Bio 340 Final Project: Effects Of Zoning On Fish Density Along The Great Barrier Reef, Mary Lamoriello

Biology Student Scholarship

Mary Lamoriello - Environmental Biology '27

Over the years, there have been many marine parks and restricted fishing zones established along the Great Barrier Reef to maintain biodiversity and coral health. The goal of these zones is to create an ”undisturbed” area, where species can flourish. Many different species reside in this reef and play important ecological roles. Parrotfish help maintain coral health by grazing on algae, and the presence of carnivores often indicate a diverse and healthy ecosystem. This project aims to examine the differences in species distribution between zones along the Magnetic Island, by looking at carnivorous and …

Bio 340 Final Project: Rural Population Structure And Food Production Interact To Shape Global Undernourishment, Ava Ripanti

Biology Student Scholarship

Ava Ripanti - Environmental Biology '27

Undernourishment remains a major global public health challenge, reflecting the proportion of a population lacking sufficient dietary energy intake. While food availability is central to food security, undernourishment is also shaped by structural and socioeconomic factors such as population distribution and access to resources. Although rural populations are closely tied to agriculture, they often experience higher food insecurity due to limited infrastructure, market access, and healthcare. Prior research emphasizes that broader determinants, particularly inequality and development, are stronger predictors of undernourishment than agricultural output alone, that food insecurity exists in both rural and urban …

Bio 340 Final Project: Effects Of Light Pollution On Bat Activity, Cael Schneider

Biology Student Scholarship

Cael Schneider - Environmental Biology ‘28

Artificial light at night (light pollution) is an increasing consequence of urbanization and can disrupt nocturnal wildlife. Bats are especially susceptible, as they rely on dark skies for navigation, predator avoidance, and foraging. The effects of artificial light may vary among species due to differences in foraging strategies, habitat use, and light tolerance.  Previous research has documented negative effects of artificial light on bat foraging, roosting, breeding, and hibernation. However, some species, such as red bats, may forage near artificial lights where insects are abundant. Species including the big brown bat, hoary bat, and …

Bio 340 Final Project: A Comparative Analysis Of German And French Energy Policy, Adam Garies

Biology Student Scholarship

Adam Garies - Environmental Biology ‘28

European energy systems have undergone rapid transformation over the past two decades, with countries adopting different strategies to reduce carbon emissions. This divergence is particularly evident between Germany and France. Following the Fukushima disaster in 2011, Germany accelerated its nuclear phase-out, while France has declared its commitment to nuclear energy. Nuclear energy however, is an important step towards reducing carbon emissions. Excluding nuclear energy from energy plans will lead to a rise in reliance on potent fossil fuels like coal and natural gas, resulting in greater carbon emissions, even with an emphasis on expanding …

Life Histories Of Two Sgcn Procambarus Species In East Texas, Mckenzie A. Adkins

Biology Theses

Within freshwater systems, crayfish play notable roles by shaping habitats and linking food web levels. Yet even with such influence, knowledge about numerous species is incomplete, which hinders protection strategies. Found only in the Neches River basin in eastern Texas, Procambarus nechesae and Procambarus nigrocinctus have different conservation statuses, mainly because data on their life history remains sparse. These two species are not closely related and are analyzed independently in this study. Research into traits tied to survival and environmental preferences was carried out so that informed decisions on conservation efforts can be made for these species. The goal of …

Bio 340 Final Project: Artificial Reef Effects On Fishing Productivity, Griffin Gouck

Biology Student Scholarship

Griffin Gouck - Environmental Biology '26

A slew of artificial reefs can be seen dotting the Gulf of America. Some result from catastrophic shipwrecks and others from construction dumping; however, all provide an opportunity for the development of marine ecosystems. The question of how artificial reefs effect local fish populations is an expansive concept extremely hard to simplify down to a basic relationship. The development of reefs is a delicate process taking place over many years of growth. Previous studies utilized a combination of resources like theoretical models, field data and comparisons to natural reefs to study how these artificial …

Impacts Of Salinity On Microbial Enzyme Activity In Coastal Waters, Natali Ariyoshi

Honors Theses

Microbial extracellular enzymes are critical for the breakdown of organic matter and nutrient cycling in aquatic ecosystems. Extracellular enzyme activity serves as an indicator of nutrient turnover rates, metabolic states, and nutrient limitations within an ecosystem. Coastal ecosystems are especially dynamic as the influx of freshwater from inland runoff or seawater intrusion from storm surges can lead to fluctuations in salinity which can restructure microbial communities and alter enzymatic activity. Despite the ecological significance of these changes, few studies have explored the effects of short-term salinity shifts on microbial extracellular enzyme activity in coastal waters. This study investigated the effects …

