What is the potential for synthetic biology as a way of engineering, on a large scale, complex ecosystems? Can it be used to change endangered ecological communities and rescue them to prevent their collapse? What are the best strategies for such ecological engineering paths to succeed? Is it possible to create stable, diverse synthetic ecosystems capable of persisting in closed environments? Can synthetic communities be created to thrive on planets different from ours? These and other questions pervade major future developments within synthetic biology. [...]

22 p, 3.7 MB Theoretical conditions for the coexistence of viral strains with differences in phenotypic traits : A bifurcation analysis / Nurtay, Anel (Centre de Recerca Matemàtica) ; Hennessy, Matthew G. (Universitat Autònoma de Barcelona. Barcelona Graduate School of Mathematics (BGSMath)) ; Sardanyés, Josep (Universitat Autònoma de Barcelona. Barcelona Graduate School of Mathematics (BGSMath)) ; Alsedà i Soler, Lluís (Universitat Autònoma de Barcelona. Barcelona Graduate School of Mathematics (BGSMath)) ; Elena, Santiago F. (Santa Fe Institute (USA)) ; Universitat Autònoma de Barcelona. Departament de Matemàtiques
We investigate the dynamics of a wild-type viral strain which generates mutant strains differing in phenotypic properties for infectivity, virulence and mutation rates. We study, by means of a mathematical model and bifurcation analysis, conditions under which the wild-type and mutant viruses, which compete for the same host cells, can coexist. [...]

9 p, 1.0 MB Finite-time scaling in local bifurcations / Corral, Álvaro (Centre de Recerca Matemàtica) ; Sardanyés, Josep (Barcelona Graduate School of Mathematics) ; Alsedà i Soler, Lluís (Barcelona Graduate School of Mathematics) ; Universitat Autònoma de Barcelona. Departament de Matemàtiques
Finite-size scaling is a key tool in statistical physics, used to infer critical behavior in finite systems. Here we have made use of the analogous concept of finite-time scaling to describe the bifurcation diagram at finite times in discrete (deterministic) dynamical systems. [...]

11 p, 854.8 KB Variability in mutational fitness effects prevents full lethal transitions in large quasispecies populations / Sardanyés, Josep (Universitat Pompeu Fabra) ; Simó, Carles (Universitat de Barcelona. Departament de Matemàtica Aplicada i Anàlisi) ; Martínez Barchino, Regina (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Solé, Ricard V. (Universitat Pompeu Fabra) ; Elena, Santiago F. (Universitat Politècnica de València. Instituto de Biología Molecular y Celular de Plantas)
The distribution of mutational fitness effects (DMFE) is crucial to the evolutionary fate of quasispecies. In this article we analyze the effect of the DMFE on the dynamics of a large quasispecies by means of a phenotypic version of the classic Eigen's model that incorporates beneficial, neutral, deleterious, and lethal mutations. [...]

12 p, 847.0 KB Trans-heteroclinic bifurcation : a novel type of catastrophic shift / Sardanyés, Josep (Centre de Recerca Matemàtica) ; Martínez Barchino, Regina (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Simó, Carles (Barcelona Graduate School of Mathematics)
Global and local bifurcations are extremely important since they govern the transitions between different qualitative regimes in dynamical systems. These transitions or tipping points, which are ubiquitous in nature, can be smooth or catastrophic. [...]
