Hypothesis
Where are the geographical centres of diversification in the Mexican tropical dry forest?
Conclusion
The study found that only a few areas in the Mexican tropical dry forest have historically functioned as major engines of diversification, while vast areas have acted as diversity sinks.
Supporting Evidence
- Only a few areas in the Mexican tropical dry forest have functioned as major engines of diversification.
- Vast areas have historically acted as diversity sinks, generating few or no extant Bursera lineages.
- Long-term preservation of biodiversity may be enhanced by incorporating knowledge of diversification sources into conservation decisions.
Takeaway
Some places in Mexico help create new species, while others just keep the ones that are already there. We need to protect the places that make new species.
Methodology
The study used a molecular phylogeny of the genus Bursera and current species distribution data to identify areas of diversification.
Limitations
The study's historical reconstructions may not fully account for species displacement over time.
