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.

Turning Points and the Ecological Conscience

Mon, 04/25/2016 - 08:15
Abstract: We live in a time when environmental crises seem to be overwhelming: global climate change, water crises, and mass extinctions, to name a few. Some people seek out ways to address environmental problems, while others remain ignorant or deny the existence of serious issues. Aldo Leopold’s land ethic calls those who help, people who feel “the stirring of an ecological conscience.” Many studies have looked at the psychology of environmentalism and the factors that instill an environmental ethic. Some studies look at early childhood, others at significant turning point events. Many factors foster an ecological conscience among people. I was interested in how the “stirring of an ecological conscience” was instilled in our own community here at Paul Smith’s College. The faculty and students all have a story to tell about what led them here and this project explored that. The sample studied here found that among faculty and students, experiences from childhood played a significant role in the development of an ecological conscience. These experiences most often influenced the path of each participants life journey. These findings provide us with information on ways we can look to help instill the ecological conscience in others, through education and daily life.

Silvicultural Analysis of Northern Hardwood Regeneration at the Paul Smith’s College FERDA Plots

Mon, 05/02/2016 - 10:20
Abstract: In the northeastern forests most regeneration comes from natural regeneration that occurs after a disturbance. The Forest Ecosystem Research Demonstration Area (FERDA) plots located on the Paul Smith’s College VIC in the Adirondack Park are set up as an experiment to test different harvest methods in northern hardwood forests and see the results of each. We analyzed tree and sapling size class inventory data from clearcut, single-tree selection, and control treatments to compare regeneration present 14 years after the first harvests occurred. The clearcut treatments were the only treatments analyzed where American beech (Fagus grandifolia) was not the most abundant tree regeneration present. Both single-tree selection and control treatments were dominated by American beech with few other species present. Our results suggest that creating larger canopy openings, may allow species other than American beech, such as red maple (Acer rubrum) and yellow birch (Betula alleghaniensis) to become the most abundant species present.

Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

Sharing the John Dillon Park Experience with More Visitors: A marketing and management strategy, to increase visitor usage concentrating on organizations for people with disabilities and Veterans

Mon, 04/16/2012 - 17:54
Abstract: International Paper John Dillon Park (JDP) is a fully accessible campground managed by Paul Smith's College (PSC). Fully accessible means it was designed so anyone, regardless of the presence of a disability, can utilize the facility. The campground has not been near full capacity since it was opened in 2006. PSC wishes to increase those visitor numbers concentrating on Veterans and organizations for people with disabilities. A survey was conducted of the current park visitors to obtain information needed to help define the desired demographic and other information needed for the marketing strategy of JDP. These visitor responses showed that PSC needs to concentrate its marketing efforts into better contact with its current users to stimulate return users, make a few changes to the facilities themselves, and advertise within magazines, Veteran organizations, organizations for people with disabilities and Fort Drum. Also, the responses informed PSC that it needs to provide for the recollection phase of the recreational experience by selling JDP souvenirs. With an increase in the visitor usage of JDP, more people will be able to appreciate the serenity of nature and the camping experience JDP offers to all people.

Tracking the fire history and succession of the Bloomingdale bog

Mon, 04/16/2012 - 17:58
Abstract: This study examined core samples from the Bloomingdale bog. This bog was chosen for its great span over the landscape. The study was conducted in order to locate and identify changes that may have been induced by variation in local water tables from such things as climate change, change in ecosystem dynamics, and from degradation. Also, to establish the foundation information for future studies to expand on. This study included two transects across the bog. Each transect had seven points where samples where extracted. These points were selected randomly along each transect, as to avoid some bias in the study. We quantified the organic matter, the major transition layers, and four carbon dates. This data was used to determine the major transitions in organic material in the bog, when the bog experienced these changes, and a fire history pattern of the bog. In addition, the data showed where and when a possible significant drought had occurred in the bog. This study is the backbone for future studies perhaps on such subjects as climate change, watersheds effects on local wetland ecosystems, and a possible fire history for this area.

An Analysis of Possible Forest Type Shifts due to Asian Longhorned Beetle Invasion in the Northern Hardwood Forest of Hebron, NY

Mon, 04/16/2012 - 18:10
Abstract: The Asian Longhorned beetle (Anoplophora glabripennis) is an invasive alien insect that poses a severe threat to forests of the northeastern United States. If this insect is allowed to run rampant through our forests there will be huge economic and ecological implications. This study hopes to provide a better understanding of these potential implications and provide potential policies for managing and controlling this insect that has potentially devastating effects on the hardwood forests of the northeast. The study on hand will explore the effects on current forest types in Hebron, NY and what future regeneration may look like in the aftermath of an ALB infestation. ALB has the potential to completely change not only the landscape but also alter current markets based around the northern hardwood stand type. This study was designed to attempt to grasp the magnitude and effects of an infestation by ALB. Current policies were reviewed to attempt to create a possible set of management strategies that could be used to minimize the effects of the ALB. Possible forest type shifts were predicted for the area based upon species range and soil types present in the study area. It is important to understand not only what ALB is capable of but also what can be expected to happen if or when it does move through the area.

Analyzing 58 years of New York State stumpage reports for Sugar Maple (Acer saccharum), Red Oak (Quercus rubra) and White Pine (Pinus strobus): A real value price trend analysis

Mon, 04/16/2012 - 18:51
Abstract: The trends in stumpage prices reported for New York State fluctuate over time. Three popular species for saw timber in the state of New York are sugar maple, red oak, and white pine. This report produced trends that demonstrate the comparative value of each species over the reported time (58 years), as well as a net present value in 2011 dollars, providing a price trend after inflation was removed. Surrounding states, Maine, New Hampshire, and Vermont, have similar reports which are utilized by forest economists to assess investments. As of this point, New York does not have a stumpage trend analysis to compare forest value and productivity. This project examined the stumpage trends for each species and offers possible correlation between points in the trends and specific events. The trends are projected as dollar values over time. Market trend correlation examines the demand for saw timber between hardwood and softwood, with the addition of red oak as another popular saw timber species, and as a color preference factor. The effect of political constraints, in the form of forest preservation, was analyzed with respect to the overall impact on wood flow. Timelines for insect/disease outbreaks were correlated to the highlights of the stumpage trends.
