    We determine the density profile and velocity of invasion fronts in one-dimensional infinite habitats in the presence of environmental fluctuations. The population dynamics is reformulated in terms of a stochastic ...

    One of the main ecological phenomenons is the Allee effect, in which a positive benefit from the presence of conspecifics arises. In this work we describe the dynamical behavior of a population with Allee effect in a ...
  • Low dose aerosol fitness at the innate phase of murine infection better predicts virulence amongst clinical strains of mycobacterium tuberculosis 

    Cardona, Pere-Joan; Cáceres, Neus; Llopis Fuste, Isaac; Marzo, Elena; Prats Soler, Clara; Vilaplana, Cristina; García de Viedma, Darío; Samper, Sofia; López Codina, Daniel (2012-01-03)
    Article
    Open Access
    Background: Evaluation of a quick and easy model to determine the intrinsic ability of clinical strains to generate active TB has been set by assuming that this is linked to the fitness of Mycobacterium tuberculosis strain ...
