Species competition: coexistence, exclusion and clustering
Emilio Hernandez-Garcia, Cristobal Lopez, Simone Pigolotti +1
We present properties of Lotka-Volterra equations describing ecological competition among a large number of competing species. First we extend to the case of a non-homogeneous nich…
Universal functions and exactly solvable chaotic systems
M. A. Garcia-Nustes, Emilio Hernandez-Garcia, Jorge A. Gonzalez
A universal differential equation is a nontrivial differential equation the solutions of which approximate to arbitrary accuracy any continuous function on any interval of the real…
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…
Simple models for scaling in phylogenetic trees
Emilio Hernandez-Garcia, Murat Tugrul, E. Alejandro Herrada +2
Many processes and models --in biological, physical, social, and other contexts-- produce trees whose depth scales logarithmically with the number of leaves. Phylogenetic trees, de…
Universal scaling in the branching of the Tree of Life
E. Alejandro Herrada, Claudio J. Tessone, Konstantin Klemm +3
Understanding the patterns and processes of diversification of life in the planet is a key challenge of science. The Tree of Life represents such diversification processes through…
Comparison between Eulerian diagnostics and finite-size Lyapunov exponents computed from altimetry in the Algerian basin
F. d'Ovidio, J. Isern-Fontanet, C. Lopez +2
Transport and mixing properties of surface currents can be detected from altimetric data by both Eulerian and Lagrangian diagnostics. In contrast with Eulerian diagnostics, Lagrang…
Diversity-induced resonance in a system of globally coupled linear oscillators
Raul Toral, Emilio Hernandez-Garcia, James D. Gunton
The purpose of this paper to analyze in some detail the arguably simplest case of diversity-induced reseonance: that of a system of globally-coupled linear oscillators subjected to…
Joint effects of nutrients and contaminants on the dynamics of a food chain in marine ecosystems
Flora S. Bacelar, Sibylle Dueri, Emilio Hernandez-Garcia +1
We analyze the joint effect of contaminants and nutrient loading on population dynamics of marine food chains by means of bifurcation analysis. Contaminant toxicity is assumed to a…
How Gaussian competition leads to lumpy or uniform species distributions
Simone Pigolotti, Cristobal Lopez, Emilio Hernandez-Garcia +1
A central model in theoretical ecology considers the competition of a range of species for a broad spectrum of resources. Recent studies have shown that essentially two different o…
