Comparison of Fine and Coarse Organic Matter Among Levels of Shoreline Impact: Implications for Ecological Restoration

Mon, 05/01/2017 - 15:24
Abstract: Human lake shoreline development has been shown to have impacts on the dynamics of the lakeshore. Such dynamics include the riparian and littoral zones interactions; the complexity, abundance, and residence time of large woody debris; organic matter/detritus, and food webs for fish, birds, and macroinvertebrates. Understanding such dynamics, and the impacts of human development, are important when attempting to restore the shoreline through the process of ecological restoration. The objectives of the study were, (1) to compare the amount of organic matter (smaller than sticks, branches, logs, and trees) among three levels of impact (impacted, minimally impacted, and benchmark), (2) to compare the amounts of CPOM and FPOM among the three levels of impact. The field data was collected using a modified design of sediment corer. A total of 63 samples were taken and the results clearly showed that the reference (benchmark) site had a much higher accumulation of organic sediment along the shoreline. Also, the data analysis also showed that there was virtually no measurable FPOM among the impacted and minimally impacted sites, but among the references sites it was more abundant than CPOM, which was opposite from the impacted and minimally impacted sites.

A Comparison of Leaf Litter in the Aquatic, Terrestrial, and Transitional Zones among Impacted, Minimally Impacted, and Benchmark Conditions of the Shorelines of the Lower St. Regis Lake and Black Pond

Mon, 05/01/2017 - 17:55
Abstract: Human development of shorelines impacts structure and functionality of the shoreline’s ecosystems. Ecological restoration projects can be used to rectify this impact, but first data must be collected to determine the extent of impact human development has had on the shoreline. The objective of this study was to compare the biomass (wet and dry weights) of deciduous and coniferous leaf litter among impacted, minimally impacted, and benchmark shorelines and between terrestrial and aquatic zones. Data was collected among the three impact levels on the Paul Smith’s College property along the shores of Lower St. Regis Lake (impacted and minimally impacted) and Black Pond (benchmark). Deciduous and coniferous leaf litter was collected in the aquatic and terrestrial zones of the shoreline and among the three impact levels using 0.7 m2 terrestrial and 0.25 m2 aquatic quadrats, and then compared using nonparametric statistical tests to determine differences among impact levels and between zones. The results of this study revealed that the relationship between deciduous and coniferous leaf litter was more nuanced than expected. The study supported the current body of scientific knowledge in that shoreline development decreases the overall amount of leaf litter accumulated in the shoreline of lakes. However, should future studies on variation between deciduous and coniferous leaf litter be conducted, the criteria for impact levels should be expanded to ensure the sites used are more comparable in forest type.

Does the presence of Malus spp. increase the fertility of the soil surface in pastures?

Mon, 05/01/2017 - 18:24
Abstract: Techniques to increase soil fertility in a pasture can benefit the system by combating soil degradation and increasing the health of vegetation. The use of apple trees (Malus spp.) may be particularly beneficial in achieving this due to reliable fruit yields, ease of management, and variety of suitable habitat. We hypothesized that soil directly under the canopy of apple trees would be higher in nutrients (C, Ca, K, Mg, N, & P) than soil in areas with no tree cover. Soil samples were taken from the top 15 cm of the soil surface under apple trees and in areas without trees at 14 sites in Massachusetts and New York. Samples were analyzed using spectrometry and color imagery to determine nutrient content. Potassium and magnesium concentrations were found to be significantly higher in under-canopy samples. Further research may expand these results and determine if the application of apple trees can be used to increase the health of pasture systems.

The Age and Origin of Lake Ejagham, Cameroon: 9,000-Year-Old Sediment Evidence Suggests Possible Bolide Impactor

