A new study by Robin et al. reveals that isoprene emissions are associated with mechanical or chemical defenses vary between the different leaf phenological types in the central Amazon rainforest.
Lange et al. analyzed dissolved organic matter (DOM) in terra firme and white sand soils in the Amazon to learn about the potential limitations of the important nutients phosphorous, nitrogen and sulfur in the different forest and soil types prevalent across the Amazon rainforest.
Luciane Reis and her colleagues now performed a new study at the ATTO site that shows that gust fronts can also cause large jumps in carbon dioxide concentrations. But what are the sources of this carbon-dioxide-rich air?
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.
Atmospheric aerosol particles are essential for the formation of clouds and precipitation, thereby influencing the Earth’s energy budget, water cycle, and climate. However, the origin of aerosol particles in pristine air over the Amazon rainforest during the wet season is poorly understood. A new study reveals that rainfall regularly induces bursts of newly formed nanoparticles in the air above the forest canopy.
