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.

ECTOMYCORRHIZA’S INFLUENCE ON SEEDLING GROWTH

Tue, 12/04/2018 - 14:16
Abstract: Mycorrhizae play an important role in forest ecosystems through their symbiotic relationship with trees and root systems. Of the mycorrhizae, ectomycorrhiza (EM), specifically targets softwood species and some hardwoods. In this experiment, the results of a powdered EM inoculum and red oak (Quercus rubra L.), pitch pine (Pinus rigida Mill.), and red spruce (Picea rubens Sarg.) were evaluated during one growing season. The study compared a control of no EM and treatment with EM in seed grown trees in containers. Difference between heights of the treatment and control were recorded to see if the inoculum impacted seedling growth of the host species. Throughout this capstone the hypothesis states: An ectomycorrhizae (EM) powdered inoculum would influence pitch pine, red spruce, and red oak seedlings height and biomass for the duration of one growing season (April-Late August). Red oak control exceeded treatment in biomass but not height, and pitch pine and red spruce treatment exceeded control in height and biomass.

Coarse Woody Debris Volume Following Conventional and Whole-Tree Harvesting

Tue, 12/04/2018 - 16:50
Abstract: Coarse woody debris (CWD) affects important ecological patterns and processes in the forest, including nutrient cycling, carbon stocks, wildlife habitat, regeneration dynamics, and hydrology. Timber harvesting practices have been shown to affect the abundance and distribution of CWD in forest stands. This study separates timber harvesting practices into two categories: conventional harvesting (CH), where only the main stem of trees and possibly some large branches are harvested, leaving branches, twigs, leaves, buds, and other plant parts to decompose on the forest floor, and whole-tree harvesting (WTH), which removes the entire aboveground portion of trees. I measured post-harvest CWD volume within recent patch clear cuts in Vermont, comparing results between CH and WTH. Conventional harvesting sites contained significantly more (p = 0.04) CWD volume (954ft^3/ac) than WTH sites (422 ft^3/ac). In other words, CH resulted in a post-harvest CWD volume 126% greater than the volume resulting from WTH. The most important difference was a wide discrepancy between treatments in decay class 2, which contained 66% of the total CWD volume. The increased reduction of CWD through WTH, especially when carried out over multiple rotations, may have negative effects on future site productivity, as well as richness and abundance of wildlife. The choice to employ CH or WTH may also affect the carbon balance, regeneration dynamics, and hydrology of forest stands.

Antifungal activity of propolis, neem oil, and cedarwood oil against the white-rot fungus Trametes versicolor on American beech

Fri, 12/07/2018 - 16:27
Abstract: Fungi are often considered the most destructive organisms to attack wood that has gone through the milling process, so developing compounds to resist decay are extremely important. Copper chromated arsenic (CCA) was an industry standard until 2003 when its use was restricted due to environmental concerns. Thus, research into environmentally friendly compounds has become more common. This study investigated which compound, propolis extract, neem oil, or cedarwood oil, would best preserve beech wood exposed to Trametes versicolor. Extracts for each of the compounds were prepared using denatured ethanol, and infused into wood blocks using a vacuum pump. Blocks were made of American beech (Fagus grandifolia Ehrh.) and were 10mm x 20mm x 5mm in size. The blocks were subjected to a common white-rot fungal strain, Trametes (= Coriolus) versicolor (L.) Lloyd (1920), for six weeks. Overall, propolis and cedarwood oil treated blocks lost significantly less mass than both neem and control blocks, suggesting they have potential for use as natural wood preservatives, and could be used as cobiocides.

PROPOSED DAY-USE SITE AT THE ADIRONDACK LAND TRUST GLENVIEW PRESERVE

Fri, 12/14/2018 - 15:43
Abstract: Glenview Preserve is a lowland mix deciduous forest that boarders the Bloomingdale Bog. The property would be a quintessential location for public engagement through a day-use site, which in turn would ensure future use and elevation of the Adirondack Land Trust and their mission objectives. Through the determined design goals and the predetermined ALT goals for the property a comprehensive blueprint has been presented. The proposed day-use site is predicted to increase the three essential services that communities in the Adirondacks thrive off of. Their economic value, health and environmental benefits, and their social importance streamlines with the ALT’s management practices and goals to provide a beneficial educational and recreational space for the community.

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.

Creating a Reliable Surveying Network: Does Adding New Survey Control Points to Paul Smith’s College Campus Enhance its Current Network?

Tue, 12/05/2017 - 18:48
Abstract: The goal of the project was to improve the current geometry of the Paul Smith’s College surveying network. Four new survey control points were added to the current network allowing for new connectivity to old control points. Previously, there was a Westside network and an Eastside network that were not connected and by connecting these two networks, it has expanded the current network further into the campus. Two different methods were used to help identify the new network. A traditional survey method, a closed traverse, was used to connect the old control points to the new control points by utilizing a Nikon DTM-352 series total station. A X90 OPUS GPS unit was used to connect the new control points into a geodetic network. After the data was collected a least squares adjustment was done to the closed traverse to correct for error within the traverse. The GPS data was processed by Topcon Tools utilizing a Continuously Operating Reference System (CORS) to obtain a better level of accuracy for the network it produced. The two different techniques used produced different results in the overall survey networks and supplied different coordinates than what has been previously used by students at the college. These results gained from the project are not of a consistent level of precision and are not recommended for use without conducting more closed traverses to increase precision within the network.

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.

Predicting the amount of usable lumber contained in American beech (Fagus grandifolia) logs infected with beech bark disease based on exterior defects.

Wed, 12/02/2015 - 10:09
Abstract: Beech Bark disease has had many effects on the hardwood forests of the northeastern United States. Many studies have been done in regards to the changes caused by the disease affecting the ecology, species composition of the forest, abundance of American beech (Fagus grandifolia), and physiology of individual trees. However, American beech is a dense, strong species that machines and bends well, and has uses in the form of flooring, handles, and some furniture. This study examines how the severity of beech bark disease affects the amount of usable lumber that can be recovered from American beech sawlogs. To do this, American beech sawlogs with varying degrees of beech bark disease infection were harvested, bucked and scaled. These logs were rated according to their degree of beech bark disease infection based on exterior defects such as raised or sunken cankers, fissures and evidence of scale insect. These logs were then sawn into lumber form and rescaled to find a percentage of usable lumber that resulted from the gross scale taken prior to sawing. There was not a definitive relationship between degree of infection, and lumber yield. This study will be useful to the stakeholders of the lumber industry to aid in predicting whether or not a log infected with beech bark disease can be economically used for lumber.
