Potential Impacts of Road Salt Applications on Wetland Vegetation in Franklin County, NY

Thu, 07/07/2022 - 09:46
Abstract: With long winters in the Adirondacks, roadside environments are subjected to extended periods of potential pollution from road salt applications. Wetlands support a wide variety of endemic species that are sensitive to chemical alterations in the soil due to extensive road salt applications. This study focuses on the potential impacts that road salt applications have on wetland vegetation within Franklin County in the Adirondack Park of New York. Three sites were located on roads receiving minimal to no road salt applications. The other three sites were located on roads receiving high road salt applications. Each site had three transects evenly spaced, running perpendicular from the road, 100m into the wetland, with plots located at 0m, 50m, and 100m. Measuring percent cover of Obligate (OBL) wetland plant species, Facultative (FACW) wetland plant species, and total wetland plant species between sites, there was no significant difference between the two groups for the percent cover of wetland species. No significant difference was reported for pH values between the two groups. The high road salt sites had significantly higher electrical conductivity values. High road salt sites had a significantly higher plant species richness of OBL plants. No road salt sites had a significantly higher plant species richness of FACW plants. There was no significant difference reported in total wetland plant species richness (both OBL and FACW) between the two different site groups. Relying on only one years’ worth of data, this study serves as a baseline for future projects related to wetland vegetation and road salt applications.

Paleoecological Study of Heart Lake in the High Peaks Region.

Thu, 07/07/2022 - 10:01
Abstract: Paleoecological techniques were used to reconstruct long-term changes in the watershed of Heart Lake in the High Peaks region of the Adirondacks Mountains of New York State. The primary sampling was for diatoms, “glassy” photosynthetic algae, that could provide long-term perspectives on ecological processes. The reconstruction of the chemical and biological history with various diatom species provides evidence of watershed acidification and productivity (aquatic systems health) throughout the past to recent time scales. A UWITECH gravity core was used to sample sediment in two of the deepest holes. As evident with diatom species taxa, Heart Lake may have experienced acidification that was interrupted by the effects of forest fire in the watershed. The lake became more productive in the last few decades following amendments to the Clean Air Act in 1990 and other anthropogenic effects. The disturbances to the watershed contradicted the “heritage” status of Heart Lake with variability in diatomic and fish communities, moving away from pristine and towards disturbed.

The Ecology of Freshwater Sponges in the Headwaters of the St. Regis River

Thu, 07/07/2022 - 11:16
Abstract: Various ecological aspects of the marine sponges are well-known. However, sponges inhabiting freshwaters have been largely ignored despite having widespread distribution and possibly being water quality indicators. Basic information about their abundance, biomass, and preferred habitat remains unclear. Biomass of sponges in the headwaters of the St. Regis River was estimated to determine if they require certain habitat features. Data collection occurred before dormancy in autumn to acquire an accurate estimation of biomass. The average biomass for the entire study was 3.04 dry g/m2. Percent cover was visually estimated and recorded as a second measurement of freshwater sponge abundance. According to this scale, sponges were rare (<5%), occasional (6 to 15%) or present (16 to 25%) across the three study reaches. Freshwater sponges were found in velocities of 0 ft/sec to 2.4 ft/sec. Most freshwater sponges were found on submerged, large cobble (64 – 255 mm) and pebbles (2 - 64 mm). Despite this, percent cover, velocity, substrate type and percent canopy openness had no significant relationship with the biomass of freshwater sponges. Additionally, depth of the water and freshwater sponge biomass had a weak significant relationship. Keywords: freshwater sponges, ecology, distribution, habitat features, biomass

The Lawns at Paul Smith’s College: The Effects of Mowing on Root Biomass and Soil Compaction

Mon, 12/07/2020 - 17:41
Abstract: Lawns are a valuable aspect of real estate in the United States. Maintained lawns cover over 163,000 square kilometers of land, yet few people realize the impact mowing can have on the ecosystem. This study will be looking at the impact of mowing on the grassland ecosystem and the terrain grassland ecosystem at Paul Smith’s College, located in Paul Smiths, New York. This study will be testing two different factors that are impacted by constant mowing on campus: soil compaction and root biomass of flora found on the sites. Soil compaction is the compression of soil due to large amounts of pressure placed on the surface soil. This event will be tested by using a soil bulk density test. The root biomass is being investigated by the use of a scale to weigh root given from each area of the study site. The study goal is to find out how the disturbances of mowing affect the grassland ecosystem found at Paul Smith’s College using two different factors: soil compaction, root biomass. The results of the study show the site type that has the greatest soil bulk density and the lowest dry root biomass in G/〖cm〗^3 is the dry slope site on the campus.

