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.

Proposal for Improvements to Alumni Campground Waterfront
Sat, 12/14/2019 - 15:42
Abstract: The Alumni Campground is full of potential. A front country campground in close proximity to many great wilderness experiences. Some of those experiences can be best reached by water and yet the Alumni Campground waterfront is not much more than a single “No Swimming” sign nailed to a tree. This lack of infrastructure has caused degradation of the shoreline as the user base for water craft does use the campground as a starting point for excursions onto the St. Regis waterways but due to a lack of durable launching sites they have created several eroded and denuded spots along the lakes bank. In order to accommodate the amount of use this asset receives and prevent further degradation this proposal is designed to give the Alumni Campground Committee a sensible set of options for structural improvements designed to suit the user bases needs and protect the valuable waterfront resources.

Reinvigoration of the Champlain-Adirondack Biosphere Reserve: Stakeholder Perceptions
Tue, 05/08/2018 - 15:02
Abstract: The Champlain-Adirondack Biosphere Reserve (CABR) was designated by the United Nations in 1989. This reserve spans the entire Adirondack Park, and includes the Lake Champlain Valley in Vermont as well. Biosphere reserves focus on conservation at a global level, and use international knowledge from lessons learned to best benefit each specific biosphere. Although CABR was designated in 1989, it became classified as inactive soon after. In 2016, Brian Houseal, Director of SUNY's College of Environmental Science and Forestry Newcomb Campus, prepared a periodic report to UNESCO on CABRs current status. The goal of this research was to determine the probability of stakeholder support to bring CABR out of inactivity, almost 20 years after it was designated originally. The research performed focused on stakeholders’ awareness and perceptions of the CABR, along with past indications of concerns and resistance among local residents. The research addresses this deficit and identifies and clarifies our representative’s samples perceptions of the designation. The research revealed that land use rights were still the major concern. The research revealed that this was still a concern because there is still a major lack of information on the CABR land classifications/land use rights. Information on CABR was concluded to be one of the largest challenges at this time. This research revealed that 68% of the residents were unaware of CABR until the periodic review was published in 2016, and over 40% of the residents had no idea what CABR was until they received an invite to come to the focus group.

Lower St. Regis Lake Survey: A Comparative Study of Fish Population Structure and Function over Time
Thu, 12/13/2018 - 14:24
Abstract: Lake surveys are performed on bodies of water to provide a health analysis of fish populations over time. Lake surveys can be conducted in a variety of ways to attain specific data. Lower St. Regis Lake was surveyed to determine the fish community composition and to understand fish population traits. Using fyke nets placed at six predetermined locations for 24 hours, as well as fishing, we collected data for age, length (mm), weight (g), and parasites present. Data was analyzed in the lab using Excel to form graphs and tables to demonstrate our findings. Catch rates were lower compared to years before and comparing our data to New York State Department of Conservation data found that our length-at-age data was lower for the six-species sampled. Pumpkinseed and yellow perch were the only two species to have over twenty fish sampled. Decreased air temperatures brought in by a cold front during the week of our sampling may have been a reason for our lower number of fish caught. Mesh size is also a bias while using these nets as smaller fish can escape, and predatory fish can prey on smaller fish while in the net. Some species of fish such as black crappie may be more susceptible to capture due to its habit of associating with structure.

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.

Vista Wellness: An Educational Community Center for the Glenview Preserve
Fri, 12/14/2018 - 23:29
Abstract: The Glenview Preserve is home to a beautiful open vista of the High Peaks. This land was recently purchased by the Adirondack Land Trust and is looking for ways to sustainably manage the property by utilizing Paul Smith’s College capstone students for recommendations. One viable opportunity the ALT can incorporate, is the addition of a sustainable forum and conference center. With a community-oriented mind, Vista Wellness will provide a multitude of spaces for businesses and individuals to retreat while partaking in recreational activities. Vista Wellness is designed to be low impact with features such as a living roof and LEED certification. Using a promotional commercial and an intricate model, using state of the art construction supplies, we are able to convey the need for this addition to the Glenview property.

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.

Engaging Visitors Of Glenview Preserve With Interpretive Signage
Fri, 12/14/2018 - 11:42
Abstract: Glenview Preserve is a Lowland forest and Field property that boarders the Bloomingdale Bog. Implementing an educational system at the preserve would lead to more public interaction that would guarantee support for the Adirondack Land Trust’s mission objectives. This approach would involve the development of an interpretive day-use site, interpretive programs and signs, and an outdoor education space. For my portion I will be investigating how the Adirondack Land Trust can construct interpretive signage that is weather resistant and provides valuable content. The quality of the content will be evaluated using the National Association of Interpretation principles of POETRY. These signs will promote ALT’s mission objectives by encouraging people to make a difference after their visit through well-constructed and entertaining information. Visitors will donate money to ensure that having an educational system at the preserve is a leading concern of the Adirondack Land Trust’s management plan for Glenview Preserve.

Homesteading for Beginners
Wed, 12/12/2018 - 14:51
Abstract: Homesteading isn’t just a movement, it’s a way of life. Our first research proposal was to create a guide to homesteading for beginners. Initial research showed there are countless types of homesteads and so we decided to research what homesteading is and the different ways you can homestead. Homesteading can be defined as a life of self sufficiency. But our research found that there can be many ways to achieve that goal.
