Transcriptional Regulation in the Uterine Luminal Epithelium

Evelyn A. Carrion

Advisor: Richard R. Behringer, PhD

Abstract

The uterus is an organ comprised of multiple tissues that are essential for women’s health and reproduction. The uterus is composed of multiple tissue layers, including the perimetrium, myometrium, and the endometrium. The endometrium is the inner lining of the uterus, and contains the luminal epithelium, glandular epithelium, and stroma. The luminal epithelium is a simple columnar layer of cells that is necessary for embryo implantation. The uterus is derived in part from the embryonic precursor tissue called the Müllerian duct. There are no …

The Helminthic Status Of Selected Tanzanian Subterranean Rodents, The Root-Rats (Spalacidae: Tachyoryctes Splendens) And Emini Silvery Mole-Rats (Bathyergidae: Heliophobius Argenteocinereus Emini), Jestina V. Katandukila

Tanzania Journal of Science

Root-rats (Tachyoryctes splendens) and emini silvery mole-rats (Heliophobius argenteocinereus emini) are common subterranean rodents that are essential component of the ecosystem. They serve as prey for small to medium-sized carnivores and birds of prey but their role as hosts to parasites is limited. The present study, explored the Gastrointestinal Tract (GIT) contents of 40 rodents (20 T. splendens and 20 H. a. emini, respectively) to acquire information on parasites diversity of these mammals. The GIT contents from subterranean rodents in a sex ratio of 1:1 were examined under a compound microscope to isolate helminths. The isolated helminths belonged to the …

Imidacloprid Effects On The Survival And Cutaneous Microbiome Of Northern Leopard Frogs, Evelyn Margaret Osterloo

Honors Thesis

Amphibians are experiencing population declines due to habitat loss, climate change, and diseases, particularly chytridiomycosis caused by the fungus Batrachochytrium dendrobatidis. Protection from this fungal infection stems from the cutaneous microbiome. Pesticides have been shown to affect amphibians in a variety of ways, including reducing survival, locomotor performance, and accumulation in body tissues. Pesticides may also lead to changes in the cutaneous microbiome affecting amphibians who rely on these organisms as an anti-Bd defense mechanism. To investigate the effect of imidacloprid, a neonicotinoid insecticide, Northern Leopard frogs (Lithobates pipiens) were subjected to sublethal concentrations (control = …

Systematics Of Disk-Winged Bats (Thyroptera), Courtney L. Klumpp

Capstone Showcase

This thesis investigates the evolutionary relationships among disk-winged bats in the genus Thyroptera, a small group of Neotropical bats known for the adhesive suction disks on their wings and feet that allow them to roost inside tightly rolled leaves. The distinctive morphology and behavior of these bats have not been extensively documented, and their phylogenetic relationships remain only partially resolved. The goal of this research is to better understand how these species are related to one another and to determine whether the five recognized species of Thyroptera form a single monophyletic group. To address this question, morphological and genetic …

Measuring Welfare Of Wild Tarantulas During Field Surveys Using Heart Rate, Tim Angelo Artiaga Lopez, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Tarantulas (Theraposidae) are predatory arachnids that can help control populations of herbivorous arthropods. We have been monitoring populations of the Missouri brown tarantula (Aphonopelma hentzi) in Missouri glades for three seasons and have questions about their welfare during these surveys. Unlike mammals, arthropods are not extensively researched and there are only a few known facts about measuring their welfare. Managing stress for wild animals during field surveys is important for reducing the potential negative impacts of research. In mammals, increased heart rate is positively correlated with negative stress and eustress. Using the same logic, we hypothesized that heart rate could …

Life History And Distribution Of Two Species Of Cownose Ray, Rhinoptera Bonasus And Rhinoptera Brasiliensis, In Mississippi Coastal Waters, Anna Millender

Master's Theses

Historically, the American Cownose Ray (Rhinoptera bonasus) was considered the only rhinopterid residing in the northern Gulf of Mexico (GOM); however, recent studies have confirmed the presence of the Brazilian Cownose Ray (Rhinoptera brasiliensis) throughout this region. The current study investigated the life history and distribution of both species within Mississippi waters, an area that previously represented a data gap for both species. From April 2016 – July 2025, 193 R. bonasus and 94 R. brasiliensis were analyzed to describe the reproductive biology. Reproductive timing, mating, gestation length, and parturition were similar among species. Although more …

Field Journal: The Excluded Middle, Carrie E. Kouts

Masters Theses

What does it look like to engage with organisms and landscapes at the periphery of anthropocentric value structures? How does one break the internalized myth that the “built” environment is excluded from the natural world? When does a hyper-mobile and hyper-commodified society confront the exponential crisis of animal death? Within this series of journal entries, field notes, collection observations, weird prose, and sensory musings, one will find questions on the nature of being human and the complex narratives of care we encounter in a world shared with more-than-humans. Each handwritten vignette and photograph from daily life weaves a non-linear and …

Ghosts In Glass: Ghost Crabs As Judges Of Glass Sand For Coastal Restoration, Emily Parrish

