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.

An examination of sustainable agricultural practices of small scale dairy farms in the Adirondack North Country of Upstate New York

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

Would an underpass/tunnel on Keese Mills Road decrease the percentage of amphibian mortality due to road mortality?

Wed, 04/29/2015 - 18:09
Abstract: Road Mortality has had a huge impact on Amphibian populations worldwide. Several options are available to help maintain and preserve migrating populations across roadways. One method that is looked at during this study is underpass and fencing. In this study, I assessed the need for an underpass and if it could help reduce the amount of amphibian’s mortality by traffic and, if an underpass is necessary, properly predict a location. I also looked at if underpasses alone could reduce the mortality of amphibians. I constructed arrays and pitfall traps to simulate an underpass on Keese Mills Road at Paul Smiths and Santa Clara, Franklin County New York. I predicted that underpass would decrease the amount of amphibian being slayed. I also predicted that certain locations would have more usage then others. The results showed that there was no significant difference between the location of the sites and whether they would be used by the amphibians. The results also showed that there was no correlation between the species that were captured and the species that were killed.

White-tailed Deer Browse Preference: A Comparative Study of the Catskill and Adirondack Mountain Regions, New York State

Tue, 05/05/2015 - 14:23
Abstract: Abundant white-tailed deer (Odocoileus virginianus) in New York State, United States, affect forest regeneration and stand composition through feeding (browse) pressure. White-tailed deer browse preference of six different hardwood tree species in two mountain ranges, the Catskill and Adirondack Mountains, within New York State were compared in order to determine the extent of browse selection by deer. There were no statistically different browse selection by white-tailed deer within the Catskills or Adirondack study area or between each study site. Visual analysis of the study areas after concluding the study revealed that red maple (Acer rubrum) was the preferred browse species at each study site.

The Effects of Varying Wavelengths of Light on Diatom Movement

Wed, 05/06/2015 - 16:18
Abstract: Diatoms were studied in order to determine in which wavelength of light they would be most active. It was surmised this knowledge would allow easier testing of future diatom movement hypotheses. This knowledge could, in turn, allow control over diatom movement in order to prevent or circumvent hazardous diatom blooms. Specimens were studied using a Parco scientific microscope in a dark room. They were studied both with and without cover slips to ensure the cover slips did not hinder movement. Sheets of high quality color transparency paper were laid over the microscope light, producing a single, strong color. In the end, the diatoms didn’t move at all, no matter the circumstances. The diatoms could have had no reason for movement or have been restricted by the small amount of water on the microscope slide due to the vast difference between the slide and the diatoms’ natural environment.

Examination of Potentially Ectoparasite-driven Behavior in Burrowing Owls: Tests of Alternative Hypotheses

Thu, 05/07/2015 - 19:06
Abstract: Burrowing Owls (Athene cunicularia) and their nests harbor at least 39 species of arthropods from 21 different families. Among the ectoparasites on Burrowing Owls are fleas, which are primarily Pulex irritans (Family Pulicidae), the human flea. Fleas can number in the hundreds on individual Burrowing Owls. Thus, we hypothesized that flea infestation has shaped Burrowing Owl behavior to avoid the costs of ectoparasitism. As part of experiments using infrared trail cameras deployed at Burrowing Owl nests in southern Idaho ¬¬during 2012-2013, we noticed apparent sunning behavior in both adult and nestling Burrowing Owls. Camera images captured owls lying on the ground with wings outstretched and flat. We only observed this behavior during daylight hours, although cameras were active for 24 h/day. Sunbathing in birds is often associated with ectoparasite reduction, although sunning has not previously been examined in relation to flea infestation. During 2014 we conducted an experiment that included fumigating some nests with a flea removing insecticide and examined the prediction that sunbathing would occur more frequently in control nests where ectoparasites remained. As sunning was not during the coolest parts of the day, it did not appear to function for warming. Also, we ultimately found no difference in the frequency of sunning in fumigated and control nests, and there was no relationship between sunning and abundance of fleas on owls. Thus, the evidence is not consistent with the ectoparasite hypothesis, as owls sunned irrespective of flea load. We also evaluated the alternative hypotheses that sunning was related to thermoregulation, anting, drying or feather degrading bacteria. The first three we were able to reject, and the last will need future research.

