Lyme Disease in the Adirondacks: Using Domestic Canines as Sentinels for Human Risk

Tue, 12/05/2017 - 14:46
Abstract: Lyme disease (Borrelia burgdorferi) is the most prevalent zoonotic disease in the United States. With an increase of cases every year in new areas, it is crucial that researchers and veterinarians use sentinels, such as canines, to determine the prevalence of Lyme disease in emerging areas where tick density may be low. The main objective of this study was to determine the annual infection rate of Lyme disease in canines in Franklin and Essex County. An immunologic assay was performed to determine percent of canines exposed to Lyme bacteria as well as timing of exposure. Thirty-four random blood samples were collected from a local veterinary office during routine health screenings, and analyzed for Borrelia burgdorferi antibodies. Out of the thirty-four samples, two canines were positive for OspC antibodies (indicator of early infection) and three were positive for OspF (indicator of chronic infection). The annual infection rate for the 2017 year was 5.9%.

Riparian log gardens: examination of vascular plant communities and moss on logs in waterbodies

Tue, 12/05/2017 - 19:51
Abstract: Microsites can play a major part in facilitating plant diversity. Specific physical characteristics of microsites can create favorable conditions for certain species by isolating them from competition or protecting them from herbivory. Plant communities and woody debris can also facilitate the growth of other plants. I examined relationships between moss and vascular plants on log gardens in waterbodies to determine correlations between these organisms. I hypothesized that riparian log gardens, large woody debris in lakes and ponds supporting mats of terrestrial vegetation, serve as sites that may harbor rare species or have high plant species diversity. I also examined the relationship between bryophytes and plant communities based on the idea that bryophytes influence microsite characteristics. Knowing where rare species are harbored and what microsites encourage high diversity are important for preserving species. I surveyed plants on large woody debris in lakes and ponds in the northern Adirondacks and calculated the richness and diversity of the communities in relation to the presence of mosses. I found that logs that supported moss mats had more plants. The mean species richness of the riparian log gardens was 8.6 for all plants and 6.3 for herbaceous species. Some significant positive correlations were found for log area, log hardness, mat area, mat depth, and vascular plant diversity.

A Comparison of Macro-Invertebrate Communities in Different Substrates among Impacted and Minimally-Impacted Sites on Lower St. Regis Lake and Benchmark Sites on Black Pond

Wed, 05/03/2017 - 21:34
Abstract: Many shorelines today have been impacted by human activities which has resulted in changes in macro-aquatic invertebrate communities. Ecological restoration can be used in efforts to bring macro-aquatic invertebrates back into shorelines. However, data is needed to better understand how macro-aquatic invertebrates can be used in these efforts as indicator species to determine community structure health and function. This project compared the macro-aquatic invertebrate communities in impacted and minimally impacted sites located on Lower St. Regis Lake and benchmark sites located on Black Pond. The two objectives to this project were to 1) compare the species richness among impact levels and 2) compare the density among impact levels. Each impacted level has three sites and at each site ten samples were taken in a systematic way which resulted in 90 total samples. Samples were taken to the lab to be sorted and for macro-aquatic invertebrates could be identified to the family level. The macro-aquatic invertebrate community was different among each impact level. The overall family diversity was greater at the benchmark sites than the minimally impacted and impacted sites. Dominate substrate type that had a greater presence of different families were sites that had organic matter. The findings of this study create a more knowledge base which can be useful for future ecological restoration efforts on the impacted and minimally impacted areas located on Lower St. Regis Lake and to educate the public on the impacts on macro-aquatic invertebrates and their communities.

A Taste of Tea

Thu, 11/30/2017 - 14:49
Abstract: Originating in Southeast China, tea is one of the most consumed beverages in the world, second only to water with coffee in third. Though tea has many names, they all come from the same plant, Camellia sinensis. There’s white, yellow, green, oolong, pu-erh, and black or red tea; each has its own variants and processing methods to distinguish them. Tea has spread throughout the world and each culture took these leaves and made it their own in different ways. The journey it has taken is an interesting one with a lot of controversy, conflict, and corruption once introduced to the British Empire.

The Effects on Soil Caused by Garlic Mustard (Alliaria petiolata) in a Northern Hardwood Forest in the Northern Adirondack Mountains

Mon, 12/02/2013 - 10:54
Abstract: Plant invasions are thought to be among the worst causes of biological extinction and biodiversity loss in the modern world. With the United States spending upward of thirty four million dollars a year in attempts to control and repair the damages caused by invasive plants, not only are we feeling the biological effects, but we financially cannot afford to keep combating these invasive species (Barto and Cipollini, 2009). Garlic mustard (Alliaria petiolata) can invade multiple types of sites whether the soil is sandy or if a site has been disturbed. This invasive species will take over the understory and alter soil chemistry (Morris, McClain, Anderson and McConnaughay, 2012). This study aimed to look at how garlic mustard is affecting soils in the northern Adirondack Mountains in New York State. Although currently scattered and not very prevalent, there have already been changes to the soil chemistry. This study was conducted by setting up multiple plots within areas where garlic mustard was present and gathering soil to be used to test for nutrient values. It was found in this study that calcium, phosphorous, magnesium, potassium, sodium, aluminum and soil pH values changed due to the presence of garlic mustard.

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.

Compaction of Hiking Trails Located in the Northeastern Area of the Adirondack State Park, New York

Mon, 04/29/2013 - 12:19
Abstract: With continued increases in outdoor recreation in the United States, the physical impact of that use needs to be monitored for its effects. The purpose of this study was to explore whether a relationship exists between traffic numbers and soil strength of trails in the High Peaks Region of New York’s Adirondack state park. Soil strength was used as a measure of compaction because of its ability to indicate certain aspects of soil physical properties like bulk density, and hydrological condition (Mirreh & Ketcheson,1972), which are also soil physical properties that are effected by compaction (Hanna & Al-Kaisi,2009). These physical properties are important factors which influence a soils ability to carry out its biotic and abiotic processes (Kozlowski,1999). Initially the relationship between average soil strength of trails and traffic was insignificant. Upon further analyzing the data we found a significant relationship between on-trail and off-trail soil strength and used this relationship to create on-trail residual soil strengths. This was done to remove the influence that off-trail soil strength was having on the traffic vs. soil strength relationship. With the on/off-trail relationship influence removed, the relationship between on-trail residual soil strength and traffic was significantly improved. Literature discussed showed how the soil strengths collected could be used to infer possible effects on the sites tested. Relations between soil strength and bulk density, root elongation, root penetration, and trail recovery were all reviewed to provide insight on the quality of the soil at sample sites.

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).
