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.

Creating a Reliable Surveying Network: Does Adding New Survey Control Points to Paul Smith’s College Campus Enhance its Current Network?

Tue, 12/05/2017 - 18:48
Abstract: The goal of the project was to improve the current geometry of the Paul Smith’s College surveying network. Four new survey control points were added to the current network allowing for new connectivity to old control points. Previously, there was a Westside network and an Eastside network that were not connected and by connecting these two networks, it has expanded the current network further into the campus. Two different methods were used to help identify the new network. A traditional survey method, a closed traverse, was used to connect the old control points to the new control points by utilizing a Nikon DTM-352 series total station. A X90 OPUS GPS unit was used to connect the new control points into a geodetic network. After the data was collected a least squares adjustment was done to the closed traverse to correct for error within the traverse. The GPS data was processed by Topcon Tools utilizing a Continuously Operating Reference System (CORS) to obtain a better level of accuracy for the network it produced. The two different techniques used produced different results in the overall survey networks and supplied different coordinates than what has been previously used by students at the college. These results gained from the project are not of a consistent level of precision and are not recommended for use without conducting more closed traverses to increase precision within the network.

Creating Universal Use for the Glenview Preserve

Fri, 12/15/2017 - 20:40
Abstract: The Adirondack Land Trust recently purchased 238 acres along Route 86 in Harrietstown. This tract of land is called the Glenview Preserve. The Adirondack Park Agency has already designated a scenic vista of Whiteface Mountain and the High Peaks. Along the back of the property is the Bloomingdale Bog, which is the third largest boreal peatland in New York. Vista like the Glenview Preserve, which doesn’t involve a climb and is also accessible to all. This poses the perfect opportunity to establish universal trails for all to enjoy. Conservation of land is made possible by connections that people make to the land. If there is no connection to nature, it could be destroyed without anyone speaking up. The location of this tract of land makes it ideal for accessible trail since there is no mountain to hike to get the view. Hiking is one of the oldest pastimes of the world. People can experience beauty every season of the year. It strengthens our bodies and minds at no cost. Hiking is a wonderful chance to feel the earth below your feet and get up close and personal with nature. Installing trails would not only open up recreational opportunities such as hiking, running, and bird watching, skiing and snowshoeing but also build community.

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.

Changes in aquatic communities resulting from interactions between climate change and invasive aquatic plants in the Adirondacks.

Thu, 02/09/2012 - 11:26
Abstract: Global climate change can act synergistically with invasive species leading to shifts in ecosystem structure and function. We assessed how a rise in water temperature influenced the potential competitive advantage of an invasive aquatic plant, Eurasian watermilfoil, (Myriophyllum spicatum) over a co-occurring native species northern watermilfoil (M. sibiricum). We also examined the interrelationship between water temperature, watermilfoil, and the aquatic ecosystem including periphyton growth and zooplankton abundance. The study was conducted using replicated mesocosms (3785-liter), with water heaters used to provide a range of temperatures. We found that increasing water temperature promoted the likely competitive advantage of the invasive species, M. spicatum: Survival of M. sibiricum plants was lower than that of M. spicatum across all temperature treatments with a mean survival rate of 24% and 96% respectively. M. sibiricum also showed significantly slower rates of plant growth (mean growth of 3.3 cm compared to 7.6 cm for M. spicatum) and reduced vigor compared to M. spicatum, with an average of less than half the number of growing meristems. Zooplankton densities averaged over 20 times higher in mesocosms with M. sibiricum compared to those with the invasive M. spicatum. Periphyton biomass was best explained by water temperature with an increase in growth in warmer water. Our study confirms that in the face of global climate change, the invasive M. spicatum will continue to exert dominance over its native counterpart. Our results also provide compelling evidence that the combined effects of climate change and invasive aquatic plants can dramatically alter aquatic ecosystems.
