Figure 2From: Horizontal gene transfer dynamics and distribution of fitness effects during microbial in silico evolutionGeneral overview of the simulated ecological setting. Microbial population evolves under a complex environment AB ("single-step" adaptation) either directly (i), or through a first step of evolution in less convoluted, but still related, environments A and B with (ii) or without (iii) the presence of HGT events.Back to article page