Proximity Data And Social Networks: A Validation Study Of Two Models Of Mobile Dataloggers In The Semi-Fossorial And Social Rodent, Octodon Degus, L. D. Hayes, A. A. Maldonado-Chaparro, Jessica Morales Valenzuela, L. Platt, L. A. Ebensperger

Biology Faculty Works

The use of mobile dataloggers to gather proximity data has generated novel insights into the social network structure of animals. The performance of mobile dataloggers may be impacted by different environmental and social conditions. Thus, validation studies that account for species-specific habitat use and behavior are essential. We conducted a series of validation studies of two brands of mobile dataloggers (Gipsy6, Technosmart, Italy; ProxLog, IoSA, Belgium) on the semi-fossorial rodent, Octodon degus. First, we determined the sensitivity of both types of dataloggers to track position and closeness in different habitats (Experiments 1 and 2). To determine if the structure …

Biology Faculty Publications and Presentations

Foliar endophytes contribute to plant nutrient acquisition, stress tolerance, and pathogen resistance, yet their responses to ecosystem-level processes remain poorly understood. Using a space-for-time substitution design, we investigated bacterial and fungal community dynamics in the foliar endosphere of four phylogenetically distinct plant hosts across a well-characterized successional chronosequence.

Studying More, Not Less: Rethinking Test Anxiety In Undergraduate Biology Courses, Kailey E. Reeves

Honors Theses

This study investigates the relationships among test anxiety, study behaviors, and metacognitive evaluation in undergraduate biology courses. While prior research has established that study strategies and metacognition influence academic performance, less is known about how these factors interact with test anxiety in undergraduate Biology courses. Guided by the student approaches to learning (SAL) and metacognition frameworks, this study examines whether test anxiety is associated with the type and number of study strategies students use, as well as their ability to evaluate their own learning and preparedness. Using a convergent parallel mixed-methods design, data was collected from 205 students enrolled in …

A Survey Of Lichen Native To Three Of Mississippi’S National Forests, William S. Granberry Iii

Honors Theses

Lichens are a major part of the environment for telling the air quality and the impact humans have on the environment. These signs go into how many species of lichen are present in a general area, and there has been a lack of a list of lichens that call Mississippi their home. The goal of this research is to help create this list through a survey of lichen in three of Mississippi’s National Forests: DeSoto, Homochitto, and Holly Springs. These three forests are ideal because they cover differing ecosystems and are in different parts of the state, heightening the chance …

Mechanisms Underlying Diversity In Bacterial Biofilms, Jacob David Holt

Dartmouth College Ph.D Dissertations

Bacteria commonly exist in natural environments as communities of multiple strains and species attached to surfaces and encased in an extracellular matrix of DNA, protein, and polysaccharides–termed biofilms. These biofilms contribute to diverse functions, from ocean carbon cycling via chitin degradation to pathogenic processes such as wound or implant colonization. The molecular mechanisms governing biofilm formation and composition have been well characterized in model pathogenic organisms, yet the extent to which aspects of biofilm formation contribute to the assembly and maintenance of diverse communities remains less well understood. Using microfluidics, confocal microscopy, and model biofilm-forming bacteria, this thesis details how …

Community Composition Of Antibiotic-Resistant Bacteria On The Mississippi Gulf Coast, Marisa Martin, Colin Jackson

Honors Theses

The Mississippi Gulf Coast is an important resource for transportation, economic development, and recreation. Given its economic and cultural importance, it is crucial to maintain clean and safe conditions along the coast for public health, but other than routine beach monitoring, few studies have examined microbial contamination of coastal waters in this region. This study aimed to determine the quantity, composition, and distribution of bacteria resistant to six different antibiotics (Vancomycin, Kanamycin, Tetracycline, Ciprofloxacin, Erythromycin, or Amoxicillin) in seawater at seven public beaches along the Mississippi Gulf Coast. No bacteria resistant to Ciprofloxacin were detected, and bacteria resistant to Kanamycin …

From Sunshine To Sight Lost: Amd In North Dakota, Sidney J. Leciejewski, Diane Darland

Arts & Sciences Undergraduate Showcase

Age-related macular degeneration (AMD) is a progressive eye disease that directly harms the macula, which could eventually cause vision loss. The macula is an area on the back of the eye that contains cone cells, which allow for our color vision. Its location also allows us to have our central vision. There are two kinds: the dry and wet form, where the wet form is more extreme. The disease, itself, is highly prevalent in North Dakota, which is why it is important to note its causes and prevention methods. Some causes of AMD include genetic risks,  health risks, and metabolic …

The Longevity Of Dna From Bloodstains And Its Forensic Implications, Nadia Walter

Senior Honors Theses

Human DNA is valuable forensic evidence, helping to solve a wide range of cases. It is often sourced from biological fluids found at a scene such as blood, saliva, semen, and urine. Many different factors can influence the longevity of DNA sourced from bloodstains, including the type of substrate, storage conditions, and weather. The quality of a DNA sample from a bloodstain found at a crime scene may influence its admissibility in court.

