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.

Turning Points and the Ecological Conscience

Mon, 04/25/2016 - 08:15
Abstract: We live in a time when environmental crises seem to be overwhelming: global climate change, water crises, and mass extinctions, to name a few. Some people seek out ways to address environmental problems, while others remain ignorant or deny the existence of serious issues. Aldo Leopold’s land ethic calls those who help, people who feel “the stirring of an ecological conscience.” Many studies have looked at the psychology of environmentalism and the factors that instill an environmental ethic. Some studies look at early childhood, others at significant turning point events. Many factors foster an ecological conscience among people. I was interested in how the “stirring of an ecological conscience” was instilled in our own community here at Paul Smith’s College. The faculty and students all have a story to tell about what led them here and this project explored that. The sample studied here found that among faculty and students, experiences from childhood played a significant role in the development of an ecological conscience. These experiences most often influenced the path of each participants life journey. These findings provide us with information on ways we can look to help instill the ecological conscience in others, through education and daily life.

Roots of Paul Smith’s - Interpreting Our Past to Inspire Our Future : A conceptual design for an interpretive trail guide exhibit on Paul Smith’s College campus

Tue, 05/10/2016 - 13:17
Abstract: It is a pivotal time for Paul Smith’s College (PSC) where many of those directly involved with its inception are no long with us. PSC history was shaped by the Adirondack wilderness and together they influence how the college is run today. This project aimed to create the conceptual design for an interpretive trail exhibit on PSC campus. I worked with a professional exhibit designer to develop artistically inspired signage using archival photos to bring to life the heritage and natural history of the Paul Smith’s. Extensive research, input from stakeholders, and professional design guidance were utilized to create the content for six interpretive signs, a conceptual design, two formative evaluations, an estimated budget, and two campus sustainability fund proposals. These signs are meant to engage and inspire the current and future members of the Paul Smith’s College community, to build a deeper appreciation for the heritage that makes us unique.

Environmental Values Represented in Successful Green Building; LEED vs. Passive House

Mon, 04/28/2014 - 12:02
Abstract: In a society struggling to synchronize human development with environmental quality, the construction sector is often the target of sustainability initiatives. The purpose of this research is to investigate the environmental values and themes that influenced the design process of two successful green building projects. The two buildings at the focus of the study are new residential construction in the state of Maine; one with LEED Platinum certification and one with Passive House certification. Both buildings were found to exemplify themes of energy performance, practicality, and bioregionalism and included a collaborative design effort. A better understanding of these themes and values that guided these project teams to construct paradigm-shifting structures can help form a model for mainstream applications of a sustainable built environment.

Impacts of Maple Syrup Production Programming at the Paul Smith’s College Visitor Interpretive Center

Tue, 04/29/2014 - 12:37
Abstract: Education and interpretation provides strategies and techniques to successfully communicate natural resource and environmental concerns. This research addresses the effectiveness of a community education project at the Paul Smith’s College (PSC) Visitor Interpretive Center (VIC) in the Adirondacks of New York State. Educational programs regarding maple syrup production were designed and evaluated to determine their impact on the local community. The objectives were to offer skills education, raise awareness on a local resource, foster a connection to the land, and offer involvement in the VIC’s community maple project. The goal of maple education at the VIC is to educate the community in an attempt to encourage the growth of an underutilized sustainable local resource that community members can become involved in without degradation of Adirondack forests. Determinations were made using a survey questionnaire provided before and after the programs were performed. Based on the data collected the determination made is that the majority of participants that attended ultimately were interested in becoming involved in maple sugaring using to VIC as a gateway for maple sugaring, primarily as a hobby and outdoor activity. This research has aided in the determination that effective programming at the VIC results in encouraging the community to be involved in maple syrup production. With this determination the VIC will continue to perform the designed educational programs as a service to the community.

Maintaining the Population of Thornicroft Giraffes (Giraffa camelopardalis thornicroftt)

Sun, 05/04/2014 - 13:12
Abstract: There is a lack of information on the Thornicroft giraffe’s population size and of the amount of poaching taking place on the giraffes with in the Southern Luangwa Valley National Park. As of right now the giraffes population appears to be stable but there are a lot of factor unknown pertaining to the threats to the population and to their habitat. The goal of this management plan is to maintain the Thornicroft Giraffes population which is exclusively found in Luangwa Valley in Zambia Africa, the management plan is focused on the Southern Luangwa Valley National Park. With this management plan the objectives is to establish the population size within the park, maintain the preferred habitat of the giraffes, determine if poaching is taking place within the park and the potential effects poaching could have on the population. Once the population is known and stable then a harvest management strategy will be implemented for the locals. There will be pamphlets handed out in villages in the area; along with a survey used to access on poaching and the importance that giraffe based products have on their culture.
