindling mangroves, and recreational beaches. In this study, the microbial communities of PEI and adjacent reef sediments were characterized to serve as indicators for change due to dredging and assess anthropogenic influence on these sensitive ecosystems by sequencing the V4 region of 16S …

Insight From Biology Program Learning Outcomes: Implications For Teaching, Learning, And Assessment, Noelle Clark, Jeremy L. Hsu
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Learning goals and objectives are a key part of instruction, informing curricular design, assessment, and learning. These goals and objectives are also applied at the programmatic level, with program learning outcomes (PLOs) providing insight into the skills that undergraduate biology programs intend for their students to master. PLOs are mandated by all major higher education accreditation agencies and play integral roles in programmatic assessment. Despite their importance, however, there have not been any prior attempts to characterize PLOs across undergraduate biology programs in the United States. Our study reveals that many programs may not be using PLOs to communicate learning …

Karbala International Journal of Modern Science
One of the most anticipated challenges in the field of agriculture is to ensure high production levels while limiting the use of environmentally harmful synthetic chemicals. One of the most interesting strategies to overcome this challenge is the exploitation of the interactions between soil microorganisms and plants which result in stimulating plants’ natural activity. The interactions among mycorrhiza, growth-promoting microorganisms and plants play a crucial role in soil fertility, biocontrol and protection. The use of mixed microbial products can simulate interactions between fungi and bacteria, realising all the benefits that can be obtained from these associations in terms of quantity …

Selective And Differential Feeding On Marine Prokaryotes By Mucous Mesh Feeders, Carey P. Sweeney, Kelly R. Sutherland, Anne W. Thompson
Biology Faculty Publications and Presentations
Microbial mortality impacts the structure of food webs, carbon flow, and the interactions that create dynamic patterns of abundance across gradients in space and time in diverse ecosystems. In the oceans, estimates of microbial mortality by viruses, protists, and small zooplankton do not account fully for observations of loss, suggesting the existence of underappreciated mortality sources. We examined how ubiquitous mucous mesh feeders (i.e. gelatinous zooplankton) could contribute to microbial mortality in the open ocean. We coupled capture of live animals by blue-water diving to sequence-based approaches to measure the enrichment and selectivity of feeding by two coexisting mucous grazer …

Stamp Sand Along The Keweenaw Shoreline: Solid And Dissolved Copper & Effects On Biota, Gary Swain
Dissertations, Master's Theses and Master's Reports
Stamps sand refers to the regional colloquialism for the mine-tailing byproducts generated from copper (Cu) ore processing mills located in Michigan’s Keweenaw Peninsula. In the Keweenaw region, copper extracted from basalt ores resulted in a legacy of 100’s of millions of metric tonnes of stamp sand wastes, including 22.7 million metric tonnes at Gay, MI. Trace amounts of Cu persist in stamp sands and when leached have toxic enough concentrations to influence aquatic biota. To better understand stamp sands’ properties, we ran experiments and compiled data about the solid and dissolved phases of Cu. Solid phase concentration of Cu was …

Movement As Medicine: Dance/Movement Therapy For Individuals With Autism, Parkinson’S Disease, And Cancer, Alessia Zanobini
CMC Senior Theses
Dance/movement therapy (D/MT) is the psychotherapeutic use of expressive, creative movement to support holistic well-being. D/MT views the human being as a single body-mind unit and movement as a manifestation of life experiences. While typically practiced as a mental health intervention, D/MT can be adapted for a variety of populations. This thesis evaluates scientific data for the non-traditional use of D/MT for three conditions: autism, Parkinson’s disease, and cancer. For individuals on the autism spectrum, D/MT can strengthen attunement skills, provide creative communication outlets, and relieve harmful physical manifestations of autism. For individuals with Parkinson’s disease, D/MT can simultaneously ease …

The Role Of Herbal Medicines In Central American Indigenous Communities; Improving Accessibility To Type 2 Diabetes Mellitus Treatment, Sarai Ortega
CMC Senior Theses
Indigenous communities in Central America have used various plant medications to treat illnesses and diseases for centuries. Clinicians must consider improving traditional healthcare methods that are intrinsic to indigenous communities in order to increase access to effective treatments, particularly for diseases that these communities are more at risk for. This work aims to propose a method to identify whether traditional preparations of five plants (Anacardium occidentale L., Hamelia patens Jacq., Momordica charantia L, Neurolaena lobota L. R. Br. Ex Cass., and Tecoma stans L. juss. ex Kunth) can reduce blood glucose levels in rats with type two diabetes. Additionally, …

Potential Effects Of Road Proximity On Zooplankton Communities And Water Quality In Lakes In The Northwest Territories, Marie N. Hannan
Theses and Dissertations (Comprehensive)
Studies conducted along Canada’s Dempster Highway in the Northwest Territories have shown that road dust can affect water quality in roadside lakes, leading to higher calcium, conductivity, and pH levels. These water quality changes have the potential to affect important members of the lower aquatic food web, such as zooplankton.
For my thesis research, I had two main objectives: 1) To determine if changes in water chemistry caused by deposition of road dust affects zooplankton communities; and 2) To examine if the type of roadside vegetation influences the effects of road dust on aquatic habitats. To achieve these objectives, I …

The Effect Of Alkalinity On Lampricide Effectiveness And Gill Physiology In Invasive Sea Lamprey (Petromyzon Marinus), Alexandre J. Walsh
Theses and Dissertations (Comprehensive)
The pesticides, 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide are used to control populations of invasive sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes of North America. Added to streams infested with larval sea lamprey, the effectiveness of these pesticides, commonly called lampricides, are strongly influenced by water pH, with greater toxicity for both TFM and niclosamide in lower pH than higher pH water. However, the TFM and niclosamide sensitivity of sea lamprey are also greater in poorly buffered, low alkalinity water than in high alkalinity water but it is unclear why. One goal of my thesis was to propose …

Biology Faculty Publications and Presentations
The photochemical evolution of polycyclic aromatic hydrocarbons (PAHs), an abundant form of meteoritic organic carbon, is of great interest to early Earth and Mars origin-of-life studies and current organic molecule detection efforts on Mars. Fe-rich clay environments were abundant on early Earth and Mars, and may have played a role in prebiotic chemistry, catalyzing the breakdown of PAHs and freeing up carbon for subsequent chemical complexification. Current Mars is abundant in clay-rich environments, which are most promising for harboring organic molecules and have comprised the main studied features by the Curiosity rover in search of them. In this work we …

Montclair State University
A Bioinformatics Approach For Evaluating Evolutionary Convergence Of Gene Family Size In Hematophagous Insects, Mbemba Ceesay
Theses, Dissertations and Culminating Projects
The act of blood-feeding can be nutritionally rewarding for blood-feeding arthropods. However, blood digestion can release pro-oxidant molecules such as heme and iron at potentially harmful levels. If left uncontrolled, this heme/iron can cause oxidative damage and eventually cell death. This has led to the evolution of various adaptations that protect blood-feeding arthropods against iron- and heme-associated damage. Here I postulate that the signature of this adaptation can be observed in patterns of gene family size. To test this hypothesis, I explore convergent evolutionary expansions and contractions of gene families in distinct lineages of hematophagous insects. Specifically, I compare the …
