Tardigrade Abundance in Green Shield Lichens on Different Tree Species

Wed, 04/24/2013 - 18:43
Abstract: Many studies have been done on tardigrades, a microscopic, aquatic organism that feeds on plant cell fluid, bacteria, algae, protozoa, and other small invertebrates. Most of these studies have addressed their ability to survive extreme environments and not their preferred living habitats. Virtually no studies have been done investigating the ecology of tardigrades. This study focuses on which species of tardigrade live on a species of lichen (Common Greenshield Lichen, Flavoparmelia caperata) found on three species of trees; Red Maple (Acer rubrum), Black Cherry (Prunus serotina), and White Pine (Pinus strobus). Five trees of each species were chosen and five samples of the Common Greenshield Lichen were taken from all 25 trees during each of the fall and winter seasons. From every lichen sample processed, five slides were looked at, each containing two drops of the water that the lichen was suspended in for 2 hours. The samples were looked at underneath a compound microscope and a dichotomous key was used to identify tardigrades that were found. Due to the fact that liquid water is less available in winter, samples were taken during the fall and winter to look at the differences in species diversity and abundance. The greatest abundance of tardigrades was found on Red Maple, during both fall and winter. Black Cherry had the lowest abundance of tardigrades during both fall and winter. White Pine had an abundance less than that of Red Maple but greater than that of the Black Cherry. There were more tardigrades found on the lichen in fall than in winter. This implies that they find Red Maple a more suitable habitat than the Black Cherry and White Pine, may be related to acidity of the Black Cherry and White Pine being greater than that of Red Maple. Throughfall and stemflow on the trees may also contribute to habitat preference of the tardigrades.

New York State Feral Hog (Sus scrofa) Management Plan: Species Eradication and Public Education

Thu, 04/25/2013 - 11:22
Abstract: Feral hogs, also referred to as feral swine, Eurasian or Russian wild boar, and wild pigs, are the same species Sus scofa. They are an aggressive invasive species introduced to the United States in the 1500s and have spread over most of the country in the last few decades (Gipson et al. 1998). Due to their unique life history feral hogs are a persevering ungulate species capable of causing extensive economical and ecological damage while causing a threat to human health and safety. They are considered one of the world’s worst invasive species (Lowe et al. 2000). Extinction of native species and loss of biodiversity due to this widely invasive species has been documented worldwide (Wolf and Conover 2003). This management plan describes the life history of feral hogs, the need for management in New York State, several action plans to address the need for management, and assessment protocol for each action plan. Also included in this plan is a grant request to fund the educational objectives in order to achieve more awareness and cooperation with the public, promoting higher probability of management success.

No Known Antidote: Quantification of a deadly toxin, tetrodotoxin, in red efts (Notopthalamus viridescens; Rafinesgue, 1820)

Mon, 04/29/2013 - 17:42
Abstract: Tetrodotoxin (TTX) in found in taxa worldwide including the eft life stage of the eastern newt (Notopthalamus virisdescens). Previous studies have shown that there is variability of TTX concentrations within efts and newts, and it is not known if the presence of TTX in these efts is common among populations. Our objective was to determine the distribution of TTX within the body N. viridescens efts. We hypothesized that the skin would have the highest concentrations of TTX as it is the area of the body that will likely come into contact with a predator. If certain regions of the skin come into contact with a predator more often than others, there may be significant differences in the dorsal, abdominal and pectoral regions of skin. Further, we hypothesized that the ova would have the second highest concentration of TTX as they are vital to reproduction yet vulnerable to predation. Through HPLC analysis we determined the concentrations of TTX within different tissues of N. viridescens efts including the: dorsal, pectoral, and abdominal skin; ovaries; testes; liver; pancreas; and alimentary canal. The concentrations of TTX between the different tissue types are not significantly different, nor were individuals significantly different in concentration of TTX from one another. Toxicity levels were high in comparison to other N. viridescens efts and more similar to the toxicity of highly toxic Taricha newts. The high toxicity of N. viridescens could be contributed to strong predation pressure by the slightly resistant garter snake (Thamnopsis sirtalis) and eastern hognose snake (Heterodon platirhinos).

