Yes, many tropical trees have annual rings! Great to contribute to this global synthesis led by @pieterzuidema.bsky.social, indicating stronger droughts w climate change may shift observed more resilient responses toward more widespread decreases in productivity www.science.org/doi/10.1126/... 🧪🌾🌐
Pantropical tree rings show small effects of drought on stem growth
Increasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evalua...

A very comprehensive analysis of lagged precipitation effects in terrestrial ecosystems. Tree rings, flux, grassland ANPP, satellite remote sensing, and DGVMs. Climate memory is an important driver of global plant productivity.
He ert al. integrate ground-based observations, remote sensing and process-based models to disentangle the relative contribution of preceding-year and current-year precipitation on plant productivity and identify its predictors across biomes

Also in GCB: a meta-analysis of precipitation pulse-responses in C and water cycling (doi.org/10.1111/gcb....). *Huge* effort by @ecophysism.bsky.social. We characterized both the size of response to pulses, and also the shape (do we even see a hump?). Future C-water coupling shifts are possible 🌐🌍

Cool results from the #funpotential project presented by @mikkopel.bsky.social today at the biodivclim final event @biodiversa.eu.
They help understand how and why tree diversity can help to adapt forest to climate change.

Natural disturbances are often invoked as an argument against creating new forest reserves. But are reserves more affected by disturbances than managed forests? For C Europe the answer is no, in fact reserves have lower disturbance rate & severity than managed forests! doi.org/10.1111/1365...
