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?

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.

Impacts of Maple Syrup Production Programming at the Paul Smith’s College Visitor Interpretive Center
Tue, 04/29/2014 - 12:37
Abstract: Education and interpretation provides strategies and techniques to successfully communicate natural resource and environmental concerns. This research addresses the effectiveness of a community education project at the Paul Smith’s College (PSC) Visitor Interpretive Center (VIC) in the Adirondacks of New York State. Educational programs regarding maple syrup production were designed and evaluated to determine their impact on the local community. The objectives were to offer skills education, raise awareness on a local resource, foster a connection to the land, and offer involvement in the VIC’s community maple project. The goal of maple education at the VIC is to educate the community in an attempt to encourage the growth of an underutilized sustainable local resource that community members can become involved in without degradation of Adirondack forests. Determinations were made using a survey questionnaire provided before and after the programs were performed. Based on the data collected the determination made is that the majority of participants that attended ultimately were interested in becoming involved in maple sugaring using to VIC as a gateway for maple sugaring, primarily as a hobby and outdoor activity. This research has aided in the determination that effective programming at the VIC results in encouraging the community to be involved in maple syrup production. With this determination the VIC will continue to perform the designed educational programs as a service to the community.
