Abstract
The maximum entropy production principle (MEPP) is an important and growing area of research with significant implications for many fields of study, including ecology. Thermodynamically, an ecosystem operates in such a way as to maximize entropic production, in accordance with the second law of thermodynamics. This paper presents a general model of the observed changes in entropic production during ecological succession, beginning with emerging evidence that the climax community represents a state of maximum entropy production. We then examine the outcome of this model, which provides a new insight into the driving process, direction and seral progression observed in succession. We suggest that succession moves towards an energetic rather than a structural climax, which represents a dynamic rather than a static state. Using the maximum entropy production principle, we propose that entropic generation across a succession follows a logistic model, initially undergoing rapid increase in entropy production, before approaching an asymptote, called Smax. The underlying changes in entropy production are suggested to control seral change. This is in agreement with a growing body of literature, and provides a framework for a new understanding of succession. These findings also have significant implications for assessing anthropological impacts on ecosystems.
