“…in the department of Ucayali. This is a commercial species threatened by commercial overharvesting and an apparent low regeneration rate [8]. The use of tools such as MaxEnt made it possible to use large volumes of numeric and remote sensing data [31] for current and future modeling to the year 2100.…”

“…The Peruvian Amazon possesses forest species with high commercial value, such as the Dipteryx spp., also known as shihuahuaco [8] which grows up to 40 m in height and has an average diameter of 70 to 150 cm [9]. There are 12 species of Dipteryx in the world, which are mainly distributed in the Amazonian rainforests and Central America [10].…”

“…Shihuahuaco is a species widely used in the timber industry, due to its hardness, commercial value and ecological importance as a food source and habitat for many species [11,12]. However, it is currently one of the most threatened species due to illegal logging and commercial over-logging, which limits its rate of recovery [8]. In addition, these activities affected the potential distribution of this tree species' habitats throughout the Peruvian Amazon.…”

The consequences of climate change influence the distribution of species, which plays a key role in ecosystems. In this work, the modeling of the current and potential future distribution was carried out under different climate change scenarios of a tree species of high economic and commercial value, Dipteryx spp. This is a hardwood species that plays an important role in carbon sequestration, providing food and nesting for wildlife species, reaching more than 40 m in height with an average diameter of 70 to 150 cm. This species is currently threatened by overexploitation. Thirty-six bioclimatic, topographic and edaphic variables with ~1 km2 spatial resolution obtained from the WorldClim, SoilGrids and SRTM databases where used. Highly correlated variables were identified with the MaxEnt software for forecasting how the species distribution will be affected until the year 2100, according to the climate scenarios SPP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5, representing the periods 2021–2040, 2041–2060, 2061–2080 and 2081–2100, respectively. The AUC accuracy value of 0.88 to 0.89 was found for the distribution models and the highest contributing variables used were Bio 5, precipitation, Bio 2, and Bio 14. In the climate scenario SPP1-2.6 (Bio 5, precipitation and Bio 2) in 2061–2080, suitable and very suitable habitats represented 30.69% of the study area (2616 ha and 586.97 ha, respectively) and those increased by 1.75% under current climate conditions, and the suitable and unsuitable habitats represented 69.31% of the total area. The results of this research provide valuable information on the current and future distribution of the species and identify zones that can be used as the basis for the creation of conservation areas, formulation of restoration projects, reforestation and sustainable management to avoid the extinction of the species in the face of the effects of climate change.

“…It is beyond the scope of this feature to present a detailed discussion of the limitations of CITES, so we shall highlight only a few. Many species, such as shihuahuaco (Dipteryx micrantha) in Peru, where it is widely harvested to supply the international trade in parquet, are not listed (Espinosa and Valle, 2020). Domestic trade in listed species is not addressed by the Convention, although this has been addressed in resolutions that have had some impact for certain species, notably with respect to the trade in ivory and pangolins.…”

“…En Perú, la región Madre de Dios tiene como una de sus principales actividades económicas la producción de madera (Oliveira et al, 2019), destacando las especies forestales, cedro (Cedrela odorata L.) y caoba (Swietenia macrophylla King) (Espinosa & Valle, 2020). Se ha reportado que el cedro presenta un contenido de taninos del tipo hidrolizables o pirogálicos (solubles en agua) y la caoba presenta taninos condensables o catecol, que son insolubles en agua (Espinal-Corrales, 2009).…”

La industria maderera en la región de Madre de Dios, Perú, es una de las actividades económicas más importantes y produce gran cantidad de residuos, entre ellas las cortezas, fuentes potenciales de taninos. El objetivo fue extraer y caracterizar fisicoquímicamente los taninos de la corteza de caoba (Swietenia macrophylla) y cedro (Cedrela odorata) colectados de árboles maduros, en poblaciones localizadas del distrito de Tambopata - Madre de Dios. Los extractos tánicos fueron obtenidos por extracción sucesiva con solución acuosa salina, y sometidos a análisis para determinar su solubilidad, color, densidad y pruebas de identificación compuestos tánicos. Los resultados mostraron que la corteza de caoba presentó mayor concentración de taninos que la del cedro, alcanzando ambos 46% y 42%, respectivamente; además, el extracto tánico de la corteza de cedro presentó densidad de 0,972 g/mL y la de caoba un 0,976 g/mL. En conclusión, las cortezas de caoba y cedro son fuentes potenciales de taninos del tipo pirogálicos para la industria de productos naturales.
