Developing Activities On Uncharismatic Animals Found At Omaha's Henry Doorly Zoo And Aquarium, Justin Hultquist

Honors Program: Senior Projects (Public)

The Education Department at Omaha’s Henry Doorly Zoo and Aquarium has a number of educational activities based on charismatic species found there. I wished to develop activities the department may use for less charismatic or misunderstood species at the zoo. I began by surveying the exhibits at the zoo and taking note of what species or groups didn’t receive as much visitor engagement, or what comments were made on species that were incorrect. I then began to brainstorm and narrow down potential species that I could develop an educational activity around. As I began to develop and create activities, a …

Comparison Of Transcervical Insemination Versus Surgical Insemination Methods In Dogs At A Veterinary Clinic In Lincoln, Nebraska, Lauren Ahlers

Honors Program: Senior Projects (Public)

Artificial insemination paved the way for many advancements in reproductive technology. Two common artificial insemination methods recommended for use with frozen semen are transcervical insemination and surgical insemination. To better understand the conception rates of dogs for each method, data was collected from Hillcrest Animal Clinic. The data suggested that neither transcervical insemination nor surgical insemination was significantly better than the other. 50% of the dogs conceived when inseminated using the transcervical method, and 54.5% of the dogs conceived when inseminated using the surgical method. Based on the results, more data needs to be collected on both insemination procedures to …

Influence Of Fertilizer Rate On Swollen Stem Formation (“Bulbing”) And Vitamin C Content In Different Kohlrabi Cultivars, Mark Iradukunda, Paul E. Read

Honors Program: Senior Projects (Public)

Kohlrabi (Brassica oleracea Gongylodes Group) is a vegetable crop found in the Brassicaceae, and it is rich in antioxidants such as vitamin C. Vitamin C helps in oxidative damage repair and strengthens the immune system, so exploring vitamin C sources may contribute to improving human health. The objective of this study was to determine the effect of different fertilizer rates on kohlrabi yield, in terms of the swollen stem and the vitamin C content, and if those effects are similar in different kohlrabi cultivars. In this greenhouse study, we fertilized four potted kohlrabi cultivars with a common water-soluble greenhouse fertilizer …

Bacteriophage That Infect Gordonia Species Show Varying Host Specificity And Infection, Lindsay Birge

Honors Program: Senior Projects (Public)

Bacteriophage (phage) are an incredibly abundant species of virus that infect bacteria. One major characteristic of phage is their small host range- many phage are known to infect only one or a few hosts. This phage and host relationship has led to phage therapy recently becoming highlighted as a possible alternative to traditional antibiotics in light of the growing antibiotic resistance crisis. The study of phage host specificity has risen in line with this concept, as a phage with a more extensive host range can provide more opportunities for use as an antibiotic. Samples of phage previously isolated on a …

The Crucial Role Of Sestrins In Oxidative Stress Response And Disease: An Analysis Of Phosphorylation Mutation S110a In Hsesn2, Julianne Fay

Honors Program: Senior Projects (Public)

Sestrins are highly conserved proteins which are induced under environmentally stressful conditions to adjust the cell’s response to such disturbances. This protein possesses two domains critical for its dual function in reducing reactive oxygen species (ROS) and regulating the mTORC1 complex. Sestrins may use diverse transcription factors, such as Nrf2, peroxiredoxin reductase activity, and a catalytic cysteine to regenerate oxidized species; however this was confirmed to be through a mechanism likely different than AhpD, for which there was distance sequence similarity. Furthermore, Sestrins are important regulators of TORC1 and AMPK, which are crucial energy sensors able to control cellular metabolism …

Genomic Analysis Of Acetoanaerobium Sp. Vlb-1, An Anaerobic Bacterium Isolated From Nebraska's Eastern Saline Wetlands, Claire Martin

Honors Program: Senior Projects (Public)

