Amazon palm biomass and allometry

Allometric Equations for Estimating Biomass of Euterpe precatoria, the Most Abundant Palm Species in the Amazon

Allometric models to estimate biomass components such as stem mass Ms, foliage mass Ml, root mass Mr and aboveground mass Ma, were developed for the palm species Euterpe precatoria Mart., which is the most abundant tree species in the Amazon. We harvested twenty palms including aboveand below-ground parts in an old growth Amazonian forest in Brazil. The diameter at breast height D ranged from 3...

Oil Palm Biomass Fibres and Recent Advancement in Oil Palm Biomass Fibres Based Hybrid Biocomposites

Arbuscular mycorrhizal fungi alter plant allometry and biomass-density relationships.

BACKGROUND AND AIMS Plant biomass-density relationships during self-thinning are determined mainly by allometry. Both allometry and biomass-density relationship have been shown to vary with abiotic conditions, but the effects of biotic interactions have not been investigated. Arbuscular mycorrhizal fungi (AMF) can promote plant growth and affect plant form. Here experiments were carried out to ...

Asháninka Palm Management and Domestication in the Peruvian Amazon

Palms are a natural resource that has been abundantly used by Amerindians for centuries. Only a few palm domestications have been reported in the American tropics, where there is great diversity of the Arecaceae family. We report the results of a survey combining ethnobotanical and ecological methods to study the past and present management and distribution of palms by the Asháninka indigenous ...

Is oil palm the next emerging threat to the Amazon?

The Amazon Basin appears poised to experience rapid expansion of oil palm agriculture. Nearly half of Amazonia is suitable for oil palm cultivation, and Malaysian corporations are now moving aggressively into the region to establish new plantations. Strong economic incentives for a major Amazonian oil palm industry are likely, given growing global demands for edible oils, oil-based products, an...
