Eco-evolutionary agriculture: Host-pathogen dynamics in crop rotations

Fig 3

Only ecological vs. eco-evolutionary dynamics of host-pathogen interaction.

a) Ecological dynamics, without pathogen evolution. Dynamics between seasons are represented, with infection starting at t = 0 (as in Fig 2a). b) The pathogen population is homogeneous, due to the absence of mutation. c) Eco-evolutionary dynamics with pathogen virulence evolution. Dynamics between seasons are represented, with infection starting at t = 0. Due to pathogen evolution (with μ = 0.1), the impact of the infection in the last cash seasons provokes higher host density loss, compared to a). d) Time evolution of pathogen shows that the relative abundance of fitter strains—in darker colours—increases along seasons. In both b) and d), relative abundances of the pathogen strains are plotted.
