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.

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.

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.

Food Allergies, Dietary Restrictions, and the Foodservice Industry

Thu, 12/03/2015 - 22:59
Abstract: For modern culinary professionals, food allergies and restricted diets present one of the biggest challenges in daily work. Ranging from an anaphylaxis-triggering peanut allergy to a preference for avoiding meat on Fridays, dietary restrictions and food sensitivities cover a wide variety of potential hurdles, and potentially inspirational guidelines, which foodservice professionals must navigate in order to be successful. On one side, a rise in the number of those with allergies or dietary restrictions presents an added challenge, but on the other, it presents an opportunity. Diners with such restrictions are becoming more and more comfortable with going out to dinner; that there will be some accommodation is now expected by consumers, rather than hoped for. The definition of “food allergy,” according to the Mayo Clinic, is “an immune system reaction that occurs soon after eating a certain food.” However, according to many experienced foodservice workers, the definition is “an annoying request from a customer who’s probably lying, anyway.” Of the many challenges contemporary chefs, culinarians, and food service professionals face, food preparation and service for those with allergies and restricted diets is one of the most prevalent, as well as one of the most misunderstood. Foodservice professionals will tell you that some of the most [annoying, silly, overblown, difficult, frightening] requests they receive while working are for special adjustments to accommodate a food allergy. When a chef is asked if the signature pasta dish can be made without gluten, his reaction is too often a mix of ire, disgust, and even embarrassment. Should a patron make a simple request that his or her food be prepared away from peanuts, images of anaphylactic shock and ambulances in the parking lot dance demonically through the front-of-house manager’s head. Such requests, however, seem to be popping up more and more often in our world. According to the CDC, “The prevalence of food allergies among children increased 18% during 1997-2007.” About 15 million Americans suffer from food allergies, as well as about 18 million Europeans. With such a rapid increase in those numbers, one would think the opportunity to impress customers with special diets might make a chef happy, rather than feeling as though he has been offended. The patience of chefs grows thinner still, however, when such requests are not a matter of health, but a matter of preference. For those who, for various reasons, adhere to a vegetarian or plant-based diet, or who follow certain religious dietary restrictions such as Islamic Halaal, finding a restaurant where the staff is ready and willing to accommodate can sometimes be difficult. For contemporary food handlers, ethics and morality play a massive role in serving such customers. A vegetarian diner, for example, may not know that the house minestrone soup is made with chicken stock in place of vegetable stock. Even after eating the soup, that customer will likely never know. In such situations, the decision to serve certain foods comes down to how much respect for his or her customers a chef has. It is my belief that the largest contributing factor towards the negative feelings chefs harbor over dietary restrictions is a lack of education and experience in handling such requests. Things unknown have always been a source of anxiety for a majority of human kind. That anxiety is why we are explorers and innovators; we subconsciously want to make things known. In order for foodservice professionals to handle the large number of diners who now request special items, it is necessary that they be educated from the earliest stages of their careers to expect, to accept, to interpret, and to enjoy working with those types of challenges. By doing so, the food and beverage industry will be a much more friendly world for all consumers, and a much more profitable one for all industry professionals.

Cheese

Tue, 05/05/2015 - 17:05
Abstract: This culminating experience happens in two phases. Throughout the semester, students have been taking on the role of Executive Chef in our Palm Restaurant. They have each created a menu, ordered food supplies, developed budgetary proposal, and assigned duties pertaining to food production and front of house service. Each dinner took on a different food related theme that the students researched and developed. This poster session provides the students to describe their process, their findings, and what they learned from the experience. My theme was based on cheese.

Interactive Electronic Education at the Paul Smith’s Visitor Interpretive Center

Tue, 05/05/2015 - 16:30
Abstract: The use of electronics in an educational setting is a debated topic, but certain kinds of programs are becoming more prominent. The purpose of this study is to examine how interactive electronic environmental education programs are used to facilitate environmental education, and attempting to determine whether or not the Paul Smith’s College Visitor Interpretive Center (VIC) could make use of them. Through interviews with key members of the Paul Smith’s College and the VIC as well as surveying the general public of both communities it was determined that these forms of educational programs were not in high demand by the users of the VIC, but electronic recreation tools were.

The Potential Distribution of Invasive Species Parallel to Climate Change at the Paul Smiths College Visitor Interpretive Center

Wed, 05/06/2015 - 13:17
Abstract: Human civilizations have been contributing to global climate change for as long as they have been altering the landscape. Whether it be from deforestation, to the release of carbon dioxide, we have been continually causing a greenhouse effect in the atmosphere. Due to warming temperatures, climate conditions have become more variable in the recent decades. A change of variability in the climate, also means a change in species distribution. As temperatures fluctuate in the Adirondack Park we may begin to see an increase in invasive plant species. Many invasive plant species have the ability to outperform native plants in regards to changing climates and eventually take over an area. The purpose of this study is to determine which plant species are most likely to make their way into the Paul Smiths College Visitor Interpretive Center, parallel to climate change, and what may be done to prevent or mitigate this new, potential alteration to the landscape.
