The Keystone Species Theory Ecological communities are highly complex. In any ecological community there are hundreds is not thousands of organisms interacting in a wide range of dynamic relationships. The visual representation of these relationships is known as biodiversity( Krohne 704). Biodiversity is vital to life on this planet but it is currently in a period of decline. For example, in “Getting to Solutions at Worldfuture 2009” by Ann Fenney states, “…the world’s biodiversity is decreasing, and extinction levels are rising”( Fenney 59). In order to potentially stop or reverse this trend it is necessary to understand some of the key determinants of biodiversity structure. One way of trying to understand the nature of biodiversity it...The end:
