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.

An Educational Assessment of a Nature Center

Wed, 12/04/2013 - 15:18
Abstract: Currently, there is a strong focus on public environmental education. However, it is not known how environmental education programs relate to the New York State Curricula or to the North American Association for Environmental Education’s (NAAEE) education goals for school-aged children. The purpose of this qualitative, relationship study is to determine how and to what extent a nature center’s educational programs relate to New York State Curricula and the North American Association for Environmental Education’s education goals for school aged children. Data will be collected through a content analysis approach. The information gathered from the content analysis will then be compared against each other to see where there are gaps in the nature center’s educational goals and how they might ameliorate them. This information can be used by the nature center to format their educational programs in a way that is more conducive with both the New York State Curricula and the NAAEE educational goals.

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.
