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.16318
![Quoted excerpt from Needham, et al.: “Crown damage and damage-driven mortality are important processes shaping forest structure and response to disturbance. Despite this, crown damage is rarely represented in vegetation models. We introduce a crown damage module into the vegetation demographic model FATES [Functionally Assembled Terrestrial Ecosystem Simulator] and find that damage itself alters demographic rates, the canopy structure of the forest, and the competitive dynamics of PFTs [Plant functional types].” In bottom left corner, ForestGEO logo.](https://pbs.twimg.com/media/FY2GvZlVsAAsyEq.jpg?name=small&format=webp)

Crown damage accounts for 23% of canopy biomass turnover in tropical forests and is a strong predictor of tree mortality. 🌴

Transcriptomically speaking, what makes a #liana (climbing vine) a liana? Let's read... @ForestGEO @Seanscience1 @Sammyjo_13 @Nate_G_Swenson journals.biologists.com/bio/…

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 🌳

Another facet, and feedback, of the climate crisis - @davbauman took us into the thicket of details for Science in Action later today

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.

I'm thrilled to present our new study in @GlobalChangeBio (in OA), on the effects of #climate on #tree growth across an elevation gradient in the #tropical moist #forests of Australia. 🌳🌤️🌿
