Tree growth strategies are linked to BVOC emissions
A new study by Robin et al. shows: tree growth strategies influence BVOC emissions in the Amazon, with surprising differences between isoprene and monoterpene producers.

Alike but different: Analyzing isomeric BVOC in the Amazonian atmosphere
Scientists measured carbonyl compounds in the atmosphere of the Amazon rainforest with the adopted instrumentation to separate aldehydes and ketones. They made some unexpected discoveries, showing studying the variety of carbonyl compounds separately is extremely worthwhile.
Chasing down OH with the help speech recognition techniques
Direct measurements of OH radicals are rare and difficult to achieve. However, since they react with BVOCs, Ringsdorf et al. inferred them from isoprene measurements at ATTO. To do so, they applied a technique called ‘Dynamical Time Warping’ from the field of speech recognition. Akima Ringsdorf et al. published the study “Inferring the diurnal variability of OH radical concentrations over the Amazon from BVOC measurements” Open Access in Nature Scientific Reports.
Biological and environmental factors regulating isoprene emissions
Eliane Gomes Alves and her colleagues measured isoprene emissions at the ATTO 80-meter tower across three years to better understand how these emissions vary seasonally and under extreme climatic conditions like El Niño events. They also looked into which biological and environmental factors regulate the emission of isoprene to the atmosphere.
BVOC emissions across the seasons in the Amazon
BVOC emissions in the Amazon have been studied for decades, but we still don’t fully understand when and under what conditions tree species or even individual trees emit more or fewer isoprenoids. To address this, Eliane Gomes Alves and her colleagues measured isoprenoid emission capacities of three Amazonian hyperdominant tree species.
