Hi all! If you are a PhD or soon to be PhD looking for a postdoc in plant thermotolerance, I would love to discuss project ideas for the University of Utah Wilkes Center Postdoc Fellowship, app due late Jan 2026!
Msg me if there is interest. Tnx!

Using a unique long-term field experiment, we show that chronic (20 years!) drought reduces ecosystem CO2 uptake and persistently shifts soil fungal and bacterial communities, but that shifts in plant communities determine ecosystem CO2 fluxes. 🧵

We found hydrochemical spatial variations are indicative of increasing evaporative concentration and decreasing streamflow with decreasing altitude. Also major ions and stable isotopic data suggest groundwater as a uniform source feeding streamflow.🏞️💦

Happy to see our paper out! we analyzed the spatio-temporal variability of water stable isotopes and hydrochemical properties in the semiarid catchment of the Huaco river of the Sierras Pampeanas, Argentina. Lead by postdoc M. Macchioli-Grande.

Check out our recent paper on xylem and soil water extractions via centrifugation from urban space of Texas, lead by Erica Almance & Ricardo Sánchez-Murillo. We discuss on the value of this technique for water extractions, as well as on organic contamination. onlinelibrary.wiley.com/doi/10.1002/...

Climate warming is not a recent phenomenon; it has had detectable impacts on plants for at least 134 years!
