The old trick of never finishing the house to avoid paying property tax...

That's impressive and depressing equal measures.

Next project: translate the whole website into Spanish as well

I think it absolutely can, but one would just have to be clear that it is the heat tolerance or heat sensitivity of PSII that is being evaluated (which is exactly what fluorescence based T50 gives you), without claiming that this T50 predicts the risk of leaf death.

Storing leaf disks for 2 weeks isn't practical for high-throughput heat tolerance. It defeats the purpose of measuring fluorescence as a proxy for necrosis.
It will be important to figure out what these parameters really tell us, and which parameters are most relevant for our questions (3/3)

This graph shows the decline in Fv/Fm measured 24 hours after leaf incubation (in green), yielding a T50 of ~49.5C. But the %necrosis 14 days after incubation (in red) did not increase until temperature exceeded 53C. Fv/Fm measured after 14 days does better (2/3)

Hi Pricilla, here is a link to the PDF of the book chapter:

Yes, that's the one! A magnificent specimen. A shame that it died

It's a Ceiba pentandra that used to be the tree with the biggest crown on BCI (crown diameter >61 m), drawn with a Wacom tablet by forest giants specialist Robert van Pelt

The print version should be out in 2-3 months.
And yes, I imagine it should be an essential for any office with grad students and postdocs working on tropical ecology. If nothing else, the 2 volumes combined should provide enough height as a laptop stand!

I was just informed that we should receive chapter PDFs next week, and hopefully by that time I'll have figured out how to use DM on this platform :)

The chapter I contributed is about temperature effects on the trees of BCI. The electronic book should be downloadable, but let me know if you want a copy of my chapter.
