A geochemical model to materialize biotic regulation of the earth environment

Abstract

To discuss the possibility of biota-involved regulation of a condition of the earth, which is not a resource (e.g., temperature), it is useful to investigate "independent regulation" systems. An attempt has been made to find a mechanism to generate the selective or suppressive pressure through an independent regulation mechanism (Biotic Independent Regulation: BIR). In this brief paper, we propose a simple abstract model, which select a favorable species (or suppress an unfavorable species) without employing local effects.
