A Paleolimnological study of precipitation variability in the Adirondacks over the last thousand years

Mon, 12/02/2013 - 20:40
Abstract: At present, most regional climate models anticipate wetter conditions by the end of this century, but a few models anticipate drier conditions. This study uses foresight to test these models, as well as describe the relationship between the dominant climate system in the region and past precipitation in the Adirondacks. Precipitation was inferred from diatom assemblages observed along a lake sediment core extending into the 1000 years. This study shows that abrupt, extreme wet events were common during the last 1000 years, and a relationship between the dominant climate system (North Atlantic Oscillation) and precipitation was irregular during the cool Little Ice Age but negatively associated during the warm Medieval Climate Anomaly. With temperatures in the Northeast projected to increase by 2-5 degrees C by 2100 AD, our study suggests the region may become more arid rather than wetter, opposite of what models currently suggest.

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.

Evaluating the Recovery of Lakes from Acid Deposition in the Adirondack Park

Mon, 12/02/2013 - 22:49
Abstract: Acid rain has been an environmental problem since the 1980’s and has been a core issue in the Adirondack Park located in the northern part of New York State. Acid rain is created by acidic gases from anthropogenic uses that mix in the atmosphere with precipitation and forms acid deposition. Acid Rain lowers the pH of water which has detrimental effects on the biota living within lakes. There is a general consensus that the chemistry of lake water is recovering from acid deposition, however, there have not been sufficient studies on the state of recovery from acid rain in the Adirondack Park or much of the United States. This study will investigate if lake recovery is indeed happening in the Adirondack Park. This study analyzed the water chemistry of lakes using data collected from the Adirondack Lake Survey Corporation (ALSC) and New York State Department of Conservation (DEC). The object of this study is to find a trend in the water chemistry and combine it with DEC data to evaluate the present condition of lakes within the park. The results showed that there are not significant correlations of the data besides SO42- concentrations, which have been approving in the park in the last 20 years.

Alternative Management Methods for Acid Deposition in Lakes

Fri, 04/26/2013 - 18:09
Abstract: Acid deposition has been causing the acidification of lakes in the Northeast United States for decades. The result is lake ecosystems with abnormally low pH that stresses the organisms that live there. Management plans in place in the Adirondack Park have been working to remediate acidified lakes for the past few decades. Limestone (CaCO3) has been the generally accepted method for managing these lakes, in an attempt restore the lakes pre-impacted conditions. The purpose of this study was to evaluate the effectiveness of liming in reversing the effects of acidification, and to identify effective alternatives. Five alternatives were tested against limestone: Sodium carbonate (Na2CO3), Sodium bicarbonate (NaHCO3), Sodium acetate (CH3COONa), Magnesium carbonate (MgCO3), and Potassium carbonate (K2CO3). Double End-Point Titration tests were performed on all of the compounds, using both distilled water and lake water, to determine the relative alkalinity of each compound. Alkalinity is the measure of the ability of a solution to neutralize acid, also known as its "buffering capacity." Lake water was used in the titration tests in an attempt to mimic in-situ testing. The results of the titrations showed limestone proving to be the most effective in the lake water tests, with Magnesium carbonate and Potassium carbonate ranked closely behind. While limestone has proven to be an effective management method, its reliability is dependent upon the characteristics of the lake catchment, making it important to continue to look for alternative solutions.

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.

Where in the Unite States Can Dual-Flush Toilets Flush Out Savings?

Mon, 12/02/2013 - 13:06
Abstract: Potable water is becoming increasingly scarce in water poor regions of the United States. Reducing the volume of potable water consumed residentially and commercially is vital to ensure a stable water dependent future. Converting a traditional single-flush toilet into a dual-flush toilet is arguably the most effective means for reducing wastewater production in both residential and commercial settings. The objective of this study was to determine where within the United States dual-flush retrofits are cost effective. A cost-benefit analysis illustrating the price of the dual-flush retrofits & the monetary value of the water conserved post installation will be created using Paul Smith’s College campus of northern New York State as a testing site. The study will utilize a total of 145 toilets for both commercial and residential settings. Costs of the installation and purchasing of the product will be used to determine pay-back period and thus, the economic benefit of installing dual-flush toilets. Secondary data from previously completed dual-flush studies determined where within the 50 states dual-flush retrofits are cost effective. The resulting data illustrated relatively long payback periods for the greater United States with the most dramatic differences being seen in Hawaii and the least in Nebraska.

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.

Promoting Conservation of Biodiversity in the Adirondack Park Through Understanding and Engaging Stakeholders

Thu, 02/09/2012 - 11:31
Abstract: Anthropogenic disturbance of natural environments has led to the widespread loss of native biodiversity and degradation of ecosystems. It is increasingly recognized that addressing this “biodiversity crisis” entails understanding the societal drivers of unsustainable patterns of use. Conservation psychology is a new discipline that specifically focuses on understanding the linkages between human behavior and action and promoting a healthy and sustainable relationship between humans and nature. In this project, we employed principles of conservation psychology with the goal of improving the efficacy and efficiency of conservation of biodiversity in the Adirondack Park (AP). To meet this goal we employed three specific strategies. The first of these strategies was the use of surveys to assess the values, attitudes, and actions different stakeholders have in regards to conservation of biodiversity in the AP. These surveys were disseminated via both direct mailings and online, and included 30 questions. Our second strategy was to use discourse analysis to create a dictionary of terms and phrases employed in a positive, neutral, and negative light in regard to conservation of biodiversity. This entailed analysis of 30 emic accounts derived from opinion articles written by stakeholders in the AP, as well as analysis of a number of etic accounts drawn from online sources. Our third strategy was to use conservation psychology literature to assess ways in which the presentation of information and peer-dynamics influenced the responses of stakeholders towards conservation of biodiversity. Using the combination of these three strategies, we were able to provide a holistic understanding of how different stakeholders in the AP perceive and act towards biodiversity conservation; identify language that can be used to illicit a more positive response from these stakeholders; and identify specific tools based on principles of psychology that can encourage more active and effective engagement in conservation of biodiversity by different stakeholders. Our research findings will allow groups focusing on promoting conservation of biodiversity in the AP to be more effective and efficient in their work in the future.

Refining Karner blue butterfly (Lycaeides melissa samuelis) restoration efforts by comparing captive rearing and release methods used in the Albany Pine Bush

Mon, 12/05/2011 - 18:36
Abstract: With this research, the release efforts of the endangered Karner blue butterfly (Lycaeides melissa samuelis) of the Albany Pine Bush (APB) in New York State at two different stages of the butterfly’s life cycle were compared. Survival success rates were determined and environmental factors were measured to assess captive rearing methods and improve restoration efforts in the APB Preserve. Captive rearing efforts have been used in the past in this area, releasing Karner blue butterfly pupae into the wild; however, this year in 2011, pupae were allowed to eclose from their chrysalides in the lab and were released into the wild as adult butterflies. The analysis of the information gathered showed that the release of Karner blue butterflies in the adult stage offered a greater survival rate over release in the pupal stage. The average daily maximum temperatures increased each year during the summers of 2009-2011. Information from this research is important to help prevent the extirpation of this species from the Albany Pine Bush Recovery Unit and may be helpful to organizations such as the US Fish and Wildlife Services and the Nature Conservancy.
