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.

Rooted Education: learning from aquaponics

Sat, 04/30/2016 - 15:02
Abstract: Aquaponics is the integration of soil-less agriculture (hydroponics) within closed-loop aquaculture systems to reduce the toxic accumulation of nutrient waste from aquatic animals. Bacteria naturally establish to purify water by oxidizing the ammonia secreted by fish, which reduces the toxicity of effluent while creating a usable nitrogen source for plants. The conversion of ammonia and nitrite into nitrate by living bacteria communities is called a biological filter, or biofiltration (FAO 2014). Aquaponics would not be possible without biofiltration; the slightest amount of ammonia would be fatally toxic to fish, and plants wouldn't receive the nitrates they need to grow. There are unique opportunities offered by an aquaponics system to learn about ecological and human communities. 1.1. Aquaponics enables users to grow fish and agricultural plants with limited space and resource use (water, soil, and time). This enables an aquaponics user to invest less physical energy and time into expanding sustainable food resources for their household use. 1.2. A small aquaponics system could promote cultural values of self-sufficiency, energy consciousness, and connection to food systems. It could inspire individual efforts to produce food for one’s household, to build healthier and more resilient systems, and a greater appreciation for farming. Therefore, this project aims to actualize a mobile and functional aquaponics system for the educational benefit of the Paul Smith's College community. I will provide the background knowledge needed to maintain an aquaponics system, as well as describe the general concept of aquaponics design.

Roots of Paul Smith’s - Interpreting Our Past to Inspire Our Future : A conceptual design for an interpretive trail guide exhibit on Paul Smith’s College campus

Tue, 05/10/2016 - 13:17
Abstract: It is a pivotal time for Paul Smith’s College (PSC) where many of those directly involved with its inception are no long with us. PSC history was shaped by the Adirondack wilderness and together they influence how the college is run today. This project aimed to create the conceptual design for an interpretive trail exhibit on PSC campus. I worked with a professional exhibit designer to develop artistically inspired signage using archival photos to bring to life the heritage and natural history of the Paul Smith’s. Extensive research, input from stakeholders, and professional design guidance were utilized to create the content for six interpretive signs, a conceptual design, two formative evaluations, an estimated budget, and two campus sustainability fund proposals. These signs are meant to engage and inspire the current and future members of the Paul Smith’s College community, to build a deeper appreciation for the heritage that makes us unique.

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.

Topaz Detailing

Wed, 04/29/2015 - 11:21
Abstract: Topaz Detailing plans to be the only mobile detailing presence in the northern Bergen County NJ area that people trust their cars with. Trust us how? Trust us in making their car look as good as or better than the day they drove it off the lot. The service that Topaz Detailing provides uses a very safe paint correction process that has been in used all over the world for many years. The process can be used to correct anything from holograms, swirl marks and shallow scratches in the clear coat of the car caused from daily driving and use of improper materials. Using this method by repeating certain key steps can remove up to 100% of the visible blemishes on the paint can be corrected while making the car look like new. The full paint correction process starts with a basic waterless wash with distilled water and lubricants to get rid of most of the contaminants. Second, the car will be clayed to remove the contaminants were not removed from the first step and that can’t be seen. Third, the car will be compounded with a dual action orbital polisher to remove most of the swirl marks and scratches, this step may be repeated as many times as necessary to achieve desired results. Fourth, the car will be polished with oils; this will give the car (especially darker ones) a high gloss as well as remove very minor swirl marks. Finally, the car will be given two thin protective coats of wax which helps improves appearance as well as act as a barrier that will protect the paint from the elements. This simple process is what automotive detailers around the world use. Short-term goals for Topaz Detailing would be to stay in business and expand our customer base so we can saturate the market in Northern Bergen County and surrounding towns. Long-term goals would be to expand the business and get a garage so detailing can be done in the winter months and on rainy days. Another automotive detailer will be hired to operate the van and still keep our business mobile. What makes Topaz Detailing special: as opposed to the competitors in the area, Topaz Detailing will be run out of a van. This gives the company a few specific advantages A) customers will find it more convenient that the detail shop comes to them B) they will not have to worry about getting the car they need to detail to the shop and find a ride back and C) customer will not have to waste any valuable time getting the car to a shop, we come to you!

Assessing Activities and Policies to Improve Outing Club Participation

Wed, 04/29/2015 - 19:48
Abstract: College outing clubs have proven to be very beneficial for college students of all ages and fields of study. Research shows that outing programs, outdoor education programs, and adventure education programs can have a terrific impact on student’s mental, physical, and spiritual health. This study aims to assess activities and policies that could potentially increase participation in the outing club of Paul Smiths College in the Adirondack Mountains of Upstate New York. The questions this study intends to answer are: 1.) What types of activities will cause an increase in participation? 2.) What types of qualifications & experience should be required of guides and group leaders? and 3.) What can we do to increase organization or professionalism of our program? Using surveys, interviews, and credible sources, this study collected data from successful college outing clubs, the Paul Smith’s student body, and professionals in the field of recreation and summarized it into one collection of results with intentions of exposing ways to increase participation in the program and increase professionalism and organization of the program. Results exposed reoccurring themes regarding expectations for guide training, activities provided through other successful programs, and activities suggested by the student body. The student body survey revealed high support of technical skills seminars to teach students technical backcountry skills in a shorter period of time, and a high demand for high intensity activities such as white water rafting. Many responses supported the fact that in order to increase popularity in a program, the activities need to be demanding enough that individuals aren’t likely to partake in the activity without prior organization and qualified leadership. The results and data found in this study can be used in the future to develop outing club policies and procedures to aid in the success of the program.
