  • Biological invasion in soil: complex network analysis 

    Perez-Reche, Francisco J.; Taraskin, Sergei N.; Neri, F. M.; Gilligan, Christopher A.; Costa, Luciano da F.; Viana, M. P.; Otten, Wilfred; Grinev, D. (Institute of Electrical and Electronics Engineers, 2009-07)
    A network model for soil pore space is developed and applied to the analysis of biological invasion of microorganisms in soil. The model was parameterized for two soil samples with different compaction (loosely and densely ...
  • Complexity and anisotropy in host morphology make populations less susceptible to epidemic outbreaks 

    Perez-Reche, Francisco J.; Taraskin, Sergei N.; Costa, Luciano da F.; Neri, Franco M.; Gilligan, Christopher A. (The Royal Society, 2010-07)
    One of the challenges in epidemiology is to account for the complex morphological structure of hosts such as plant roots, crop fields, farms, cells, animal habitats and social networks, when the transmission of infection ...
  • Epidemics in networks of spatially correlated three-dimensional root-branching structures 

    Handford, Thomas P.; Perez-Reche, Francisco J.; Taraskin, Sergei N.; Costa, Luciano da F.; Miazaki, Mauro; Neri, Franco M.; Gilligan, Christopher A. (The Royal Society, 2011-03)
    Using digitized images of the three-dimensional, branching structures for root systems of bean seedlings, together with analytical and numerical methods that map a common susceptible–infected–recovered (‘SIR’) epidemiological ...
  • Prominent effect of soil network heterogeneity on microbial invasion 

    Perez-Reche, Francisco J.; Taraskin, Sergei N.; Otten, Wilfred; Viana, M. P.; Costa, Luciano da F.; Gilligan, Christopher A. (American Physical Society, 2012)
    Using a network representation for real soil samples and mathematical models for microbial spread, we show that the structural heterogeneity of the soil habitat may have a very significant influence on the size of microbial ...
  • Resilience of soil to biological invasion: analysis of spread on networks 

    Otten, Wilfred; Grinev, Dmitri V.; Perez-Reche, Francisco J.; Neri, Franco; Costa, Luciano da F.; Biana, Marcel; Gilligan, Christopher A.; Taraskin, Sergei N. (International Union of Soil Sciences, 2010-08)
    A network model for soil pore volume is presented and applied to the analysis of biological invasion of microorganisms. The pore geometry of two soils with a relatively high or low bulk density were quantified with the ...
