Death from drought in tropical forests is triggered by hydraulics not carbon starvation
Drought threatens tropical rainforests over seasonal to decadal timescales,,,, but the drivers
of tree mortality following drought remain poorly understood,. It has been suggested that …

Global convergence in the vulnerability of forests to drought
Shifts in rainfall patterns and increasing temperatures associated with climate change are
likely to cause widespread forest decline in regions where droughts are predicted to …

Drought impact on forest carbon dynamics and fluxes in Amazonia
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 …

Triggers of tree mortality under drought
Severe droughts have caused widespread tree mortality across many forest biomes with
profound effects on the function of ecosystems and carbon balance. Climate change is …

Hydraulic diversity of forests regulates ecosystem resilience during drought
Plants influence the atmosphere through fluxes of carbon, water and energy, and can
intensify drought through land–atmosphere feedback effects,–. The diversity of plant …

Drought survival of tropical tree seedlings enhanced by non-structural carbohydrate levels
Plants in most biomes are thought to be living at their hydraulic limits, and alterations to
precipitation patterns consistent with climate change trends are causing die-back in forests …

The rainforest's water pump
LEOC Aragão - Nature, 2012 - nature.com
An investigation of naturally occurring water recycling in rainforests finally marries the results
of global climate models with observations. Alarmingly, it also suggests that deforestation …

Drought–mortality relationships for tropical forests
The rich ecology of tropical forests is intimately tied to their moisture status. Multi‐site
syntheses can provide a macro‐scale view of these linkages and their susceptibility to …

Non-structural carbohydrates mediate seasonal water stress across Amazon forests
Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have
been implicated in mediating drought-induced tree mortality. Despite their significance, NSC …

Tropical tree mortality has increased with rising atmospheric water stress
Evidence exists that tree mortality is accelerating in some regions of the tropics,, with
profound consequences for the future of the tropical carbon sink and the global …
