Ecological networks and their fragility
TLDR
E ecological networks, in which species are linked together, either directly or indirectly through intermediate species, have well defined patterns that both illuminate the ecological mechanisms underlying them and promise a better understanding of the relationship between complexity and ecological stability.

TLDR
The results suggest that ecological networks are very robust against random removals but can be extremely fragile when selective attacks are used, and have important consequences for biodiversity dynamics and conservation issues, current estimations of extinction rates and the relevance and definition of keystone species.
Information Theory of Complex Networks: On Evolution and Architectural Constraints
TLDR
It is shown that real networks are clustered in a well-defined domain of the entropy- noise space and that optimally heterogeneous nets actually cluster around the same narrow domain, suggesting that strong constraints actually operate on the possible universe of complex networks.
Least effort and the origins of scaling in human language
TLDR
This article explains how language evolution can take advantage of a communicative phase transition and suggests that Zipf's law is a hallmark of symbolic reference and not a meaningless feature.
Topological Vulnerability of the European Power Grid under Errors and Attacks
TLDR
With the ever-growing demand for power and reliability, actual planning strategies to increase transmission systems would have to take into account this relative increase in vulnerability with size, in order to facilitate and improve the power grid design and functioning.
A Model of Large-Scale proteome Evolution
TLDR
This work presents a simple model of proteome evolution that is able to reproduce many of the observed statistical regularities reported from the analysis of the yeast proteome, and suggests that the observed patterns can be explained by a process of gene duplication and diversification that would evolve proteome networks under a selection pressure.
Two Regimes in the Frequency of Words and the Origins of Complex Lexicons: Zipf’s Law Revisited*
TLDR
It is made evident that word frequency as a function of the rank follows two different exponents, ˜(-)1 for the first regime and ™(-)2 for the second.
Hierarchical Small Worlds in Software Architecture
TLDR
The final outcome of software evolution is a small world, hierarchical class diagram with well-defined statistical properties, irrespective of the specific features of each system analyzed.
Habitat Fragmentation and Extinction Thresholds in Spatially Explicit Models
TLDR
The dynamics of a metapopulation balanced by local colonization and extinction by means of the cellular automaton formalism is introduced and the existence of extinction thresholds when a given fraction of habitat is destroyed is reported.
