Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density Open
Woody biomass in tropical trees contributes significantly to global carbon stocks; however, these stocks are increasingly affected by climate and land‐use changes. Understanding the growth mechanisms driving woody biomass production is ess…

Pantropical tree rings show small effects of drought on stem growth Open
Increasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evaluate this risk, we assessed drought impac…

Evaluating possible sources of error in tree-ring <sup>14</sup>C data using multiple trees across South America Open
A limitation in fine-tuned tree-ring radiocarbon ( 14 C) data is normally associated with overall data uncertainty. Tree-ring 14 C data variance as a result of sample heterogeneity can be reduced by adopting best practices at the time of s…

Demystifying the tropics: FTIR characterization of pantropical woods and their α-cellulose extracts for past atmospheric 14C reconstructions Open
To ensure unbiased tree-ring radiocarbon (14C) results, traditional pretreatments carefully isolate wood cellulose from extractives using organic solvents, among other chemicals. The addition of solvents is laborious, time-consuming, and c…

A novel post-1950 CE atmospheric 14C record for the tropics using absolutely dated tree rings in the equatorial Amazon Open
In this study, we present a comprehensive atmospheric radiocarbon (14C) record spanning from 1940 to 2016, derived from 77 single tree rings of Cedrela odorata located in the Eastern Amazon Basin (EAB). This record, comprising 175 high-pre…