Honors Theses

Over 60% of the Gulf of Mexico coastline is actively eroding, which has resulted in thousands of miles of lost coastline over the last 100 years. This drastic loss of coastal land highlights the dire need for coastal restoration across the entirety of the Gulf Coast. A vital aspect of restoring these eroded areas is replenishing eroded substrate, traditionally conducted through offshore dredging of substrates which comes with high economic and ecological costs. Recycled glass sand may be able to fill this role and reduce our reliance on dredging while lowering the amount of glass waste entering landfills each year. …

Diversity And Habitat Use Of Bats In Modified Suburban Landscapes, Brittany Morgera

Biology Presentations

Bats occupy critical ecological niches and perform important ecosystem services like controlling insect populations. However, humans have altered bat habitat substantially, resulting in the reduction of bat populations. The goals of this research are to assess bat diversity and habitat use across different levels of suburban habitat modification. To accomplish this, we deployed passive acoustic recorders at twelve locations with varying human impact in Montgomery County, Pennsylvania. In accordance with The North American Bat Monitoring Program’s standards, acoustic analysis software was used to identify bat species. Manual identification methods from The Canadian Wildlife Health Cooperative were used to verify these …

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn

Journal of Earth and Life Science

How white-tailed deer use the landscape in an urban environment can help us understand the effects of urbanization on deer populations. White-tailed deer form observable matriarchal hierarchies in studied populations. This study examines the matriarchal structure, home range size, and home range composition of 25 collared white-tailed deer within the city limits of Bemidji, MN. The results found no significant difference between age class and home range size or composition. However, movement metrics from yearling and mature age classes were more similar than the juvenile age class females. I propose this is because social acceptance between mature females was higher …

Exploring The Effects Of Road Salt On Earthworm Species, Alea Mry Koston

Williams Honors College, Honors Research Projects

This study examines the effects of two road salts, sodium chloride (NaCl) and calcium magnesium acetate (CMA), on the health of two earthworm species: Eisenia fetida and Lumbricus terrestris. Over a 4-week period, approximately 168 earthworms were exposed to varying concentrations of either NaCl, CMA, or mixed ratios of both, with a control group included for comparison. The experiment involved monitoring the changes in earthworm weight and measuring their contraction rates to determine physiological responses. Statistical analysis revealed no significant differences in weight or activity between NaCl and CMA treatments for either species. However, higher concentrations of NaCl resulted in …

Elongate Locomotors Show Consistent Torque Patterns Across Substrates, Spencer Bradford, Henry Astley

Williams Honors College, Honors Research Projects

The four main movements found in snakes are understood mainly due to external study; however, muscular forces and resulting torques are poorly known. The main research objective is to study the torque production on different substrates using a snakebot. The study will give a rudimentary model for torque production on different substrates. It can then be compared against biological systems to understand snake movement at a muscular level. This study used a snakebot, allowing direct assessment of the current being run through each of its motors (proportional to torque). Data was then examined using a Principal Component Analysis test for …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia

Honors Program Theses and Research Projects

Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …

These species occur in the right-of-way (ROW) along several roads in Jefferson, Gage, Pawnee, and Richardson Counties which necessitates the need for added Environmental Review (ER) from Nebraska Department of Transportation (NDOT) staff and onsite surveys prior and during maintenance and construction to roadways. This project sought to minimize ER time, staff time, and increase the knowledge of these species in southeast Nebraska by:

1. Identifying precise locations of western massasauga brumation sites;
2. Mapping travel …

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand

2024 Fall Honors Capstone Projects - Archive

Anolis lizards are model organisms for studying natural selection and evolutionary processes. One trait that is hypothesized to be advantageous for males is head size, as larger heads lead to stronger bite forces and increased likelihood in outcompeting other males for mates. To better understand how linked head size and intraspecific competition are, the head morphology of male A. lineatopus was analyzed among Jamaican populations with varying levels of population density. Population densities were determined using standardized plot surveys and mark resight models. Head dimensions and body condition for individual lizards were measured at each site. My study found that …

The Impact Of Wild Pigs (Sus Scrofa) On Avian Occupancy And Vegetation Structure, Kenneth Wilson

Graduate Theses and Dissertations

Invasive species, particularly wild pigs (Sus scrofa), pose a significant threat to native ecosystems through both direct and indirect impacts. Wild pigs are large-bodied omnivorous species that can consume a wide variety of plants and animals and are known for destructive foraging behaviors, which likely threatens avian communities through habitat alteration and can impact the long term structure of ecosystems where they are present.