Small Mammal Presence and Predation of Boreal Bird Nests in Forested vs. Open Peatlands in the Northern Adirondack Park, NY

Mon, 11/30/2020 - 16:07
Abstract: Recent declines of many boreal birds have been documented in the last decade and area attributed to changing climate and human development. One factor that has not been studied in the critical boreal peatland habitats in the Adirondack Park is the occurrence and influence of small mammals preying on passerine boreal bird nests. The hypotheses tested were (1) small mammals occupy forested peatlands in a higher abundance than open peatlands at the study sites and (2) boreal bird nests in forested peatlands are more likely to be preyed on by small mammals than nests in open peatlands. Baited track tubes were placed on transects within open and forested peatlands and activity was estimated from prints left on contact paper, and artificial nests and eggs were used to compare the difference in nest predation between open and forested peatlands. There was a difference in small mammal activity between forested and open bog at the Paul Smith’s VIC study area, but results were not significant at Shingle Shanty medium bog. 67% of artificial nests in the forested bog at the VIC were destroyed, and only 14% were destroyed in the open bog. At Shingle Shanty, 83% of the nests were destroyed in the forested bog and 0% of artificial nests were damaged in the open bog.

Distribution and Abundance of Larval Yellow Perch (Perca flavescens) in Lake St. Clair and the Lower St. Clair River, 2018

Mon, 12/02/2019 - 21:23
Abstract: Spatial and temporal dynamics of fish larvae play an important role in determining year-class strength due to variation in habitat quality and food resources that influence larval growth, development, and survival rates. Surveys conducted during the past decade in the St. Clair-Detroit River System have revealed a decline of yellow perch. Genetic and microchemistry analyses showed that these fish make a substantial contribution to the yellow perch stock in western Lake Erie. Our study examines the spatial and temporal distributions of larval yellow perch in Lake St. Clair and the lower St. Clair River to identify important spawning and nursery areas and other ecological factors influencing their early life history. We employed a lake-wide daytime sampling program in 2018 using paired bongo nets to sample pelagic larvae throughout 33 sample locations beginning in mid-March before yellow perch had hatched and continued through mid-July when larvae were absent from samples. Based on our spatial analysis results, Mitchell Bay and Anchor Bay appear as the primary regions for yellow perch spawning habitat and/or nursery grounds for larvae. It is difficult to conclude which factors are influencing the distribution of yellow perch the greatest, but submerged aquatic vegetation, water temperature and clarity likely influence yellow perch vital rates, based on our study. The results from this study give us a growing understanding of the ecological interactions underlying larval yellow perch and their habitat usage during their early life history.

Lower St. Regis Lake Survey: A Comparative Study of Fish Population Structure and Function over Time

Thu, 12/13/2018 - 14:24
Abstract: Lake surveys are performed on bodies of water to provide a health analysis of fish populations over time. Lake surveys can be conducted in a variety of ways to attain specific data. Lower St. Regis Lake was surveyed to determine the fish community composition and to understand fish population traits. Using fyke nets placed at six predetermined locations for 24 hours, as well as fishing, we collected data for age, length (mm), weight (g), and parasites present. Data was analyzed in the lab using Excel to form graphs and tables to demonstrate our findings. Catch rates were lower compared to years before and comparing our data to New York State Department of Conservation data found that our length-at-age data was lower for the six-species sampled. Pumpkinseed and yellow perch were the only two species to have over twenty fish sampled. Decreased air temperatures brought in by a cold front during the week of our sampling may have been a reason for our lower number of fish caught. Mesh size is also a bias while using these nets as smaller fish can escape, and predatory fish can prey on smaller fish while in the net. Some species of fish such as black crappie may be more susceptible to capture due to its habit of associating with structure.

Paul Smith’s College Shoreline Restoration Conservation Plan

Fri, 12/14/2018 - 12:24
Abstract: A restoration plan was created for the Lower St Regis Lake shoreline of Paul Smith's College. To date, about 140 students have participated by way of studies and course work in surveys and assessments, which clearly indicate a much reduced level of biological diversity, ecosystem function, and human uses compared to other sites. The plan is designed based upon field assessments and with the intentions of using the shoreline as an on-site case study of experiential education – a tradition of at the core of Paul Smith’s College. The aim of the restoration plan is to increase biodiversity, ecosystem function, aesthetics, educational studies, and shoreline use.

Wetland X: Wetland Mitigation Plan Amendment

Mon, 12/03/2018 - 17:56
Abstract: Wetland X is a wetland that is located in Western New York and has been converted to agricultural land. The goal of this study was to create a restoration plan for Wetland X that meets Natural Resource Conservation Service (NRCS) standards. The study took place during June 2018 with the final plan being completed in August of 2018 and the data analysis report being completed in the fall of 2018. The focus of the study was on the woody vegetation of the site to document the species present and the density of vegetation on the site. Vegetation was sampled on four plots located at different areas of the site to provide the best representation of the sites overall conditions. The areas were sampled using zigzag transects and grid transect patterns; with one area being sampled using the zigzag pattern, two using the grid pattern and one using both transect methods as a comparison of the two methods. Sampling of the site found that an amendment was needed for Wetland X to ensure that the landowner remained in compliance with the Food Security Act Standards. The restoration plan focuses on planting and management techniques for the site that will allow proper growth of desired vegetation species and the eradication of the invasive species. The created restoration plan amendment has been implemented and will be completed by June of 2019 with five years of monitoring following completion.
