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...
Resilience of savanna forest after clear-cutting in the cerrado-amazon transiti...
Matias Reis, Simone; Schwantes Marimon, Beatriz; Marimon-Junior, Ben Hur; Gomes, Letícia; Morandi, Paulo Sérgio; Galindo Freire, Edson; Lenza, EddieThe dynamics of the natural process of recuperation of the structure and diversity of native vegetation following anthropogenic disturbance has been the subject of a great deal of controversy in restoration ecology research. The present study evaluates the natural regeneration of savanna forest (cerradão) 32 and 36 years after the clear-cutting of the vegetation. We compared species diversity, and the structure...
Evaluation of temporal variation in functional characteristics of arboreal spec...
Zilli, Giovana; Marimon, Beatriz Schwantes; Carvalho, Marco Antônio Camillo de; Sobral, Fernando Landa; Marimon-Junior, Ben HurThis study investigated the possibility of temporal variation in functional characteristics of arboreal species in three Cerrado vegetation physiognomies. We analyzed 195 species in total, including 88 in typical cerrado, 89 in cerradão and 105 in gallery forest, with 87 species common in at least two physiognomies. The study was based on lists provided by floristic and phytosociological surveys conducted over ...
Resiliência de um cerradão submetido a perturbações intermediárias na transição...
Elias, Fernando; Marimon, Beatriz Schwantes; Gomes, Letícia; Forsthofer, Mônica; Abreu, Mariângela Fernandes; Reis, Simone Almeida; Lenza, EddieO objetivo do presente estudo foi testar a hipótese de que remanescentes de florestas, mesmo em pequenas unidades de conservação e sujeitos a perturbações intermediárias, são resilientes. Para isso, as distribuições de diâmetros e alturas da comunidade e das espécies mais abundantes de um cerradão (14°42’02,3”S e 52°21’02,6”W) foram analisadas e comparadas em intervalos de dois a três anos em um período de oito...
