In the context of a recent massive increase in research on plant root functions and their
impact on the environment, root ecologists currently face many important challenges to keep …

Plant water uptake from the soil is a crucial element of the global hydrological cycle and
essential for vegetation drought resilience. Yet, knowledge of how the distribution of water …

Dryland ecosystems may be especially vulnerable to expected 21st century increases in
temperature and aridity because they are tightly controlled by moisture availability. However …

Water stable isotopes (18O and 2H) are widely used as ideal tracers to track water through
the soil and to separate evaporation from transpiration. Due to the technical developments in …

A frequently expressed viewpoint across the Earth science community is that global soil
moisture estimates from satellite L‐band (1.4 GHz) measurements represent moisture only …

The relationship between plant diversity and productivity in grasslands could depend, partly,
on how diversity affects vertical distributions of root biomass in soil; yet, no prior study has …

Global circulation models and empirical evidence suggest that precipitation events are likely
to become more extreme across much of the globe,. As most plant roots are in shallow …

Drylands occur worldwide and are particularly vulnerable to climate change because
dryland ecosystems depend directly on soil water availability that may become increasingly …

In this study, we explored how rainfall manipulation influenced competitive interactions
between grasses and juvenile trees (small nonreproductive trees capable of resprouting) in …

Savannas cover a significant fraction of the Earth's land surface. In these ecosystems, C3
trees and C4 grasses coexist persistently, but the mechanisms explaining coexistence …
