Hypothesis
More extensive sampling will reveal that the Apterostigma-associated Escovopsis are not monophyletic like their associated ant-hosts.
Conclusion
The fungus-growing ant-microbe association has a complex coevolutionary history with occasional host-switching by pathogens.
Supporting Evidence
- Escovopsis infection rates were higher in G2 and G4 colonies compared to G3 colonies.
- More than 50% of G2 and G4 colonies were infected with at least one Escovopsis type.
- Phylogenetic analysis revealed that Escovopsis lineages do not form a monophyletic clade.
Takeaway
Ants and the fungi they grow have a special relationship, but sometimes the fungi that attack them switch to different types of fungi.
Methodology
Phylogenetic analysis of Escovopsis lineages infecting Apterostigma ant gardens.
Potential Biases
Potential bias due to geographic sampling limitations.
Limitations
Limited sampling of Apterostigma-associated Escovopsis and potential biases in infection rates.
Participant Demographics
Apterostigma ant colonies from various geographic locations.
