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.

Management Plan of the Ring-Tailed lemurs (Lemur catta) at Beza Mahafaly Special Reserve in Madagascar

Tue, 05/03/2016 - 11:29
Abstract: The need to protect Ring-tailed lemurs is evident. Lemurs are the most threatened group of vertebrates in the world with the IUCN listing 94% of lemur species as threated. This high percentage is in part due to the fact that lemurs only occur naturally in Madagascar so changes to the island effects the whole infraorder (Lemuriformes). Helping to curb illegal activities will protect not just the habitat for Ring-Tailed lemurs but will help the entirety of Madagascar’s Wildlife that has evolved on an island that used to be covered by up to 90% forest. These illegal practices are often protected by armed guards which may require assistance from the Madagascar government for adequate protection of the islands forests

Management of the Invasive American Mink (Neovison vison) Populations in the Southern Region of South America (Cape Horn Biosphere)

Tue, 05/03/2016 - 11:24
Abstract: American mink (Neovison vison) are an invasive species in South America, Europe and a few other countries. An invasive predator like the American mink can have negative effects on ecosystem function. In the Cape Horn biosphere, mink have no natural predators and have established themselves as top predator in that ecosystem (Crego 2015). Their populations have steadily increased in the Cape Horn Biosphere Region since their release from mink farms in 1930 (Ibarra et al. 2009). The Cape Horn biosphere is affected by the loss of native fauna such as Magellanic woodpeckers (Campephilus magellanicus), Olive Grass Mouse (Abrothrix olivaceus), and different types of ducks (Anseriforms) due to American mink predation. The Cape Horn Biosphere is a research, education, and conservation land that is used by institutes and universities (Ibarra et al. 2009). There are four objectives to help prevent the further spread of the invasive American mink that include: Educating the general public in the Cape Horn Biosphere region on the negative implications of invasive species, increasing the number of minks trapped by 15% in 1 year, setting environmental laws against the release of mink from fur farms within 5 years, creating a tactile agency to enforce those laws within 5 years. When all objectives are complete there will be a decreasing trend in American mink populations in Southern South America.

A Comparison Study of Adirondack Region Clearcutting Implementation to that of Paul Smith’s College VIC FERDA Plots

Mon, 05/02/2016 - 10:44
Abstract: The students of Paul Smith’s College have a unique opportunity to explore the parameters of silviculture and forestry practices. Gaining the base knowledge of silvicultural systems while also, properly implementing timber harvesting methods in order to achieve the specific goals and objectives of these systems is tremendously useful for implementation in future years. This study investigated the silvicultural prescriptions of the Forest Ecosystem Research and Demonstration Area (FERDA) plots on Paul Smith’s College lands, in Paul Smiths, New York. Comparing the inventory of the two clearcut sites upon these lands to that of other harvests within the Adirondack Park can supply further knowledge on what can be expected after a specific silvicultural system. Clearcutting has the greatest effect on forest succession by removing the forest cover and allowing light to reach what was once a shaded forest floor. Comparing experimental five acre clearcuts to that of larger commercial clearcuts in the same region can further our understanding of regeneration composition after such timber harvesting operations occur. The variance between the age of the FERDA plot harvests and the age of the harvests completed on Landvest timberlands resulted in varying data. However, if four to eight more years was given for pseudo FERDA plots to mature, it is believed that these harvests would be similar in composition and structure.

Monitoring the Zebra Mussel Invasion Front: Use of New Technology

Thu, 02/09/2012 - 15:39
Abstract: Zebra mussels are invasive mollusks that are affecting the well-being of the water bodies in the United States. This study uses environmental DNA (eDNA) is a sensitive early detection system that may be useful in monitoring their spread. The purpose of this study is to determine the effectiveness of eDNA technology in identifying infested water bodies, to determine if zebra mussel DNA is in the Adirondack water bodies not known to be infested, if the water chemistry of these water bodies is favorable for zebra mussel establishment, and if the eDNA technology is transferable to an institution like Paul Smith’s College. Eighteen lakes, all in New York State were sampled, fifteen of which are located in the Adirondack Park. DNA was extracted from water and plankton samples and species specific primers were used for PCR amplification to determine if zebra mussel DNA was present. Of seven samples taken from sites known to be infested, five of these tested positive for zebra mussel eDNA. Four lakes not known to be infested within the Park also tested positive for zebra mussel eDNA. Based on zebra mussel risk parameters (water chemistry) applied to 1,469 Adirondack water bodies, less than 3% are at risk of zebra mussel establishment. However it is possible that established populations could occur at microsites that may have locally high levels of calcium and higher pH.

Accommodation for the Deaf culture in hotels and recreational facilities

Mon, 12/05/2011 - 18:18
Abstract: Hotels and recreational facilities do not always have adequate accommodations, to help the Deaf culture communicate with the hearing world and take advantage of special services. Hotels and recreational facilities are improving their accommodation but more can be done to meet the needs for this demographic. This study will research what services are already available for the Deaf culture in hotels and recreational facilities. The outcome will determine what the Deaf culture prefers in accommodations, what hotels and recreation facilities offer, and new accommodations. This will help not only the Deaf culture, but everyone by breaking the language barrier between hearing and Deaf. The Deaf culture can benefit by utilizing new technology to have a more enjoyable experience at hotels and recreational facilities.
