Management Plan to Increase Nesting Success of Northern Pintails (Anas acuta) in the Prairie Pothole Region of North Dakota

Mon, 05/07/2018 - 17:36
Abstract: Once one of the most abundant ducks in North America, northern pintails have significantly declined since the 1960s when populations reached about 10 million. Over the past 40 years they have declined 78%, or about 2.4% per year between 1966 and 2015, due to expanding agricultural activity in their prairie pothole breeding grounds. In 2009 that the pintail population was estimated at 3.2 million, which is substantially below the 5.6 million population goal set by the North American Waterfowl Management Plan. The northern pintail population is substantially impacted by drought; and a loss of grasslands and wetland habitat in the prairie pothole region. Without proper breeding habitat pintails migrate further north to the Artic lowland tundra, where wetland conditions are more stable. However, when large numbers breed in these regions fewer young are produced. As a result, the prairies are where the fate of the pintail population lies. Throughout North America the northern pintail is listed as a migratory bird species where it is protected under the Migratory Bird Treaty Act and receives some management under the North American Waterfowl Management Plan. In North Dakota, the northern pintail is listed as a level II species of concern and there it receives management under the State Wildlife Action Plan, but because it is only a level II species it does not receive the management until all actions are covered for level I species. However, due to the species large geographic range and large worldwide population estimate it is listed as a species of Least Concern with a declining population on the International Union for Conservation of Species (IUCN) Red List of threatened species. The goals of this plan are to increase the abundance and distribution of northern pintails in North Dakota over the next 10 years and to provide information that leads to greater public involvement for the management of the species in North Dakota. The objectives to achieve these goals include: mitigation of agricultural impacts on nests, reductions of egg, hatchling, and hen predation via predator exclusion, increase in nesting habitat via Farm Bill practices and State Wildlife Grants, and the education of the public about the nesting requirements of northern pintails and the potential impacts of agriculture as well management practices to avoid these impacts. Based on population modeling, egg, hatchling, and hen survival is the key factor to focus on when managing for this species. An increase of about 50% nest success (eggs) and reduced predation rate on hatchlings and hens should result in a positive population trend, yielding a population of 6.7 million in 10 years, with a greater than 50% increase being more favorable to the overall goals and objectives. Northern pintails are a game species that needs management action in breeding areas to ensure their survival and growth for the enjoyment of current and future generations.

Special Topic: An Investigation of Long Term Monitoring of Fishes in Two Aquatic Ecosystems

Fri, 05/11/2018 - 10:06
Abstract: Lower St. Regis Lake Abstract Long-term ecological research is important in understanding how fish communities change over time. The objective of this study was to determine how fish communities in Lower St. Regis Lake have changed. From 2004 - 2017 fisheries students at Paul Smith’s College have conducted lake surveys on Lower St. Regis Lake using standardized sampling protocols. This study showed shifts in fish community composition, changes in size structure, and variable body condition. As Lower St. Regis Lake changes, continued long-term ecological research will provide an opportunity for students monitor and study factors that may be effecting fish populations and communities. Smitty Creek Abstract Long term ecological monitoring of streams provides an effective means to evaluate changing habitat conditions on fish population dynamics. Our objective was to use long-term data from four tributaries in Smitty Creek Watershed to explore the relationship of age-0 brook trout densities to regional weather conditions. Catch data of age 0 brook trout was collected during the fall from 2004 to 2017. Average monthly precipitation and temperature data was taken from the Lake Clear regional weather station. Of four streams, Little Aldo showed correlation of age-0 brook trout with the precipitation and temperature data. Future work should include improved instrumentation within the reaches and the use of site-specific data.

A study of how different liquids affect the fermentation process in breads.

Sun, 05/07/2017 - 14:41
Abstract: We all know that different liquids have different densities and will affect any product you are making in a unique way than the other. But how exactly do different liquids affect the fermentation of yeast in a bread dough. In this paper, I will go on to tell you about five different liquids and the type of bread I chose to use for the trials. I will also go into why I chose that type of bread and touch on the history of it.

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.

Comparison of Fine and Coarse Organic Matter Among Levels of Shoreline Impact: Implications for Ecological Restoration

Mon, 05/01/2017 - 15:24
Abstract: Human lake shoreline development has been shown to have impacts on the dynamics of the lakeshore. Such dynamics include the riparian and littoral zones interactions; the complexity, abundance, and residence time of large woody debris; organic matter/detritus, and food webs for fish, birds, and macroinvertebrates. Understanding such dynamics, and the impacts of human development, are important when attempting to restore the shoreline through the process of ecological restoration. The objectives of the study were, (1) to compare the amount of organic matter (smaller than sticks, branches, logs, and trees) among three levels of impact (impacted, minimally impacted, and benchmark), (2) to compare the amounts of CPOM and FPOM among the three levels of impact. The field data was collected using a modified design of sediment corer. A total of 63 samples were taken and the results clearly showed that the reference (benchmark) site had a much higher accumulation of organic sediment along the shoreline. Also, the data analysis also showed that there was virtually no measurable FPOM among the impacted and minimally impacted sites, but among the references sites it was more abundant than CPOM, which was opposite from the impacted and minimally impacted sites.

A Comparison of Leaf Litter in the Aquatic, Terrestrial, and Transitional Zones among Impacted, Minimally Impacted, and Benchmark Conditions of the Shorelines of the Lower St. Regis Lake and Black Pond

Mon, 05/01/2017 - 17:55
Abstract: Human development of shorelines impacts structure and functionality of the shoreline’s ecosystems. Ecological restoration projects can be used to rectify this impact, but first data must be collected to determine the extent of impact human development has had on the shoreline. The objective of this study was to compare the biomass (wet and dry weights) of deciduous and coniferous leaf litter among impacted, minimally impacted, and benchmark shorelines and between terrestrial and aquatic zones. Data was collected among the three impact levels on the Paul Smith’s College property along the shores of Lower St. Regis Lake (impacted and minimally impacted) and Black Pond (benchmark). Deciduous and coniferous leaf litter was collected in the aquatic and terrestrial zones of the shoreline and among the three impact levels using 0.7 m2 terrestrial and 0.25 m2 aquatic quadrats, and then compared using nonparametric statistical tests to determine differences among impact levels and between zones. The results of this study revealed that the relationship between deciduous and coniferous leaf litter was more nuanced than expected. The study supported the current body of scientific knowledge in that shoreline development decreases the overall amount of leaf litter accumulated in the shoreline of lakes. However, should future studies on variation between deciduous and coniferous leaf litter be conducted, the criteria for impact levels should be expanded to ensure the sites used are more comparable in forest type.
