Hypothesis
Are rare Indo-Pacific Acropora species hybrids?
Conclusion
Some rare Acropora species may be less vulnerable to extinction due to their hybridization and increased genetic diversity.
Supporting Evidence
- Rare Acropora species may have increased adaptive potential due to hybridization.
- Hybridization may allow rare species to occupy atypical habitats.
- Effective population sizes for rare species are significantly smaller than census sizes.
Takeaway
Some rare corals can mix with other types, which helps them survive better than we thought.
Methodology
DNA sequence data from nuclear and mitochondrial loci were analyzed from rare and common Acropora species.
Potential Biases
Potential bias due to sampling limitations and the difficulty in distinguishing between hybridization and incomplete lineage sorting.
Limitations
The rarity of some species limited the number of samples that could be examined.
Participant Demographics
Samples included 14 rare and 8 common Indo-Pacific species of Acropora.
