The James Bradford Colloquium

Monday, April 16th - 7:00 p.m., BSC 343 & 336

The James Bradford Colloquium is a presentation of senior research from the biology, chemistry, geology, physics, mathematics, computer science & psychology departments as well as interdisciplinary programs in molecular biology, environmental science, neuroscience, and conservation science.


7:00 BSC 343 Opening Remarks: Jim Dooley


Session I
Chair: Dr. Jim Dooley

BSC 336 7:15 p.m.  Geology:  Jason Esselburn – “Ostracodes As Indicators of Hydrochemistry At a Reclaimed Surface Mine, The Wilds, Southeastern Ohio.”

Since 2005, an ongoing survey of the ostracode species in certain lakes and streams at The Wilds has indicated a trend with respect to water quality (specifically solute composition, pH, and total dissolved solids).  This study investigates both the ostracodes’ hydrochemical preferences and the trends in surface water quality as a result of the sequential reclamation of the surface mine that is now The Wilds.

BSC 336 7:30 p.m.  Neuroscience:  Margot Kossmann – “Causal Relationships Between Serotonin and Eating Behavior in Rats: Implications in Eating Disorders.”

Along with genetic vulnerability, serotonin imbalances are likely responsible for the symptoms of anorexia, bulimia, and binge eating. Animal models were developed to support this theory.  Serotonin levels were found to correlate negatively with food consumption, suggesting that increased serotonin and serotonin turnover could be responsible for the symptoms of anorexia.

BSC 336 7:45 p.m.  Biology:  Elizabeth Sickler – “The Effect of Plant Oils and Extracts on the Growth of Staphylococcus aureus and Methicillin Resistant S. aureus (MRSA).”

In this study, antimicrobial susceptibility test methods such as the Agar Disk Diffusion method, Microatmosphere test, and the Tube Dilution test were used to determine the effects of plant oils, plant extracts, and colloidal solutions on the growth of Staphylococcus aureus and a methicillin-resistant strain of S. aureus.

Session II
Chair: Dr. Danny Ingold

BSC 343 7:15 p.m.  Conservation Science:  Amos Ludwig – “Studying and Mapping Potential Habitat Composition for Wood Frogs (Raana sylvatica) at The Wilds”

The objective of this study was to survey and characterize potential wood frog (Rana sylvatica) habitats at the Wilds.  Wood frog terrestrial and aquatic habitats were assessed based on factors described in the literature as significant in influencing survivorship and reproductive success.  The significant factors included canopy cover, soil saturation, availability of debris for over-wintering, buffer distance to breeding habitat, pool depth and area, absence of fish, branches for oviposition, pH and absence of toxic metals.  Results suggest a limited amount of suitable habitat may be available at the Wilds


BSC 343 7:30 p.m.  Psychology:  Jessica Shipe “Motivational Influences on Motor Learning in Children”

Research has shown that children and adults alike use many different types of motivational processes to work through tasks.  The goal of the present research was to define different types of motivation and recognize these types of motivation in children within an experimental setting.  The results of such work may be utilized to further understand which motivators are prevalent in children and which of them could be increased in order to help a child become more devoted to his or her tasks.

BSC 343 7:45 p.m.    Chemistry:  Lopa Paul – “Preparation and Behavioral Evaluation of Novel Analogues of Methylphenidate Hydrochloride”

The study explored methods to synthesize analogues of methylphenidate hydrochloride (Ritalin), a mild central nervous system stimulant, used in the treatment of >attention-deficit hyperactivity disorder (ADHD). The objective is to determine how the structural modifications of the drug will affect its binding affinity to the receptor site, dopamine transporter (DAT), and thereby affect behavioral expressions.
