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.

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.

Tetrodotoxin- toxicity of red efts (Notophthalmus viridescens) based on predatory selection

Thu, 04/30/2015 - 09:33
Abstract: Predators and prey have been coevolving for millions of years; those that have more aggressive relationships undergo more extreme selection as they become paired in an evolutionary arms race. This selection must affect both organisms to truly be an arms race; a relationship that accurately fits these criteria is that of the Eastern Red-Spotted Newt (red-efts) (Notophthalmus viridescens) and the Eastern Hognose Snake (Heterodon platirhinos). Samples of tetrodotoxin (TTX) extracted from red-efts were used to analyze a potential relationship between the efts and resistant predatory species. The values acquired upon analysis of samples were recorded from a population of organisms in an area vacant of the hognose and can be compared to areas where both species reside. Samples came from eighteen red-efts in a wetland located in the southeastern portion of the Adirondack Park where there are no known populations of the hognose snake. These samples were processed using various ELSIA grade chemicals, a procedure that concluded with ELSIA assays applicable for comparison to a set standard. By performing this study we hope to attain data pertaining to tetrodotoxin levels in red-efts that reflect an environment which does not contain hognose snakes, presented in the form of low levels of the specified toxin.

Acidic Deposition in Adirondack Lakes: Episodic Acidification and Equilibrium

Tue, 05/05/2015 - 10:06
Abstract: Acid deposition has been a historic problem in the Adirondacks. Though after original mitigation attempts were deemed successful, funding for many acid deposition-monitoring programs in the area has been cut or eliminated, and much of the data that has been collected is now old and outdated. Newer data on this issue needed to be collected to determine if there truly has been recovery of Adirondack lakes. Through this observational experiment the pH levels of 18 different lakes scattered around the Adirondacks during winter were examined. The pH levels of the snow around the lakes were examined to determine the levels of acid shock. This data was compared to the historic data available and created a preliminary finding. This comparison helped determine that Adirondack water bodies could possibly be coming to a form of equilibrium as the pH levels are possibly returning to a resemblance of pre-disturbance conditions, which suggests recent legislation may have had measurable successes in the goal of reducing the acidification of Adirondack freshwater ecosystems.

Reintroduction Feasibility of the Adirondack Wolf

Tue, 05/05/2015 - 11:14
Abstract: Mammalian carnivores are increasingly the focus of reintroduction attempts in areas from which they have been extirpated by historic persecution. The gray wolf (Canis Lupus) has been one of the most successful examples of large carnivore reintroduction around the world. The purpose of the study is to determine whether or not it is possible to successfully reintroduce the gray wolf into the Adirondack Park environment. Static and dynamic spatial geographical models were used to evaluate whether a proposed wolf reintroduction to the Adirondack Park is feasible. Ecological, economic, and sociopolitical aspects are limiting factors that are analyzed to determine if the reintroduction is structurally possible for the park.

PHOTOVOLTAIC POWER IN FLORIDA

Fri, 05/08/2015 - 16:16
Abstract: For the future, it is now essential to diversify energy sources. The sun is not an alternative energy source; continued use of fossil fuels should be considered the alternative source. Despite the amount of sun received by the Florida peninsula, solar energy is not currently used to its fullest advantage. Florida can invest in Photovoltaic systems and use the sun for an advantage. Solar energy offers power without the need to burn fossil fuels. In its basic form, it needs no distribution grid because it comes down from the sun. Literature indicates Florida could be in the top three states, within the United States, to produce solar energy.

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.

A Meta-Analysis of the Impacts of Professional Bass Fishing Tournaments

Mon, 04/29/2013 - 19:28
Abstract: Professional black bass (Micropterous spp.) fishing tournaments have significant economic benefits associated with them; however concerns about various negative ecological effects are being raised. Fish mortality has the potential to be critically high following release of the fish, whether it be from stress, hooking injuries, heat exposure, disease, or a lack of sufficient oxygen. Mortality can occur prior to release, or it can occur several days to even weeks after release. The vast majority of organized tournaments release all of the fish in one specific location once the weigh-in process has been completed. The lack of dispersal among bass once they are released back into the water is another key issue. Utilizing 17 different studies on mortality and 8 studies on dispersal, this meta-analysis study looks at how tournaments can affect the bass population in lakes and rivers across the country. It also examines the variables that affect mortality and dispersal such as season, water temperature, location, and species of bass. The potential ways for the survival rate to be improved is also discussed. The results of the meta-analysis showed that water temperature had a significant impact on mortality, as did the time of year the tournaments were held. Mortality was highest from a period of 1-10 days following the tournaments, but was still occurring up to one month after. Dispersal was highest for Largemouth Bass, and for Spring-held tournaments. The study concludes that there are several ways to potentially lower the tournament associated mortality rate for black bass.

Management Plan for Nuisance Populations of North American Beavers Castor canadensis in New York State

Mon, 04/30/2012 - 20:27
Abstract: The North American beavers Castor canadensis are a keystone species that were once nearly extirpated in New York State in the late 18th century. This was due to the destruction of their habitat and over trapping. Beavers have been successfully relocated back into New York State. Beavers provide a major role in manufacturing intricate food webs and, are beneficial to increasing the diversity of a landscape. However in certain areas of the state the beaver populations come into conflict with human communities. The conflict results from damage to public and private lands. Beavers damage crops, human structures and contaminate water supplies by flooding. The damage created by beavers creates a safety as well as an economic issue. This management plan will give various methods of reducing the beaver population in areas where they cause severe amounts of damage and hefty costs associated with repairing the damage; without completely extirpating the beavers from the landscape.
