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.

Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.

Interpreter's Guide to the Finger Lakes Trail

Wed, 04/29/2015 - 21:44
Abstract: Guidebooks help hikers to navigate trail systems and gain a better understanding of their surroundings. Many types of guides exist for popular long distance hiking trails such as the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail. The Finger Lakes Trail (FLT) runs 558 miles across the base of New York State, yet has very little associated literature. I hiked a 52 mile section of the Finger Lakes Trail from Ellicottville to Portageville in western New York. Using observations from the trail and related literature, I wrote an interpretive guide for this section. My FLT interpretive guide covers topics related to planning and packing for a multiday backpacking trip, natural history of western New York forests, the story of the development of the FLT system, and backpacking ethics. This work will help satisfy the human need to acquire knowledge and potentially enrich the experience of FLT hikers.

Limnological Report of Marvin (Potters) Pond

Thu, 04/30/2015 - 09:51
Abstract: Long term data of limnological conditions is crucial to understand lentic freshwater ecosystems. Marvin (Potters) pond is a 2.04 hectare kettle pond located in Franklin County, New York in the Northern Adirondack Park. There have been numerous short studies of the pond over the past 30 years but the pond has never been intently monitored to date. The pond is assumed to be meromictic by the NYSDEC. The objectives of this study are to 1) calculate the morphometry of the pond and its watershed; 2) the determination of the trophic status of the pond; 3) to document the chemical composition of the pond, particularly as it relates to acidity and acid neutralizing capacity; 4) to document the annual dynamics of temperature and dissolved oxygen. Evidence from profile data on dissolved oxygen and total iron suggests that the pond is monomictic with the capability to be meromictic under certain climatic conditions. The mixing period of the pond occurred in the month of November. The morphometry of Marvin pond was found to have a conical cross sectional area and large depth for the surface area of the pond. The trophic state of Marvin pond was found to be eutrophic for chlorophyll-a and total phosphorus concentrations but mesotrophic for the secchi disk reading. The acidity of the pond was found to be high with a low buffering capacity.
