Socio-Ecological Interactions Promote Outbreaks Of A Harmful Invasive Plant In An Urban Landscape, T. Trevor Caughlin, Matthew Clark, Louis W. Jochems, Nick Kolarik, Andrii Zaiats, Cody Hall, Jason M. Winiarski, Breanna F. Powers, Martha M. Brabec, Kelly Hopping

Biology Faculty Publications and Presentations

1. Urban landscapes often harbour organisms that harm people and threaten native biodiversity. These landscapes are characterized by differences in socioeconomic context, habitat suitability and patch connectedness. Identifying which spatial differences enable outbreaks of pests, pathogens and invasive species will improve targeted control efforts.

2. We tested hypotheses to explain the distribution and demography of puncturevine Tribulus terrestris, a human-dispersed invasive plant in Boise, a city in the western United States. We hypothesized an increase in puncturevine infestations near low-valued properties with a high proportion of bare ground, the species' preferred microhabitat, that are well connected on the urban road network. …

Coyote Occupancy And Movement In Hanover County, Virginia, Richard S. Groover

Virginia Journal of Science

Although the coyote (Canis latrans) is native to North America, we have limited understanding of its presence in Virginia. Coyote range expansion is linked to anthropogenic factors, including habitat fragmentation and the extirpation of apex predators. Information on coyote adaptations to Virginia habitats is scarce, and eastern coyotes may have unique adaptations for colonizing an area. Anecdotal evidence suggests that coyotes are abundant in Hanover County (north of Richmond, VA), but this has not been confirmed. This study was conducted over an 18-month period with multiple survey sites throughout Hanover County, each equipped with game camera stations and …

Memory Acquisition By Brainless Juvenile Terrestrial Planarians (Bipalium Kewense), Christina Chueiri, Christine Gildea

Transformations: Presentation Slides

Learning is how organisms build and store memories in their brains to aid them in survival. This process occurs as organisms experience new stimuli. Bipalium kewense, a terrestrial planarian, has a very minimal central nervous system. The nervous system of planarians consists of only two nerve cords and two ganglion which serve as a “brain.” This species reproduces by segmenting a small piece of their posterior end as a fragment, which initially lacks most adult structures. The fragments must regenerate the head, brain, mouth, functioning digestive system, and reproductive organs. To determine where memory is stored in these terrestrial planarians, …

The Importance Of Translationally Evaluating Steroid Hormone Contributions To Substance Use, Erin E. Maher, Ashley Strzelecki, Jessica J. Weafer, Cassandra D. Gipson

Markey Cancer Center Faculty Publications

Clinically, women appear to be more susceptible to certain aspects of substance use disorders (SUDs). The steroid hormones 17β-estradiol (E2) and progesterone (Pg) have been linked to women-specific drug behaviors. Here, we review clinical and preclinical studies investigating how cycling ovarian hormones affect nicotine-, cocaine-, and opioid-related behaviors. We also highlight gaps in the literature regarding how synthetic steroid hormone use may influence drug-related behaviors. In addition, we explore how E2 and Pg are known to interact in brain reward pathways and provide evidence of how these interactions may influence drug-related behaviors. The synthesis of this review demonstrates the critical …

Dairy Science and Food Science Faculty Publications: 2022 to Present

The probiotic foods market is growing exponentially; however, probiotics’ survivability and interaction with product attributes pose major challenges. A previous study of our lab developed a spray-dried encapsulant utilizing whey protein hydrolysate-maltodextrin and probiotics with high viable counts and enhanced bioactive properties. Viscous products such as butter could be suitable carriers for such encapsulated probiotics. The objective of the current study was to standardize this encapsulant in salted and unsalted butter, followed by storage stability studies at 4 ◦C. Butter was prepared at a lab-scale level, and the encapsulant was added at 0.1% and 1%, followed by physiochemical and microbiological …

Coordination Of Hydraulic And Morphological Traits Across Dominant Grasses In Eastern Australia, Robert J. Griffin-Nolan, Jeff Chieppa, Alan K. Knapp

Biology

1. Leaf hydraulic traits characterize plant drought tolerance and responses to climate change. Yet, plant hydraulics are biased towards northern hemisphere woody species. We collected rhizomes of several perennial grass species along a precipitation gradient in eastern Australia and grew them in an experimental pot study to investigate potential trade-offs between drought tolerance and plant morphology.
2. We measured the following leaf hydraulic traits: the leaf water potential (Ψleaf) at 50% and 88% loss of leaf hydraulic conductance (P50Kleaf and P88Kleaf), the Ψleaf at 50% loss of stomatal conductance (P50gs), leaf turgor loss point (TLP), leaf dry matter content (LDMC), leaf modulus …

Effects Of Diet On Lcn2 Expression And Onset Of Neuroinflammation In An Alzheimer’S Disease Mice Model, Abdirahman A. Hayir

Neuroscience Honors Projects

This project covers the findings regarding the impact of diet on lipocalin 2 (LCN2) and the effects it has on neuroinflammation Alzheimer’s Disease (AD). LCN2 is a protein that is critical to the functionality of mitochondria and inflammatory responses. Evidence has shown that mitochondrial dysfunction is a potential central event in driving AD pathogenesis and contributing to formation of pathological hallmarks such as chronic inflammation. Furthermore, studies have shown that LCN2 can be deficient under metabolic conditions such as high-fat-diet (HFD). This study investigates if HFD induces LCN2 deficiency and increased neuroinflammation in an AD mice model.

