Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Biased-corrected richness estimates for the Amazonian tree flora
ter Steege, Hans; Prado, Paulo I.; Lima, Renato A. F. de; Pos, Edwin; de Souza Coelho, Luiz; de Andrade Lima Filho, Diogenes; Salomão, Rafael P.Made available in DSpace on 2020-12-12T01:28:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an exten...
Rarity of monodominance in hyperdiverse Amazonian forests
ter Steege, Hans; Henkel, Terry W.; Helal, Nora; Marimon, Beatriz S.; Marimon-Junior, Ben Hur; Huth, Andreas; Groeneveld, Jürgen; Sabatier, DanielMade available in DSpace on 2020-12-12T01:40:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); 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” forests are known from all of the main tropical regions. For Amazonia, we sam...

Biased-corrected richness estimates for the Amazonian tree flora
ter Steege, H.; Prado, Paulo I.; Lima, Renato A.Fde; Pos, Edwin T.; Coelho, Luiz Souza de; Lima Filho, Diógenes de Andrade; Salomão, Rafael PaivaAmazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia is best approximated by a logseries with aggregated individuals,...
