“…Newton et al (2011) states that understanding the relationships between genetic, morphological, and environmental factors, with the production of non-timber products, is key to creating sustainable extraction protocols for resources. This knowledge is particularly important for copaiba oleoresin, since commercial production is a relatively recent practice, and technical and scientific studies on the production process and sustainable management are at an early stage (Klauberg, Vidal, Rodriguez, & Diaz-Balteiro, 2014). The ability to estimate yield of copaiba oleoresin is important for planning and managing production.…”

El objetivo de este estudio fue investigar la relación entre las variables dendrométricas y del suelo con el rendimiento de aceite de Copaifera spp. y ajustar una ecuación para predecir la productividad en bosque primario. En el área de la investigación, 30 árboles de Copaifera spp. fueron seleccionados como muestras para la extracción del aceite por un período de 24 horas, con el uso de la barrena con 1,91 cm (3/4"). Además, fueron colectadas informaciones sobre el tamaño de los árboles y las características del suelo superficial en los alrededores de cada árbol. Se aplicó el análisis de componentes principales para verificar la relación de las variables con el rendimiento de aceite y, posteriormente, fue ajustada una ecuación para predecir este rendimiento mediante análisis de regresión. La única variable relacionada con el rendimiento de aceite fue la altura del fuste, y fue selecionada como el modelo que presentó mejor coeficiente de determinácion (0,84) y error típico de estimación (13,11%). Por lo tanto, se concluyó que el rendimiento del aceite de Copaifera spp. en bosque primario tiene una correlación positiva y significativa con la altura del fuste, mientras que las otras variables dendrométricas y del suelo superficial no presentaron correlación significativa con el rendimiento de aceite.

“…Recent research examines larvicidal activity of copaíba against the Aedes aegypti mosquito, responsible for transmission of dengue fever, yellow fever, and the Zika virus (Mendonça et al 2005), while other studies focus on the oil's potential use in treating cutaneous lesions caused by leishmaniasis (Oliveira dos Santos et al 2011). Copaíba oil has also been identified as a potential biofuel, which has stimulated studies on factors affecting oil productivity (Newton et al 2011), optimal harvest cycles (Klauberg et al 2014), and sustainable harvesting methods (Medeiros and Vieira 2008).…”

This article analyzes ritualized prescriptions for harvesting oleoresin or “oil” from the copaíba tree in Brazil. These harvesting prescriptions involve increasingly complex attributions of mind to the copaíba tree itself. The copaíba tree is widespread throughout the Americas, and for centuries has been well-known for the medicinal oil that can be extracted from its trunk. In Brazil, contemporary knowledge of the copaíba tree is bound up with colonial history and what were often destructive extractivist economies. Whereas historical accounts of the copaíba tree are often limited to mechanistic descriptions for extracting oil, this article examines attributions of mind that harvesters make to the copaíba tree. These attributions can be read from procedures for extracting oil. Such procedures are concerned with moon cycles, tree marking, sexual activity, and gaze. The article shows that such prescriptions have a wide transregional and interethnic distribution, from the Amazon Basin in northern Brazil to the Atlantic Forest on Bahia’s southern coast. New evidence from southern Bahia also involves prescriptions concerning speech and naming, which presuppose that the copaíba tree is sensitive to intentionality and human language. These mind attributions are inferred through pragmatic analysis of the (ontological) presuppositions that are embedded by harvesting prescriptions. The contribution concludes with reflections on the implications of this presuppositional analytic approach for debates concerned with animism and the “ontological turn.”

“…The absence of any reliable data throughout the time of some of the key variables (mushroom prices, biomass price, yield harvested annually, etc.) meant that a non deterministic environment was not contemplated, following other works associated with non-timber forest products (Aldea et al 2014;Klauberg et al 2014).…”

“…This approach is widely used in forestry studies, mainly when timber is considered in the analysis (Diaz-Balteiro et al 2014b), and it can be considered as a net present value maximization logic. However, sometimes variations are introduced in cases of assessment of other non-timber forest products (Klimas et al 2012;Klauberg et al 2014). The mathematical expression of the LEV, following (Diaz-Balteiro et al 2014b), is summarized in the following equation: (1)…”

In a previous study, we determined the impact of these treatments on diversity and production of fungal 2006) or other non-timber forest products (Klauberg et al 2014). According to some authors, this strategy is the optimal policy for any type of natural resource (Romero 2012).…”