Original research was done on a surgical table from the last major battle of the American Civil War, extracting DNA from latent bloodstains. Some full profiles were …

Acquisition Behavior Response: Investigating The Ability Of Leptoglossus Phyllopus To Choose Between A “Good” Versus “Sub-Optimal” Strain Of Caballeronia, Irene L. Pham

2026 Spring Honors Capstones Projects

Leptoglossus phyllopus is a polyphagous pest that primarily feasts on citrus, tomatoes, and legumes. They must form a mutualistic symbiosis with Caballeronia every generation by ingesting the bacterium from their environment. However, not all species of Caballeronia confer the same fitness on the L. phyllopus host, raising the question of whether L. phyllopus possesses a partner choice mechanism that would allow it to distinguish between a good (GAOX1) and a suboptimal (Lep1P3) symbiosis partner. This was examined by conducting a choice experiment in which the two symbionts (GAOX1 vs. Lep1P3) were placed in a plastic box, and the bug’s roaming …

Attentional Mechanisms Of Language In Infants With Down Syndrome, Fragile X Syndrome And Siblings Of Children With Autism, Isabelle Robinson

Caravel Undergraduate Research Journal

Children with Down syndrome (DS), fragile X syndrome (FXS), or younger siblings of a child with autism spectrum disorder (ASIB) often exhibit atypical object exploration and social engagement, which can affect important learning opportunities. The purpose of this study was to examine group differences in social attention shifting and attentional disengagement between infants with DS, FXS, and ASIBs. This study utilized data from a longitudinal study collected from 12-month-old infants with DS (n = 13), FXS (n = 14), and ASIBs (n = 24).

Examining Biobehavioral Indicators Of Adhd In Children With Fxs, Hannah Pressler, Kayla Smith, Ramsey Coyle, Elizabeth Will, Jane E. Roberts

Caravel Undergraduate Research Journal

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity behaviors that are inconsistent with developmental age. Children with fragile X syndrome (FXS), a genetic neurodevelopmental disorder, are often diagnosed with comorbid ADHD (53–59% of males with FXS). Despite the prevalence of ADHD in FXS, little is known about the early manifestation of ADHD. The current project aims to explore group differences in play behaviors between children with FXS and typically developing (TD) children as well as the relationship between infant play behavior and heart activity to future ADHD attention outcomes. Participants included male children with FXS and …

Early Behavioral And Physiological Predictors Of Autism In 12-Month-Old Siblings Of Children With Autism, Nicolas Poupore, Kayla Smith, Abigail L. Hogan, Jane E. Roberts Ph.D.

Caravel Undergraduate Research Journal

Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by social-communicative deficits and repetitive behaviors. Complementing behavioral (i.e., The Autism Observation Scale for Infants (AOSI) scores) and physiological markers (i.e., respiratory sinus arrhythmia (RSA), heart rate (HR)) may improve early identification of ASD and provide insights into the neurobiological mechanisms contributing to early ASD symptoms. Younger siblings of a child with ASD (ASIBs) had significantly higher AOSI Total Scores and AOSI Marker Scores in comparison to Low Risk Controls (LRCs). RSA significantly decreased from a Baseline to AOSI for both groups, but only for the ASIB group was a negative …

The Cranial Morphology Of Large Wild Versus Captive Felids, Bryttin Boyde, Hannah Selvey

Caravel Undergraduate Research Journal

Studies have shown that carnivores in captivity that are fed soft diets have more periodontal problems and that the morphology of their skeletons, skulls specifically, responds to environmental and behavior factors. Considering that captive diet affects teeth and gums, we have conducted research on Dr. Adam Hartstone-Rose’s hypothesis that variation will also be discernible through the examination of cranial morphology. We compared captive and wild lions Panthera leo and tigers Panthera tigris to see if differences were present, then analyzed data collected by a microscribe using a 3D morphometric analysis program. Next, Principal Component Analysis was completed to account for …
