TL;DR: Five terrestrial biosphere models evaluated against measurements from two large-scale Amazon drought experiments predicted declines in autotrophic respiration under prolonged drought in contrast to measured increases at one of the sites, and three key findings indicate critical areas for future research and model development.

TL;DR: Maintaining forest ecosystem integrity may require significant strengthening of forest conservation on private property, which can in part be accomplished by leveraging existing policy mechanisms.

TL;DR: It is found that most DGVMs poorly represented the annual cycle of gross primary productivity (GPP), of photosynthetic capacity (Pc), and of other fluxes and pools, and that models generally overestimated observed seasonal net ecosystem exchange (NEE) and respiration (Re) at equatorial locations.

TL;DR: In this article, the authors used a network of eddy covariance towers in Brazil coupled with ancillary measurements to address two main questions: first, how do mechanisms of water supply (indicated by root depth and groundwater) and vegetation water demand (defined by stomatal conductance and intrinsic water use efficiency) control evapotranspiration (E) along broad gradients of climate and vegetation from equatorial Amazonia to Cerrado, and how do these inferred mechanisms of supply and demand compare to those employed by a suite of ecosystem models?

TL;DR: The LBA Data Model Intercomparison Project (LBA-DMIP) uses a comprehensive data set from an observational network of flux towers across the Amazon, and an ecosystem modeling community engaged in ongoing studies using a suite of different land surface and terrestrial ecosystem models to understand Amazon forest function.
