The roles of dispersal limitation and pre-adaptation in shaping <i>Paraburkholderia</i> endosymbiont frequencies in social amoeba communities.

ABSTRACT: Endosymbiotic interactions have long played fundamental roles in shaping the evolution and diversification of eukaryotes. However, we still have a limited understanding of how ecological processes govern the distribution of endosymbionts that are still segregating in host populations. To contribute to this understanding, here, we use the interactions between Paraburkholderia endosymbionts and their dictyostelid social amoeba hosts as a model system to investigate the role of dispersal, a fundamental ecological process, in shaping the distribution and evolution of endosymbiotic interactions. We first found that patterns of endosymbiont diversification were highly biogeographic, suggesting a significant degree of dispersal limitation. We then experimentally mediated the dispersal of s
