“…Wild populations of M. flexuosa (aguaje or buriti) are an important source of edible palm fruit in north-western South America, next only to cultivated Bactris gasipaes (Peters et al, 1989;Penn, 2008). Mauritia flexuosa has a wide distribution in north-western South America and is also very common in Brazil.…”

“…The NTFP are used for various purposes by human societies, mainly by the poorest ones (Shackleton et al, 2011(Shackleton et al, , 2018, serving as food, fuel, fiber, building materials, rubber production, medicine, dye for fabrics, among other purposes (Melese, 2016;Penn, 2008;Zubair et al, 2021). One of the main NTFPs in the Amazon is andiroba oil, historically used by traditional populations and very popular throughout the region, which is extracted from the seeds of trees known as andirobas.…”

Comprehending the size distribution within a population and grasping its connection to tree maturation (onset of reproductive phase) is pivotal for formulating sustainable management strategies and conserving numerous tree species. The objective of this study was to compare the structure and probability of fruit production of Carapa guianensis in two types of forest (varzea, or floodplain, vs. terra firme, or upland) in the northeastern Amazon, Brazil. The study was conducted in four permanent plots of 300 × 300 m (two for each type of forest). All individuals ≥10 cm in diameter at breast height (DBH) were mapped and measured for DBH, height, and canopy characteristics (shape and position), and liana infestation. Sixty‐seven trees were inventoried in the upland forest and 297 in the floodplain forest. The trees were larger in the upland (33.36 ± 1.84 cm) than in the floodplain (21.92 ± 1.5 cm) and more than half (56%) of the upland trees and more than two thirds (67%) of floodplain trees were reproductive. The minimum diameter for fruit production in the floodplain (10.2 cm of DBH) was more than two times smaller than in the upland (25.5 cm of DBH). The probability of fruit production of a tree of the same size was twice as high in the floodplain compared with the upland, and trees with rounded canopies had a higher probability of fruit production in the upland. Our results showed that the probability of fruit production can be modeled with variables of tree size and canopy shape, and that intrinsic factors of the forests influence the reproductive maturity of C. guianensis which presents greater precocity and productive potential of seeds in the estuarine floodplain forest of the Amazon River.Abstract in Portuguese is available with online material.

“…M. flexuosa is dioecious, meaning that individual palms are either males (pollen producers) or females (fruit producers) (Holm et al, 2008). Among numerous anthropogenic threats, palm swamps have been degraded by the destructive method of harvesting M. flexuosa fruit by felling female individuals (Penn, 2008;Horn et al, 2018). Horn et al (2018) estimated that between 2012 and 2013 approximately 114,000 palms were felled.…”
