Cultural eutrophication of Lower Saint Regis Lake using diatoms and organic content as indicators of eutrophication.
Tue, 04/28/2020 - 12:06
Abstract: Cultural eutrophication can greatly affect water quality, leading to algae blooms and can affect fish communities. Throughout the history of Paul Smith’s Hotel and College, development along Lower St. Regis lake has led to increases in eutrophic conditions, which has detrimental effects on water quality. In this study, a sediment core from Lower St. Regis Lake was analyzed to determine when past eutrophication events occurred. This was accomplished using species counts of diatoms from every 1.0 cm of sediment. The relative abundance of diatom species such as Tabellaria flocculosa, Asterionella formosa, and Fragilaria crotonensis were used as indicators of more eutrophic conditions. Loss on ignition (LOI) was also used to measure the organic content in the sediment at increments of 0.5 cm. The higher percent lost on ignition indicates higher productivity in the lake and more eutrophic conditions. Some samples from the sediment core were also dated using lead-210 to create a timeline that could be compared to known dates of events occurring along the lake that could have affected the trophic status of Lower St. Regis Lake. There was a sudden spike in the relative abundance of F. crotonensis and an increase in organic content at a depth of 20 cm in the core, indicating that conditions became more eutrophic. Based on the lead-210 dates, this spike in F. crotonensis and organic content occurred between 1898 and 1908, when development around the lake was increasing and Paul Smith’s Hotel added indoor plumbing with poor wastewater treatment practices.

A Resource Development Plan for incoming REALM and PACM students during Welcome Week at Alumni Campground through the PSC Guide Service
Fri, 05/15/2020 - 18:51
Abstract: For our Capstone, we are focusing on a feasibility and implementation plan regarding the Welcome Week Treks. We are proposing a four day, three night expedition utilizing the Alumni Campground located on Paul Smith’s Campus. The expedition will be called, “An Intro to the Adirondacks”. The Welcome Week treks will be open to the Recreation, Adventure Education, and Leisure Management (REALM) and Parks and Conservation Management (PACM) students and the expeditions will be run by the Paul Smith’s College Guide Service. During this expedition, students will be hiking, paddling, rock climbing, and utilizing the campus challenge course. The Paul Smith's College experience has been the turning point for many when deciding to attend this institution. From the beginning until the end, Paul Smith’s College strives to give the best experiential learning to their students, and give them the best possible learning experience to give their students the brightest future.

RAELM and PACM Program Analysis: Does the Online Presence Match the Experience?
Thu, 05/14/2020 - 10:52
Abstract: This is a research-based project that analyzes the Recreation, Adventure Education, and Leisure Management (RAELM) and Parks and Conservation Management (PACM) programs at Paul Smith’s College. The purpose of this research is to determine if there is a gap between the current advertised representation of the RAELM and PACM programs on the official Paul Smith’s College website and social media, and the experiences that current students within these programs have. The research includes an analysis of the programs’ current representation on the Paul Smith’s College website and social media, data collected from interviewing faculty involved in the program and surveying current students, and a literature synthesis of similar research projects and academic curriculums.

What Are the Differences in Trichome Density and Morphology Between Arabidopsis Lyrata Subsp. Lyrata Populations When Grown in A Northern Common Garden, Outside of Their Geographic Distribution?
Tue, 04/30/2019 - 15:23
Abstract: Trichomes are diverse among plants. There is evidence suggesting that environmental factors may influence these structures and their densities. Other evidence shows that weather may influence genetics and gene expression. Arabidopsis lyrata subsp. lyrata is a wild flower that is native to North America and Europe and has been extensively studied. Literature regarding Arabidopsis states that within the family and genus, there is evidence suggesting that trichomes can be either non-branched, twice branched or thrice branched. This study’s purpose was to analyze how trichome density, and morphology in Arabidopsis lyrata subsp. lyrata differs between populations when grown outside of the natural distribution limit. Four populations of Arabidopsis lyrata subsp. lyrata were studied based on latitude. After analyzing the outcomes, unexpectedly there are no major differences between the north and south populations; however, there are differences between the four populations. Based on the data gathered, it was determined that the population, North2 (07G) must be genetically different from the other three populations. The four populations were grown together in a common garden; thus, all variables were the same. The environment did not influence trichome density or morphology within the North2 population, therefore the structures were genetically pre-determined.

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.
