The Barrio Project

Humanities Alumni Association Outstanding Student AwardThis investigation is based on interviews and experience with women from a Columbus community of 2,000 low income Spanish-speaking immigrants, asking them about their daily lives and how they found information about resources in the area. The goal was to gather information that could be useful for outreach organizations to spread awareness about health care for the barrio. This paper proposes that if organizations create interpersonal relationships with the barrio, then they can spread their information, and therefore improve the overall health of the larger community.Pressey Grant College of Arts and Sciences Grant Honors and Scholars Gran

Composition and ecophysiological proficiency of tidal freshwater forested wetlands: Investigating basin, landscape, and microtopographic scales

A hierarchical approach to forest community assessment was conducted by first focusing on landscape associations to edaphic factors among major tidal freshwater forested wetland basins in the Southeast. Four general tree communities exist along coastal rivers in the southeastern United States, based on the most prominent species in each: Water Tupelo, Swamp Tupelo, Dwarf Palmetto, and Cabbage Palm. Microhabitat usage and preference by trees were then examined, both across all species and within species, as related to such factors as coast, presence on rivers with dams, tree community assemblage, relative distance from the river, specific river basin, and microsite availability. There are significant differences in the relative use of microsites in relation to most factors, both on a species-specific basis, and across all species. Twenty-one species use hummocks more than hollows, while only three species use hollows more. Finally, the processes driving these preferences in individual trees through dedicated water use studies on baldcypress trees in various settings (e.g., flooded vs. non, on hummocks vs. in hollows, in slightly saline vs. freshwater environments) were examined. While mature baldcypress trees increase rates of sap flow during flooded conditions, their rates of sap flow are not influenced by microsite position, and they have lower total sap flow in higher salinity environments. Sap flow rates are maximized at different radial depths into sapwood that differ with salinity. This study increases our understanding of tidal freshwater forested wetlands at the regional level, thereby providing a better base of knowledge from which future management goals can draw. A broad understanding of community composition, their associations with soil and hydrology, and usage of microtopography may help direct future restoration efforts. Learning the physiology associated with water transport in trees under differing environmental conditions will allow us to understand the specific physiological requirements of trees at different microtopographic and landscape positions
