Hypothesis
How did Pleistocene climatic changes affect the distribution and genetic diversity of the millipede genus Narceus?
Conclusion
The study found that climatic changes during the Pleistocene significantly influenced the distribution and genetic diversity of Narceus, with evidence of refugial populations and post-glacial expansions.
Supporting Evidence
- The genetic structure of Narceus reflects a complex history of multiple refugia.
- Significant negative Fu's Fs values indicate rapid population expansions.
- Niche-based distribution modeling identified areas of high ecological suitability during the Pleistocene.
Takeaway
This study shows that during the last ice age, some millipedes found safe places to survive, and after the ice melted, they spread out to new areas.
Methodology
The study used mitochondrial DNA sequencing and niche-based distribution modeling to analyze genetic diversity and historical distribution patterns.
Limitations
The study may have limited sampling in some areas, which could affect the comprehensiveness of the findings.
