Hypothesis
Does hybridization occur between the army ant species Dorylus molestus and Dorylus wilverthi in East Africa?
Conclusion
Hybridization and gene-flow between the two army ant species D. molestus and D. wilverthi has occurred, and mating between the two forms continues to regularly produce hybrid workers.
Supporting Evidence
- Hybrid workers were found to be a significant proportion of individuals in the study.
- Different species were not recovered as monophyletic, indicating gene flow.
- Microsatellite data showed distinct genetic clusters corresponding to morphological forms.
Takeaway
Some army ants can mix and have babies that are a mix of two different types, which is surprising because they usually control who gets to mate.
Methodology
The study used morphology, mitochondrial DNA sequences, and nuclear microsatellites to investigate hybridization.
Potential Biases
Potential biases in sampling locations and methods could affect the results.
Limitations
The study may not account for all ecological factors affecting hybridization and gene flow.
Participant Demographics
The study focused on army ants from various populations in East Africa, particularly Kakamega Forest.
