In their new paper Needham, et al. compare field-based data from @STRI_Panama’s Barro Colorado Island 50-ha plot with FATES simulations to benchmark growth/mortality rates & better represent crown damage in vegetation models: doi.org/10.1111/gcb.16…

Crown damage accounts for 23% of canopy biomass turnover in tropical forests and is a strong predictor of tree mortality. 🌴 Read how tree crown damage impacts carbon cycling and canopy structure in this new @GlobalChangeBio study >>> ow.ly/9o1X50JYAag

Are remote sensing super sites a thing? Thinking field stations/sites where multiple remote sensing data are captured at similar extents and multiple grains and time periods?

The leaves were collected for a @NASA grant that will use @ISS_Research data with forest inventory data, the SCOPE model, and, yes, leaf measurements, to better understand tropical forest response to drought. Last week was our practice week at SERC! On to @stri_panama and BCI!

Do you want to measure features of canopy leaves--real canopy leaves? Amazing week last week with the super team of @albert_loren working with @DeLeavesDrone at @SmithsonianEnv in the @ForestGEO plot!

Lots of ideas, new collaborations & friends during an amazing week discussing #tropicaltreemortality with experts from different forest plot networks Thank you all! Stay tuned for more 🌳

I noticed this in our water table data at SERC, Edgewater MD. Great to see this confirmed and advanced.

@Seanscience1 I'll have to read up on this though, as I was blown away by this statement "Mitochondrial processes seem distinctly less important for overall respiration than the oxidative pentose phosphate pathways in chloroplasts and the cytosol"

I don’t quite understand this. I hope to. But it also seems important. Funny how that works. This goes into my “need to read the paper and a lot of Wikipedia” folder.

Another facet, and feedback, of the climate crisis - @davbauman took us into the thicket of details for Science in Action later today bbc.co.uk/programmes/w3c…
David Bauman@davbauman

Our new study has just been published in @Nature! We find a marked increase in tree mortality in the tropical moist forests of #Australia in the past decades, consistent across many species and sites. The results point at #ClimateChange as the most likely driver.

This is an important message for those of us that use model output to contextual user our regional ecological projections. Averaging model output can include a long tail of poorer predictions (the hotter models).