Tue, 05/02/2017 - 15:18
Abstract: Lake Ejagham is a relatively small lake (54 hectares) located in the south-western region of Cameroon, Africa. Two sediment cores, EJ1 and EJ2, were extruded in 1987 by Dr. Dan Livingstone, preserved, and analyzed in 2016. Sediment and diatom analyses were performed in conjunction with radiocarbon dating, which suggests the maximum age of the lake itself is about 9,000 years old. The age of the lake was confirmed by both the radiocarbon dating of the sediment as well as the dating of wood fragments found at the base of the EJ2 core. The diatom analyses indicate that in recent times high percentages of planktonic diatoms were present, which suggests a relatively wetter hydroclimate than in the past. In the mid-section of EJ1 those planktonic diatom percentages were lower, which indicates drier climates or changes to the lacustrine environment. The consistency in the sediment and climate record suggest that Lake Ejagham has been uninterrupted by environmental catastrophes, which provided suitable conditions for endemic cichlids to evolve via sympatry, particularly Coptodon ejagham. Lake Ejagham has been thought to have formed as a solution basin, when water dissolves and carries away underground minerals forming a depression. Instead, the bedrock beneath the lake contains both soluble and insoluble layers, which prevent this from happening. Here we assert that the EJ1 and EJ2 cores support an alternative origin, possibly from a bolide impactor, however this is not conclusive.

Site Management Plan for the VIC-Quarry Wall

Fri, 05/05/2017 - 13:38
Abstract: Over time, the Paul Smith's College VIC (VIC) has evolved into a more accessible and enjoyable nature center for the community and the Paul Smith's College students. The VIC offers free and fee based activities such as arts, sports, and educational programs throughout the year, including bird and nature walks, children's educational programs, art exhibits, concerts, lectures, workshops, and naturalist-led paddles (Discover the Adirondack Mountains at the VIC, 2017). Starting a management plan for an outdoor rock climbing wall, located on the VIC property, involves many aspects and considerations. These specifications must then be effectively evaluated to start a functioning program.

Feasibility Study of Running a Summer Day Camp at the VIC

Mon, 05/08/2017 - 19:28
Abstract: Since the late nineteenth century, summer camp has been a part of the lives of American children; over the years it has transformed from a place for young boys to learn “manly things” to a place where parents can send their children for a summer of experience, education, and memories (Van Slyck, 2006). According to the American Camp Association, there are over 14,000 day and overnight camps in the US with approximately 14 million children and adults in the US attending camps annually. Recent research has shown the many benefits of sending children to summer camp, which includes physical, educational, and social benefits. The Paul Smith’s College VIC consists of 3,000 acres including 25 miles of trails for recreational use by the public and an interpretive center used for art shows and environmental education. Their mission is “to connect outdoor recreation, experiential education, and the arts, naturally.” Through the vast amount of land and use of the interpretive building, the VIC could potentially be the ideal location for a summer day camp. There are several other factors to consider in whether or not the VIC is a feasible location to run a day camp; these include products and services offered, the target market, marketing strategies, organization and staffing, annual scheduling,technological analysis, financial projections, and recommendations. The mission of this potential day camp is to connect children with nature, the environment and each other, fostering learning, environmental stewardship, and friendship. Through this study, it has been determined that a day camp is feasible - it would take some time however, to get funding, licensing, insurance, staff, etc. into place before the program could be implemented.

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.

Forest Structure and Composition in the Smitty Creek Watershed

Wed, 12/14/2016 - 09:56
Abstract: The 2016 Smitty Creek CFI (Continuous Forest Inventory) study addressed the issue of creating a reliable and repeatable inventory design to examine general forestry trends and their relationships with the watershed itself. Identifying these trends and their consequences is important when considering factors linked to climate change, such as carbon storage and allocation. The objective of this project were as follows: establish 10 new CFI plots, monitor and record for signs of disease and insects, tree mortality, and overstory wildlife habitat, accurately estimate forest carbon sequestration, record understory composition in a 1/50th acre area around each plot center, and suggest methods and reasons for application in Paul Smith’s College CFI capstone projects. The study was conducted within the Smitty Creek watershed in Paul Smiths, NY with the plots falling on a transect that runs north and south. At each plot, trees within the radius were assigned numbered aluminum tags, trees were measured at diameter at breast height, and other features, such as snags, were recorded. Upon completing the project, 10 CFI plots had been created and their locations were recorded, several diseases and forest health concerns were identified, as well as, tree mortality and wildlife habitat considerations, carbon sequestration for the watershed was modeled over the next century, and a CFI project was designed for the Paul Smith’s College land compartments. The Smitty Creek watershed CFI project is repeatable and has an accurate baseline of information for future studies, and the Paul Smith’s College land compartments CFI plot design is ready for implementation.
