Definission: There is no evidence that the organism produces compounds (allelochemicals) that influence the growth, survival, and reproduction of other organisms.
Definission: Open shrubland and savanna in the north of Brazil and in Colombia and Venezuela, with low, sparse vegetation growing on sandy soils mostly within terra firme land in the Amazon. It can be of the ‘forested’ type, similar to a gallery forest, ‘wooded’ where the trees are shorter, and finally ‘grassy-woody’, where it occurs in wet plains near rivers and lakes. Amongst the more frequent plant families are the Arecaceae, Bromeliaceae, Clusiaceae, Humiriaceae, Marantaceae, Meliaceae and Rapateaceae.

Definission: Amazonian forest where the soil remains either wet or flooded for most of the year, often associated to sandy soils. When compared to Terra Firme and Várzea Inundated Forests it is generally the less tall of them.
