Rarity of monodominance in hyperdiverse Amazonian forests

摘要: Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" from all of main tropical regions. For Amazonia, we sampled occurrence monodominance massive, basin-wide database forest-inventory plots Amazon Tree Diversity Network (ATDN). Utilizing simple defining metric at least half trees ≥ 10 cm diameter belonging to one species, found only few occurrences and phenomenon was not significantly linked previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation sprouts base on roots) trait monodominance. While specific locales associations may confer considerable advantage lead its monodominance, very have these traits. Mining ATDN dataset suggests that quite rare be primarily edaphic factors.
