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.

Planning and Future Management of the Adirondack Land Trust Glenview Preserve

Sat, 05/11/2019 - 08:51
Abstract: The Adirondack Land Trust purchased a 238 acre parcel of land, Glenview Preserve, from the Trevor family in 2016. The Glenview Preserve is located along New York State Route 86 in Harrietstown. The Glenview Preserve already consists of a heavily visited scenic vista of Whiteface Mountain, the McKenzie Range, and other Adirondack High Peaks. The property borders the Bloomingdale Bog, the third largest boreal peatland in New York State. The Glenview Preserve can be a perfect spot to incorporate a trail system to allow visitors the opportunity for non-consumptive recreational activities. When creating a trail system for recreation it is important to examine the impacts on local flora and fauna. A clearly designated trail system is the number one way to mitigate impacts on soil, vegetation, wildlife, and water created by visitors. Within the preserve interpretive signs will be implemented to educate and inform visitors on proper usage of the trail system. The unique thing with the area is the gradual grade of only 50 feet so the breathtaking views are virtually accessible to everyone who visits. Recreational activities allow people to get outside and enjoy nature and hopefully build personal environmental stewardship. The trail system will not only allow recreational opportunities for visitors but establish a sense of an outdoor community.

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.

A Comparison of Terrestrial Invertebrate Communities among Impacted, Minimally Impacted, and Reference Sites: Implications for Shoreline Vegetation Restoration

Fri, 12/14/2018 - 12:19
Abstract: The problem that this study attempts to address is the possibility of terrestrial invertebrate communities being negatively impacted by man-made disturbances along shorelines. This is a relevant issue because terrestrial invertebrates play multiple key roles in an ecosystem such as pollinating and serve as a food source for both aquatic and terrestrial organisms. The objective of this study is to provide a preliminary observation of terrestrial invertebrate communities between impacted, minimally impacted, and reference conditions sites so that further research can be conducted and add another aspect to shoreline management and restoration decisions. The impacted and minimally impacted sites that were sampled were located along the shore of Lower Saint Regis Lake on Paul Smith’s College property. The reference condition site sampled in this study was located along the shore of Black Pond on Paul Smith’s College VIC property. Invertebrates were sampled using pitfall traps and sweep nets. The invertebrates were then identified by taxonomic family and preserved in vials of alcohol. The findings of this study may imply that there may be inverse relationship between insect populations and arachnid populations based on impact level. Due to seasonal conditions of the Adirondacks, the results of this study could have been influenced by weather conditions, so a similar study conducted during a different season may produce vastly different results. The information collected in this study can be used to determine shoreline restoration and management decisions in the future.

Promoting ALT Awareness & Mission Objectives Through Interpretation on the Glenview Property

Fri, 12/14/2018 - 21:44
Abstract: The Adirondack Land Trust (ALT) purchased the Glenview property in October of 2016 for a discounted price of $98,000 in conjunction with the promise to preserve the scenic vista for which this property is well known. The 238-acre property located on NY State Route 86 is a popular roadside vista near Donnelly’s Ice Cream Stand that draws many visitors. The ALT not only wishes to preserve the scenic vista but several important features of the property. These include pollinator habitat, wetland ecosystems, and maple syrup production. It is believed that awareness of these important characteristics and the ALT can be increased through meaningful and relevant public engagement on the Glenview property. What follows is part of a larger plan for an interpretive nature center located on the site. This paper outlines what interpretation is, why interpretation is important, and how interpretation on the Glenview property can be used to promote the ALT mission objectives.

Lyme Disease in the Adirondacks: Using Domestic Canines as Sentinels for Human Risk

Tue, 12/05/2017 - 14:46
Abstract: Lyme disease (Borrelia burgdorferi) is the most prevalent zoonotic disease in the United States. With an increase of cases every year in new areas, it is crucial that researchers and veterinarians use sentinels, such as canines, to determine the prevalence of Lyme disease in emerging areas where tick density may be low. The main objective of this study was to determine the annual infection rate of Lyme disease in canines in Franklin and Essex County. An immunologic assay was performed to determine percent of canines exposed to Lyme bacteria as well as timing of exposure. Thirty-four random blood samples were collected from a local veterinary office during routine health screenings, and analyzed for Borrelia burgdorferi antibodies. Out of the thirty-four samples, two canines were positive for OspC antibodies (indicator of early infection) and three were positive for OspF (indicator of chronic infection). The annual infection rate for the 2017 year was 5.9%.

Riparian log gardens: examination of vascular plant communities and moss on logs in waterbodies

Tue, 12/05/2017 - 19:51
Abstract: Microsites can play a major part in facilitating plant diversity. Specific physical characteristics of microsites can create favorable conditions for certain species by isolating them from competition or protecting them from herbivory. Plant communities and woody debris can also facilitate the growth of other plants. I examined relationships between moss and vascular plants on log gardens in waterbodies to determine correlations between these organisms. I hypothesized that riparian log gardens, large woody debris in lakes and ponds supporting mats of terrestrial vegetation, serve as sites that may harbor rare species or have high plant species diversity. I also examined the relationship between bryophytes and plant communities based on the idea that bryophytes influence microsite characteristics. Knowing where rare species are harbored and what microsites encourage high diversity are important for preserving species. I surveyed plants on large woody debris in lakes and ponds in the northern Adirondacks and calculated the richness and diversity of the communities in relation to the presence of mosses. I found that logs that supported moss mats had more plants. The mean species richness of the riparian log gardens was 8.6 for all plants and 6.3 for herbaceous species. Some significant positive correlations were found for log area, log hardness, mat area, mat depth, and vascular plant diversity.

Affordable Sustainable Housing in the Urban Environment

Sat, 05/06/2017 - 21:26
Abstract: This paper addresses the lack of sustainable affordable housing in the urban environment. The focus of this study is the urban environment due to an increased rate of migration from rural areas to urban areas. This increase has led to a growing need for cities to become more sustainable in order to support the increasing population density. Focusing on the residential sector, cities have made great strides towards providing green-supportive and sustainable housing for their residents. However, the accessibility to sustainable housing in the urban environment for low-income residents is limited. The primary research questions this study addresses are what are the barriers to sustainable affordable housing in the urban environment, and how can we overcome these barriers? Through using secondary sources, the findings for this study were that the greatest barriers to developing sustainable low-income housing is the need for costly retrofits, and a lack of government subsidies. Addressing the second research question, the solutions to overcoming these barriers include: technological innovation, public-private partnerships, encouraging grass-roots groups, mixed-use development, and micro-apartments.
