Tropical Alder (Alnus acuminata) tree rings.
Excited to have this paper out showing a strong coupling between Central American tree-ring oxygen isotopes and ocean–atmosphere dynamics (interbasin SST gradients, ITCZ, CLLJ... ). Many thanks to all co-authors!

#Tree stems accumulate biomass by adding volume of certain density. Which factor is more important?
Using tropical #treering data we found: diameter increment explains biomass growth at short term; wood density at long term.🌎🌐🍁

Abstract. Xylem conduits widen with distance from the treetop (dtreetop), counteracting most of the resistance to water transport which accumulates with tr

🪵 Diameter drives short-term biomass gains, but long-term carbon storage hinges on wood density, especially in humid forests. To improve accuracy, biomass models should account for radial wood density variation and climate ☁️

Diameter growth is an important and good indicator of forest carbon production. However, size-related changes in wood density, which are usually neglected, are critical for accurate short- and long-t...
