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 USE VERSUS AVAILABILITY DIET STUDY OF AGE-0 FISHES IN NEAR SHORE WOODY STRUCTURE

Thu, 12/13/2018 - 14:09
Abstract: In 2014, the need for an ecological restoration program began at Paul Smiths College in attempt to restore or improve the shoreline along Lower St. Regis Lake. When restoring a shoreline, one must look at what organisms are using the area and how they are doing it. Invertebrates and fishes play a large role in distinguishing problems or changes in an environment, so we sampled both to add useful knowledge to the restoration program. Specifically, we looked to see if fishes were selecting for specific invertebrates (food), or if they did not have a preference. We used a backpack electrofishing unit to sample young of the year fishes near shore along three 60-meter segments, and a 100-foot bag seine to collect fishes offshore along the same segments. Invertebrates were sampled along the same segments and was done so by picking up all coarse woody debris and brushing the pieces off with our hands into a sieve bucket. Woody debris too large to pick up were scraped underwater using a standard kick net. Invertebrates were identified to order level, and fish stomach contents were also identified to the order so that we could conduct a comparison. After using a Chi Square test, we found that according to our p-value (0.2796) fishes were not selecting against any individual taxonomic group. Smallmouth bass were also the dominant present species along nearshore woody debris which could either suggest a higher recruitment than other species, a preference of use by the smallmouth bass, or human introduced capturing bias. Although we can’t indefinitely say fishes were selecting for Dipterans, data shows that dipterans made up just 4.5% of the total invertebrate composition on CWD but made up 9% of the fishes’ stomach contents suggesting fishes may be selecting for them.

Minnow Abundance in Heron Marsh: Spatial Variation, the Status of the Non-Native Fathead Minnow, and Hybridized Redbelly and Finescale Dace

Fri, 12/14/2018 - 09:27
Abstract: Due to their distinct influence on surrounding ecosystems and food web dynamics, minnow populations have been monitored in Heron Marsh, in the northern Adirondacks in New York, since fall of 2012. This study documented the presence of species known to predate on minnows, the hybridization between redbelly dace (Chrosomus eos) and finescale dace (Phoxinus neogaeus), and the presence of the recently documented fathead minnow (Pimephales prometas). To survey piscivores, two fyke nets were set around the marsh for one trap night. The fishes were then identified and measured. The collection of predators is part of a preliminary study to document the presence of predator fish species within Heron Marsh. Minnow data was collected via minnow traps set at long term study sites and one new site. The traps were set over night and collected the following day. The minnows were identified and measured to the nearest mm. When analyzing the data collected in the field, the data from previous years was compared to this years data. The findings indicate that hybrids of redbelly and finescale dace can be observed only at sites where both parent species exist. This 2018 study was the first one to document hybrid species though they have been observed in past years. The status of the fathead minnow is not significantly different from findings from 2017 however, their populations are noticeably smaller than previous years. Predator composition was primarily brown bullhead (Ameiurus nebulosus) and creek chub (Semtilus atromaculatus).

Assessing the Use of Backpack Electrofishing to Index Age-0 Fish Abundance in Woody Structure Adjacent to the Lakeshore

Fri, 12/14/2018 - 10:50
Abstract: The preservation and monitoring of age-0 fishes and their habitat is imperative to the overall health of a lake and its fishery. The effectiveness of backpack electrofishing at capturing age-0 fishes along shorelines with coarse woody structure was assessed by attempting to correlate electrofishing catch rates with known population sizes. A 60x2m controlled study area along the shoreline of Lower St. Regis lake was selected and blocked off through use of a net encompassing the perimeter. Known population sizes were stocked into the net and a three-pass electrofishing depletion was conducted within the study area. Results indicated that there was no significant correlation between the known population size and the population estimate generated through electrofishing (p = 0.172). The lack of correlation may have been due to failure of the block net encompassing the study area.

