description | The microbiome can significantly impact host phenotypes and serve as an
additional source of heritable genetic variation. While patterns across
eukaryotes are consistent with a role for symbiotic microbes in host
macroevolution, few studies have examined symbiont-driven host evolution
or the ecological implications of a dynamic microbiome across temporal,
spatial or ecological scales. The pea aphid, Acyrthosiphon pisum, and its
eight heritable bacterial endosymbionts have served as a model for studies
on symbiosis and its potential contributions to host ecology and
evolution. But we know little about the natural dynamics or ecological
impacts of the heritable microbiome of this cosmopolitan insect pest. Here
we report seasonal shifts in the frequencies of heritable defensive
bacteria from natural pea aphid populations across two host races and
geographic regions. Microbiome dynamics were consistent with symbiont
responses to host-level selection and findings from one population
suggested symbiont-driven adaptation to seasonally changing parasitoid
pressures. Conversely, symbiont levels were negatively correlated with
enemy-driven mortality when measured across host races, suggesting
important ecological impacts of host race microbiome divergence. Rapid
drops in symbiont frequencies following seasonal peaks suggest microbiome
instability in several populations, with potentially large costs of
‘superinfection’ under certain environmental conditions. In summary, the
realization of several laboratory-derived, a priori expectations suggests
important natural impacts of defensive symbionts in host-enemy
eco-evolutionary feedbacks. Yet negative findings and unanticipated
correlations suggest complexities within this system may limit or obscure
symbiont-driven contemporary evolution, a finding of broad significance
given the widespread nature of defensive microbes across plants and
animals. |
