Compaction of Hiking Trails Located in the Northeastern Area of the Adirondack State Park, New York

Mon, 04/29/2013 - 12:19
Abstract: With continued increases in outdoor recreation in the United States, the physical impact of that use needs to be monitored for its effects. The purpose of this study was to explore whether a relationship exists between traffic numbers and soil strength of trails in the High Peaks Region of New York’s Adirondack state park. Soil strength was used as a measure of compaction because of its ability to indicate certain aspects of soil physical properties like bulk density, and hydrological condition (Mirreh & Ketcheson,1972), which are also soil physical properties that are effected by compaction (Hanna & Al-Kaisi,2009). These physical properties are important factors which influence a soils ability to carry out its biotic and abiotic processes (Kozlowski,1999). Initially the relationship between average soil strength of trails and traffic was insignificant. Upon further analyzing the data we found a significant relationship between on-trail and off-trail soil strength and used this relationship to create on-trail residual soil strengths. This was done to remove the influence that off-trail soil strength was having on the traffic vs. soil strength relationship. With the on/off-trail relationship influence removed, the relationship between on-trail residual soil strength and traffic was significantly improved. Literature discussed showed how the soil strengths collected could be used to infer possible effects on the sites tested. Relations between soil strength and bulk density, root elongation, root penetration, and trail recovery were all reviewed to provide insight on the quality of the soil at sample sites.

No Known Antidote: Quantification of a deadly toxin, tetrodotoxin, in red efts (Notopthalamus viridescens; Rafinesgue, 1820)

Mon, 04/29/2013 - 17:42
Abstract: Tetrodotoxin (TTX) in found in taxa worldwide including the eft life stage of the eastern newt (Notopthalamus virisdescens). Previous studies have shown that there is variability of TTX concentrations within efts and newts, and it is not known if the presence of TTX in these efts is common among populations. Our objective was to determine the distribution of TTX within the body N. viridescens efts. We hypothesized that the skin would have the highest concentrations of TTX as it is the area of the body that will likely come into contact with a predator. If certain regions of the skin come into contact with a predator more often than others, there may be significant differences in the dorsal, abdominal and pectoral regions of skin. Further, we hypothesized that the ova would have the second highest concentration of TTX as they are vital to reproduction yet vulnerable to predation. Through HPLC analysis we determined the concentrations of TTX within different tissues of N. viridescens efts including the: dorsal, pectoral, and abdominal skin; ovaries; testes; liver; pancreas; and alimentary canal. The concentrations of TTX between the different tissue types are not significantly different, nor were individuals significantly different in concentration of TTX from one another. Toxicity levels were high in comparison to other N. viridescens efts and more similar to the toxicity of highly toxic Taricha newts. The high toxicity of N. viridescens could be contributed to strong predation pressure by the slightly resistant garter snake (Thamnopsis sirtalis) and eastern hognose snake (Heterodon platirhinos).

The Conservation and Management of Wolverine (Gulo gulo) Populations in Northern Idaho to Help Prevent Human Caused Extirpation from the Contiguous United States

Thu, 05/02/2013 - 11:21
Abstract: Wolverines (Gulo gulo) were once a thriving species in the North Western United States, but large scale trapping and poison programs in the early 1900s lead to the species near extinction. Since then, populations in the United States have been struggling to maintain a strong presence in Idaho. Its current listing as threatened on the Endangered Species Act prohibits hunting and trapping, but more management is needed to sustain populations. Human development and recreation activities have caused wolverines to disperse from its nature range. Using habitat preservation techniques on current and historical wolverine habitat, increase availability and connectivity will improve dispersal. Close relationship with state officials will provide protection regarding land use, recreation, hunting, trapping and harassment. Public education will teach residents ways they can help prevent wolverine populations from further decline. Extensive research and population monitoring are needed due to the currently declining populations and the low fecundity of the species.

Evaluating the Recovery of Lakes from Acid Deposition in the Adirondack Park

Mon, 12/02/2013 - 22:49
Abstract: Acid rain has been an environmental problem since the 1980’s and has been a core issue in the Adirondack Park located in the northern part of New York State. Acid rain is created by acidic gases from anthropogenic uses that mix in the atmosphere with precipitation and forms acid deposition. Acid Rain lowers the pH of water which has detrimental effects on the biota living within lakes. There is a general consensus that the chemistry of lake water is recovering from acid deposition, however, there have not been sufficient studies on the state of recovery from acid rain in the Adirondack Park or much of the United States. This study will investigate if lake recovery is indeed happening in the Adirondack Park. This study analyzed the water chemistry of lakes using data collected from the Adirondack Lake Survey Corporation (ALSC) and New York State Department of Conservation (DEC). The object of this study is to find a trend in the water chemistry and combine it with DEC data to evaluate the present condition of lakes within the park. The results showed that there are not significant correlations of the data besides SO42- concentrations, which have been approving in the park in the last 20 years.

Alternative Management Methods for Acid Deposition in Lakes

Fri, 04/26/2013 - 18:09
Abstract: Acid deposition has been causing the acidification of lakes in the Northeast United States for decades. The result is lake ecosystems with abnormally low pH that stresses the organisms that live there. Management plans in place in the Adirondack Park have been working to remediate acidified lakes for the past few decades. Limestone (CaCO3) has been the generally accepted method for managing these lakes, in an attempt restore the lakes pre-impacted conditions. The purpose of this study was to evaluate the effectiveness of liming in reversing the effects of acidification, and to identify effective alternatives. Five alternatives were tested against limestone: Sodium carbonate (Na2CO3), Sodium bicarbonate (NaHCO3), Sodium acetate (CH3COONa), Magnesium carbonate (MgCO3), and Potassium carbonate (K2CO3). Double End-Point Titration tests were performed on all of the compounds, using both distilled water and lake water, to determine the relative alkalinity of each compound. Alkalinity is the measure of the ability of a solution to neutralize acid, also known as its "buffering capacity." Lake water was used in the titration tests in an attempt to mimic in-situ testing. The results of the titrations showed limestone proving to be the most effective in the lake water tests, with Magnesium carbonate and Potassium carbonate ranked closely behind. While limestone has proven to be an effective management method, its reliability is dependent upon the characteristics of the lake catchment, making it important to continue to look for alternative solutions.

