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.

A Comparison of Winter Wildlife Use of Minimally, Moderately and Highly Impacted Shorelines on Lower St. Regis Lake and Black Pond in the Adirondack Park, NY

Wed, 05/09/2018 - 10:51
Abstract: Continued development and human interference with freshwater shorelines creates a degraded environment and can negatively affect native wildlife along impacted areas. Throughout the Adirondack Park, shorelines have experienced substantial degradation with the development of lakeside summer homes. There tends to be a strong preference for the aesthetics that lakes offer, as well as the numerous recreational opportunities they provide. The increased human use of shorelines and the development of anthropogenic structures has directly resulted in the degradation of shorelines in the Adirondack Park. Likewise, the Paul Smith’s College shoreline along Lower St. Regis Lake has been subjected to degradation throughout the history of the campus. This highly impacted site was selected, alongside minimally and moderately impacted sites in the surrounding areas as representatives for different impact levels. Shoreline degradation includes a decline in the health and presence of natural vegetation, creating a decrease in available food source for native wildlife. The removal of natural vegetation creates a decline in shoreline stability with the removal of root systems, allowing for greater amounts of erosion to occur. Additionally, degradation decreases available canopy cover and increases exposure of wildlife to predation. The objective of this study was to determine the difference in wildlife activity and diversity between three levels of shoreline impacts: minimal, moderate, and high. It was expected that the minimally and moderately impacted shoreline sites would show a greater diversity and abundance of wildlife than highly impacted shorelines. Trail camera data was analyzed at three sites for each treatment on Paul Smith’s College property, along both the Lower St. Regis Lake and Black Pond. Although we detected no significant differences in either activity or diversity across the treatments, there was higher relative activity and diversity in moderately impacted shorelines than minimally or highly impacted. However, wildlife species that are more rare and/or area-sensitive, such as the fisher (Martes pennanti) and American marten (Martes americana), were only detected in the minimally impacted shorelines of Black Pond. A restoration of the highly impacted shoreline to reflect minimally and non-impacted shorelines of the surrounding region would allow for opportunities to improve habitat for native wildlife species.

Effects of Silvicultural Treatments on Wildlife Communities at the Paul Smith's College Forest Research Demonstration Areas

Fri, 05/11/2018 - 16:15
Abstract: Logging has drastically altered North American forest ecosystems for centuries. While extensive studies have been done to determine the impacts of different silvicultural practices on plant communities, minimal research has evaluated the impacts on wildlife communities, particularly in the Adirondack Mountains. Silvicultural practices may significantly impact wildlife communities due to the disturbances it causes, as well as the way it alters the habitat. We monitored winter wildlife communities in the Forest Ecosystem Research Demonstration Area owned by Paul Smith’s College in the Northern Adirondack Park. By analyzing the data collected by trail cameras, tracks and measuring percent browse, we compared the abundance and diversity of wildlife in three silvicultural treatments (i.e., clearcut, group selection, control). We also collected data regarding the physical aspects of the silvicultural treatment plot (i.e. canopy cover and snow depth) to indicate the kind of available habitat. We found that despite there being the highest average relative activity in group selection, there is no significant relationship between average relative activity and harvest treatment type. Using the Shannon-Weiner Diversity Index, we found that the highest diversity was in control/reference. Due to our limited treatment sample size, we did not have conclusive findings in most areas of our study. However, the highest total tracks and relative activity were found in the clearcuts. We suggest that more research be done on this study in order to eventually make forest management plans that properly account for both plant and wildlife species.

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.

Analysis of Forage Quality in Adirondack Macrophytes: Implications for Waterfowl Nutrition

