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.

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.

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.

Building Families Stronger

Tue, 05/05/2015 - 14:05
Abstract: The purpose of this study is to design a program that can be implemented in local camps to accommodate the needs of individuals in a family group affected by mental illness. The study will explain the importance of educating individuals about mental illness and integrating supportive behaviors. This program is designed to help families cope with the effects mental illness can have on the entire family dynamic. Families are often the strongest support system for dealing with mental illness and educating families is essential for success of the mentally ill. Team building games are used to enhance social behaviors and encourage group bonding, this program uses a recreational therapeutic approach to addressing issues in the lives of those affected by mental illness. To figure out how many people will be most likely be using the therapy program, a survey was created using a series of questions that went with the topic for respondents to answer. In fact the survey established that the majority of people agree on recreational approach to therapy as a means of coping with their illness in real life tasks. Other questions asked was what their favorite activities where, such as paddle sports and hiking. Another question was what disability was so as to get an idea what accommodations would be need and services for patients involved with the program.

Downtown Saranac Lake Urban Forest Management Plan

Thu, 05/07/2015 - 16:47
Abstract: Trees and green spaces are important resources to any community. They are public spaces which provide havens of relaxation, play, and mental and physical stimulation. Trees and green spaces have been proven to have a positive impact on the mental and physical wellbeing of area residents. However, the care of these trees and green spaces is often overlooked or not planned for, leading to human/nature conflicts at a fine scale (local level). This is where arborists enter; arborists are individuals trained in the art of caring for trees, and are often involved in every stage of a tree’s life cycle, from planting to removal. But arborists are also teachers, acting as the intermediary between urban trees and the public and providing education to the people. The village of Saranac Lake, New York, is no different. The results of the data collected on Saranac Lake’s downtown street trees and parks were analyzed and compiled into a comprehensive urban tree management plan. A total of 236 trees and shrubs were inventoried and assessed for their health, overall condition, and pruning needs. Also included in the urban tree management plan are observations on the current state of the urban forest, recommendations for the mitigation and correction of any observable problems, and prevention and treatment courses of action for any future insect pests.

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.
