The main motivation for forming the Plant Physiologist website is to create tools for scientists working in our field and related areas. | Born at 411 ppm
@bioprotocolbyte paper. We present instructions for adapting two LI-6800 to simultaneously measure adaxial and abaxial gas exchange. We included details of the apparatus, scripts, and how to estimate the boundary layer conductance for this setup

Release: StomaAI (SAI)
StomaAI (SAI) is a third-party app for auto-measuring stomatal density and pore features (width, length and area) from microscope images with human-level accuracy via deep computer vision.

@pepcanadell@prabir_patra It is really shocking.
Thanks for sharing.
Here a comparison in the last 850,000 years. The red dot is an arbitrary day in December 1980 for reference between graphs.
Human activity has triggered an overwhelmingly rapid increase in the atmospheric [CO₂], noticeable in our lifetime, e.g. Darwin was born at 284 ppm, R. Franklin at 302 ppm and today we are at 419 ppm. What was the [CO₂] when you came into the World?

Release: Stomatal density repository
We are starting with a collection of 384 species. The repository is always growing and we welcome anyone sharing their published information. To include your data, contact us.

@FXPicoMercader The idea is to generate a repository with multiple entries for the same species (references), including variations on growth conditions, environmental conditions, lab, field, etc. In practice, any publication containing stomatal density data.
@ClaudioMonteza @odealab Were you discussing microscopy or stomatal density?
This picture is a section of the abaxial surfaces of a Capsicum annuum leaf.
"…they turn the standard method for calculating stomatal conductance and intercellular CO2 concentration from gas exchange measurements on its head."
Red light shines a path forward on leaf minimum conductance 👇

Commentary by @LucasCernusak @mdekauwe82
Release of a self-developed add-on for LI6800. The add-on includes calculations of gas exchange parameters accounting for small fluxes as presented by Márquez, Stuart-Williams, and Farquhar (2021) (MSF).

Paper accepted in @NewPhyt. Our paper discusses the adaxial/abaxial cuticular conductance (gcw), presents a technique to estimate gcw and an app to help with the calculations (see @P_Physiologist)

Release of gcwCi web-app
The web-app gcwCi helps to estimate the cuticular conductance to water of a leaf surface using normal gas exchange parameters, requiring as an input a known CO2 concentration within the leaf (ci).
