An Assessment of Heavy Metal Concentrations in Adirondack Waterfowl

Thu, 04/28/2016 - 22:53
Abstract: We analyzed heavy metal concentrations in waterfowl liver and breast tissue from ducks harvested within the Adirondack Park from October 3 to November 13, 2015. Interspecific, intersex, and feeding behavior variation in heavy metal concentrations were assessed. Waterfowl from two feeding behavior groups (diving and dabbling) were harvested from the watershed within a 50 mile radius of Paul Smith’s, New York. Harvested waterfowl species included mallard (Anas platyrhynchos), American black duck (Anas rubripes), common merganser (Mergus merganser), ring-necked duck (Aythya collaris), bufflehead (Bucephala albeola), and hooded merganser (Lophodytes cucullatus). Legal harvest of these species during regulated New York State duck hunting season allows for permissible use of internal organs for heavy metal determination. Dry weight (mg/kg) of digested liver and breast tissue samples were analyzed using atomic absorption spectroscopy. Due to unknown laboratory error, absolute concentration values were inaccurate, thus, rendering accurate analyses unfeasible. However, relative observable trends were able to be assessed given our data’s high precision. Analyte concentrations were significantly greater in liver tissues and there were significant differences between species. Variation in mercury, lead, bismuth, cadmium, chromium, and zinc concentrations in waterfowl serve as an indicator of the presence, cycling, bioaccumulation, and temporal trends of these metals in northeastern aquatic habitats.

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.

Silvicultural Analysis of Northern Hardwood Regeneration at the Paul Smith’s College FERDA Plots

Mon, 05/02/2016 - 10:20
Abstract: In the northeastern forests most regeneration comes from natural regeneration that occurs after a disturbance. The Forest Ecosystem Research Demonstration Area (FERDA) plots located on the Paul Smith’s College VIC in the Adirondack Park are set up as an experiment to test different harvest methods in northern hardwood forests and see the results of each. We analyzed tree and sapling size class inventory data from clearcut, single-tree selection, and control treatments to compare regeneration present 14 years after the first harvests occurred. The clearcut treatments were the only treatments analyzed where American beech (Fagus grandifolia) was not the most abundant tree regeneration present. Both single-tree selection and control treatments were dominated by American beech with few other species present. Our results suggest that creating larger canopy openings, may allow species other than American beech, such as red maple (Acer rubrum) and yellow birch (Betula alleghaniensis) to become the most abundant species present.

Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

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.

Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

Offal's and Less Popular Cuts

Thu, 04/24/2014 - 09:39
Abstract: The research question I develop and base my capstone project was based around the trend and concept of nose to tail dinning. I wanted to find out if using offal’s and second cuts of meat and could these items be suited for a family restaurant. I will also try to see if using offal’s and cross utilizing ingredients throughout the menu to cut down on waste, be cost effective and appeal to the guest. My menu will reflect the proper cuts of meat as well as providing the least waste. My methods will revolve around the practical use of my time given the restraints of my question as well as see if the theme can be practical within industry standards.

Vermont VS Canadian, A study of the differences between Vermont and Canadian syrup

Thu, 04/24/2014 - 20:07
Abstract: The research question for this capstone is one that I have long pondered. Can someone taste the difference between Vermont and Canadian syrup? The inspiration to use this as my capstone question came on the first day of class when chef Pino gave us an example of a capstone question, it was “Can you tell the difference between grade A light maple syrup and grade B?” upon hearing this I decided to use this capstone as a chance to test my long standing theories. As the question implies the menu uses entirely maple syrup based dishes with an even balance between the two types. There are two chicken based dishes that were used for the tasting. By using two identical dishes I hoped to better allow the tasters to make the call as to whether or not the two syrups are noticeably different. The menu also includes pork, beef and a pasta dish that all feature Maple syrup or sugar as a major part of the recipe. The questions to the patrons are designed to tell me if people could taste any difference between the two dishes and if there was any reasons other than the maple flavor that could have accounted for this. Also, if they could taste a difference between the two plates, could they distinguish which one is from where?

Grass Fed vs. Grain Fed Beef

Fri, 04/25/2014 - 08:29
Abstract: Popular in the media today are chefs that boast only the best ingredients, but can the consumer even tell? The question being tested is this, can the average American taste the difference between grass fed beef and commercial beef, with the grass fed being more expensive? This concept is beneficial to explore for two main reasons. Number one, if there is a noticeable difference; culinary professionals will want to use the best ingredients they can find because people can taste the quality. Number two, if the guest can’t tell the difference between two cuts of meat that vary significantly in price, why would chefs waste money on it? To test this theory I will be providing a sample of plates with same cut of beef however one raised on grass and the other on corn and grain. There will be a simple and short survey asking the guest to vote on their favorite dish and why they liked it. With this information, gathered from random people with varying age and gender, it will provide evidence for or against the use of grass fed beef in our restaurants today.