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 Taste of Tea

Thu, 11/30/2017 - 14:49
Abstract: Originating in Southeast China, tea is one of the most consumed beverages in the world, second only to water with coffee in third. Though tea has many names, they all come from the same plant, Camellia sinensis. There’s white, yellow, green, oolong, pu-erh, and black or red tea; each has its own variants and processing methods to distinguish them. Tea has spread throughout the world and each culture took these leaves and made it their own in different ways. The journey it has taken is an interesting one with a lot of controversy, conflict, and corruption once introduced to the British Empire.

Forest Structure and Composition in the Smitty Creek Watershed

Wed, 12/14/2016 - 09:56
Abstract: The 2016 Smitty Creek CFI (Continuous Forest Inventory) study addressed the issue of creating a reliable and repeatable inventory design to examine general forestry trends and their relationships with the watershed itself. Identifying these trends and their consequences is important when considering factors linked to climate change, such as carbon storage and allocation. The objective of this project were as follows: establish 10 new CFI plots, monitor and record for signs of disease and insects, tree mortality, and overstory wildlife habitat, accurately estimate forest carbon sequestration, record understory composition in a 1/50th acre area around each plot center, and suggest methods and reasons for application in Paul Smith’s College CFI capstone projects. The study was conducted within the Smitty Creek watershed in Paul Smiths, NY with the plots falling on a transect that runs north and south. At each plot, trees within the radius were assigned numbered aluminum tags, trees were measured at diameter at breast height, and other features, such as snags, were recorded. Upon completing the project, 10 CFI plots had been created and their locations were recorded, several diseases and forest health concerns were identified, as well as, tree mortality and wildlife habitat considerations, carbon sequestration for the watershed was modeled over the next century, and a CFI project was designed for the Paul Smith’s College land compartments. The Smitty Creek watershed CFI project is repeatable and has an accurate baseline of information for future studies, and the Paul Smith’s College land compartments CFI plot design is ready for implementation.

Management Plan of the Ring-Tailed lemurs (Lemur catta) at Beza Mahafaly Special Reserve in Madagascar

Tue, 05/03/2016 - 11:29
Abstract: The need to protect Ring-tailed lemurs is evident. Lemurs are the most threatened group of vertebrates in the world with the IUCN listing 94% of lemur species as threated. This high percentage is in part due to the fact that lemurs only occur naturally in Madagascar so changes to the island effects the whole infraorder (Lemuriformes). Helping to curb illegal activities will protect not just the habitat for Ring-Tailed lemurs but will help the entirety of Madagascar’s Wildlife that has evolved on an island that used to be covered by up to 90% forest. These illegal practices are often protected by armed guards which may require assistance from the Madagascar government for adequate protection of the islands forests

The Effects on Soil Caused by Garlic Mustard (Alliaria petiolata) in a Northern Hardwood Forest in the Northern Adirondack Mountains

Mon, 12/02/2013 - 10:54
Abstract: Plant invasions are thought to be among the worst causes of biological extinction and biodiversity loss in the modern world. With the United States spending upward of thirty four million dollars a year in attempts to control and repair the damages caused by invasive plants, not only are we feeling the biological effects, but we financially cannot afford to keep combating these invasive species (Barto and Cipollini, 2009). Garlic mustard (Alliaria petiolata) can invade multiple types of sites whether the soil is sandy or if a site has been disturbed. This invasive species will take over the understory and alter soil chemistry (Morris, McClain, Anderson and McConnaughay, 2012). This study aimed to look at how garlic mustard is affecting soils in the northern Adirondack Mountains in New York State. Although currently scattered and not very prevalent, there have already been changes to the soil chemistry. This study was conducted by setting up multiple plots within areas where garlic mustard was present and gathering soil to be used to test for nutrient values. It was found in this study that calcium, phosphorous, magnesium, potassium, sodium, aluminum and soil pH values changed due to the presence of garlic mustard.