Acidic Deposition in Adirondack Lakes: Episodic Acidification and Equilibrium

Tue, 05/05/2015 - 10:06
Abstract: Acid deposition has been a historic problem in the Adirondacks. Though after original mitigation attempts were deemed successful, funding for many acid deposition-monitoring programs in the area has been cut or eliminated, and much of the data that has been collected is now old and outdated. Newer data on this issue needed to be collected to determine if there truly has been recovery of Adirondack lakes. Through this observational experiment the pH levels of 18 different lakes scattered around the Adirondacks during winter were examined. The pH levels of the snow around the lakes were examined to determine the levels of acid shock. This data was compared to the historic data available and created a preliminary finding. This comparison helped determine that Adirondack water bodies could possibly be coming to a form of equilibrium as the pH levels are possibly returning to a resemblance of pre-disturbance conditions, which suggests recent legislation may have had measurable successes in the goal of reducing the acidification of Adirondack freshwater ecosystems.

Comparison of Industry Standard 5/16” Maple Sap Tubing Versus 3/16” Maple Sap Tubing Regarding Overall Yields for the 2014-2015 Maple Syrup Season at Paul Smiths College Visitor Interpretation Center, Paul Smiths, New York.

Wed, 04/29/2015 - 20:17
Abstract: Obtaining the highest yields during a growing season has long been the utmost interest by maple syrup producers across the northeast. Methods have been introduced such as different tubing sizes starting at 7/16” tubing to the industry standard 5/16” tubing, however recently the newest tubing on the market is 3/16” tubing. Theoretically the new 3/16” tubing would provide the highest overall yields in comparison to 5/16” tubing by increasing the amount of vacuum present under a natural gravity system. The study of examining the flow of maple sap between two tubing types consists of two sugar bushes located at the Paul Smiths College Visitor Interpretation Center in Paul Smiths, New York in the Adirondack Park. The two sugar bushes were constructed on similar landscapes providing the same of the following I.) Slope, II.) Size of trees, III.) Growing conditions, and IV.) Number of taps. Measurements of canopy cover and tree diameter were also compared to determine the overall health of both plots. The analysis showed that both canopy cover and tree diameter were less in 3/16” tubing however more sap still was produced in 3/16” tubing. The test compared 5/16” tubing versus 3/16” tubing in regards to overall seasonal yields. The overall seasonal yields for both 3/16” and 5/16” were measured in gallons from two separate locations. 3/16” tubing yielded more overall, ending with a total volume collected of 324.75 gallons of sap, while the standard 5/16” tubing yielded 296.5 gallons.

A More Sustainable Computer

Tue, 05/05/2015 - 09:36
Abstract: The idea of a more sustainable computer has been looked at before by Fitzpatrick et al (2009). The project relooks at the idea and expands on it, discussing the production of a sustainable computer by larger companies for everyday household use. By putting together a computer in a compact oak casing, with minimal wiring, plastic and metal use, the project shows how you can make a budget friendly sustainable computer. An important part about sustainability is reusability. The availability of part reuse and recycling is also looked into to be able to make the most out of what has to be used. The results show a way in which it is possible to make a budget friendly, design for environment (DFE) computer that could be sold for everyday household use.

Reintroduction Feasibility of the Adirondack Wolf

Tue, 05/05/2015 - 11:14
Abstract: Mammalian carnivores are increasingly the focus of reintroduction attempts in areas from which they have been extirpated by historic persecution. The gray wolf (Canis Lupus) has been one of the most successful examples of large carnivore reintroduction around the world. The purpose of the study is to determine whether or not it is possible to successfully reintroduce the gray wolf into the Adirondack Park environment. Static and dynamic spatial geographical models were used to evaluate whether a proposed wolf reintroduction to the Adirondack Park is feasible. Ecological, economic, and sociopolitical aspects are limiting factors that are analyzed to determine if the reintroduction is structurally possible for the park.
