El aguaje es una palmera de alto valor comercial con importancia ecológica y social en la Amazonía Peruana. La tala excesiva de los individuos femeninos para el aprovechamiento de los frutos ha generado que la cosecha se realice cada vez a mayor distancia de los centros poblados y ha desencadenado la degradación y bajo estado de conservación de los aguajales en bosques naturales. El presente estudio tuvo como objetivo evaluar cómo los pobladores se vienen adaptando a la degradación del recurso, a través de la implementación de técnicas de aprovechamiento sostenible de frutos de aguaje. Aplicamos encuestas semi-estructuradas a 35 cosechadores de aguaje, evaluamos 17 áreas de aprovechamiento y acompañamos a 8 cosechadores en el aprovechamiento de los frutos de aguaje de 16 individuos adultos. Los resultados muestran que los pobladores del distrito de Jenaro Herrera han implement...

The buriti is a palm of high commercial value, with ecological and social importance in the Peruvian Amazon. The excessive felling of the female individuals for the use of the fruits has caused that the fruit harvest is carried out at greater distances from the population centres and has triggered the degradation and low state of conservation of the natural palm swamps. The objective of this study was to evaluate how the inhabitants are adapting to the degradation of the resource, through the implementation of techniques of sustainable use of buriti fruits. We applied semi-structured surveys to 35 aguaje harvesters, evaluated 17 harvesting areas and accompanied 8 harvesters in the use of the buriti fruits of 16 adult individuals. The results show that the inhabitants of the district of Jenaro Herrera have implemented harvesting techniques that prevent the death of female plants less than...

In this study, we generated information on the structural characteristics and reproductive phenology of aguaje in six plantations from 11,6 to 17 years old established in the Jenaro Herrera Research Centre, Loreto, Peru. We observed and measured plant survival, structural characteristics, and phenology. The results showed that plant survival ranged from 66% to 96%. The majority of the variables did not show an increase with the age of the plantation, except for the mean stem height and total height, which were higher in the 17‑year‑old plantation than in the younger plantations. The reproductive stage of plants began at 6‑7 years with the flowering of a few individuals and showing an increase in the number of flowering plants in the plantations each year. The flowering and fruiting of aguaje plants occurred annually with synchrony in the flowering of male and female plants. However...

Nállarett, conocida en varios paı́ses de forma cariñosa como Gigi, era una gran botánica y cientı́fica, además de ser una persona dulce, empática, creativa y brillante. Ella deja un gran legado cientı́fico en sus docenas de artı́culos, sus miles de especı́menes botánicos colectados y sus descripciones de varias especies nuevas para la ciencia. Será recordada por todos los botánicos que cruzan caminos con Caraipa davilae y Compsoneura nallarettiana, ambas especies endémicas del Perú, nombradas en su honor. Nállarett era una especialista y apasionada en bosques de arena blanca, hábitats de suelos pobres dentro de la cuenca amazónica que para ella resultaron áreas fértiles para estudiar la evolución de las maravillosas plantas que los habitan. Igualmente, deja un gran legado humano por su bella forma de ser, su generosidad y su sonrisa luminosa, mar...

We studied the genetic variability of Dipteryx ferrea shihuahuaco in seven natural populations from the Peruvian Amazon using nine microsatellite loci. The results showed a high genetic diversity shown by the high polymorphism (total alleles = 135, mean alleles per locus = 15 ± 6 alleles) and allelic richness (Macuya = 11 and Iñapari = 8, maximum and minimum allelic richness, respectively). The analysis of principal components showed a strong overlap among the populations, which added to the low values of interpopulation genetic distance (from 0.07 to 0.10), reveals a high genetic similarity among populations. The dendrogram based on the genetic distance of Shared Allele showed populations clustered in three main groups, the first formed by Manu and Iñapari populations (group A, bootstrap = 91%), the second by Contamana and Macuya (group B, 60%), and the third by Tamaya, Santa Clara e...
