vegetation management goals are to be met. INTRODUCTION This paper will discuss the characteristics that make riparian zones in general extremely important ecosystems, and more specifically the riparian areas along the Colorado River from Glen Canyon Dam to Lake Mead. I will describe the processes that affect the structure and function of riparian areas, as well as the effects riparian vegetation has on other biotic and abiotic components of the system. I will also describe the historical composition

have developed postmechanistic agricultural ideas to humane and environmentally conscious food production. To offer a greater philosophical view, Aldo Leopold’s, “The Land Ethic” reorients ethics to view human beings as members of a much larger biotic community. These speakers all act on different interrelated topics to preserve nature and provide for human interest and longevity. The industrial revolution was a turning point in history that paved the way for industrial, technological, and cultural

rhizosphere of a variety of host plants. Several abiotic factors such as oxygen, temperature, specific carbon and nitrogen sources, and microelements have been identified to influence antibiotic production by bacteria biocontrol agents. Among the biotic factors that may play a determinative role in antibiotic production are the plant host, the pathogen, the indigenous microflora, and the cell density of the producing strain. This review presents recent advances in our understanding of antibiotic

Paper II: Biological Study 1. Abstract 2. Introduction In recent years, stable isotope records in speleothems (i.e., calcium carbonate deposits found in caves) have become more and more important as proxies of past climate variability (e.g., Spotl and Mangini (2002), Fleitmann et al. (2004), Harmon et al. (2004)). Speleothems, whiczare found in most continental areas provide high resolution records and can be precisely dated by U-series (Scholz and Hoffmann (2008))