In chapter 1, we used a combination of avian point count surveys, vegetation assessments, and camera trap surveillance to quantify how the occupancy of breeding birds in bottomland hardwood forests changed in relation to …

Evolution Of The Human Eye: As Compared To Other Vertebrates, Madison Queener

Honors Projects

There are three different types of eyes, the simple eye, the compound eye, and the camera eye (Cambridge Dictionary) (Myer-Rochow, 2014) (UCL, 2020). The retina of the eye has evolved and adapted to fit the lifestyles of the respective organisms. Because of this part of the eye, organisms are able to see different colors and use light to define the world using photoreceptors. Photoreceptors are rod cells, which are light sensitive and process light, and cone cells, which perceive the different color wavelengths, that pass visual information to the brain (Kazilek, 2010). About 5% of the photoreceptors in the retinas …

Genome Editing Using Crispr-Cas9 In Annual Killifish Species, Keria Moritsugu-Vandehey

University Honors Theses

CRISPR-Cas9 genome editing has been used successfully to knock out genes in model organisms such as zebrafish, turquoise killifish, and cichlid fish. CRISPR-Cas9 genome editing has not been verified in the annual killifish, Austrofundulus limnaeus. We hypothesize that targeted editing of the tyrosinase gene in embryos of A. limnaeus will lead to fish without the ability to produce black pigment. Embryos at the 1-cell stage were injected with a Cas9 cocktail containing a mix of guide RNA molecules that target the genomic sequence of the tyrosinase gene and either an mRNA coding for the Cas9 protein or Cas9 protein. …

Physical Properties Of Odorants Affect Behavior Of Trained Detection Dogs During Close-Quarters Searches, Daniel Mejia, Lydia Burnett, Nicholas Hebdon, Peter Stevens, Alexis Shiber, Clay Cranston, Lauryn Degreeff, Lindsay D. Waldrop

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Trained detection dogs have a unique ability to find the sources of target odors in complex fluid environments. How dogs derive information about the source of an odor from an odor plume comprised of odorants with different physical properties, such as diffusivity, is currently unknown. Two volatile chemicals associated with explosive detection, ammonia (NH₃, derived from ammonium nitrate-based explosives) and 2-ethyl-1-hexanol (2E1H, associated with composition C4 plastic explosives) were used to ascertain the effects of the physical properties of odorants on the search behavior and motion of trained dogs. NH₃ has a diffusivity 3.6 times that of …

Theses, Dissertations and Capstones

Eastern diamondback rattlesnakes (Crotalus adamanteus; EDB) are an imperiled species native to the Southeastern United States longleaf pine (Pinus palustris) ecosystem. Several markrecapture methods have been used range-wide in hopes of increasing knowledge on their population numbers. I explored the efficacy of two mark-recapture methods (scale cauterization and dorsal head photography) using the Marine Corps Recruit Depot, Parris Island, SC EDB population in this multi-part study. The first method I evaluated was ventral scale branding, which has been widely implemented without knowledge of brand permanence. I classified misidentification errors at capture status (new versus recapture) and …

Osteohistological Assessment Of Edmontosaurus Radii From The Liscomb Bonebed, Prince Creek Formation, North Slope, Alaska, Emma Griffin

Student Research Poster Presentations 2024

Hadrosaurs were one of the most diverse dinosaur groups in the Late Cretaceous period and are known for their numerous articulated skeletons and monodominant bonebeds (Wosik et al., 2020). They are more commonly known as duck-billed dinosaurs and are found globally including latitudinal extremes such as the artic and Antarctica. Edmontosaurus, a genus of hadrosaur, are herbivores and are very large growing up to 8,000 pounds. Edmontosaurus were known to travel in herds as a defense mechanism and were one of the last non-avian dinosaurs living during the late Campanian stage through the end of the Maastrichtian stage, right up …

Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Estimating the probability of habitat use for a particular species is crucial to the direct management and conservation of that species. Without knowledge of habitat preferences, managers cannot effectively focus efforts on vital resources or landscape types. However, modelling probability of habitat use can be done in several ways which leaves room for variation and uncertainty in the estimates produced by each method. This study is an examination of the variation between two estimates of probability of habitat use while focusing on a particular subspecies of elk that inhabits a unique ecosystem relative to other elk subspecies. I modeled elk …

Compliance And Roughness In Relation To Gecko Locomotion, Brooklynn Campbell

Williams Honors College, Honors Research Projects

Geckos move efficiently through a variety of substrates, from swaying branches to wooden fences to the sides of structures. Previous studies have studied locomotion and adhesion on manmade and rough substrates; however, the work is limited when discussing locomotion and adhesion as a relationship of compliance and roughness. Ease of movement was quantified by speed, under the assumption that the faster a gecko moves, the easier it is for the gecko to cross the substrate. Gehyra oceanica geckos from Moorea, French Polynesia were tested on substrates varying in compliance and roughness with four different treatments in total. Compliance, roughness, and …

Impacts Of Disturbance And Nutrient Addition On Coastal Dune Arthropod Communities, Kayla Beitzel

Honors Theses

Coastal dune ecosystems are globally distributed ecosystems that occur from the tropics to the poles and serve as the first line of defense during storms. They are critical habitats for a variety of organisms and also play a critical role in stabilizing coastal habitats. These systems face increased pressure via urban development, recreational expansion, and sea-level rise (Newman et al. 2023; Webster et al. 2005). Insects are vital consumers in coastal ecosystems and act as regulators of plant growth. Low-diversity ecosystems, like coastal dune systems, often contain a higher abundance of low-diverse insect consumers (Ripple et al. 2021), which can …
