Size Selective Parasitism Of Rainbow Trout (Oncorhynchus Mykiss) By Chestnut Lampreys (Ichthyomyzon Castaneus) In An Artificial Setting, Jeremiah M. Salinger, Ronald L. Johnson May 2020

Size Selective Parasitism Of Rainbow Trout (Oncorhynchus Mykiss) By Chestnut Lampreys (Ichthyomyzon Castaneus) In An Artificial Setting, Jeremiah M. Salinger, Ronald L. Johnson

Southeastern Fishes Council Proceedings

Paradigms of optimal resource utilization by animals, both classical and more recent, were not originally developed in the context of parasitism. Though this oversight has slowly been reversed, little attention has been paid to optimal resource utilization by parasitic fishes, such as lampreys. Multiple explanations for host size selection by parasitic lampreys may be plausible, but results from previous studies have been inconsistent. We studied host size selection by Chestnut Lampreys (Ichthyomyzon castaneus) parasitizing Rainbow Trout (Oncorhynchus mykiss) in fish hatchery raceways in north central Arkansas during the late winter and early spring of 2013. Parasitized Rainbow Trout were significantly ...


Movement Of Translocated Adult Sicklefin Redhorse (Moxostoma Sp.) In The Oconaluftee River, North Carolina: Implications For Species Restoration, Jessica L. Davis, David P. Gillette, C. Reed Rossell Jr., Michael J. Lavoie May 2020

Movement Of Translocated Adult Sicklefin Redhorse (Moxostoma Sp.) In The Oconaluftee River, North Carolina: Implications For Species Restoration, Jessica L. Davis, David P. Gillette, C. Reed Rossell Jr., Michael J. Lavoie

Southeastern Fishes Council Proceedings

The Sicklefin Redhorse is a rare, undescribed species of Moxostoma, endemic to the Hiwassee and Little Tennessee River basins of western North Carolina and northern Georgia, where it has been eliminated from much of its native range. It is listed as endangered in Georgia and threatened in North Carolina. Although it has not been granted federal protected status, this species is the subject of a Candidate Conservation Agreement between federal, state, tribal, and private stakeholders, of which one objective calls for the re-establishment of Sicklefin Redhorse populations throughout its historical range. The objective of our study was to evaluate suitability ...


Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell May 2020

Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell

Southeastern Fishes Council Proceedings

The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the ...


Use Of Dead Mussel Shells By Madtom Catfishes In The Green River, Jacob F. Brumley, Philip W. Lienesch May 2020

Use Of Dead Mussel Shells By Madtom Catfishes In The Green River, Jacob F. Brumley, Philip W. Lienesch

Southeastern Fishes Council Proceedings

The Green River in Kentucky has high fish and macroinvertebrate diversity. As both fish and macroinvertebrates have evolved together in this system, relationships have developed between species. One type of relationship that has been observed is between madtom catfishes (Noturus spp.) and mussels in the Green River, where madtoms use dead mussel shells as cover when not actively foraging. In the fall of 2016 and 2017, surveys were conducted to determine if madtom catfishes use dead mussel shells more than rocks of similar size. We predicted that madtoms would select mussel shells as cover more frequently than rocks due to ...


Molecular Characterization Of A Gene Encoding Insulin-Like Peptide 5 (Ilp5) In Drosophila Virilis, Nikolas R. Likourentzos, Jae H. Park May 2020

Molecular Characterization Of A Gene Encoding Insulin-Like Peptide 5 (Ilp5) In Drosophila Virilis, Nikolas R. Likourentzos, Jae H. Park

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

The study of the insulin-like peptides of Drosophila can provide insight of their similarities to mammalian insulin and their potential usage in treating human insulin-related diseases. In this study, we isolated and characterized cDNA encoding insulin-like peptide (ILP) 5 in D. virilis by using RNA purification, reverse transcription, and RACE protocols. Subsequently, various bioinformatic softwares were employed to predict peptide structure. The ILP5 gene (587 base pairs) codes for 121 amino acids that make up prepro-ILP5. After maturation, functional ILP5 is a peptide of two 25 amino acid chains, A- and B-chain, connected by two disulfide bonds. Sequencing genomic DNA ...


The Current Neuroscientific Understanding Of Alzheimer's Disease, Rachel A. Brandes May 2020

The Current Neuroscientific Understanding Of Alzheimer's Disease, Rachel A. Brandes

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Alzheimer’s disease is a degenerative neurological illness characterized by the deterioration of brain regions implicated in memory and cognitive function. While researchers have yet to find a cure or effective treatment, they have gained a better understanding of its pathology and development. Through years of neuroscience research, scientists have discovered much of what happens in the brain during Alzheimer’s disease onset and how this causes its symptoms; many hypotheses regarding this aspect of the illness involve temporal lobe atrophy, neurofibrillary tangles, and amyloid plaques. Although Alzheimer’s disease affects millions of people every day, it seems that most ...

