A Paleolimnological study of precipitation variability in the Adirondacks over the last thousand years

Mon, 12/02/2013 - 20:40
Abstract: At present, most regional climate models anticipate wetter conditions by the end of this century, but a few models anticipate drier conditions. This study uses foresight to test these models, as well as describe the relationship between the dominant climate system in the region and past precipitation in the Adirondacks. Precipitation was inferred from diatom assemblages observed along a lake sediment core extending into the 1000 years. This study shows that abrupt, extreme wet events were common during the last 1000 years, and a relationship between the dominant climate system (North Atlantic Oscillation) and precipitation was irregular during the cool Little Ice Age but negatively associated during the warm Medieval Climate Anomaly. With temperatures in the Northeast projected to increase by 2-5 degrees C by 2100 AD, our study suggests the region may become more arid rather than wetter, opposite of what models currently suggest.

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.

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.

Draft Horse Sustainability Presentations: The effectiveness of presentations on draft animal power at the Adirondack Rural Skills and Homesteading Festival

Fri, 12/06/2013 - 12:53
Abstract: Paul Smith’s College has been putting on draft horse presentations for the public for many years but until now it was unknown how effective these were in education of the audience in topics of the interest. During the 2013 Adirondack Rural Skills and Homesteading Festival, a series of demonstrations and presentations were conducted for the public. Surveys of those in attendance have now given us information on how far people are traveling, what their prior experience is, what they want to learn, and how they want to learn it. From this information we wish to gauge attendees’ response to draft animals and their uses.

Effects of Food Plots on (1) White-Tailed Deer (Odocoileus virginianus) Movement, (2) Antler Growth and (3) Potential Use by Other Wildlife on a Private 173 Acres in Davenport, NY

Mon, 12/02/2013 - 11:23
Abstract: In Davenport, New York, a 172.9 acre property is planning to undergo changes to suit a white-tailed deer management plan. This plan involves implementing four food plots of 4.25 acres, providing a year-long source of quality forage for the local deer herd, after initially clear-cutting 17 acres of forested land in spring 2012. Goals of food plot establishment are to supplement the value of the land as a hunting lease, increase viewing opportunities of deer, increase antler growth among bucks in the local deer herd, and to adequately supplement the diet of the local deer herd. This study focuses on the effects on (1) movement and (2) antler growth of white-tailed deer after the implementation of food plots on a forested property. Another component is the (3) potential for utilization of these food plots by other species of wildlife. Movement of deer will be assessed based on scat count, track count, and images of observed movement via trail cameras on travel routes. Deviation will be recorded from established travel routes, to new travel routes once the food plots have been implemented. The plot containing white clover showed the highest level of utility post-planting, followed by chicory, alfalfa and turnips.

The role of terrestrial leaf litter inputs on drift of aquatic invertebrate shredders

Mon, 12/02/2013 - 13:34
Abstract: This study examined the effect of food availability on active drift entry of aquatic invertebrates by comparing drift density at low and high levels of terrestrial leaf litter input in Alder Brook. An emphasis was placed on the proportion of shredders collected during each sampling, who rely most on coarse particulate organic matter as a food source. In order to quantify food available in the stream channel, leaf packs were collected along three transects and weighed to determine dry biomass per stream area. Invertebrate drift samples were collected at high (leaf abscission) and low levels (late summer) of food abundance using three surber nets spaced evenly across the stream channel. Samples were taken at 3-hr intervals over a 24-hr sampling period. Out of eight sampling periods, drift density at low litter input was found to be greatest just after sunset and through the evening hours. Drift densities were significantly higher during 2 sampling periods and numerically higher for an additional 4 sampling periods. Shredders did not comprise the greatest proportion of the drift at low litter input, only accounting for 0.4% of total drifting invertebrates. The proportion of shredders increased to 36.2% at high litter input.
