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.

Assessment of Tree Planting Riparian Management along the Ausable and Boquet Rivers in New York State

Tue, 12/05/2017 - 14:28
Abstract: Ecological restoration is, in part, restoring degraded ecosystems. By adding riparian vegetation along degraded reaches of rivers and streams, ecologists can begin to restore the natural habitat and processes associated with that river or stream. Trees, shrubs and grasses can be very important in retaining stream bank soils, providing shade in the river and habitat for terrestrial species. Two programs called Trees for Tribs and Ausable River Association (AsRA), restore degraded riparian areas in the state of New York, including the Ausable and Bouquet Rivers in the Adirondack State Park. This study compared survival rates of the plantings in nine different locations along the Ausable River and one location along the Boquet River. The tree species, living status (survivorship), and stem density of the understory was recorded. The four AsRA planting sites and one U.S. Fish and Wildlife Service site planted saplings ranging from 6-8 feet in height, and the Trees for Tribs planted seedlings at the other five sites. It was found that there was no significant difference between the survival rates of the saplings in comparison to the survival rates of the seedlings (p-value = 0.37). In addition, there was no significant difference (p-value = 0.05) in the stem density measurements between sapling and seedling plots. It was also observed that records of tree plantings were either missing, incomplete or inaccurate from both Ausable River Association and Trees for Tribs.

Living Machine ® Wastewater Treatment in Sólheimar

Tue, 12/05/2017 - 15:02
Abstract: As of 2014, Sólheimar Ecovillage in South Iceland began to experience inadequate sewage treatment. After a large earthquake, the community’s constructed wetland became damaged, freely expelling untreated wastewater into the surrounding watershed. After research, the Living Machine® system became the evident solution to help mitigate this issue. By using a case study of a Living Machine® system in South Burlington, Vermont, I was able to determine output estimates of individuals by gallons per day (GPD) and approximate a price for a Living Machine® with a greenhouse at $1,019, 694 USD. Different approaches Sólheimar could take to help make this project successful would be installing a flowmeter, applying for different grants, charging tourists to use the restrooms, and contacting the engineering company to discuss the current and future piping system in the village.

A Comparison of Fall and Spring Minnow (Cyprinidae) Surveys to Assess Overwinter Changes in Community Composition in a Marshland of the Northern Adirondacks, NY

Wed, 12/06/2017 - 03:51
Abstract: Minnows are an integral component of a healthy aquatic ecosystem. However, minnows are very sensitive to habitat destruction and loss, changes in water quality, and over predation. As a result of its integral role, an unhealthy, or absent minnow population can wreak havoc on an ecosystem. The objectives are to compare minnow species richness and composition between spring and fall surveys for different regions in the marsh, compare minnow trap catch rates between fall and spring for each minnow species for different regions of the marsh, compare mean length of minnow species between fall and spring, and compare water temperature, dissolved oxygen, pH, and conductivity in the fall with that of late winter and post ice-out. The study location was Heron Marsh of New York’s Adirondack Park, which supports of variety of fish in the cyprinidae family. Water quality was collected using a YSI meter in all 4 seasons of the year, and minnows were sampled using galvanized steel minnow traps during the fall and spring. Nearly all sites saw an increase in cyprinid biodiversity and abundance. Long term monitoring should be established for more robust data that can in turn justify more solid conclusions.

The Effects of pH on the Distribution of the Mink Frog (Lithobates septentrionalis)

Fri, 12/08/2017 - 14:41
Abstract: Amphibian decline is occurring at an alarming rate. The acidification of aquatic systems is contributing to the decline, affecting habitat viability which affects dispersal, breeding success and the mortality of young. Tolerances to the acidic conditions vary amongst species, but are not known for all amphibians. The mink frog (Lithobates septentrionalis) has scattered dispersals throughout the regions in which they are found. The goal of this study was to observe possible effects of pH on the distribution of the mink frog, which is native to the Adirondack Park. A call survey was completed in 40 Adirondack water systems to determine dispersal. The pH of the lakes in which the call survey was conducted were also recorded. This study documents the relationship between pH and distribution of the mink frog along with the variations between the lacustrine and deep water pH values for each water system. The mink frog was not found in lakes with pH <6.5. Evidence also showed that the pH between deep water and lacustrine regions had varying differences that may prove to be significant in regards to studying some species. It is recommended that lacustrine data be examined along with limnologic deep water data when studying lacustrine dwelling species.

