Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

A Comparison Study of Adirondack Region Clearcutting Implementation to that of Paul Smith’s College VIC FERDA Plots

Mon, 05/02/2016 - 10:44
Abstract: The students of Paul Smith’s College have a unique opportunity to explore the parameters of silviculture and forestry practices. Gaining the base knowledge of silvicultural systems while also, properly implementing timber harvesting methods in order to achieve the specific goals and objectives of these systems is tremendously useful for implementation in future years. This study investigated the silvicultural prescriptions of the Forest Ecosystem Research and Demonstration Area (FERDA) plots on Paul Smith’s College lands, in Paul Smiths, New York. Comparing the inventory of the two clearcut sites upon these lands to that of other harvests within the Adirondack Park can supply further knowledge on what can be expected after a specific silvicultural system. Clearcutting has the greatest effect on forest succession by removing the forest cover and allowing light to reach what was once a shaded forest floor. Comparing experimental five acre clearcuts to that of larger commercial clearcuts in the same region can further our understanding of regeneration composition after such timber harvesting operations occur. The variance between the age of the FERDA plot harvests and the age of the harvests completed on Landvest timberlands resulted in varying data. However, if four to eight more years was given for pseudo FERDA plots to mature, it is believed that these harvests would be similar in composition and structure.

Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

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.

The Effects of Varying Wavelengths of Light on Diatom Movement

Wed, 05/06/2015 - 16:18
Abstract: Diatoms were studied in order to determine in which wavelength of light they would be most active. It was surmised this knowledge would allow easier testing of future diatom movement hypotheses. This knowledge could, in turn, allow control over diatom movement in order to prevent or circumvent hazardous diatom blooms. Specimens were studied using a Parco scientific microscope in a dark room. They were studied both with and without cover slips to ensure the cover slips did not hinder movement. Sheets of high quality color transparency paper were laid over the microscope light, producing a single, strong color. In the end, the diatoms didn’t move at all, no matter the circumstances. The diatoms could have had no reason for movement or have been restricted by the small amount of water on the microscope slide due to the vast difference between the slide and the diatoms’ natural environment.

Examination of Potentially Ectoparasite-driven Behavior in Burrowing Owls: Tests of Alternative Hypotheses

Thu, 05/07/2015 - 19:06
Abstract: Burrowing Owls (Athene cunicularia) and their nests harbor at least 39 species of arthropods from 21 different families. Among the ectoparasites on Burrowing Owls are fleas, which are primarily Pulex irritans (Family Pulicidae), the human flea. Fleas can number in the hundreds on individual Burrowing Owls. Thus, we hypothesized that flea infestation has shaped Burrowing Owl behavior to avoid the costs of ectoparasitism. As part of experiments using infrared trail cameras deployed at Burrowing Owl nests in southern Idaho ¬¬during 2012-2013, we noticed apparent sunning behavior in both adult and nestling Burrowing Owls. Camera images captured owls lying on the ground with wings outstretched and flat. We only observed this behavior during daylight hours, although cameras were active for 24 h/day. Sunbathing in birds is often associated with ectoparasite reduction, although sunning has not previously been examined in relation to flea infestation. During 2014 we conducted an experiment that included fumigating some nests with a flea removing insecticide and examined the prediction that sunbathing would occur more frequently in control nests where ectoparasites remained. As sunning was not during the coolest parts of the day, it did not appear to function for warming. Also, we ultimately found no difference in the frequency of sunning in fumigated and control nests, and there was no relationship between sunning and abundance of fleas on owls. Thus, the evidence is not consistent with the ectoparasite hypothesis, as owls sunned irrespective of flea load. We also evaluated the alternative hypotheses that sunning was related to thermoregulation, anting, drying or feather degrading bacteria. The first three we were able to reject, and the last will need future research.

Best Management Practices for Cultivating Cold-Weather Shiitake Strains in the Adirondack North Country

Fri, 05/01/2015 - 09:55
Abstract: Shiitake (Lentinula edodes) cultivation has become an important tool for private woodlot owners to diversify their income and manage their woodlots more efficiently and sustainably. Through the art and science of mushroom cultivation three strains of shiitake have been created for varying climates: Wide Range (WR), Warm Weather (WW), and Cold Weather (CW). This study proposes that CW strains would be most ideal for the Adirondack North Country because growing conditions now and in the future are nearly optimal. CW strains have a shorter fruiting period (spring and fall) than the WR and WW; therefore, the mushroom production potential of the CW is underutilized. In order to get maximum production of their logs, most growers use a method called shocking to induce fruiting with WR and WW; however, research has shown that shocking does not trigger fruiting in the CW strains; rather, CW strains respond to temperature fluctuations. Taking this into account, we’ve introduced a hybrid approach of growing CW shiitake, which combines outdoor and indoor cultivation techniques to best imitate that temperature fluctuation. Growing CW shiitake using a hybrid approach can be the best choice for small-scale growers who wish to extend their growing season into the winter months, thus opening new market opportunities. By conducting interviews with shiitake growers in similar climates and compiling and analyzing literature from other professionals, we have gathered data on log harvesting, laying yard conditions, moisture management, and lighting conditions and developed a best management practices guide for small-scale shiitake grower/woodlot owners in a northern Adirondack climate. Ultimately, growers could diversify their sources of income, provide incentive to manage their woodlots and most importantly learn how to effectively utilize CW strains through the winter months.

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.

Vermont Maple Forest Products LLC. Forest Management and Business Plan

Wed, 12/02/2015 - 17:52
Abstract: Maple syrup production is an extremely important aspect of the American economy in the northeast, generating around 132 million dollars in revenue annually across its U.S production range (United States Department of Agriculture, 2014). At the current rate of production U.S producers are presently only tapping 0.4% of the maples which may be available (Farrell & Chabot, 2012). Vermont has the greatest number of its trees tapped, with 2.94% of available trees currently in production. The low percentage of tappable maple trees in production has been seen as a short coming in the industry. However, this does create the possibility for entry into the industry. Vermont Maple Forest Products LLC is in current maple production and desires to produce on an industrial scale. Simon Boulet and Claude Deschenes (2005) found that the highest degrees of profit are generated when a producer is considered a medium(5,000-19,000 taps)-large (>19,000 taps) supplier. At this point costs per tap are reduced and sap yeilds increase. Vermont Maple Forest Products currently has the land available for potentially over 28,000 taps. To achieve this goal a business plan and forest management plan was developed and will be implemented across the tract with the goal of maple syrup production.
