And yes, there are comics, courtesy of Jason Hupp. Gorgeous botanical imagery will show up in later chapters.

This comprehensive, humorous (hopefully), and well-illustrated (definitely) guide gets into the physics, engineering, and biology underlying our favorite plant physiology measurements, in a way that we hope will be easily approachable and accessible. Dare I say, you might even enjoy reading it...

Definitely a recommended read for any exchanger of gases working with stressed and low-flux material. This summarizes many important considerations and measurement assumptions underlying the models of stomatal conductance and other derived parameters which are implemented in gas exchange systems.

Excited to share our paper with Anna Gardner and @florianabusch.bsky.social in Plant Ecophysiology!🌿

We review challenges in interpreting plant stress responses using gas exchange data, offer solutions to improve accuracy and discuss gaps in our current knowledge.

$Detailed representation of H2O gas exchange (left) and CO2 gas exchange (right) at the adaxial (upper) and abaxial (lower) leaf surfaces in an amphistomatous leaf. This panel illustrates the separate gas exchange processes for each leaf surface, which can be measured individually if the upper and lower cuvettes are analysed separately—though this setup is not common in commercial gas exchange systems. Stomatal, cuticle, and boundary layer resistances are depicted for both surfaces, along with the mole fractions of water vapour and CO2.$

Congratulations to our PhD student Georgia, who passed her viva yesterday with (very) minor corrections! All while being interrupted by the fire alarm… Thanks to Julian Hibberd and Tracy Lawson for being excellent examiners! 🌱🌿

New review paper out:

We outline the uncertainties/ambiguities that are present when estimating mesophyll conductance (gm).

We also explore whether genetically engineering higher gm will lead to greater crop yields.
