Scaling properties of protein family phylogenies
E. Alejandro Herrada, Víctor M. Eguíluz, Emilio Hernández-García +1
One of the classical questions in evolutionary biology is how evolutionary processes are coupled at the gene and species level. With this motivation, we compare the topological pro…
Top marine predators track Lagrangian coherent structures
E. Tew Kai, V. Rossi, J. Sudre +5
Meso- and submesoscales (fronts, eddies, filaments) in surface ocean flow have a crucial influence on marine ecosystems. Their dynamics partly control the foraging behaviour and th…
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…
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…
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…
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…
