Tridge summary
Researchers from Embrapa, the Federal University of Acre, and American universities have identified factors that influence the production of chestnut tree urchins, such as relief, changes in climate, and air vapor pressure. Their findings show that a more severe dry season and lower levels of phosphorus and potassium minerals in the soil result in reduced fruit production. Understanding these factors is important for planning extractivist activities and improving the genetic management of chestnut trees.

Factors such as relief, variation in air vapor pressure and changes in climate influence the production of chestnut tree urchins (Bertholletia excelsa Bonpl.). The discovery is part of research carried out by scientists from Embrapa, the Federal University of Acre (Ufac) and the North American universities of Alabama (UA) and Florida (UFL). For ten years, they monitored and recorded the natural production of fruits in 258 centennial chestnut trees distributed in two communities in the state of Acre: Chico Mendes Extractive Reserve and Chico Mendes Agroextractive Settlement Project. The work was published by the journal Nature, in the article Comparative models disentangle drivers of fruit production variability of an economically and ecologically important long-lived Amazonian tree. The sale of the tree's product, the Amazon nut (or Brazil nut, or even Brazil nut), supplements the income of thousands of families in the North Region. The team applied a mathematical model that ...
