GPA and FCD were supported by a grant from the John D. and Catherine T. MacArthur Foundation and the Leonardo DiCaprio Foundation. Plot installations, fieldwork and botanical identification by the authors and colleagues has been supported by several grants including a NERC PhD studentship to FCD (NE/J50001X/1), an ‘Investissement d’avenir’ grant from the Agence Nationale de la Recherche (CEBA, ref. ANR-10- LABX-25-01), a Gordon and Betty Moore Foundation grant to RAINFOR, the EU’s Seventh Framework Programme (283080, ‘GEOCARBON’) and NERC Grants to OLP (Grants NER/A/S/2000/0053, NE/B503384/1, NE/F005806/1, and a NERC Postdoctoral Fellowship), and a National Geographic Society for supporting forest dynamics research in Amazonian Peru (grant #5472-95).

dc.description.abstractThe forests of western Amazonia are among the most diverse tree communities on Earth, yet this exceptional diversity is distributed highly unevenly within- and among communities. In particular, a small number of dominant species account for the majority of individuals while the large majority of species are locally and regionally extremely scarce. By definition, dominant species contribute little to local species richness (alpha diversity), yet the importance of dominant species in structuring patterns of spatial floristic turnover (beta diversity) has not been investigated. Here, using a network of 207 forest inventory plots, we explore the role of dominant species in determining regional patterns of beta diversity (community-level floristic turnover and distance-decay relationships) across a range of habitat types in northern lowland Peru. Of the 2031 recorded species in our dataset, only 99 of them accounted for 50% of individuals. Using these 99 species it was possible to reconstruct the overall features of regional beta diversity patterns, including the location and dispersion of habitat types in multivariate space, and distance-decay relationships. In fact, our analysis demonstrated that regional patterns of beta diversity were better maintained by the 99 dominant species than by the 1932 others, whether quantified using species abundance data or species presence/absence data. Our results reveal that dominant species are normally common only in a single forest type. Therefore, dominant species play a key role in structuring Western Amazonian tree communities, which in turn has important implications, both practically for designing effective protected areas, and more generally for understanding the determinants of beta diversity patterns.
