A Guide To Helminth Parasites Reported From Shorebirds (Charadriidae) From The Americas, Albert G. Canaris, Sofia Capasso, Gay J. Canaris
A Guide To Helminth Parasites Reported From Shorebirds (Charadriidae) From The Americas, Albert G. Canaris, Sofia Capasso, Gay J. Canaris
MANTER: Journal of Parasite Biodiversity
The shorebird family Charadriidae in the Americas consists of 21 native and 7 vagrant species. Members of the family occupy a diversity of open habitats, ranging from Arctic tundra during nesting, coastal sands, and mudflats to inland prairies, savannas, and wetlands. Some native plovers migrate from nesting grounds in North America to wintering grounds in South America (Hayman et al., 1986; Paulson, 2005; Winkler et al., 2020). Our search of the literature revealed the following: 17 of 28 host species infected with helminth parasites, 153 helminth species, and 199 infections involving 13 geographic areas. The purpose of this guide is …
Blue Jay Call Profile In Disparate Environments, Daniel A. Gesualdi
Blue Jay Call Profile In Disparate Environments, Daniel A. Gesualdi
Pell Scholars and Senior Theses
Many species of birds have been observed to develop higher-pitched calls in urban environments; however local Blue Jays are unstudied (Mockford and Marshall, 2009). The urban environment's high noise pollution imposes a significant fitness challenge; then, the urban Jay calls will be different (higher) than rural Jay(Parris and Schneider, 2009). A series of recordings were taken in rural and urban environments; it was clear that there is a significant increase in maximum and minimum kHz in urban jays than rural jays. These results suggest that blue jays alter their calls to accommodate the environmental factors in urban settings similar to …

A High-Androgen Microenvironment Inhibits Granulosa Cell Proliferation And Alters Cell Identity, Renee Mcfee Fee, Sarah Romereim, Alexandria P. Snider, Adam F. Summers, William E. Pohlmeier, Scott G. Kurz, Robert A. Cushman, John S. Davis, Jennifer R. Wood, Andrea S. Cupp
Department of Animal Science: Faculty Publications
A naturally occurring bovine model with excess follicular fluid androstenedione (High A4), reduced fertility, and polycystic ovary syndrome (PCOS)-like characteristics has been identified. We hypothesized High A4 granulosa cells (GCs) would exhibit altered cell proliferation and/or steroidogenesis. Microarrays of Control and High A4 GCs combined with Ingenuity Pathway Analysis indicated that High A4 GCs had cell cycle inhibition and increased expression of microRNAs that inhibit cell cycle genes. Granulosa cell culture confirmed that A4 treatment decreased GC proliferation, increased anti-Müllerian hormone, and increased mRNA for CTNNBIP1. Increased CTNNBIP1 prevents CTNNB1 from interacting with members of the WNT signaling pathway thereby …

Connecting Environment And Phenotype: Deciphering Mechanisms Of Diapause Entry And Exit In The Annual Killifish Austrofundulus Limnaeus, Erin Monica Davis
Connecting Environment And Phenotype: Deciphering Mechanisms Of Diapause Entry And Exit In The Annual Killifish Austrofundulus Limnaeus, Erin Monica Davis
Dissertations and Theses
Embryonic development is complex, dynamic, and dependent on environmental factors. Mechanisms of sensing and integrating environmental stimuli are diverse, and understanding these mechanisms in extant species can elucidate how complex phenotypes emerge from genomic information expressed in an environmental context. In Austrofundulus limnaeus, an annual killifish with alternative developmental trajectories, light and temperature are vital factors that determine if an embryo will enter a state of diapause. We hypothesize that embryos of A. limnaeus use the vitamin D3 signaling pathway as a vehicle to incorporate these ecological signals into their developmental programing. Here we provide evidence of …

Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo
Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo
Campus Research Month
Harvester ants have an interesting behavior of bone collecting. Therefore, harvester ant nests that are positioned around the fossil sites contain various fossil fragments. If there is a statistically significant correlation between the abundance of fossil fragments and the distance of the ant nests from the main fossil sites, ant nests can potentially be used to predict the proximity of the main fossil sites.
Detecting Dna Oxidation In Sperm, Alexie Zwerdling
Detecting Dna Oxidation In Sperm, Alexie Zwerdling
Student Research Symposium
Declining body-wide levels of nicotinamide adenine dinucleotide (NAD) that are present in normal aging men are linked to decreased sperm quality and DNA integrity. When NAD is low, the amount of oxidative stress on the DNA appears to be increased, due to the limited regeneration of the antioxidant glutathione, which is NAD-dependent. We therefore hypothesize that the increased sperm DNA damage in the aging male is caused by an elevated formation of 8-oxoguanine in the DNA, caused by increased oxidative stress when NAD levels are low. To test this hypothesis, a transgenic mouse model (ANDY mouse) was used to create …
Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman
Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman
Honors Thesis
Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …
Using Handmade Cloning To Reduce Oocyte Mitochondria In Reconstructed Embryos, Laura Adams
Using Handmade Cloning To Reduce Oocyte Mitochondria In Reconstructed Embryos, Laura Adams
Student Research Symposium
Mitochondrial heteroplasmy, the presence of more than one population of mitochondrial DNA (mtDNA) in one cell, can cause metabolic issues and reduced ATP synthesis, even at relatively low levels. The presence of this condition in somatic cell nuclear transfer (SCNT) embryos likely contributes to reduced prenatal and postnatal viability: the majority of the oocyte’s mitochondria is still present at the time of nuclear transfer, as well as through any further embryonic development post-fusion and activation. Though the somatic cell also contributes its mitochondria (which can successfully communicate with its nucleus), the oocyte’s mitochondria compose a greater proportion of the total …

