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.

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.

Leaf day respiration involves multiple carbon sources and depends on previous dark metabolism Plant, Cell & Environment is an ecology journal analysing the ways plants respond to their environment including biological, physiological and ecological factors.

This book focuses on content intrinsically related to the infrastructure surrounding data analysis in R, but does not delve into the data analysis itself. A holistic workflow provides guidance on project-oriented workflows that address common sources of friction in data analysis. Personal R administration empowers R users to confidently manage their R programming environment. All is Fail showcases functions, options, and RStudio capabilities for debugging code, facilitating more efficient resolution of errant code.

"What They Forgot to Teach You About R" great ressource even for people with good experience in R and Rstudio

Embracing uncertainty: The way forward in plant fossil phylogenetics Although molecular phylogenetics remains the most widely used method of inferring the evolutionary history of living groups, the last decade has seen a renewed interest in morphological phylogenetics....

my first paper of the year (and my first ever single author paper) has been finally published!

Do you work on fossil plants? Do you feel that your phylogenies are too uncertain? Don't fear uncertainty, EMBRACE IT! 🧪🌾🌱

Fill a plant's air spaces with water and it no longer can sense the direction of light. Revelatory finding from Christian Fankhauser's lab. Power of genetics!

We introduce a mathematical model to connect innovation and obsolescence across diverse systems like economics, biology, and science. Taking the “space of the possible,” we model how it grows from innovation and decays with obsolescence.

In Neubau: Cafe Comet for amazing coffee and local feeling. La Spiga for the best pizza I ever had (and I have high standards).

Not to forget - Palmenhaus in Schönbrun Park: classic Victorian greenhouse with a nice plant collection. The parc is nice to see but not essential on a short stay. /end

For a classic Viennese coffee house: Cafe Sperl, close to the Natural History Museum. Less or no line up than the ones in the 1st district and with more locals.

Neubau (7th district): lots of nice streets to stroll and places to eat. I’m biased because I lived there. 2/.

Definitely the Natural History Museum! Been there countless times when we lived in Vienna.

Historic centre: It’s nice but there are closer neighbourhoods where you can get a better feeling of why Vienna is such a great city. 1/.

If you use the background_image() function from ggpubr (rpkgs.datanovia.com/ggpubr/refer...), you can display your ggPlantmap on top of a image. There is a small y-axis offset, but it can do the trick. I will work on implementing this function whenever I have some free time. #ggPlantmap

This paper is super super cool!! Did you know you can see the shadows of Joshua trees from Google map images? And then you can use that to estimate with pretty incredible detail the range? You can, and they did!! Check it out.
