Darwin used the metaphor of a ‘tangled bank’ to describe the complex interactions between
species. Those interactions are varied: they can be antagonistic ones involving predation, …

Fluctuations in ecological systems are known to involve a wide range of spatial and temporal
scales, often displaying self-similar (fractal) properties. Recent theoretical approaches are …

… Here, we use a protocell model (Macía & Solé 2007a) where two enzyme molecules (E) are
used as catalytic systems, transforming an external precursor R into a new molecule G. If the …

… Ricard Solé and Jordi Bascompte provide a comprehensive introduction to complex
systems theory, and ask: do universal laws shape the structure of ecosystems, at least at some …

The topology of the proteome map revealed by recent large-scale hybridization methods
has shown that the distribution of protein–protein interactions is highly heterogeneous, with …

A large number of complex networks, both natural and artificial, share the presence of highly
heterogeneous, scale-free degree distributions. A few mechanisms for the emergence of …

… Near the critical point, the system displays scale invariance: If we observe such system at
a spatial scale r, it looks the same when a larger or smaller scale is used.7 The behavior of …
