Analysis of Forage Quality in Adirondack Macrophytes: Implications for Waterfowl Nutrition

Fri, 04/29/2016 - 14:48
Abstract: To understand the relative nutritional value of macrophyte food sources for Adirondack waterfowl, the forage quality of four common Adirondack macrophytes were assessed. An analysis of two native pondweeds (Potamogeton) and two invasive watermilfoil (Myriophyllum) was conducted to deduce how invasive and native macrophytes compare in their relative concentrations of nitrogen and mineral content; important indicators of forage quality for waterfowl. Nitrogen content is used as a metric for relative concentration of protein. Macrophyte species were sampled from four Adirondack lakes of the same trophic status to account for effects of lake nutrient characteristics on plant nutrient uptake and synthesis. Total nitrogen was determined with the Kjeldahl procedure using flow injection analysis. Ash (mineral) content was acquired through high-heat burning in a muffle furnace. The invasive watermilfoil species had a higher percentage of nitrogen than the native species. There was no significant difference in the ash content between the species. It is critical to understand the ecological function of these species in relation to wildlife populations. The nutritional value of these aquatic macrophytes may have implications for the fitness and distribution of breeding herbivorous waterfowl in Adirondack lakes. These results may indicate that invasive plants will serve as a viable food source for herbivorous waterfowl as watermilfoil continues to spread across Adirondack aquatic systems.

Walden Pond: Ecological and Anthropological History Reflected in the Sedimentary Record

Tue, 05/03/2016 - 23:13
Abstract: This study examined environmental changes reflected in the microfossil record of a sediment core taken in August 2015 from Walden Pond, Massachusetts spanning the last 600 years. In particular changes in the eutrophication status, inorganic sediment deposition due to land use, lake water depth and temperature were examined using phytoplankton indicator species—diatoms and chrysophytes— to reconstruct environmental conditions. The study site was a basin shallower and closer to the source of anthropogenic N and P inputs than the site of previous studies at Walden’s deepest basin, allowing for finer detection of changes in water level and organic content of sediment. A gravity corer was used to collect the sediment core to preserve topmost sediment layers for analysis, as more than a decade has passed since the last published study of this kind at Walden Pond by Köster et. al. (2005). Results show a significant increase in indicators of eutrophic lake conditions since European settlement ca. 1630, and especially since the 20th century. However, relative Asterionella formosa and Synedra nana abundances had not changed significantly in the last decade since Köster et. al.’s 2005 study, and have in fact decreased somewhat, suggesting water treatment efforts by the Massachusetts Dept. of Environmental Protection (DEP) have had some success. Loss on ignition (LOI) of organic content shows a precipitous decline from the mid 19th century from 37% to 22%, representing intensive land clearance and development until the 1970’s when DEP management began. After that point, LOI rose, perhaps due to increased lake productivity, and has fluctuated around 25%. Relative Discostella stelligera abundance, while used in the WAl-3 piston core as a proxy for water depth, could not be used in the WAL-1 gravity core from this study as eutrophication has significantly impacted their abundance. Chrysophyte scale:diatom ratios corroborate an observed trend of increasing abundance in lakes globally since the 20th century, perhaps in response to rising global temperatures over the same period.

Mon, 05/01/2017 - 09:14
Abstract: This study examines the sustainable practices of small scale dairy farms in the Adirondack North Country of Upstate New York. The results of this study can assist farmers in developing and implementing sustainable agriculture practices specific for small scale dairy farms in the North Country. Methods for research include farm tours as well as in person interviews with the farmers which will provide an understanding of what farming practices are currently being implemented as well as identifying what potential practices may be implemented. The information that is gathered can also be helpful with legislative processes. It may provide law makers and various agencies with valuable information that can help create guidelines and regulations that support sustainable farming methods as well as assist farmers in understanding their challenges and successes in reaching both economic and environmental sustainability

Presence and Abundance of Microplastics within Flowing Waters of Private, Wilderness, and Other Forest Preserve Lands of the Northern Adirondack Park

Mon, 04/28/2014 - 16:26
Abstract: Microplastic sampling was conducted at thirteen locations throughout the water bodies of the Northern Adirondack Region. Plastics were found at all thirteen sites, which were categorized by the impact level of human development. Any particle less than 5mm can be defined as a microplastic particle. Microscopic plastics can be found in a variety of chemical cleaners, clothing fabrics, and concrete solutions. Storm water drainage systems and wastewater treatment plants are confirmed sources of microplastic pollution, which carry pollutants into our rivers, lakes, and streams. Ingestion of microplastic particles can lead to many distinctive threats, including biological and physical abnormalities, while possibly leading to bioaccumulation and biomagnification throughout the food web. Future practices for management and prevention of microplastic pollutants in the Adirondacks is critical for environmental protection, while also portraying a worldly view of an overlooked human induced issue.