Does the presence of Malus spp. increase the fertility of the soil surface in pastures?

Mon, 05/01/2017 - 18:24
Abstract: Techniques to increase soil fertility in a pasture can benefit the system by combating soil degradation and increasing the health of vegetation. The use of apple trees (Malus spp.) may be particularly beneficial in achieving this due to reliable fruit yields, ease of management, and variety of suitable habitat. We hypothesized that soil directly under the canopy of apple trees would be higher in nutrients (C, Ca, K, Mg, N, & P) than soil in areas with no tree cover. Soil samples were taken from the top 15 cm of the soil surface under apple trees and in areas without trees at 14 sites in Massachusetts and New York. Samples were analyzed using spectrometry and color imagery to determine nutrient content. Potassium and magnesium concentrations were found to be significantly higher in under-canopy samples. Further research may expand these results and determine if the application of apple trees can be used to increase the health of pasture systems.

The Age and Origin of Lake Ejagham, Cameroon: 9,000-Year-Old Sediment Evidence Suggests Possible Bolide Impactor

Tue, 05/02/2017 - 15:18
Abstract: Lake Ejagham is a relatively small lake (54 hectares) located in the south-western region of Cameroon, Africa. Two sediment cores, EJ1 and EJ2, were extruded in 1987 by Dr. Dan Livingstone, preserved, and analyzed in 2016. Sediment and diatom analyses were performed in conjunction with radiocarbon dating, which suggests the maximum age of the lake itself is about 9,000 years old. The age of the lake was confirmed by both the radiocarbon dating of the sediment as well as the dating of wood fragments found at the base of the EJ2 core. The diatom analyses indicate that in recent times high percentages of planktonic diatoms were present, which suggests a relatively wetter hydroclimate than in the past. In the mid-section of EJ1 those planktonic diatom percentages were lower, which indicates drier climates or changes to the lacustrine environment. The consistency in the sediment and climate record suggest that Lake Ejagham has been uninterrupted by environmental catastrophes, which provided suitable conditions for endemic cichlids to evolve via sympatry, particularly Coptodon ejagham. Lake Ejagham has been thought to have formed as a solution basin, when water dissolves and carries away underground minerals forming a depression. Instead, the bedrock beneath the lake contains both soluble and insoluble layers, which prevent this from happening. Here we assert that the EJ1 and EJ2 cores support an alternative origin, possibly from a bolide impactor, however this is not conclusive.

Affordable Sustainable Housing in the Urban Environment

Sat, 05/06/2017 - 21:26
Abstract: This paper addresses the lack of sustainable affordable housing in the urban environment. The focus of this study is the urban environment due to an increased rate of migration from rural areas to urban areas. This increase has led to a growing need for cities to become more sustainable in order to support the increasing population density. Focusing on the residential sector, cities have made great strides towards providing green-supportive and sustainable housing for their residents. However, the accessibility to sustainable housing in the urban environment for low-income residents is limited. The primary research questions this study addresses are what are the barriers to sustainable affordable housing in the urban environment, and how can we overcome these barriers? Through using secondary sources, the findings for this study were that the greatest barriers to developing sustainable low-income housing is the need for costly retrofits, and a lack of government subsidies. Addressing the second research question, the solutions to overcoming these barriers include: technological innovation, public-private partnerships, encouraging grass-roots groups, mixed-use development, and micro-apartments.
