13 p, 3.3 MB About ghost transients in spatial continuous media / Calsina i Ballesta, Àngel (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Cuadrado Gavilán, Sílvia (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Vidiella, Blai (Centre de Recerca Matemàtica) ; Sardanyés, Josep (Centre de Recerca Matemàtica)
The impact of space on ecosystem dynamics has been a matter of debate since the dawn of theoretical ecology. Several studies have revealed that space usually involves an increase in transients' times, promoting the so-called supertransients. [...]

8 p, 1.6 MB Social copying drives a tipping point for nonlinear population collapse / Oro, Daniel (Centre d'Estudis Avançats de Blanes. Laboratori d'Ecologia Teòrica i Computacional - CSIC) ; Alsedà i Soler, Lluís (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Hastings, Alan (University of California.

Sudden changes in populations are ubiquitous in ecological systems, especially under perturbations. The agents of global change may increase the frequency and severity of anthropogenic perturbations, but complex populations' responses hamper our understanding of their dynamics and resilience. [...]

Tomás (Universitat Politècnica de Catalunya. Departament de Matemàtiques) ; Sardanyés, Josep (Barcelona Graduate School of Mathematics (BGSMath))
Discrete-time dynamics, mainly arising in boreal and temperate ecosystems for species with non-overlapping generations, have been largely studied to understand the dynamical outcomes due to changes in relevant ecological parameters. [...]

13 p, 8.1 MB Dynamical mechanism behind ghosts unveiled in a map complexification / Canela Sánchez, Jordi (Universitat Jaume I. Institut Universitari de Matemàtiques i Aplicacions de Castelló) ; Alsedà i Soler, Lluís (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Fagella Rabionet, Núria (Universitat de Barcelona. Departament de Matemàtiques i Informàtica) ; Sardanyés, Josep (Centre de Recerca Matemàtica)
Complex systems such as ecosystems, electronic circuits, lasers, or chemical reactions can be modelled by dynamical systems which typically experience bifurcations. It is known that transients become extremely long close to bifurcations, also following well-defined scaling laws as the bifurcation parameter gets closer the bifurcation value. [...]

Complex dynamical fluctuations, from intracellular noise, brain dynamics or computer traffic display bursting dynamics consistent with a critical state between order and disorder. Living close to the critical point has adaptive advantages and it has been conjectured that evolution could select these critical states. [...]

25 p, 3.5 MB Bivalent chromatin as a therapeutic target in cancer : An in silico predictive approach for combining epigenetic drugs / Alarcón Cor, Tomás (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Sardanyés, Josep (Centre de Recerca Matemàtica) ; Guillamon, Antoni (Centre de Recerca Matemàtica) ; Menendez, Javier A. (Institut d'Investigació Biomèdica de Girona)
Tumour cell heterogeneity is a major barrier for efficient design of targeted anti-cancer therapies. A diverse distribution of phenotypically distinct tumour-cell subpopulations prior to drug treatment predisposes to non-uniform responses, leading to the elimination of sensitive cancer cells whilst leaving resistant subpopulations unharmed. [...]

23 p, 2.1 MB Population dynamics of synthetic terraformation motifs / Solé, Ricard (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona)) ; Montañez, Raúl (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona)) ; Duran-Nebreda, Salva (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona)) ; Rodriguez-Amor, Daniel (Massachusetts Institute of Technology) ; Vidiella, Blai (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona)) ; Sardanyés, Josep (Centre de Recerca Matemàtica)
Ecosystems are complex systems, currently experiencing several threats associated with global warming, intensive exploitation and human-driven habitat degradation. Because of a general presence of multiple stable states, including states involving population extinction, and due to the intrinsic nonlinearities associated with feedback loops, collapse in ecosystems could occur in a catastrophic manner. [...]

11 p, 4.5 MB Noise-induced bistability in the fate of cancer phenotypic quasispecies : a bit-strings approach / Sardanyés, Josep (Centre de Recerca Matemàtica) ; Alarcón Cor, Tomás (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
Tumor cell populations are highly heterogeneous. Such heterogeneity, both at genotypic and phenotypic levels, is a key feature during tumorigenesis. How to investigate the impact of this heterogeneity in the dynamics of tumors cells becomes an important issue. [...]

Semiarid ecosystems are threatened by global warming due to longer dehydration times and increasing soil degradation. Mounting evidence indicates that, given the current trends, drylands are likely to expand and possibly experience catastrophic shifts from vegetated to desert states. [...]
