This article goes in-depth on what is already known about the biological problems of being in space and potential solutions to remedy the complications.

Comparing Allelochemicals Of ​English Ivy And Native Georgia Plants​, Rebecca Senft

Symposium of Student Scholars

English Ivy (Hedera helix L.) is a common invasive plant causing biodiversity losses across the southeast and parts of the northwestern US. The mechanisms by which Ivy invades native ecosystems are not well understood but may include allelopathy, a process through which one species produces biochemicals that disrupt competitors. These biochemicals are often produced and exuded by roots into soil, making them difficult to isolate. This study used a soil-less hydroponic system and gas-chromatography mass spectroscopy to examine differences in the chemicals produced by roots of native Georgia plants and English Ivy. Our results suggest there are differences in the …

A Gud Toolbox: Implementation Of Giving-Up Densities With Mammals, Brandon Preston, Jordan Tandy, Kundil Patel, Karissa Coffield

Scholars Week

Giving-up densities are the density of food remaining within an artificial foraging patch over a specified time and are an indicator of how an organism perceives its environment. The GUD method is particularly useful to study the foraging behavior of an organism relative to predation risk and interactions with other environmental variables (e.g., cover, conspecifics, and food quantity and quality) to address larger ecological and evolutionary questions. The GUD methodology is commonly used with the mammalian taxonomic group due to their general size, detectability, and abundance in comparison to other taxa. However, development of protocols that maximize the potential for …

Mapping Fetch And Diel Movements Of Silver Carp Hypophthalmichthys Molitrix Within Kentucky Lake And Lake Barkley With Gis, Levi Umland

Scholars Week

Title: Mapping Silver Carp movements, relative exposure, and fetch within inland reservoirs using Geographic Information Systems.

Author: Levi G Umland

Invasive species across our country have continued to threaten our native species, compete for habitat via interspecific competition, and have caused economic impacts. Silver Carp (Hypophthalmichthys molitrix), commonly referred to as Asian Carp, have remained in the invasive species spotlight throughout the southern and mid-western states as they have continued to spread. Silver Carp have successfully spread through our rivers and reservoirs, but little is known about Silver Carp movement rates/behavior within reservoirs due to their lower abundance within …

Genetic Effect Of Long-Term Angling Pressure On Bluegill Populations In Small Impoundments In Kansas, Morganne Borsh

Three Minute Thesis (3MT®) at UNI

Bluegill (Lepomis macrochirus) is a versatile sport fish popularly fished across Kansas. Over the last decade, Bluegill catch rates have decreased, likely from high angler harvest rates of larger individuals. Large males that exhibit parental care have high growth rates and aggressively defend nests, making them vulnerable to angling. Males that display cuckoldry behavior reach maturity sooner, exhibit slower growth rates, and are generally smaller. The goal of this study is to determine if fisheries-induced evolution resulting from long-term harvest has led to a decline in the growth rate of Bluegill. A total of 100 individuals were sampled from ten …

24andmore: Using Genomics To Improve Walleye (Sander Vitreus) Stocking In Iowa, Rachel Mcdonnell

Three Minute Thesis (3MT®) at UNI

Walleye, Sander vitreus, is one of the top gamefish in Iowa. Due to poor natural reproduction in many Iowa waterbodies, populations are managed with stocking. There are two strains of walleye used to stock Iowa’s inland waters: a river strain derived from the Mississippi River near Genoa, WI and a lake strain derived from Spirit Lake, IA. Each strain may have unique characteristics relative to their environment that could affect the fitness and success of fish stocked. The goal of this study is to understand the genetic diversity within and between each strain to offer stocking guidance to the Iowa …

Medical Illustration As A Tool For Health Literacy, Courtney Anne Wombles

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Health literacy is most commonly described as the ability of an individual to obtain, comprehend, and utilize information related to their health. Including the ability to read, write, speak, and display numeracy in medical situations, rates of health literacy impact the ability of an individual to navigate the healthcare system and make informed decisions. As reported by the National Assessment of Adult Literacy, only 12% of individuals have the proficiency to understand and manage their health. This research identifies problems existing in health literacy and doctor-patient communication, with an emphasis on consumer health information. It explores resources used for science …

Bacteriophages Infecting Enterobacter Cloacae To Reduce Bloater Damage In Fermented Cucumbers

Symposium of Student Scholars

Fermented cucumbers are one of the most important fermented vegetables consumed worldwide. During cucumber fermentations, certain undesirable changes may occur. One of such changes is known as bloater defect (hollow cavities in fermented cucumbers), which is primarily caused by gas-producing bacteria including Enterobacter cloacae. Bloater defect lowers product quality and leads to significant economic loss to the pickle industry, and effective preventative methods are needed. Bacteriophages (phages) are highly host-specific bacterial killers. Use of phages to control unwanted bacteria in foods is a promising approach because phages do not change food properties. This research was to isolate, characterize, and …

Food Deserts: Hungry For Answers, Lawren Cumberbatch

Symposium of Student Scholars

In 2010, the United States Department of Agriculture (USDA) reported that 23.5 million people in the United States live in food deserts. As defined by the USDA, a “food desert” is a neighborhood that lacks healthy food sources. This can be measured by distance to a store, number of stores in an area, individual-level resources such as family income or vehicle availability, and neighborhood-level resources such as availability of public transportation. Past research provides evidence that food deserts are especially likely to occur in communities heavily populated by minorities. As a Black Indian pre-med student aiming to join the world …

Determining Malignancy: Can Mammogram Results Help Predict The Diagnosis Of Breast Tumors?, Taylor Behrens

Symposium of Student Scholars

Even with advancements in treatment and preventative care, breast cancer remains an epidemic claiming more than 40,000 American male and female lives each year. The mammogram dataset that I am analyzing was initially complied in the early 1990s by a team from the University of Wisconsin - Madison. Past research diagnoses breast cancer from fine-needle aspirates. My research focuses on predicting whether we can determine breast cancer diagnoses without the use of invasive procedures and, in particular, whether we can predict breast cancer based on mammogram data. Do measures of gray-scale texture, radius, concavity, perimeter, compactness, area, and smoothness of …

Initial Assessment Of Potential Relationships Between Plant Communities And The Soil Microbiome In Closed Forest And Longleaf Pine Restoration Sites., Sean Davis, Ian Kennedy

Symposium of Student Scholars

Longleaf pine is an endangered ecosystem characterized by high levels of biodiversity.

Our study took place in the Sheffield Wildlife Management Area located in the Piedmont ecoregion of Georgia in Paulding County. Fifty plots of 10 x 30 m² were setup on south or north facing slopes, some in covered forest, and some in an area actively being restored for the longleaf pine. All trees above 1.37 m were identified and had their diameter measured, and species diversity, relative density, dominance, and frequency were determined. Herbaceous plant cover percentages were recorded in select plots. Soil samples were also collected …

Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath

Symposium of Student Scholars

Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …

Optimization Of Dna Extraction From Difficult Sandy-Loam Soils, Anka Colo

Undergraduate Student Research Internships Conference

Ginseng is a high value perennial crop grown for its roots. A four-year cultivation cycle is required to obtain marketable ginseng roots, during which a condition called ginseng replant disease (GRD) develops. GRD is characterized by a severe root rot disease, and prevents the growth of newly planted ginseng in a former ginseng garden1. Microbiome analysis of ginseng garden soil will help our understanding of the formation of GRD and its severity. However, extracting DNA from the sandy-loam soils required for ginseng cultivation is difficult. Commercial kits are either too expensive or not applicable to the large volumes of soil …
