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.

A Comparison of Winter Wildlife Use of Minimally, Moderately and Highly Impacted Shorelines on Lower St. Regis Lake and Black Pond in the Adirondack Park, NY

Wed, 05/09/2018 - 10:51
Abstract: Continued development and human interference with freshwater shorelines creates a degraded environment and can negatively affect native wildlife along impacted areas. Throughout the Adirondack Park, shorelines have experienced substantial degradation with the development of lakeside summer homes. There tends to be a strong preference for the aesthetics that lakes offer, as well as the numerous recreational opportunities they provide. The increased human use of shorelines and the development of anthropogenic structures has directly resulted in the degradation of shorelines in the Adirondack Park. Likewise, the Paul Smith’s College shoreline along Lower St. Regis Lake has been subjected to degradation throughout the history of the campus. This highly impacted site was selected, alongside minimally and moderately impacted sites in the surrounding areas as representatives for different impact levels. Shoreline degradation includes a decline in the health and presence of natural vegetation, creating a decrease in available food source for native wildlife. The removal of natural vegetation creates a decline in shoreline stability with the removal of root systems, allowing for greater amounts of erosion to occur. Additionally, degradation decreases available canopy cover and increases exposure of wildlife to predation. The objective of this study was to determine the difference in wildlife activity and diversity between three levels of shoreline impacts: minimal, moderate, and high. It was expected that the minimally and moderately impacted shoreline sites would show a greater diversity and abundance of wildlife than highly impacted shorelines. Trail camera data was analyzed at three sites for each treatment on Paul Smith’s College property, along both the Lower St. Regis Lake and Black Pond. Although we detected no significant differences in either activity or diversity across the treatments, there was higher relative activity and diversity in moderately impacted shorelines than minimally or highly impacted. However, wildlife species that are more rare and/or area-sensitive, such as the fisher (Martes pennanti) and American marten (Martes americana), were only detected in the minimally impacted shorelines of Black Pond. A restoration of the highly impacted shoreline to reflect minimally and non-impacted shorelines of the surrounding region would allow for opportunities to improve habitat for native wildlife species.

Effects of Silvicultural Treatments on Wildlife Communities at the Paul Smith's College Forest Research Demonstration Areas

Fri, 05/11/2018 - 16:15
Abstract: Logging has drastically altered North American forest ecosystems for centuries. While extensive studies have been done to determine the impacts of different silvicultural practices on plant communities, minimal research has evaluated the impacts on wildlife communities, particularly in the Adirondack Mountains. Silvicultural practices may significantly impact wildlife communities due to the disturbances it causes, as well as the way it alters the habitat. We monitored winter wildlife communities in the Forest Ecosystem Research Demonstration Area owned by Paul Smith’s College in the Northern Adirondack Park. By analyzing the data collected by trail cameras, tracks and measuring percent browse, we compared the abundance and diversity of wildlife in three silvicultural treatments (i.e., clearcut, group selection, control). We also collected data regarding the physical aspects of the silvicultural treatment plot (i.e. canopy cover and snow depth) to indicate the kind of available habitat. We found that despite there being the highest average relative activity in group selection, there is no significant relationship between average relative activity and harvest treatment type. Using the Shannon-Weiner Diversity Index, we found that the highest diversity was in control/reference. Due to our limited treatment sample size, we did not have conclusive findings in most areas of our study. However, the highest total tracks and relative activity were found in the clearcuts. We suggest that more research be done on this study in order to eventually make forest management plans that properly account for both plant and wildlife species.

Influence of Slope on Soil Organic Carbon on Costa Rican Coffee Farms.

Mon, 05/07/2018 - 10:21
Abstract: Soil management is an important factor on agroforestry farms that help with soil fertility and carbon storage. Coffee agroforestry farms in Central Valley Atenas, Costa Rica were analyzed between November 2008 and May 2017. The objective of this study was to see if there is a relationship between mean slope and annual soil organic carbon sequestration (Mg/ha), and mean slope and soil organic carbon storage (Mg/ha), from samples taken on November 2008/May 2009 and November2016/ May 2017. Sample were taken on five farms with twenty 0.05 ha plots. Many coffee farms in the central valley are assembled on steep slopes or sides of mountains. Steep slopes are susceptible to erosion affecting the amount of soil organic carbon sequestration and storage. There was not a significant relationship found between mean slope and loss of carbon sequestration annually in November 2016/ May 2017 (Mg/ha). Mean slope and soil organic carbon storage from November 2016/May 2017 were compared by testing the effects of slope with carbon storage and there was no relationship. Whereas a statistically significant positive relationship was found between mean slope and soil organic carbon storage from November 2008/ May 2009. Additional data was examined to look at annual carbon sequestration loss on conventional and organic farms. However there was not a significant difference between the two. When all farms were compared for their annual carbon sequestration loss, marginally significant difference was found, but reasons for these differences remain a hypothesis. Further research to examine these differences may include practices of the farmers and erosion steeper slopes before erosion implications were taken by the farmers.

Chocolate

Fri, 05/04/2018 - 15:03
Abstract: Chocolate is found everywhere but not usually thought about in savory dishes. Most people also do not think about what chocolate goes through to become a finished product. In my dinner, I showed how chocolate can be used in a four-course meal. My paper then goes through how cocoa is grown, the process, fair trade chocolate, health benefits, history, cocoa uses, and different kinds of chocolate.

Jenkins Mountain Backcountry Ski Glade

Wed, 05/09/2018 - 11:34
Abstract: The Paul Smith's College VIC is able to revitalize the ski glade on the back of Jenkins Mountain. The terrain was abandoned after a lack of interest, but now has opportunity to regain popularity. This study looks at land maintenance, risk management and marketing techniques to make the project successful. Putting these studies into action can benefit the VIC as well as the college, whether it's utilized for a students education or a visitors leisure. Bringing backcountry skiing to the property is a great addition to the many attractions provided by the land.

A Comparison of Macro-Invertebrate Communities in Different Substrates among Impacted and Minimally-Impacted Sites on Lower St. Regis Lake and Benchmark Sites on Black Pond

Wed, 05/03/2017 - 21:34
Abstract: Many shorelines today have been impacted by human activities which has resulted in changes in macro-aquatic invertebrate communities. Ecological restoration can be used in efforts to bring macro-aquatic invertebrates back into shorelines. However, data is needed to better understand how macro-aquatic invertebrates can be used in these efforts as indicator species to determine community structure health and function. This project compared the macro-aquatic invertebrate communities in impacted and minimally impacted sites located on Lower St. Regis Lake and benchmark sites located on Black Pond. The two objectives to this project were to 1) compare the species richness among impact levels and 2) compare the density among impact levels. Each impacted level has three sites and at each site ten samples were taken in a systematic way which resulted in 90 total samples. Samples were taken to the lab to be sorted and for macro-aquatic invertebrates could be identified to the family level. The macro-aquatic invertebrate community was different among each impact level. The overall family diversity was greater at the benchmark sites than the minimally impacted and impacted sites. Dominate substrate type that had a greater presence of different families were sites that had organic matter. The findings of this study create a more knowledge base which can be useful for future ecological restoration efforts on the impacted and minimally impacted areas located on Lower St. Regis Lake and to educate the public on the impacts on macro-aquatic invertebrates and their communities.
