Instructive surprises in the hydrological functioning of landscapes

JW Kirchner, P Benettin… - Annual Review of Earth …, 2023 - annualreviews.org
Landscapes receive water from precipitation and then transport, store, mix, and release it,
both downward to streams and upward to vegetation. How they do this shapes floods …

Spatiotemporal origin of soil water taken up by vegetation

G Miguez-Macho, Y Fan - Nature, 2021 - nature.com
Vegetation modulates Earth's water, energy and carbon cycles. How its functions might
