This study analyzed the diametric distributions before and after forest management in a rainforest area of the Amazon in the Amapá State, Brazil. It aimed to understand how the diametric distribution of the forest was recovered after 27 years of forest management between 1984 and 2011. For this...

The demographic processes of a tree community, such as recruitment and mortality of individuals, significantly affect the other dynamic and structural events of forests. The objective of this research was to evaluate the recruitment and mortality rates of Araucaria angustifolia (Bertol.) Kuntze in...

Non-timber forest products (NTFPs) are a consolidated source of income and acquisition of inputs from forest environments. Therefore, the objective of this work was to carry out a collection of publications on NTFPs in Brazil, until 2019, available in the Scopus database, presenting a bibliometric...

Weibull distributions have been widely used to describe tree stem diameter distributions. However, there is a scarcity of studies that suggest the best Weibull formulation. The parameters of the Weibull distribution are usually predicted by either the parameter prediction method (PPM) or the...

The Mixed Ombrophilous Forest is one of the most threatened ecosystems in Brazil. It is thus necessary to understand its dynamics of growth over time so that sustainable use and conservation management strategies be proposed. The objective of this study is to evaluate the behavior of the diametric...

Individual tree attributes, such as stem volume and biomass, are usually predicted by using traditional field-derived allometric models. However, these models are derived from data collected from small areas and lack a level of detail of tree components (e.g., stem, branches, and leaves). Remote...

Accurate forest biomass estimates require the selection of appropriate models of individual trees. Thus, two properties are required in tree biomass modeling: (1) additivity of biomass components and (2) estimator efficiency. This study aimed to develop a system of equations to estimate young...
