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. [...]

15 p, 2.2 MB Trophic interactions between larger crocodylians and giant tortoises on Aldabra Atoll, western Indian Ocean, during the late pleistocene / Scheyer, Torsten M. (University of Zurich. Palaeontological Institute and Museum) ; Delfino, Massimo (Institut Català de Paleontologia Miquel Crusafont) ; Klein, Nicole (Universität Bonn. Steinmann Institut für Geologie, Paläontologie und Mineralogie) ; Bunbury, Nancy (Seychelles Islands Foundation) ; Fleischer-Dogley, Frauke (Seychelles Islands Foundation) ; Hansen, Dennis M. (University of Zurich. Zoological Museum and the Department of Evolutionary Biology and Environmental Studies)
Today, the UNESCO World Heritage Site of Aldabra Atoll is home to about 100 000 giant tortoises, Aldabrachelys gigantea, whose fossil record goes back to the Late Pleistocene. New Late Pleistocene fossils (age ca. [...]

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. [...]

12 p, 770.4 KB Active and reactive behaviour in human mobility : the influence of attraction points on pedestrians / Gutiérrez Roig, M. (Universitat de Barcelona. Departament de Física Fonamental) ; Sagarra, O. (Universitat de Barcelona. Departament de Física Fonamental) ; Oltra, Aitana (Institució Catalana de Recerca i Estudis Avançats) ; Palmer, John R. B. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bartumeus, Frederic (Centre de Recerca Ecològica i Aplicacions Forestals) ; Díaz Guilera, A. (Universitat de Barcelona. Departament de Física Fonamental) ; Perelló, J. (Universitat de Barcelona. Departament de Física Fonamental)
Human mobility is becoming an accessible field of study, thanks to the progress and availability of tracking technologies as a common feature of smart phones. We describe an example of a scalable experiment exploiting these circumstances at a public, outdoor fair in Barcelona (Spain). [...]

7 p, 705.9 KB Proximate causes of the red face of the bald uakari monkey (Cacajao calvus) / Mayor Aparicio, Pedro Ginés (Universitat Autònoma de Barcelona. Departament de Sanitat i d'Anatomia Animals) ; Mamani, Javier (Universidad Peruana Cayetano Heredia. Facultad de Veterinaria) ; Montes Aliaga, Daniel (YAVACUS, Yavarí Conservación y Uso Sostenible (Iquitos, Perú)) ; González-Crespo, C. (Universitat Autònoma de Barcelona. Servei d' Ecopatologia de Fauna Salvatge) ; Sebastián, M. A. (SAMAI (Iquitos, Perú)) ; Bowler, Mark (San Diego Zoo Global (Estats Units d'Amèrica))
In social species, such as primates, facial appearances transmit a variety of social signals. Although it is suggested that the intense red colour of the face of the bald uakari monkey might be an indicator of health, this hypothesis still has not been verified. [...]
