Heterogeneity promotes first to second order phase transition on flocking systems
Leandro Guisandez, Gabriel Baglietto, Alejandro Rozenfeld
We have considered a variation of the Vicsek model with vectorial noise where each one of the agents have their own noise amplitude normally distributed around a mean value, , w…
Network analysis identifies weak and strong links in a metapopulation system
Alejandro F. Rozenfeld, Sophie Arnaud-Haond, Emilio Hernandez-Garcia +3
The identification of key populations shaping the structure and connectivity of metapopulation systems is a major challenge in population ecology. The use of molecular markers in t…
Evolutionary and Ecological Trees and Networks
E. Hernandez-Garcia, E. A. Herrada, A. F. Rozenfeld +5
Evolutionary relationships between species are usually represented in phylogenies, i.e. evolutionary trees, which are a type of networks. The terminal nodes of these trees represen…
Clone size distributions in networks of genetic similarity
E. Hernandez-Garcia, A. F. Rozenfeld, V. M. Eguiluz +2
We build networks of genetic similarity in which the nodes are organisms sampled from biological populations. The procedure is illustrated by constructing networks from genetic dat…
Spectrum of genetic diversity and networks of clonal organisms
Alejandro F. Rozenfeld, Sophie Arnaud-Haond, Emilio Hernandez-Garcia +4
Clonal organisms present a particular challenge in population genetics because, in addition to the possible existence of replicates of the same genotype in a given sample, some of…
Dynamic Critical approach to Self-Organized Criticality
Karina Laneri, Alejandro F. Rozenfeld, Ezequiel V. Albano
A dynamic scaling Ansatz for the approach to the Self-Organized Critical (SOC) regime is proposed and tested by means of extensive simulations applied to the Bak-Sneppen model (BS)…
