A Comparison of Macro-Invertebrate Communities in Different Substrates among Impacted and Minimally-Impacted Sites on Lower St. Regis Lake and Benchmark Sites on Black Pond

Wed, 05/03/2017 - 21:34
Abstract: Many shorelines today have been impacted by human activities which has resulted in changes in macro-aquatic invertebrate communities. Ecological restoration can be used in efforts to bring macro-aquatic invertebrates back into shorelines. However, data is needed to better understand how macro-aquatic invertebrates can be used in these efforts as indicator species to determine community structure health and function. This project compared the macro-aquatic invertebrate communities in impacted and minimally impacted sites located on Lower St. Regis Lake and benchmark sites located on Black Pond. The two objectives to this project were to 1) compare the species richness among impact levels and 2) compare the density among impact levels. Each impacted level has three sites and at each site ten samples were taken in a systematic way which resulted in 90 total samples. Samples were taken to the lab to be sorted and for macro-aquatic invertebrates could be identified to the family level. The macro-aquatic invertebrate community was different among each impact level. The overall family diversity was greater at the benchmark sites than the minimally impacted and impacted sites. Dominate substrate type that had a greater presence of different families were sites that had organic matter. The findings of this study create a more knowledge base which can be useful for future ecological restoration efforts on the impacted and minimally impacted areas located on Lower St. Regis Lake and to educate the public on the impacts on macro-aquatic invertebrates and their communities.

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 Application of Silvicultural Treatments to Establish and Maintain Early Successional Habitat in the Adirondack Forests of New York State

Sat, 04/29/2017 - 15:12
Abstract: Early successional habitat (ESH) in New York state can be described as young forests comprising trees, shrubs, grasses, and other herbaceous plants that form relatively open canopies with dense understories. ESH has decreased due to nearly ninety percent of the naturally occurring shrublands of North America having been destroyed. The destruction of this habitat is of top concern due to the threatened and endangered species whom rely on these sorts of habitats to thrive. Considering the future climate projections, population models, and theoretical species distribution, responsible stewardship is needed to manage in favor of ESH types. A meta-analysis of various journals and databases was performed to synthesize information into a general management plan for establishing ESH in the Adirondacks. Through combining methods and silvicultural management practices from past plans in the northeastern United States, as well as background knowledge of the area, this management plan has been tailored specifically for an Adirondack forest. These outlined silvicultural treatments may also be extended to a variety of other forest types in the eastern U.S.A. Re-establishing young forests throughout the region is the goal of this plan. In doing so, these practices will enhance the health, resiliency, and biodiversity of the Adirondack region, and New York State by creating critical ESH which the fauna and flora of this region depend upon.

Tiny houses for families

Tue, 05/02/2017 - 20:54
Abstract: Houses have changed in size and style over the centuries. We looked at tiny houses and research the economic and social benefits and issues with raising a family in a tiny house. We limited the family to four and made our house 800 square feet. We looked at case studies of families who are currently raising a family in a tiny home to find out what they say their problems may be. We found many unexpected benefits in our research. Many families believe that aside from the economic benefits, raising a family in a tiny home forces the family to be close and to communicate with each other. We interviewed a contractor, Harry Gordon, who gave us information in the building of sustainable housing. There was also a survey we conducted from the Paul Smith’s Community. The survey gave us data on the amount of people who were willing to raise a family in a tiny home. In our results, we found that for those willing to try to raise a family in a tiny house, it is very feasible.