Alpine Ecosystems on Ski Area Summits in the Northeast: A Best Management Practices Manual

Mon, 12/01/2014 - 15:19
Abstract: Over the past half a century, anthropogenic climate change has triggered temperatures in the northeastern United States to rise. This increase has led to decreased winter precipitation and a longer annual growing season. Species found in upland/montane habitats on the southern edge of their range limits are particularly threatened by these changes. Warmer temperatures have allowed larger woody plants to advance up mountain slopes, entering the habitat of these fragile species. In the next decade, we will witness a complete disappearance of alpine flora from several locations across the northeast including Whiteface in New York, Sugarloaf in Maine and Mount Mansfield in Vermont. Managers of ski resorts can therefore play an important role in promoting the continued persistence of high-altitude flora and fauna through carefully considered management decisions can also serve to promote the reputation of the ski industry as stewards of mountaintop ecosystems. Doing so will allow for continued study of the species that exist within these communities, the protection of biodiversity, and increased revenue for the resort itself through elevated public image and mountain-top tourism. To help begin these conservation efforts, we have created a best management practice (BMP) manual to guide ski area managers in making these developments. It includes techniques for sustainable slope, soil, vegetation and wildlife management, erosion control, artificial snow production, and ski slope construction and design. Also included are marketing techniques and an overview of the economic viability of the practices outlined in this manual.

Possible Limiting Soil Macro-Nutrients of Sugar Maple (Acer saccharum) Growth in an Adirondack Hardwood Stand

Mon, 04/28/2014 - 08:46
Abstract: Sugar maple (Acer Saccharum) has been in decline for the past few decades. Several studies have been done throughout parts of Canada and New England to determine what is limiting sugar maple growth. By mimicking one of these studies, I conducted a fertility study to show correlations between soil fertility and three different measures of tree growth. I selected 40 dominant sugar maple trees in a hardwood stand in the Adirondack Park in northern New York to sample. I collected two increment cores from each tree, measured the DBH and calculated basal area at each tree. I also collected mineral soil from the base of each tree that was sampled and tested its chemical properties and macronutrients that are most related to growth. I found weaker correlations between soil fertility and growth than my parent study had found. This may be because I didn’t have enough variation in my samples, measured growth or fertility in a way that wasn’t the most accurate, soil characteristics may not be limiting, or some soil characteristics may be co-limiting growth.

Challenges Associated with Conservation Easements In the Adirondack Park and Recommendations for Improving the Process

Mon, 04/28/2014 - 13:11
Abstract: With conservation easements only becoming popular in the past 40 years, they are at the developmental stage where weaknesses start to become apparent as land starts to change hands from one generation to the next. It is important to find and correct these barriers to ensure these same problems do not occur in the next 40 years. My focus was performing research within the Adirondack State Park of New York. I utilized Semi-Structured Interviews (SSI) along with SSI guides to collect my data while using a sampling technique referred to as a snowball sampling approach. I interviewed two different categories of conservation easement personal. 1. Land owner/manager with conservation easement on property 2.Agency Workers from The Nature Conservancy and the New York State Department of Environmental. I then used emergent themes to reveal the discrepancies or weaknesses in current conservation easements along with their common strengths. From there I used (S.W.O.T) Strengths, Weaknesses, Opportunities and Threats analysis to provide recommendations for policy revising.

Python Scripting an ArcGIS Add-in for Wildlife Telemetry Data Processing

Mon, 04/28/2014 - 15:46
Abstract: There are currently no modern open source alternatives to commercial radio telemetry processing software. I developed a python add-in for ArcGIS which allows for interactive editing of telemetry data. The add-in was tested for functionality, accuracy and usability. Functionality was tested according to how closely it adhered to the original software requirements specification. Accuracy was tested by generating telemetry data from known animal locations and comparing the estimated locations to the actual locations. Usability was tested through speak aloud user tests. User data was collected on completion status, time of completion, and number usability issues found. The intended functionality goals were met and exceeded. Accuracy was less than expected with an average inaccuracy distance of 202 meters and approximately 10% of the bearing groups were unable to generate a centroid. During user testing, a total of 33 usability issues were discovered that hindered use of the software and on average it took a student 18 minutes to process one data set without prior exposure to the add-in. Qualitative observations from the user tests could be a launching point for GIS usability studies. In addition, the core modules could be modified and expanded into a separate application with dependency on Quantum-GIS or Geographic Analysis Support System (GRASS).

Is Green Construction Economically Feasible

Fri, 05/09/2014 - 14:12
Abstract: Green construction is a valuable part of our developing world. Building green will help reduce the negative effects of pollution in our atmosphere. It will also help reduce electrical uses throughout the household and allow you to have a reduction in costs to paying electrical bills. Too many, this process is considered to be expensive to build this way. Products that green homes are made of are considered to be expensive. The materials for energy production are also considered expensive. Too address this, a survey was conducted to see the views of individuals and what they believe it costs to have a green home. The survey also asked if people would consider having a green home if they had the option. It is proven having a green home will reduce the costs of a home eventually leading to paying nothing for maintaining a house called a payback period. To build green will mean to pay less over time and maybe eventually lead to getting paid. There are also many government incentives for building green. The government can invest in this building so you may afford a green building. It is well advised to be educated in all aspects of building green such as the tax incentives, payback periods, environmental effects, and how to approach this.
