โœฆ Synopsis

We have numerically examined more than one million Large Complex Systems (LCS) of interacting variables (interpretable as interacting populations) governed by Generalized Lotka-Volterra Equations (GLV), with self-regulation term. The scope was to have some insight on the stability-complexity relationship.

We considered systems of prey-predator type, and we gave appropriate rules for constructing the model systems, rules that specify the behaviour of model systems in order to put them near the biological reality.

The results show, among other things, a strict correlation between the stability and the prey-predator ratio (which, in our model, uniquely determines the connectedness of the system).

The paper attempts to answer an outstanding question in theoretical ecology whether structural complexity is essential for dynamical complexity to exist. Advances in dynamical systems theory and their application to ecosystem analysis has enabled us to have a better grasp of the concept of dynamical