Outperformed: Exploration And Comparison Of The Tongue-And-Cheek Tragedies Of Women-Animal Relationships In Selected Short Stories By Samanta Schweblin And In Apichatpong Weerasethakul’S Film, Uncle Boonmee Who Can Recall His Past Lives, Sawnie Smith Apr 2020

Outperformed: Exploration And Comparison Of The Tongue-And-Cheek Tragedies Of Women-Animal Relationships In Selected Short Stories By Samanta Schweblin And In Apichatpong Weerasethakul’S Film, Uncle Boonmee Who Can Recall His Past Lives, Sawnie Smith

Vernacular: New Connections in Language, Literature, & Culture

The unsettling short stories that comprise Samanta Schweblin’s 2008 collection Pájaros en la boca are textured and populated by the flesh of not only humans, but also the skins of species that belong to a wider zoological and mythical scope. Those creatures in Schweblin’s literary output who possess scales, feathers, and wings find themselves variously rubbing up against, crushed under, and orally engulfed by human dermis. This essay seeks to explore the charge of gender politics that courses through interactions between human women and (demi-) animals in two short stories from this collection: “El hombre sirena” and “Olingiris ...


Labor Use And Labor Challenges Faced By Small Fruit And Vegetable Farms: The Case Of Tennessee, Justin L. Cross Jan 2020

Labor Use And Labor Challenges Faced By Small Fruit And Vegetable Farms: The Case Of Tennessee, Justin L. Cross

Haslam Scholars Projects

United States (U.S.) fruit and vegetable farms depend heavily on labor for the production of the crops they grow and sell. In recent years, it has become increasingly difficult for farms to obtain the labor they need to produce their crops. Therefore, labor management strategies have become critical in determining the profitability and long-term sustainability of farms specializing in the production of fruits and vegetables. These strategies are even more significant for smaller farms that face resource constraints that inhibit their use of alternative labor sources (e.g., migrant workers) or their ability to reduce their reliance on labor ...

Developing A Hands-On Food Science Curriculum With Bilingual, Elementary-Aged, Hispanic Heritage Students, Jaime Leia Ragos May 2019

Developing A Hands-On Food Science Curriculum With Bilingual, Elementary-Aged, Hispanic Heritage Students, Jaime Leia Ragos

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

In the United States alone there are over 48 million cases of foodborne illness, with most of these cases deriving from food cooked in the home (Young 2016). Many themes have been assessed such as confidence, knowledge, habits, taste in food preferences, and societal/social influences (Young 2016). However, when food safety curricula are targeted toward younger populations, including young adults and children, attitudes and behavior change (Mullan 2018 and Young 2016). As there is a lack in home economics education in today’s current curriculum, students and their families may not know food safety behaviors (Finch 2005; Young 2016 ...

Applications Of Optimization Modeling In Multi-Disciplinary Engineering Research, Anton F. Astner, Ekramul Haque Ehite, Yang Li, Colin Sasthav

Biosystems Engineering and Soil Science Publications and Other Works

Optimization modeling is the process of selection of the best solution to a design problem using predetermined constraints from a set of prospective solutions. Increased computing power has made optimization solvers readily available for business/research needs. For example, Microsoft Excel has a simple, but robust solver. Such solvers can model linear, nonlinear, and integer programming problems that are limited in size. This study shows the use of the optimization model solvers in various research contexts.


Exploring The Structure-Activity Relationship Of Various Seh Inhibitors In Promoting Brown Adipogenesis, Sue Lim Choi Apr 2019

Exploring The Structure-Activity Relationship Of Various Seh Inhibitors In Promoting Brown Adipogenesis, Sue Lim Choi

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Background: Brown adipose tissue has emerged as a novel target for obesity prevention and treatment due to its responsibility for heat production. Soluble epoxide hydrolase (sEH) is a cytosolic enzyme that degrades epoxy fatty acids (EpFAs) (lipid signaling molecules) into inactive diols. Potent sEH inhibitors (sEHIs) are beneficial for many chronic diseases as they stabilize endogenous EpFAs by blocking the degradation. Our preliminary results have shown that trans-4- [4-(3-adamantan-1-yl-ureido)-cyclohexyloxy]-benzoic acid (t-AUCB), a potent sEH inhibitor, dose-dependently promotes brown adipogenesis.

Objectives: The objective of this study is to investigate the structure and activity relationship of various sEHIs with ...
