These cases make me wonder about the definition of tree mortality...

[SeanMcMahon @Seanscience1]

Ugh. (this is not an 'ugh' from a tree lover, who wants trees to be happy and live long, productive lives, but a tree demographer, who wants clear, interpretable data!).

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: https://t.co/SXmlAf3zPD

Transcriptomically speaking, what makes a #liana (climbing vine) a liana? Let's read... @ForestGEO @Seanscience1 @Sammyjo_13 @Nate_G_Swenson https://t.co/pdvJ06KYu6

@jaaronhogan @albert_loren @DeLeavesDrone @SmithsonianEnv @ForestGEO I was thinking the same thing last week. Our pilots, Phd students Emmy and Charlie, would destroy a grabby game at a boardwalk arcade!

[SeanMcMahon @Seanscience1]

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!

[SeanMcMahon @Seanscience1]

@atkinsjeff @SmithsonianEnv (SERC) is close to one. @NEON_sci, Gator Eye from @ebennb, G-LiHT, Jess Parker's upfacing lidar, and now collected ISS data. Many instruments, many scales, many years. And lots of ground data through the 16 ha @ForestGEO plot.

[SeanMcMahon @Seanscience1]

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!

@DanielFZuleta Nice pool. Great group. Excited for the success!

[Daniel Zuleta @DanielFZuleta]

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.

[SeanMcMahon @Seanscience1]

@Juliaofthewoods maybe cex for labels = 0.7 and constrain the xlim and ylim?

[SeanMcMahon @Seanscience1]

@martijn_slot @martijn_slot again. I’m going to need Wikipedia. But I love the expert response.

[SeanMcMahon @Seanscience1]

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.

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).