Effects Of Heavy Metal Uptake On Growth, Chlorophyll Content, And Calcium Oxalate Crystals In Lemna Minor (Duckweed), Olivia F. Miller

Undergraduate Honors Thesis Projects

Lemna minor L., duckweed, is a common aquatic plant used for the phytoremediation of wastewater. Heavy metal contamination poses a significant issue, and numerous studies have been conducted on the efficiency of L. minor’s hyperaccumulation ability of these metals. Calcium oxalate crystals are an important aspect of the growth and development of L. minor, but how they are influenced by the uptake of heavy metal has not been extensively studied. This study aims to determine the effects that lead, cadmium, and copper have on the formation of calcium oxalate crystals, vegetative growth, and chlorophyll a and b content on L. …

Fusarium Isolates Adapt To Specific Wheat Tissues, Liam Kent, Mara Krone, Santiago Mideros

PRECS student projects

Introduction

Tissue specificity is a pathogen’s preference for infecting one section of tissue (i.e., root, stem, or head) over another. 1 Having a better understanding of a pathogen’s ability to cause disease on specific tissues could contribute to new mechanisms of disease control. This will allow growers to make the best decision on effective pathogen management. In 2022, Fusarium isolates were collected from wheat heads and roots across Illinois. These isolates were used in a pathogen aggressiveness assay on wheat roots, in an in vitro growth rate experiment , and in the development of a spore quantification protocol. The phenotypic …

Role Of Age And Sex In The Effects Of Repeated Methamphetamine Exposure On Hedonic Tone In Sprague Dawley Rats, Cameron Lewis, Conor Strumberger, Joshua M. Gulley

PRECS student projects

Anhedonia is defined as a reduced or complete loss of pleasure from a previously pleasurable stimulus, and it is comprised of two dimensions:

• Hedonic anhedonia consists of a distinct loss of pleasure in consumption of a normally pleasurable stimulus.
• Motivational anhedonia involves the goal directed behavior to obtain a reward.

Withdrawal induced anhedonia following use of methamphetamine (METH) is thought to contribute to relapse behaviors^1,2 . The anhedonic effects of drug withdrawal largely depend on dose, frequency, and the duration of drug exposure^4,5,6.

The role of sex and age of exposure in this context has yet to …

The Tomato Strikes Back: Plant Response To Environmental Stress, Maya K. Davis, Erinn Dady, Esther N. Ngumbi

PRECS student projects

Introduction

• Tomato is an important vegetable. Its production is threatened due to altered weather patterns which increase environmental stressors such as flooding^{1, 2} and herbivory³ to crops.
• Plants respond in many ways. Stressed plants strike back to environmental stress by altering their chemistry⁴:

1. Volatile Organic Compounds (VOCs) emissions
2. Defensive secondary metabolites²

• Stress induced physiological changes in plants impact growth and development of insects.
• This study is broken into two experiments:

1. The plant response to flooding stress
2. The insect performance on flooded plants

Potential Implications Of Elevated Co2 For Enhanced Rock Weathering In Croplands, Hannah Maher, Megan Allen, Lisa Ainsworth

PRECS student projects

• Atmospheric carbon dioxide (CO₂) levels are increasing by 2.37 ppm year, and levels have increased from about 370 ppm in 2000 to about 420 ppm in 2023¹
• Increased CO₂ levels result in climate change, including increased temperatures and drought which impacts soybean crops
• Enhanced Rock Weathering (ERW) is the process of spreading basalt on fields to accelerate the natural reaction between rocks, CO2, and water²

On The Reproducibility Of Power Analyses In Motor Behavior Research, Brad Mckay, Mariane F. B. Bacelar, Michael J. Carter

Kinesiology Faculty Publications and Presentations

Recent metascience suggests that motor behavior research may be underpowered, on average. Researchers can perform a priori power analyses to ensure adequately powered studies. However, there are common pitfalls that can result in underestimating the required sample size for a given design and effect size of interest. Critical evaluation of power analyses requires successful analysis reproduction, which is conditional on the reporting of sufficient information. Here, we attempted to reproduce every power analysis reported in articles (k = 84/635) in three motor behavior journals between January 2019 and June 2021. We reproduced 7% of analyses using the reported information, …
