Selection Principles for Gaia
R. Arthur, A. Nicholson
The Gaia hypothesis considers the life-environment coupled system as a single entity that acts to regulate and maintain habitable conditions on Earth. In this paper we discuss thre…
An Entropic Model of Gaia
Rudy Arthur, Arwen Nicholson
We modify the Tangled Nature Model of Christensen et. al. so that the agents affect the carrying capacity. This leads to a model of species-environment co-evolution where the syste…