The Conservation and Management of Wolverine (Gulo gulo) Populations in Northern Idaho to Help Prevent Human Caused Extirpation from the Contiguous United States

Thu, 05/02/2013 - 11:21
Abstract: Wolverines (Gulo gulo) were once a thriving species in the North Western United States, but large scale trapping and poison programs in the early 1900s lead to the species near extinction. Since then, populations in the United States have been struggling to maintain a strong presence in Idaho. Its current listing as threatened on the Endangered Species Act prohibits hunting and trapping, but more management is needed to sustain populations. Human development and recreation activities have caused wolverines to disperse from its nature range. Using habitat preservation techniques on current and historical wolverine habitat, increase availability and connectivity will improve dispersal. Close relationship with state officials will provide protection regarding land use, recreation, hunting, trapping and harassment. Public education will teach residents ways they can help prevent wolverine populations from further decline. Extensive research and population monitoring are needed due to the currently declining populations and the low fecundity of the species.

Paul Smith's College & International Learning: A Small Scale Assessment of Student Perceived Personal & Academic Gains

Mon, 04/22/2013 - 22:16
Abstract: Many students who participate in a study abroad experience during their college or university career experience positive gains on personal and academic levels. This growth can be gained directly from the sojourn while it is taking place, and/or upon individual reflection of the experience once the student returns home. Currently, Paul Smith’s College (PSC) students are able to participate in a variety of international experiences, including short-term (minimum of ten days) tours, faculty-led service learning practicums and semester-long study abroad programs, personally organized by individual students. Since there has been no central Paul Smith's College entity that examines how students may be making gains from these experiences, there exists an unmet need to discover how students believe they have benefited from study abroad. This study used grounded theory methodology and mixed qualitative research methods to investigate whether PSC students benefited personally and academically from their individual international learning experiences. This research has revealed the majority of students interviewed believed themselves to have been positively affected on both levels. These students are also more open to continuing traveling, either for personal enjoyment or career advancement. This perceived growth occurred despite, and perhaps, as a result of having experienced culture shock during their sojourns or upon their return to the U.S.

A COPAR Report of Ethnographic Inquiry Addressing Issues of Water Availability and Hygiene Mathare Valley, Nairobi, Kenya

Wed, 04/24/2013 - 21:30
Abstract: I conducted a cyclical ethnographic inquiry in the Mathare Valley informal settlement of Nairobi, Kenya, during the months of May and June 2012. My question was: How do Mathare residents interact with and access water and what are the technological and environmental restrictions limiting or preventing adequate water supply? The goal of this study was to create environmental and social change by improving access to water for consumption and bathing. As both a researcher and technical advisor, I adopted and used Community Oriented Participatory Action Research (COPAR). This research approach required my immersion into the Kenyan culture where I lived, ate and slept in the informal settlement of Mathare Valley, interviewing a total of 49 families on communal issues of water and hygiene. While in Mathare, I recorded quantitative and qualitative data comparing wet and dry seasons; distance to water sources; amount of water used; cost of water; and prevalence of disease (represented by potability) as well as issues regarding the Nairobi City Council, communal water availability, and hygienic conditions. A potential solution to water conservation and hygiene was construction of a bucket shower (several liter metal bucket with handle and valve to control water flow) to conserve bathing water reducing overall consumption. Through analysis of seven major, quantitatively and qualitatively determined themes, this paper presents anecdotal evidence in the context of empirical data through temporal revelation of thematic constraints. I found that during the dry season: family members in Mathare travel significantly farther to gather water, spending more money while consuming less water presenting complex issues among livelihoods within an informal settlement environment.

Remote Sensing for Forest Change Detection in Afghanistan

Fri, 04/26/2013 - 08:41
Abstract: Abstract: Afghanistan’s forests are one of the country’s most important natural resources. Afghanistan has faced conflicts that have plagued the country for more than 25 years and resulted in rapid deforestation and environmental despoliation. Forested lands need to be preserved in order for Afghanistan to revamp social and economic livelihoods and control the environmental degradation. This study will analyze Landsat satellite imagery using Geographic Information Systems (GIS) and ERDAS DeltaCue change detection software to assess forest deviations in Afghanistan between 1998 and 2010. Areas in Nangarhar Province identified significant change in vegetation cover in terms of both deforestation and reforestation. Deforestation occurred more frequently around the city edges of Jalalabad, whereas reforestation occurred farther from settlements. The Tasseled Cap process produced a final output change detection layer which represented the combined detection of all significant change between the three images. Determining where deforestation is occurring through Remote Sensing is a critical first step towards rehabilitating Afghanistan’s forest productivity.
