Degree of seed desiccation sensitivity of the Amazonian palm Oenocarpus bacaba depends on the criterion for germination [PDF]
Acta Amazonica, 2021 Across the seed-seedling transition, several germination criteria are used in studies of palm-seed germination. In Oenocarpus bataua, these criteria have differential tolerance to thermal stress.

Radiocarbon estimates of age and growth for a dominant Amazon palm species
Biotropica, Volume 55, Issue 1, Page 7-12, January 2023., 2023 We used destructive sampling to assess 14C‐calibrated age and growth of five individuals of Oenocarpus bataua Mart. (ARECACEAE) from 7.35‐21.6 m of total height. The largest individual was 59‐years old. Age decreased from the collar to the top of the aboveground stem and was positively correlated with number of leaf‐scars and height.

The fate and transit time of carbon in a tropical forest
Journal of Ecology, Volume 109, Issue 8, Page 2845-2855, August 2021., 2021 The transit time distribution quantifies the time it takes for photosynthates to appear in the respiration flux. For a tropical forest in Colombia, it predicts that 50% of fixed carbon is respired in <0.5 years, and 95% in <69 years. Editor's Choice Abstract Tropical forests fix large quantities of carbon from the atmosphere every year; however, the ...

Relieving efforts in palm‐tree tissue sampling for population genetics analyses
Ecology and Evolution, Volume 11, Issue 12, Page 7946-7950, June 2021., 2021 This study tests root tissue viability as an alternative nucleic acid source (root vs. leaf) and explores different protocols (tissue storage and DNA purification methods) to obtain high‐quality DNA samples. Results showed the effective potential of using root tissue as an alternative source, which could facilitate populations sampling of palm‐tree ...

CERNE, 2023 Background: Patauá (Oenocarpus bataua Mart.) is a palm tree belonging to the botanical family Arecaceae that occurs throughout the Amazon. Like açaí, an edible pulp is extracted from its fruits, remaining a fiber-rich waste. Revealing the potential of such raw or thermochemically modified fibers for producing bioproducts is a novelty in the literature.