Through the analysis of genetic code, the genomic and physiological characteristics of an environmental anaerobic bacterial isolate, Acetoanaerobium sp. strain VLB-1, can be determined and significant pathways can be identified in its significance to the environment. This particular organism was isolated from the Eastern Saline Wetlands in Lincoln, NE. With this isolate, an investigation into elemental and amino acid cycling via the Stickland reaction and the Wood-Ljungdahl pathway was conducted to determine possible metabolic products. The Stickland reaction is a relatively newly discovered pathway, observed in the genus Clostridium. A. sticklandii is the main model for this method of …

Targeting Transgenic Proteins To The Mitochondria In Plants, Susan Qudus, Jeffrey P. Mower

Honors Program: Senior Projects (Public)

Cytoplasmic male sterility (CMS) in plants can convert an individual into female through sterilization of the male reproductive parts, creating an inability to produce functional pollen. In nature, this is advantageous for genetic diversity and producing progeny with unique genes that may be beneficial in evolution. For agriculture, this method is preferential for selection of desirable traits in crops when cross breeding. CMS is typically caused by genes in the mitochondrial DNA (mtDNA), such as novel open reading frames (ORFs) that form after imperfect repair of double-stranded breaks in the mtDNA. Specific CMS genes vary among various plant species. It …

Can Gdp Be Predictive Of Fertility Rates In Sweden?, Hannah Coleman

Honors Program: Senior Projects (Public)

Fertility rates in a country vary and can be influenced by numerous different aspects of an individual’s life and the society in which they live. One aspect that may influence fertility rates at the national level is the gross domestic product (GDP). GDP is an indicator of a country’s economic productivity. Because fertility is linked to both economic development and individual resources, GDP may be a useful indicator of fertility rates. If so, knowing or predicting GDP could be used to project the fertility rates of a population years into the future. To determine if a reasonable connection between GDP …

Virtual High School Physiology: Hands-On Experiences During The Covid Pandemic, Sowmya Anjur

Faculty Publications & Research

The CoVID pandemic has forced us to rethink our curriculum and allow for many unforeseen factors. Going virtual since March has affected teaching and learning and made it almost impossible for students to perform hands-on learning. My school is a residential school for students in grades 10-12 and since we cannot have students congregating on campus, and possibly spreading the virus, we went virtual. We have had to revamp our curriculum and change our teaching to engage students online. The question then becomes - how do we promote equity, diversity and inclusion through online learning, knowing that many of our …

A Mathematical Model Of Pancreatic Cancer Growth And Response To Treatment, Allison Cruikshank

Honors Program: Senior Projects (Public)

Pancreatic cancer is one of the leading causes of death due to cancer in the United States. Analyzing the effects of radiation is extremely valuable in determining when a patient is allowed surgical resection, which is, presently, the only potentially curative treatment for pancreatic cancer. This study examines pancreatic tumor growth and shrinkage to predict tumor response and change of resectability for pancreatic cancer patients undergoing radiation therapy. This is done using ordinary differential equations as a mathematical model. Mathematical models have increasingly been applied to various biological systems/processes to analyze the principles involved. In our project, a population dynamical …

The Importance Of Nutrition And Preventing Malnutrition In Older Adults: A Literature Review And Informational Booklet, Sophie Johnson

Honors Program: Senior Projects (Public)

Over years of studying nutrition science and gerontology, there was very little information in classes that combined these two important topics. Older adults are often classified as those above the age of 65 years old. There is a growing number of older adults in the United States, which increases the need for information on how nutrition and aging are interlaced. As humans age, multiple factors can impact nutrition. Nutrition involves consuming the proper amount of nutrients to maintain body function. There are physiological, physical, socioeconomic and medication factors that can all influence nutrition status. It is important to be aware …

A Kinesiological Analysis Of Dancers At The University Of Nebraska-Lincoln, Vanessa Reiser

Honors Program: Senior Projects (Public)

Supplemental conditioning can improve a dancer’s performance of important skills without taking away from class and rehearsal time. To investigate this further, an individualized conditioning plan based on a specific skill was created for eight student dancers, and the effects were analyzed using a survey and rating scale by a trained dance professor. The results showed improvement of skills for the majority of dancers, along with improved fitness in qualities such as strength and balance. In conclusion, individualized conditioning plans based on a specific skill may benefit student dancers who are juggling intense class and rehearsal schedules.

