Abstract
- Abstract Tropical and subtropical trees provide key ecosystem services but are facing global population decline due to logging, habitat degradation, land conversion, and climate change. Vatica guangxiensis used to be a characteristic timber species of China's tropical forests but is now terminally endangered (280 individuals) and fragmented into three relictual populations in southwest China. Generating genome‐wide DNA for ∼82% of all living tree individuals of this species complex, we found evidence for a late Pliocene division into two species‐level lineages that have not had gene flow for approximately 3 million years. All three relictual populations exhibited a loss of genetic diversity and recent bottlenecks. In addition, forward simulations indicated a likely population collapse in all three populations within the next century. Our study generates a model framework for the integration of genomic evidence—including evolutionary history, current genetic variation, and future projections—into conservation planning.
