Preferences for horizontal transfer partners among habitats. The colored point corresponds to the bacteria from the different habitats (red : ubiquitous, cyan : water, green : insects, yellow: amoeba, pink: intracellular vertebrates, purple: extracellular vertebrates, blue: water and soils, brown: soils). The traits are colored according to the habitats of studied bacteria and their thickness is proportional to the amount of genes exchanged
