The Regeneration of Nature: an alternative to ecological restoration is an exploration of the human response to alterations society has imposed on natural ecosystems. Ecological restoration is the dominant response to these degraded systems that has emerged within Western, empirical thought. Restoration as it is characteristically practiced in the United States attempts to reverse human impact by returning an ecosystem to an earlier state of existence; its so called pre-disturbance condition. However, I argue that ecological restoration does not adequately address degraded ecosystems dominating today's landscape primarily because it excludes humans as an integrated part of ecosystems and it ignores the dynamic characteristics of nature. Despite the dichotomy embedded in the restoration view, humans and nature are best understood as interdependent. Therefore, those working on urban environmental issues must develop integrated solutions in which both society and nature benefit without creating negative impacts on each other. In The Regeneration of Nature: an alternative to ecological restoration , I show how the connections between science, society, and nature can be recognized as an integrated view to establish a new paradigm for positive change within communities, both natural and human. The new paradigm, which I entitle ecological regeneration, extends the interdisciplinary style of environmental research as it calls for the development, adoption, and dissemination of a truly integrated and dynamic socio-ecological model to replace the static and reductionist view that prevails within the ecological restoration model. Where restoration treats the human and natural environments as mutually exclusive, regeneration recognizes the necessity of integrating human built systems within nature and nature within built systems. By examining conceptual and practical problems within ecological restoration, my goal is to offer an ecological regeneration framework leading to theoretically better solutions with respect to society's impact on natural ecosystems. The vision I offer here of regenerating nature within the built environment is intended to help fellow scientists, non-scientists, and the general public pursue an environmentally accountable and socially responsible prospect.

Many species considered exotic, by both biological definition and social construction, have been introduced into South Florida. These species compete for resources with native species and with each other. In this study, I surveyed the John D. MacArthur Campus of Florida Atlantic University in Jupiter Florida during spring and fall of 2005 to determine the assemblage dynamics of several exotic herpetofauna species, primarily the nocturnal Wood Slave gecko (Hemidactylus mabouia), the Indo- Pacific gecko (H. garnotii), and the diurnal Cuban brown anole (Anolis sagrei). I found that the more recently established (H. mabouia) was out-competing (H. garnotii) on most of the buildings being surveyed. The study also showed that the Cuban treefrog, (Osteopilus septentrionalis) population affected the gecko populations significantly. (A. sagrei) was the primary anole found on campus, with sightings of (A. carolinensis) the native Florida green anole, being rare.

Greenways are corridors of relatively intact natural vegetation through otherwise disturbed habitat that typically connect larger protected natural areas. The establishment of greenway systems throughout the United States is a testament to the increasing recognition of the necessity to incorporate wild areas within urban and other disturbed landscapes for the sake of biological sustainability and the emotional welfare of human residents. In my thesis, I examine a local greenway in Jupiter, Florida, the Abacoa Greenway, which is both product and component of the greenway movement, a recent and revolutionary phenomenon in urban planning. I evaluate the greenway's ecology, the specific functions it serves, and its significance within the broader realm of environmental ethics. The primary protected habitats are a mixture of scrubby pine flatwoods and shallow wetland basins. The flatwoods provide important habitats for numerous native species, including the gopher tortoise (Gopherus polyphemus) and the many commensal species that live in the tortoises' burrows. The shallow wetland basins also serve a number of purposes, including a surface water management system. As a whole, the greenway is an important resource for human recreation and environmental education, including scholarly research by students and faculty at Florida Atlantic University. It serves as important link between people and nature in an urban setting where they might otherwise be completely estranged.