Spatiotemporal Interactions Between Deer And Cattle, Sydney Brewer

Honors Program: Senior Projects (Public)

Mule deer, white-tailed deer, and cattle are sympatric on the landscape throughout many portions of Nebraska and encounter each other in time and space. By considering variation in daily activity patterns and non-random patterns in the timing of passage through specific locations, we can better understand whether animals may be avoiding each other temporally when sharing space. I investigated temporal activity patterns and avoidance/attraction ratios to investigate if deer altered their activity patterns in the presence of cattle and if they exhibited avoidance at a study site near McCook, Nebraska, USA. We collected data from 19 game cameras that were …

Diversity And Inclusion In The Science Classroom, Sowmya Anjur

Faculty Publications & Research

A Diversity, Epidemiology and social justice unit was incorporated into the Physiology and Disease curriculum in Fall 2016. Students discussed topics such as social and cultural influences on diversity thinking, and selective treatment in hospitals based on race. It was very noteworthy that students were united in their thinking regarding diversity and inclusion, despite the fact that they were from different backgrounds and diverse cultures. In 2017, additional discussions were held on equity in education. Students who were otherwise reserved were encouraged enough to express their views, and everyone appreciated the fact that they had been included.

The Critical Need For Mental Health Education To Be Mandated In New Mexico's Public Schools, Bonnie L. Murphy

Shared Knowledge Conference

Based on a review of research and best practices in mental health awareness and skills, this inquiry project argues for state legislative policies that would require mental health awareness and skills in the K-12 curriculum. Mental health affects individual accomplishments in every stage of people’s lives beginning in early childhood and throughout the life cycle. Prevention and treatment of mental illness plays a key role in the ability of an individual to cope with loss and develop resiliency and perseverance in challenging times and to make better decisions that improve the individual’s life and the lives of those around them. …

"My Paintings Would Be No Different Than A Picture In A Biology Textbook", Andi Kur

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

I find that there are innate balances in life, universal dichotomies that permeate our understanding of the world. My paintings are about a duality such as this that exists between art and science. We are told from youth that these subjects are poles in constant strain, as miscible as oil in water. I spent thirteen years in school believing that I must choose between the two, that it is unnecessary to carry both with me. Drawn between a distinct love of each, I realized how vehemently I disagreed. Everything: every rock to every tree to every person is suspended between …

Evolutionary Explanation For Invasive Abilities Of Centaurea Stoebe (Spotted Knapweed) In Introduced Areas, Erin Koren

UReCA: The NCHC Journal of Undergraduate Research and Creative Activity

Since every invasion and every exotic species presents a new challenge with novel invasion strategies, the invasion of Centaurea stoebe (synonymously referred to as C. maculosa) into North America will be used as a case study to deeply examine invasion strategies. Centaurea stoebe is a short-lived (approximately 3 years) perennial member of the aster family (Broz et al., 2007). It occurs in two different cytotypes, or with two different chromosomal factors. In its home range, it exists in both diploid and tetraploid cytotypes, but only the tetraploid version is present in introduced ranges in North America (See Figure 1; Treier …

Science & Spaghetti Monsters: Understanding The Nature Of Scientific Knowledge & Research, Sarah O'Leary-Driscoll

Nature of Science

What is science?

When students are asked to define science, many of them define science as “a body of knowledge gained by performing experiments.”

A more appropriate definition, however, is that “Science is … a process of inquiry aimed at building a testable body of knowledge open to rejection or confirmation” (Shermer, 2005).

There are three important points that this definition makes:
