Determining the Effects of Fire on Ridge Shape Complexity In the Central Everglades
Title
Determining the Effects of Fire on Ridge Shape Complexity In the Central Everglades.

Abstract/Description
Self-organized spatial patterning of microtopographic features is a trademark characteristic of the Everglades landscape. Anthropogenic modifications to Everglades’ hydrology have reduced and degraded pattern, where ridges occur at higher elevations and spread into open water sloughs under dryer conditions. Wildfire is an important ecological force in the central Everglades and may maintain ridge-slough patterning through reducing ridge size and complexity, and thus preserve habitat...
Show moreSelf-organized spatial patterning of microtopographic features is a trademark characteristic of the Everglades landscape. Anthropogenic modifications to Everglades’ hydrology have reduced and degraded pattern, where ridges occur at higher elevations and spread into open water sloughs under dryer conditions. Wildfire is an important ecological force in the central Everglades and may maintain ridge-slough patterning through reducing ridge size and complexity, and thus preserve habitat heterogeneity. To investigate fire as a patterning mechanism in the central Everglades I examined the shape complexity and area distribution of ridges along a chronosequence of time since fire. Shape complexity did not change following fire, but small and large ridges became more prominent and eventually spread as time since fire increased, suggesting fire may maintain ridge area distribution. Documentation of fires’ effect on ridge size will inform ecosystem and conceptual models detailing the complex interactions that maintain the Everglades ridge-slough patterning.

Landscaping Practices, Environmental Ethics, and Sustainability in South Florida
Title
Landscaping Practices, Environmental Ethics, and Sustainability in South Florida.
Creator
Maki, Iiro, Harris, Michael S., Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of Anthropology
Abstract/Description
The research conducted for this thesis explores the link between environmental ethics and household landscaping practices. The central issue of any concept of sustainability is the incommensurability of various elements that define approaches, which is why it is treated here as a politicoethical process of subjective valuation. The ethics of sustainability were delineated according to major currents in environmental ethics, as well as briefly illustrated in the context of a broad discussion...
Show moreThe research conducted for this thesis explores the link between environmental ethics and household landscaping practices. The central issue of any concept of sustainability is the incommensurability of various elements that define approaches, which is why it is treated here as a politicoethical process of subjective valuation. The ethics of sustainability were delineated according to major currents in environmental ethics, as well as briefly illustrated in the context of a broad discussion of climate change and resource availability, with some examples of strategies at different institutional levels. An online survey of 87 participants provided responses about local landscaping practices, environmental concerns, environmental ethics, and landscaping aesthetics at the household level. Quantitative analyses of the data yielded significant, but lowstrength correlations between environmentally sustainable landscaping practices and environmental ethics.
