Recent studies have reported a consistent pattern of strong dominance of a small subset of tree species in Neotropical forests. These species have been called ‘hyperdominant’ at large geographical scales and ‘oligarchs’ at regional-landscape scales when being abundant and frequent. Forest community assembly is shaped by environmental factors and stochastic processes, but so far the contribution of oligarchic species to the variation of community composition (i.e. beta diversity) remains poorly known. To that end, we...
