Fig. 8: An example network of interacting species in the Tangled Nature model.
From: Information dynamics and the emergence of high-order individuality in ecosystems
The size of the species nodes (green) in the network represents the population of the species (ni). The species influence each other using positive (red) and negative (blue) links. The strength of the influence is denoted next to the edges. We use the total population of the example ecosystem (N = 475) and the standard parameters (μ = 1/143 and k = 33) to calculate fitness and reproduction probability for a few species. The fitness calculation is explicitly shown for Species 4, which gets positive and negative influences from species 2 and 1, respectively.
