Basin-wide variation in tree hydraulic safety margins predicts the carbon balance of Amazon forests

JV Tavares, RS Oliveira, M Mencuccini… - Nature, 2023 - nature.com
Tropical forests face increasing climate risk,, yet our ability to predict their response to
climate change is limited by poor understanding of their resistance to water stress. Although …

CE Doughty, DB Metcalfe, CAJ Girardin, FF Amézquita… - Nature, 2015 - nature.com
In 2005 and 2010 the Amazon basin experienced two strong droughts, driven by shifts in the
tropical hydrological regime possibly associated with global climate change, as predicted by …

Differences in xylem and leaf hydraulic traits explain differences in drought tolerance among mature Amazon rainforest trees

TL Powell, JK Wheeler, AAR de Oliveira… - Global Change …, 2017 - Wiley Online Library

Amazonia trees have limited capacity to acclimate plant hydraulic properties in response to long‐term drought

PRL Bittencourt, RS Oliveira… - Global Change …, 2020 - Wiley Online Library
The fate of tropical forests under future climate change is dependent on the capacity of their
trees to adjust to drier conditions. The capacity of trees to withstand drought is likely to be …

Embolism resistance drives the distribution of Amazonian rainforest tree species along hydro‐topographic gradients

RS Oliveira, FRC Costa, E van Baalen… - New …, 2019 - Wiley Online Library
Species distribution is strongly driven by local and global gradients in water availability but
the underlying mechanisms are not clear. Vulnerability to xylem embolism (P50) is a key trait …

CG Fontes, PVA Fine, F Wittmann… - New …, 2020 - Wiley Online Library
Amazonian droughts are increasing in frequency and severity. However, little is known
about how this may influence species‐specific vulnerability to drought across different …

Long-term decline of the Amazon carbon sink

RJW Brienen, OL Phillips, TR Feldpausch, E Gloor… - Nature, 2015 - nature.com
Atmospheric carbon dioxide records indicate that the land surface has acted as a strong
global carbon sink over recent decades,, with a substantial fraction of this sink probably …
