What Are the Differences in Trichome Density and Morphology Between Arabidopsis Lyrata Subsp. Lyrata Populations When Grown in A Northern Common Garden, Outside of Their Geographic Distribution?

Tue, 04/30/2019 - 15:23
Abstract: Trichomes are diverse among plants. There is evidence suggesting that environmental factors may influence these structures and their densities. Other evidence shows that weather may influence genetics and gene expression. Arabidopsis lyrata subsp. lyrata is a wild flower that is native to North America and Europe and has been extensively studied. Literature regarding Arabidopsis states that within the family and genus, there is evidence suggesting that trichomes can be either non-branched, twice branched or thrice branched. This study’s purpose was to analyze how trichome density, and morphology in Arabidopsis lyrata subsp. lyrata differs between populations when grown outside of the natural distribution limit. Four populations of Arabidopsis lyrata subsp. lyrata were studied based on latitude. After analyzing the outcomes, unexpectedly there are no major differences between the north and south populations; however, there are differences between the four populations. Based on the data gathered, it was determined that the population, North2 (07G) must be genetically different from the other three populations. The four populations were grown together in a common garden; thus, all variables were the same. The environment did not influence trichome density or morphology within the North2 population, therefore the structures were genetically pre-determined.

Alumni Campground and the relationship with seasonal guests and wildlife

Tue, 12/17/2019 - 00:45
Abstract: For our capstone, we plan to focus on the wildlife and human interaction dynamics within Paul Smith’s College Alumni Campground. The objective of Owen’s section for capstone is too develop a ‘bear-awareness’ program for the Alumni Campground. Katie is looking into establishing a wildlife management plan of the campground correlating with the evidence of determining where there are patterns of travel within the campground of the local wildlife.

Planning and Future Management of the Adirondack Land Trust Glenview Preserve

Sat, 05/11/2019 - 08:51
Abstract: The Adirondack Land Trust purchased a 238 acre parcel of land, Glenview Preserve, from the Trevor family in 2016. The Glenview Preserve is located along New York State Route 86 in Harrietstown. The Glenview Preserve already consists of a heavily visited scenic vista of Whiteface Mountain, the McKenzie Range, and other Adirondack High Peaks. The property borders the Bloomingdale Bog, the third largest boreal peatland in New York State. The Glenview Preserve can be a perfect spot to incorporate a trail system to allow visitors the opportunity for non-consumptive recreational activities. When creating a trail system for recreation it is important to examine the impacts on local flora and fauna. A clearly designated trail system is the number one way to mitigate impacts on soil, vegetation, wildlife, and water created by visitors. Within the preserve interpretive signs will be implemented to educate and inform visitors on proper usage of the trail system. The unique thing with the area is the gradual grade of only 50 feet so the breathtaking views are virtually accessible to everyone who visits. Recreational activities allow people to get outside and enjoy nature and hopefully build personal environmental stewardship. The trail system will not only allow recreational opportunities for visitors but establish a sense of an outdoor community.

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.

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.

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.

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.

Environmental Factors Influencing the Establishment of Moss Species in the Elevator Shaft on Whiteface Mountain: A Descriptive Study

Wed, 12/02/2015 - 15:19
Abstract: The moss species growing in the elevator shaft on Whiteface Mountain have not yet been identified and little is known on the environmental conditions in which they exist. Light, moisture, substrate pH, and temperature play vital roles in the establishment and reproduction of moss. In the summer of 2015 eight moss species, present only in their gametophyte generation, were identified in the shaft. Four of these species are known to exist on the mountain outside of the elevator shaft. Temperature and relative humidity were measured to represent the conditions of the shaft, whereas available light, moisture, and substrate pH were measured with each colony. Temperature and humidity became more stable further into the shaft, similar to that of a cave environment. In addition, temperature peaked during the hours the elevator was in operation. Light, moisture, and substrate pH of each species were not strongly correlated with colony area. Most colonies were found to be growing on a type of sediment, rather than directly on the granite wall of the shaft. The pH of these substrates ranged between 6.68 and 8.99. The influx of tourists on Whiteface between May and October may play a vital role in the establishment of these species. The elevator may provide air circulation within the shaft and the electric lights omit the radiation necessary for the mosses survival. There is a 6 month period with possibly no light source or circulation of air. Further research should document these changes in environmental conditions during this period.

White Pine Blister Rust at Paul Smith’s VIC: Concerns and Recommendations

Tue, 05/05/2015 - 18:34
Abstract: Abstract- Blister rust was reported on the Paul Smith’s VIC property. White pine blister rust is a complex disease pathosystem in which Cronartium ribicola – a rust fungus - infects both eastern white pine (Pinus strobus) and species in the Ribes genus. P. strobus is a disturbance species in the Adirondacks. Ribes spp. are early seral stage plants and readily exploit small gaps in the forest. Both are found on the VIC property. C. ribicola limits white pine regeneration, but isn’t currently considered a serious forest pathogen in the Northeast because its spread is limited by environmental, topographic, climatic, and temporal conditions. Despite these limits, blister rust has moved around the globe and has successfully spread across a wide range in the U.S. Because blister rust exists in a dynamic and interconnected world, there exists the potential for it to increase in virulence and incidence. Historically, management of blister rust has involved removing ribes from the landscape in favor of white pine- a scheme that is too costly and yields little long term benefit for landowners. A gap in the knowledge exists for smaller landowners dealing with blister rust. With this considered, based on a wide body of literature, management plans were designed to fit the VIC’s needs now and in the future.

An Examination of the Paul Smith’s Visitor Interpretative Center Trail Conditions and Suggested Sustainable Maintenance Practices

Tue, 05/05/2015 - 10:59
Abstract: The Adirondack Park is a 6.4 million acre state park in Upstate New York. With over 2,000 miles of hike able trails, this region is a popular tourist attraction in the Northeast. Thousands of people visit the Adirondack region to hike each year, which means that the trails within the park are subject to high intensity use. Natural resource management professionals such as the New York State Department of Environmental Conservation (DEC) and the Adirondack Park Agency (APA) are concerned with the quality of trails winding through the region, and also promote awareness of the fragile alpine ecosystems resting atop the 5,000+ ft. tall mountains- which are constantly being degraded by human foot traffic. However, there are smaller and less maintained trails that run through our own backyard here at Paul Smith’s College, at the Visitors Interpretative Center (V.I.C.), with equally as fragile and important ecosystems. These range from bogs to eskers- the home of the rare and interesting Pitcher Plant (Sarracenia purpurea), to wetlands and riverine systems containing native heritage Brook Trout (Salvelinus fontinalis), populations such as the Windfall strain. Currently, there is no formal data documenting the condition of trails within the VIC property, therefore one may never know the true condition of the entire trail system. The Paul Smith’s V.I.C. can greatly benefit from applying recommended management techniques in the future using up to date information gathered in the spring of 2015. This report will provide new data, which will help management professionals examine the feasibility of applying accepted current and future sustainable trail management practices to the trails belonging to Paul Smith’s College.
