Variação espacial e temporal da biomassa arbórea viva em 64 km² de floresta de ...
Castilho, Carolina Volkmer deA variação espacial e temporal nas estimativas de biomassa arbórea viva acima do solo (AGLB) e suas relações com solo e topografia (altitude e inclinação do terreno) foram investigadas em parcelas permanentes distribuídas sistematicamente sobre 64 km², na Reserva Florestal Adolpho Ducke, Manaus, Amazonas. No total, foram instaladas 72 parcelas compridas (250 m) e estreitas (40 m), que seguiram as curvas de níve...

Climate seasonality limits leaf carbon assimilation and wood productivity in tr...
Wagner, Fabien H.; Hérault, Bruno; Bonal, Damien; Stahl, Clément; Anderson, Liana Oighenstein; Baker, Timothy R.; Sebastian Becker, GabrielThe seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy p...
Decomposition rates of coarse woody debris in undisturbed Amazonian seasonally ...
Barbosa, Reinaldo Imbrozio; Castilho, Carolina Volkmer de; Oliveira Perdiz, Ricardo de; Damasco, Gabriel; Rodrigues, Rafael; Fearnside, Philip MartinEstimates of carbon-stock changes in forest ecosystems require information on dead wood decomposition rates. In the Amazon, the lack of data is dramatic due to the small number of studies and the large range of forest types. The aim of this study was to estimate the decomposition rate of coarse woody debris (CWD) in two oligotrophic undisturbed forest formations of the northern Brazilian Amazon: seasonally floo...
