Dominance of neotropical tree communities by a few species is widely documented, yet the different pathways that Amazonian plants follow to achieve dominance remain poorly understood. Here, we used 503 forest inventory plots (93,719 individuals ≥ 2.5 cm diameter, 2,609 species) to explore the relationships between local abundance, regional frequency, and spatial aggregation of dominant species across habitats in western Amazonia. Contrary to the well-supported abundance-occupancy relationship, we found that among dominant Amazonian tree species, there is a strong negative relationship between local abundance and regional frequency/spatial aggregation across habitat types. Our findings suggest an ecological trade-off whereby dominant species can allocate resources to being locally abundant (local dominants) or regionally widespread (widespread dominants), but rarely both (oligarchs). Given the importance of dominant species as drivers of diversity and ecosystem functioning, unraveling different modes of dominance is a research priority to direct conservation efforts in Amazonian forests.
