Abstract

Any given ecosystem includes macro- and micro-organismal ecology. I examine the concept of stability and its meaning in these two size scales. Historically, the stability concept follows species population dynamics and equilibrium. In micro-ecology, however, classification is rare and, in the majority of cases, not possible. Therefore, the microbial taxonomic composition is regarded in a nonspecific way, as opposed to animals and plant communities. Such different consideration leads to the emphasis on functional stability in micro-ecology versus the structural in macro-ecology. I discuss the implication of these differences in meanings and the possibilities of integrating them.
