~ 7% global forests is plantation (young) Young (Y) vs Old forests (O): How do water + carbon (C) processes belowground differ? Y: less streamflow & deep gw % O: higher DOC + DIC; deep roots Y&O: can have contrasting DOC CQ; consistent DIC dilution agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🌟✨New paper: Check out our New Phytologist Tansley review on how changing precipitation patterns (changes in amount, intensity, & frequency of ppt already being observed due to climate change) affect soil organic matter dynamics. nph.onlinelibrary.wiley.com/doi/epdf/10.... @ghezzehei.bsky.social

Very excited for this to come out just after presenting it at #AGU25. We show how fine root presence reveals deep root-regolith interactions more accurately than biomass, using root abundance data from 75 soil pits in many ecosystem types. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Our new research analyzing high-frequency soil moisture data from 40 NEON sites across 17 US ecoregions reveals the widespread occurrence of Preferential Flow (PF) & its drivers across continental scale environmental gradients. Published in AGU's Geophysical Research Letters doi.org/10.1029/2025...

Ubiquity and Causes of Soil Water Preferential Flow Across 17 Ecoregions
Preferential flow (PF) is ubiquitous across the USA and occurs in up to 60% of all rainfall events ≥2 mm Rainfall intensity, soil texture, and antecedent soil moisture emerge as critical in gener...

We are so excited to share the results of this work! Annalise Guthrie’s hard work demonstrates how the loss and regeneration of deep roots can change the way deep soils are structured at a continental scale. This was such a joy to work on! @agu.org agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Deep Root Loss and Regeneration in the Anthropocene Drive Continental‐Scale Changes in Deep Soil Structure
Deep root dynamics imposed by land-use change are modifying deep soil structure at the continental scale well below zones of tillage As deep roots disappear, structural unit size increases and ro...

New commentary paper out this week with @gruberte.bsky.social and Sara Warix in WRR - we argue that temperature overshoot has consequences for regional hydrology and water resources that bear consideration. agupubs.onlinelibrary.wiley.com/doi/full/10....
Drawing of the water cycle in a landscape with and without temperature overshoot. Impacts include forest cover, glacial contributions, infrastructure, geomorphology, water use for carbon dioxide removal, groundwater depletion.