Investigating The Primary Production Of Bear Lake's Filamentous Algal Blooms, Maycee Page
Student Research Symposium
Filamentous algae blooms(FABs) have been appearing on the Western Shore of Bear Lake within the last couple of years with minimal research done on them. Through YSI meter sampling of light and dark trials of Bear Lake’s Eastern and Western shores and Fluorometer analysis of samples of filamentous algae taken from each site, gross primary production(GPP), net ecosystem production(NEP), and community respiration were calculated. Through graphical analysis between many of the factors that were accounted for, one statistical significance found was between the mass in milligrams of periphyton produced and the gross primary production. The two have a negative correlation …
Roles Of Nad+ In Testicular Aging And Epigenetic Sperm Modifications, Renata Hoskova
Roles Of Nad+ In Testicular Aging And Epigenetic Sperm Modifications, Renata Hoskova
Student Research Symposium
Since 1980, the average age of first-time fathers has been increasing. With increased age, sperm chromatin quality and nicotinamide adenine dinucleotide (NAD) levels are reduced. In order to condense around protamines, sperm DNA undergoes breaks, at which time epigenetic reprogramming occurs. In humans, about 2% of DNA stays wound to histones in spermatozoa. Histones carry post-translational modifications that control gene activity and have the potential to transmit epigenetic information to the offspring. Analysis of epigenetic sperm modifications is being conducted within niacin deficient versus niacin replete mice. The experimental plan includes the characterization of histone exchange in elongating spermatids via …
Fecal Microbiota Transfer (Fmt) From Tumor-Bearing Mice Fed The Total Western Diet (Twd) Does Not Contribute To A Higher Tumor Burden In Mice Fed A Healthy Diet, Porter Green
Student Research Symposium
Colorectal cancer (CRC) is the third most common cause of cancer death in the United States. Diet and gut microbiome have shown to influence the development of colitis associated colorectal cancer (CAC). For this study, the goal was to determine the association between colon inflammation, diet and microbiome in the development of CAC in mice. The primary objective of this study was to determine the contribution of gut microbiota from mice donors who have previously consumed one of two basal diets: 1) the standard AIN93G diet, which is designed to promote rodent health; and 2) the total Western diet (TWD), …
Roles Of Nad In Dna Repair And Response To Oxidative Stress, Micah Forbush
Roles Of Nad In Dna Repair And Response To Oxidative Stress, Micah Forbush
Student Research Symposium
It has become a common trend for people to start their families at a later age, often due to lifestyle choices like achieving career goals first and waiting to achieve financial stability. Along with this trend of increasing parental age comes another, the decrease in fertility. While it is well established that female fertility declines significantly with age, current research is showing that male fertility may be impacted just as much. NAD (Nicotinamide Adenine Dinucleotide) is an important biochemical cofactor in most metabolic reactions, and importantly, is it also essential for DNA repair. As age increases in humans, the amount …

Bolstering Southeast Asia's Livestock Biosecurity And Climate Change Resilience Essential For Global Health, Madelyn Kunzler
Student Research Symposium
A large factor of climate change is its effect on infectious zoonotic diseases. Zoonotic diseases are diseases that can be transferred from animals into humans. Cases of zoonotic diseases have increased as humans have interacted more with animals, and as worldwide travel has become more frequent. It is predicted that 60% of emerging human diseases will be zoonotic. The cases will continue to increase to due climate change. As climate change continues, research has shown that new diseases will emerge from the melting permafrost and ice caps. It is also likely that pre-existing diseases will be able to migrate to …

Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos
Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos
English Department: Research for Change - Wicked Problems in Our World
The whitetail deer is a key species for Pennsylvania’s forests, but their ecological balance has been disturbed by unregulated growth and urban sprawl. The deer population in Pennsylvania has exploded since the 1880’s causing a wide range of damage on the ecosystem, and humans. To reduce deer populations to sustainable levels, the Pennsylvania Game Commission relies heavily on hunters to dedicate time in the fall to go out and fill the tags the they issue. Hunter participation all around the world is decreasing for a variety of reasons. Fewer hunters out in the field causes revenue losses for the Game …

United States Department of Agriculture Wildlife Services: Staff Publications
Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scent-trailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic and applied biological tools. However, pinpointing behaviors dominantly driven by chemical cues versus other competing environmental cues can be challenging. Y-mazes are common tools used in animal behavior research that allow quantification of vertebrate chemosensory behavior across a range of taxa. By reducing external stimuli, Y-mazes remove confounding factors and …

Proper labeling of seafood is important to prevent economic deception and protect public health. The goal of this research was to investigate prepackaged frozen fish for Country of Origin Labeling (COOL) compliance, species labeling, net weights/short weighting, and percent glaze. A total of 111 frozen prepackaged fish fillets were purchased from grocery stores in Southern California (USA). Samples were designated as COOL compliant if they displayed both procurement method and country of origin in accordance with COOL requirements. Species labeling was examined by comparing the species identified with DNA barcoding to the acceptable market names provided in the FDA Seafood …
