The Egg

Wed, 12/14/2016 - 11:10
Abstract: In this capstone we researched the egg. We explored the different components that make up the egg, the different vitamins, minerals and proteins that are found in an egg and the grading process that they go through. We talk about the history and where eggs in fact came from and how they came to be so commonly used, as well as their baking and cooking applications.

Salt

Wed, 12/14/2016 - 12:54
Abstract: For our capstone project we got the ingredient salt. There is a lot about salt that most people do not realize and so within this paper we want to let you know what we learned about salt. That includes the history of it, the many different types of salt and where they come from and also how they are used in culinary and baking. We also included in the paper how we used the ingredient throughout our five course meal. Some salts even have other uses that do not relate to cooking or baking and are still explained throughout the paper.

Analysis of Forage Quality in Adirondack Macrophytes: Implications for Waterfowl Nutrition

Fri, 04/29/2016 - 14:48
Abstract: To understand the relative nutritional value of macrophyte food sources for Adirondack waterfowl, the forage quality of four common Adirondack macrophytes were assessed. An analysis of two native pondweeds (Potamogeton) and two invasive watermilfoil (Myriophyllum) was conducted to deduce how invasive and native macrophytes compare in their relative concentrations of nitrogen and mineral content; important indicators of forage quality for waterfowl. Nitrogen content is used as a metric for relative concentration of protein. Macrophyte species were sampled from four Adirondack lakes of the same trophic status to account for effects of lake nutrient characteristics on plant nutrient uptake and synthesis. Total nitrogen was determined with the Kjeldahl procedure using flow injection analysis. Ash (mineral) content was acquired through high-heat burning in a muffle furnace. The invasive watermilfoil species had a higher percentage of nitrogen than the native species. There was no significant difference in the ash content between the species. It is critical to understand the ecological function of these species in relation to wildlife populations. The nutritional value of these aquatic macrophytes may have implications for the fitness and distribution of breeding herbivorous waterfowl in Adirondack lakes. These results may indicate that invasive plants will serve as a viable food source for herbivorous waterfowl as watermilfoil continues to spread across Adirondack aquatic systems.

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.

Forest Structure and Composition in the Smitty Creek Watershed

Wed, 12/14/2016 - 09:56
Abstract: The 2016 Smitty Creek CFI (Continuous Forest Inventory) study addressed the issue of creating a reliable and repeatable inventory design to examine general forestry trends and their relationships with the watershed itself. Identifying these trends and their consequences is important when considering factors linked to climate change, such as carbon storage and allocation. The objective of this project were as follows: establish 10 new CFI plots, monitor and record for signs of disease and insects, tree mortality, and overstory wildlife habitat, accurately estimate forest carbon sequestration, record understory composition in a 1/50th acre area around each plot center, and suggest methods and reasons for application in Paul Smith’s College CFI capstone projects. The study was conducted within the Smitty Creek watershed in Paul Smiths, NY with the plots falling on a transect that runs north and south. At each plot, trees within the radius were assigned numbered aluminum tags, trees were measured at diameter at breast height, and other features, such as snags, were recorded. Upon completing the project, 10 CFI plots had been created and their locations were recorded, several diseases and forest health concerns were identified, as well as, tree mortality and wildlife habitat considerations, carbon sequestration for the watershed was modeled over the next century, and a CFI project was designed for the Paul Smith’s College land compartments. The Smitty Creek watershed CFI project is repeatable and has an accurate baseline of information for future studies, and the Paul Smith’s College land compartments CFI plot design is ready for implementation.

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.

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

Recovery and Management Plan for the Houston Toad (Bufo houstonensis) in Bastrop County, Texas

Tue, 05/03/2016 - 11:24
Abstract: The Houston toad (Bufo houstonensis) was the first amphibian listed under the Endangered Species Act in 1973 and has been extirpated from 3 of 12 counties of its historical range throughout Texas. The driving factor of Houston toad declines is habitat loss, primarily via fragmentation and destruction from expansion of cities. The Lost Pine Ecoregion in Bastrop County, Texas holds the largest remaining populations in the Bastrop County State Park and the Griffith League Ranch. The proposed recovery plan is designed to accurately assess the current population sizes within the Griffith League Ranch and Bastrop State Park and increase the survivorship of adults and juveniles within the populations. Issues involving invasive species, predation, cattle grazing, and public awareness of Houston toads and actions to resolve the issues are addressed throughout the management plan. The success of this management plan is critical to increase Houston toad populations within its native range and decrease potential of extinction.

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.
