Here, we used 503 forest inventory plots (93,719 individuals ≥2.5 cm diameter, 2609 species) to explore the relationships between local abundance, regional frequency and spatial aggregation of dominant species in four main habitat types in western Amazonia. Although the abundance-occupancy relationship is positive for the full dataset, we found that among dominant Amazonian tree species, there is a strong negative relationship between local abundance and regional frequency and/or spatial aggregation across habitat types. Our findings suggest an ecological trade-off whereby dominant species can be 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, unravelling different dominance patterns is a research priority to direct conservation efforts in Amazonian forests. date: 2023-12-18 date_type: published publisher: Wiley official_url: http://dx.doi.org/10.1111/ele.14351 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2136575 doi: 10.1111/ele.14351 lyricists_name: Disney, Mathias lyricists_id: MIDIS56 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Ecology Letters issn: 1461-023X citation: Matas-Granados, L; Draper, FC; Cayuela, L; de Aledo, JG; Arellano, G; Saadi, CB; Baker, TR; ...
