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.

Developing A Wildlife Teaching Collection

Wed, 12/06/2017 - 13:14
Abstract: Wildlife specimens hold significant scientific and educational value at Paul Smith’s College through the preservation of essential biological information. Specimens allow for the better understanding of the past and present conditions of a species, and are a valuable teaching tool for all-inclusive wildlife education. However important, it is apparent that the accumulation of wildlife specimens is insufficient due to a lack of education surrounding the preservation of specimens and methods pertaining to the development of a specimen collection. In response, the procedural framework surrounding standard specimen preparation practices was analyzed and adjusted in order meet the specific needs of the institution. A comprehensive procedural manual was created with the intention of making specimen preparation a more approachable task for interested students, as well as to ensure continual growth of the wildlife teaching collection at Paul Smith’s College.

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.

Creating Universal Use for the Glenview Preserve

Fri, 12/15/2017 - 20:40
Abstract: The Adirondack Land Trust recently purchased 238 acres along Route 86 in Harrietstown. This tract of land is called the Glenview Preserve. The Adirondack Park Agency has already designated a scenic vista of Whiteface Mountain and the High Peaks. Along the back of the property is the Bloomingdale Bog, which is the third largest boreal peatland in New York. Vista like the Glenview Preserve, which doesn’t involve a climb and is also accessible to all. This poses the perfect opportunity to establish universal trails for all to enjoy. Conservation of land is made possible by connections that people make to the land. If there is no connection to nature, it could be destroyed without anyone speaking up. The location of this tract of land makes it ideal for accessible trail since there is no mountain to hike to get the view. Hiking is one of the oldest pastimes of the world. People can experience beauty every season of the year. It strengthens our bodies and minds at no cost. Hiking is a wonderful chance to feel the earth below your feet and get up close and personal with nature. Installing trails would not only open up recreational opportunities such as hiking, running, and bird watching, skiing and snowshoeing but also build community.

Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.