Soil and Vegetation Characteristics of High Elevation Wetlands in the Adirondack Park

Mon, 12/03/2012 - 17:14
Abstract: Wetland ecosystems are finally being understood for their true importance. Wetlands in the past were misunderstood and thought to be disease carrying burdens on our way of life; however this mentality changed during the mid-19thcentury. These ecosystems are important for biodiversity and act as natural water purification systems. This study was undertaken to help understand, the high elevation wetland characteristics. Our goals were to analyze the soils and describe the vegetation in high elevation wetlands. The soil and vegetative surveys helped define the characteristics of these ecosystems and create a better understanding of them. The combination of vegetation species that are wetland indicators were found in each site, the soil pH, and nutrients show that each site had signs of being a wetland community.

The Effect of Temperature and pH on the Growth of Variable-leaf Milfoil (Myriophyllum heterophyllum)

Tue, 12/04/2012 - 18:03
Abstract: A fundamental part of invasion biology is the prediction of the potential spread of nonindigenous species (NIS). This is due to the negative ecological, economic and human-health effects that NIS may cause. Variable-leaf Milfoil (Myriophyllum heterophyllum), a highly invasive NIS to the Northeast, is native to southern U.S. states from Florida to New Mexico, and has since spread to North Dakota and southwestern Quebec without becoming invasive to those areas. Variable-leaf milfoil is invasive to the Adirondacks in northern New York State and is spreading at a rapid pace. This study questions whether temperature and pH have an effect on the growth of Variable-leaf milfoil. In this laboratory experiment, the growth of 80 Variable-leaf Milfoil fragments was examined in warm (33.1275°C) and cold (23.135°C) temperatures, combined with 10 pH treatments. Fragments showed increased growth in cold water when compared to the warm temperature treatment, and no relationship was shown between temperature and pH treatment in relation to growth.

A Land Management Plan for the Gottemoeller Family Farm

Thu, 12/06/2012 - 09:58
Abstract: Private landowners own property that is used for a variety of purposes. A management plan can help them realize their goals. This management plan focuses on two main goals. One is to maximize the sustainable out put of black walnut and other quality hardwoods. The other is creation of quail habitat to increase the carrying capacity of bobwhite quail on the farm. Using aerial photos and field visits, the property was divided into ten different management units. Some units have a forestry focus and others have a quail habitat focus or both. A Wildlife Habitat Appraisal Guide was used to evaluate the existing habitat and to identify which elements need to be improved. Peer reviewed research and agency technical expertise were used to identify which practices will improve the limiting elements for quail habitat. A Forest Plan developed by a professional forester with the Missouri Department of Conservation was incorporated into the farm Management Plan.

A MULTI-SCALE EVALUATION OF THE EFFECTS OF FOREST HARVESTING FOR WOODY BIOFUELS ON MAMMALIAN COMMUNITIES IN A NORTHERN HARDWOOD FOREST

Fri, 02/01/2013 - 16:19
Abstract: Forest harvesting and subsequent effects on forest structure have been shown to influence mammalian community assemblages and the abundance of individual species, however less attention has been paid to the implications of how harvested timber is used. This is particularly relevant in the Northern Forest, where a considerable portion of the forest harvesting is used to produce biofuels. Biofuels harvesting typically involves the process of whole-tree chipping which may lead to a dramatic reduction in the amount of woody material in the form of slash and coarse woody debris (CWD) left in harvested stands. The goal of our study was to assess the effects of biofuels harvesting on forest structure and subsequent effects on mammalian community structure and abundance. To address this goal, we focused on a ~35 Ha area of partially-harvested northern hardwood forest in the northern Adirondacks, New York. To sample mammals we used a combination of Sherman traps and track plates established at two scales across stands within this area. Our results showed that the response of small mammals to changes in forest structure is both species and scale specific. At the individual trap scale, CWD, slash, and understory cover were important drivers of the occurrence of individual species of small mammals. At the larger “grid” scale, small mammal relative abundance was driven by canopy cover and the density of woody stems. Our results indicate that the current harvesting practices used for biofuel production in the Adirondacks are unlikely to result in declines in abundance of common small mammal species. However, the retention of some slash post-harvest may be beneficial to some species, thus foresters may want to include slash retention when developing silvicultural prescriptions.

Managing for increased productivity and size of an American kestrel (Falco sparverius) population in northern New York

Mon, 05/07/2012 - 12:58
Abstract: American kestrel (Falco sparverius) populations have recently declined across most of the eastern states. As a result, managers and concerned citizens alike have installed nest boxes across large areas to increase productivity. Mr. Mark Manske has run one of these nest box programs in northern New York, across parts of St. Lawrence and Franklin counties, over the past ten years. Through the combination of his research and other long term management plans, the ideal future plan was developed. The focus of the new plan is to boost efficiency of resources, ease of expansion and sustain a steady or increasing population of kestrels. GIS software was used to analyze each nest boxes’ characteristics in order to develop a model that may predict areas of possible high productivity. Surveys and public outreach are emphasized to create a broader supporting base and possibly acquire future partners for land use, volunteers and advertising. The continued monitoring of the northern New York kestrel population will ensure the presence of this vital species for generations to come.
