Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Nutrient content and redistribution in leaves of Hevea brasiliensis and Pinus oocarpa /
Concentração e redistribuição de nutrientes em folhas de Hevea brasiliensis e Pinus oocarpa

Semina: Ciências Agrárias, 2000
The content of macronutrients (N, P, K, Ca, Mg, and S) and nutrient redistribution were evaluated in leaves of two species, an 8 years old angiosperm (Hevea brasiliensis) and a 25 years old a gymnosperm (Pinus oocarpa), both cultivated on an eutrophic ...

Metabolism of Acetate in Hevea brasiliensis [PDF]

Nature, 1957
THERE is now considerable evidence to show that the synthesis of isoprenoid compounds in both plants and animals may proceed by the utilization of acetate as the sole primary carbon source1,2, and that the pathways by which the isoprenoid monomer is derived from acetate may have a number of carboxylate intermediates in common, for example, ββ′-dimethyl
