The most common definitions of biological diversity focus on state variables, such as genes, species, and communities, but processes, such as gene flow, survivorship, competition, and energy flow, ultimately determine the nature of these state variables and are critical to the survival of biological diversity itself (Noss 1990). The relationship between biological diversity, ecological process, and human activities is now a critical concern for scientists and policy makers (Lubchenco et al. 1991).
