No Known Antidote: Quantification of a deadly toxin, tetrodotoxin, in red efts (Notopthalamus viridescens; Rafinesgue, 1820)
Mon, 04/29/2013 - 17:42
Abstract: Tetrodotoxin (TTX) in found in taxa worldwide including the eft life stage of the eastern newt (Notopthalamus virisdescens). Previous studies have shown that there is variability of TTX concentrations within efts and newts, and it is not known if the presence of TTX in these efts is common among populations. Our objective was to determine the distribution of TTX within the body N. viridescens efts. We hypothesized that the skin would have the highest concentrations of TTX as it is the area of the body that will likely come into contact with a predator. If certain regions of the skin come into contact with a predator more often than others, there may be significant differences in the dorsal, abdominal and pectoral regions of skin. Further, we hypothesized that the ova would have the second highest concentration of TTX as they are vital to reproduction yet vulnerable to predation. Through HPLC analysis we determined the concentrations of TTX within different tissues of N. viridescens efts including the: dorsal, pectoral, and abdominal skin; ovaries; testes; liver; pancreas; and alimentary canal. The concentrations of TTX between the different tissue types are not significantly different, nor were individuals significantly different in concentration of TTX from one another. Toxicity levels were high in comparison to other N. viridescens efts and more similar to the toxicity of highly toxic Taricha newts. The high toxicity of N. viridescens could be contributed to strong predation pressure by the slightly resistant garter snake (Thamnopsis sirtalis) and eastern hognose snake (Heterodon platirhinos).

Paul Smith's Car Sharing Program: A feasibility study of implementing a car-sharing program at Paul Smiths
Mon, 04/22/2013 - 16:21
Abstract: Car-sharing is a program in which companies own a fleet of vehicles, insure them, maintain them, and offer memberships to people who wish to use them. Car-sharing is an eco-friendly way to use a vehicle when needed without the need to own one. These programs are environmentally friendly as well as cost effective. Paul Smith’s college is an environmentally friendly campus currently lacking an effective program to reduce emissions on campus. In addition to the absence of an efficient program to reduce emissions, Paul Smith’s College is experiencing a shortage of parking spots due to the excessive number of vehicles parked here. In effort to take further steps towards being an environmentally friendly campus and reduce the number of vehicles parked on campus, a feasibility study to implement a car-sharing program on Paul Smith’s College campus will be conducted.

Conveyor Belt Sushi Restaurants: A study of customer knowledge and perceived benefit of technological management systems within conveyor belt sushi restaurants
Mon, 04/22/2013 - 15:42
Abstract: Radio frequency identification management systems are used by conveyor belt sushi restaurants to ensure the freshness of sushi they provide to customers. The workers within these restaurants feel the systems improve business but whether the customers, who are imperative in a restaurant’s success, are aware of them and what benefits they perceive is still undefined. The purpose of this study is to determine how and to what extent the knowledge and perceived benefits of RFID systems in conveyor belt restaurants affect customer satisfaction. This qualitative study focuses on the relationship between technological management systems and customer satisfaction as it pertains to freshness. A method of voluntary surveys will be used in this study to measure the knowledge and perceived benefits from frequent sushi consumers dining within a conveyor belt sushi restaurant, as well as online using social media sites. The survey results will be compiled and used to determine the percentage of consumers who are aware of these systems, whether they believe they are beneficial and how satisfied they feel knowing the restaurant uses it. This study will assist sushi restaurant owners in understanding how their customers perceive these systems and potentially furthering their business.

Monitoring the Zebra Mussel Invasion Front: Use of New Technology
Thu, 02/09/2012 - 15:39
Abstract: Zebra mussels are invasive mollusks that are affecting the well-being of the water bodies in the United States. This study uses environmental DNA (eDNA) is a sensitive early detection system that may be useful in monitoring their spread. The purpose of this study is to determine the effectiveness of eDNA technology in identifying infested water bodies, to determine if zebra mussel DNA is in the Adirondack water bodies not known to be infested, if the water chemistry of these water bodies is favorable for zebra mussel establishment, and if the eDNA technology is transferable to an institution like Paul Smith’s College. Eighteen lakes, all in New York State were sampled, fifteen of which are located in the Adirondack Park. DNA was extracted from water and plankton samples and species specific primers were used for PCR amplification to determine if zebra mussel DNA was present. Of seven samples taken from sites known to be infested, five of these tested positive for zebra mussel eDNA. Four lakes not known to be infested within the Park also tested positive for zebra mussel eDNA. Based on zebra mussel risk parameters (water chemistry) applied to 1,469 Adirondack water bodies, less than 3% are at risk of zebra mussel establishment. However it is possible that established populations could occur at microsites that may have locally high levels of calcium and higher pH.
