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...

Moonlight, Peter W.; Banda-R, Karina; Phillips, Oliver L.; Dexter, Kyle G.; Pennington, R. Toby; Baker, Tim R.; Lima, Haroldo C. de; Fajardo, LaurieUnderstanding of tropical forests has been revolutionized by monitoring in permanent plots. Data from global plot networks have transformed our knowledge of forests’ diversity, function, contribution to global biogeochemical cycles, and sensitivity to climate change. Monitoring has thus far been concentrated in rain forests. Despite increasing appreciation of their threatened status, biodiversity, and importanc...

Amazon tree dominance across forest strata
Draper, Frederick C.; Costa, Flavia R. C.; Arellano, Gabriel; Phillips, Oliver L.; Duque, Alvaro; Macía, Manuel J.; ter Steege, Hans; Asner, Gregory P.Made available in DSpace on 2021-06-25T10:27:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); The forests of Amazonia are among the most biodiverse plant communities on Earth. Given the immediate threats posed by climate and land-use change, an improved understanding of how this extraordinary biodiversity is spatially organized...
Long-term thermal sensitivity of Earth’s tropical forests
Sullivan, Martin J. P.; Lewis, Simon L.; Affum-Baffoe, Kofi; Castilho, Carolina; Costa, Flávia; Sanchez, Aida Cuni; Ewango, Corneille E. N.The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important p...

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...
Competition influences tree growth, but not mortality, across environmental gra...
Rozendaal, Danaë M.A.; Phillips, Oliver L.; Lewis, Simon L.; Affum-Baffoe, Kofi; Alvarez, Esteban; Andrade, Ana C.S.; Aragao, L. E.O.C.Competition among trees is an important driver of community structure and dynamics in tropical forests. Neighboring trees may impact an individual tree’s growth rate and probability of mortality, but large-scale geographic and environmental variation in these competitive effects has yet to be evaluated across the tropical forest biome. We quantified effects of competition on tree-level basal area growth and mor...
