How Akron Affects The Water Quality Of The Cuyahoga River, Allyson Darst
How Akron Affects The Water Quality Of The Cuyahoga River, Allyson Darst
Williams Honors College, Honors Research Projects
The purpose of this study was to analyze whether the city of Akron had negative effects on the Cuyahoga river, and determine if the Cuyahoga River was naturally able to remediate these effects downstream. The pollutants measured in this study include hardness, bromine, residual chlorine, iron, copper, lead, nitrate, nitrite, ammonium chloride, total chlorine, fluoride, carbonate, pH, total alkalinity and cyanuric acid. This study was done using water testing strips (JNW Direct) to test the water at four different locations along the Cuyahoga River downstream (North) of Akron. This study found that the city of Akron does have a negative …
Uncovering A Natural History Mystery At The University Of Akron, Gary M. Holliday, Lara Roketenetz
Uncovering A Natural History Mystery At The University Of Akron, Gary M. Holliday, Lara Roketenetz
Proceedings from the Document Academy
Students were engaged in a combination of detective work, biology, archives, art, and education/outreach to prepare a collection of taxidermied birds donated to the University of Akron by the Rhodes family in the early 1900s for public access and exhibition. Students had the opportunity to learn from leading experts regarding the historical significance of biological collections, proper preservation protocols, digitizing and archival practices, and the urgency of science education and communication for a public audience. Many campus and community partners were involved, including experts from local museums and nature centers.

Determining Environmental Changes Using Time Lapse Photography, Emily Lemasters
Williams Honors College, Honors Research Projects
This paper aims to use photographs throughout several years to observe, examine, and make conclusions on changes occurring at different areas of the Bath Nature Preserve. Throughout the years 2013-2021, photographs have been captured at roughly the same angle at multiple locations in the preserve. These photographs will be placed into a time lapse video and examined to physically see how the environment is changing. Changes to the environment could be natural or as a result of outside factors. By examining these changes, it can be determined if alterations need to be made to help the environment thrive. Two specific …
Brown Booby Family Units: Comparing Mothers, Fathers, And Chicks Through Stable Isotopes, Erin Taylor
Brown Booby Family Units: Comparing Mothers, Fathers, And Chicks Through Stable Isotopes, Erin Taylor
Williams Honors College, Honors Research Projects
Seabird behavior and diet is important to study in order to determine where to focus conservation efforts in a rapidly changing climate. A primary aim of my project is to understand how brown booby family members from a breeding colony on Islas Marietas, Mexico relate to each other isotopically and in terms of their diet. Comparing the family units (mother, father, and chick from the same nest) of these seabirds and sex trends overall will help develop the big picture to determine the best conservation efforts for this species. I also aim to improve our ability to compare seabird plasma …
Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal
Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal
Williams Honors College, Honors Research Projects
Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.
Regional Patterns Of Vascularity Within The Limb Bones Of Small And Large-Bodied Bats, Logan Usher
Regional Patterns Of Vascularity Within The Limb Bones Of Small And Large-Bodied Bats, Logan Usher
Williams Honors College, Honors Research Projects
Bats have humeri and femora that are poorly vascularized or avascular compared to birds, with only larger bats typically displaying vascular canals. Vascular canals provide passageways for blood vessels and nerves, which help maintain bone homeostasis, and support bones by resisting torsional stresses placed on them. The presence of a greater number of canals in large bats suggests that they may have a larger need for the support of nutrient and waste exchange than their dense lacunar-canalicular system can provide on its own. The focus of the current project will be to analyze SR micro-CT data from various bat humeri …
The Effects Of Aqueous Nitrate On Freshwater Crayfish, Erik Hartman
The Effects Of Aqueous Nitrate On Freshwater Crayfish, Erik Hartman
Williams Honors College, Honors Research Projects
Globalization and a rising need for greater production from the agricultural system have increased the use of fertilizer by farms across the entire country. The purpose of this experiment was to observe the effects of aqueous nitrate (commonly found in many fertilizers) on the metabolic rate and hemolymph lactate concentration of freshwater crayfish. After exposure, there was no observed change in metabolic rate, but there was a significant decrease in hemolymph lactate concentration in the groups exposed to nitrate.
Evaluation Of The Signature Molecular Descriptor With Blosum62 And An All-Atom Description For Use In Sequence Alignment Of Proteins, Lindsay M. Aichinger
Evaluation Of The Signature Molecular Descriptor With Blosum62 And An All-Atom Description For Use In Sequence Alignment Of Proteins, Lindsay M. Aichinger
Williams Honors College, Honors Research Projects
This Honors Project focused on a few aspects of this topic. The second is comparing the molecular signature kernels to three of the BLOSUM matrices (30, 62, and 90) to test the accuracy of the mathematical model. The kernel matrix was manipulated in order to improve the relationship by focusing on side groups and also by changing how the structure was represented in the matrix by increasing the initial height distance from the central atom (Height 1 and Height 2 included).
There were multiple design constraints for this project. The first was the comparison with the BLOSUM matrices (30, 62, …
