Management Plan for Pacific Walrus (Odobenus rosmarus divergens) in Alaska, 2017-2027

Fri, 04/28/2017 - 18:06
Abstract: Pacific Walruses are social mammals and travel in herds. Most of the population spends the summer months in the ice pack of the Chukchi Sea; however, mostly adult males use coastal haulouts in the Bering Sea. Walruses use ice to rest between foraging trips, mate, care for their young, and defend themselves against predators. Climate reduced their ability to engage in these behaviors by eliminating the ice pack in their summer season. Walruses feed on bivalves on the sea bottom; however, because of climate change they no longer can reach the bottom. In response to the loss of ice, walruses are resting on land haulouts with as many as 20,000-40,000 individuals. This puts pressure on the benthic material supply. The swim from drifting ice to coastal haulouts can be hundreds of kilometers, which leads to the death of young walruses. Walruses are sensitive to sounds from ships, aircrafts, and tourist underwater and out of water. When walruses are disturbed by these events, they create stampedes by trying to dive into the water. The stampeding event ends in high mortality for calves. In 2007, more than 1,000 walruses were trampled to death in Chukotka, Russia. To prevent human disturbances, management at haulouts needs to occur for 10 years (2017-2027). The goals are to improve demographic knowledge of pacific walruses, minimize stampeding events, and grow and replace native bivalves near land haulouts. This could be accomplished by laws that require aircraft and vessels to maintain the appropriate distance. Creating artificial habitat would result in less use of coastal haulouts which would decrease mortality during stampeding events. It would also provide easier access to bivalves for foraging trips. Bivalves are depleting near land haulouts due to large demand from the high density of walruses, therefore aquaculture is needed to replace their food source. Harvesting more of the adult population would be essential to maintain the population from going over carrying capacity. If the adult population decreases then fewer calves will die in stampedes. These objectives are necessary to ensure the future of walruses and their new habitat.

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.

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.

A Taste of the Sustainable Sea

Thu, 12/11/2014 - 12:08
Abstract: A Taste of the Sustainable Sea is a capstone project revolving around the topic Sustainable Seafood. We were asked to pick topics out of hat and from there on a $300 budget create a menu to our liking and serve to no more than twenty people. This particular project was a cold dinner, served minimalist style, to ten people. Each course was about two to four bites each giving the customer a "taste" of everything. Inside of this project, you will find costing, recipes, front and back of the house descriptions, pictures and the lit review. Sustainable Seafood is a new and upcoming topic that will only revolve more over time.

Optimal Clutch Size of American Kestrels (Falco sparverius) in Northern New York

Mon, 04/28/2014 - 12:08
Abstract: American kestrels readily use nest boxes, which makes them perfect candidates for studies on nesting activity and success. Nesting success is important to understand so that managers can effectively assess the productivity of a breeding population of kestrels. The goal of this study was to determine optimum clutch size for American Kestrels in Northern New York. The hypothesis was that optimum clutch size consisted of four eggs per clutch. The objective was to determine what clutch size is most effective at hatching young. The study was conducted during the months of June 2013 through August 2013 on 150 nest boxes that were established in 2002. The contents of each elevated nest box were observed using a video baby monitor attached to an extendible pole to minimize disturbance. Clutch size data and number of chicks hatched was compiled and analyzed using a Kruskal-Wallis test. This test was used because it allowed data to be separated into different clutch sizes, and determined the significance between the number of eggs in each clutch and the number of chicks hatched. Clutch sizes varied from 1-5 eggs, with occurrences of one and four eggs being most common. The majority of nesting attempts with one egg failed, resulting in a low probability of chicks hatching from one egg clutches. A clutch size of four eggs has the highest probability of successfully hatching chicks and the highest mean number of chicks hatched compared to the other clutch sizes.