Fri, 04/29/2016 - 14:48
Abstract: To understand the relative nutritional value of macrophyte food sources for Adirondack waterfowl, the forage quality of four common Adirondack macrophytes were assessed. An analysis of two native pondweeds (Potamogeton) and two invasive watermilfoil (Myriophyllum) was conducted to deduce how invasive and native macrophytes compare in their relative concentrations of nitrogen and mineral content; important indicators of forage quality for waterfowl. Nitrogen content is used as a metric for relative concentration of protein. Macrophyte species were sampled from four Adirondack lakes of the same trophic status to account for effects of lake nutrient characteristics on plant nutrient uptake and synthesis. Total nitrogen was determined with the Kjeldahl procedure using flow injection analysis. Ash (mineral) content was acquired through high-heat burning in a muffle furnace. The invasive watermilfoil species had a higher percentage of nitrogen than the native species. There was no significant difference in the ash content between the species. It is critical to understand the ecological function of these species in relation to wildlife populations. The nutritional value of these aquatic macrophytes may have implications for the fitness and distribution of breeding herbivorous waterfowl in Adirondack lakes. These results may indicate that invasive plants will serve as a viable food source for herbivorous waterfowl as watermilfoil continues to spread across Adirondack aquatic systems.

Walden Pond: Ecological and Anthropological History Reflected in the Sedimentary Record

Tue, 05/03/2016 - 23:13
Abstract: This study examined environmental changes reflected in the microfossil record of a sediment core taken in August 2015 from Walden Pond, Massachusetts spanning the last 600 years. In particular changes in the eutrophication status, inorganic sediment deposition due to land use, lake water depth and temperature were examined using phytoplankton indicator species—diatoms and chrysophytes— to reconstruct environmental conditions. The study site was a basin shallower and closer to the source of anthropogenic N and P inputs than the site of previous studies at Walden’s deepest basin, allowing for finer detection of changes in water level and organic content of sediment. A gravity corer was used to collect the sediment core to preserve topmost sediment layers for analysis, as more than a decade has passed since the last published study of this kind at Walden Pond by Köster et. al. (2005). Results show a significant increase in indicators of eutrophic lake conditions since European settlement ca. 1630, and especially since the 20th century. However, relative Asterionella formosa and Synedra nana abundances had not changed significantly in the last decade since Köster et. al.’s 2005 study, and have in fact decreased somewhat, suggesting water treatment efforts by the Massachusetts Dept. of Environmental Protection (DEP) have had some success. Loss on ignition (LOI) of organic content shows a precipitous decline from the mid 19th century from 37% to 22%, representing intensive land clearance and development until the 1970’s when DEP management began. After that point, LOI rose, perhaps due to increased lake productivity, and has fluctuated around 25%. Relative Discostella stelligera abundance, while used in the WAl-3 piston core as a proxy for water depth, could not be used in the WAL-1 gravity core from this study as eutrophication has significantly impacted their abundance. Chrysophyte scale:diatom ratios corroborate an observed trend of increasing abundance in lakes globally since the 20th century, perhaps in response to rising global temperatures over the same period.

Would an underpass/tunnel on Keese Mills Road decrease the percentage of amphibian mortality due to road mortality?

Wed, 04/29/2015 - 18:09
Abstract: Road Mortality has had a huge impact on Amphibian populations worldwide. Several options are available to help maintain and preserve migrating populations across roadways. One method that is looked at during this study is underpass and fencing. In this study, I assessed the need for an underpass and if it could help reduce the amount of amphibian’s mortality by traffic and, if an underpass is necessary, properly predict a location. I also looked at if underpasses alone could reduce the mortality of amphibians. I constructed arrays and pitfall traps to simulate an underpass on Keese Mills Road at Paul Smiths and Santa Clara, Franklin County New York. I predicted that underpass would decrease the amount of amphibian being slayed. I also predicted that certain locations would have more usage then others. The results showed that there was no significant difference between the location of the sites and whether they would be used by the amphibians. The results also showed that there was no correlation between the species that were captured and the species that were killed.

White-tailed Deer Browse Preference: A Comparative Study of the Catskill and Adirondack Mountain Regions, New York State

Tue, 05/05/2015 - 14:23
Abstract: Abundant white-tailed deer (Odocoileus virginianus) in New York State, United States, affect forest regeneration and stand composition through feeding (browse) pressure. White-tailed deer browse preference of six different hardwood tree species in two mountain ranges, the Catskill and Adirondack Mountains, within New York State were compared in order to determine the extent of browse selection by deer. There were no statistically different browse selection by white-tailed deer within the Catskills or Adirondack study area or between each study site. Visual analysis of the study areas after concluding the study revealed that red maple (Acer rubrum) was the preferred browse species at each study site.
