Pterocarpus angolensis DC and Bobgunnia madagascariensis (Desv.) J. H. Kirkbr. & Wiersema are two hardwood species found in Miombo woodland. Crown size, being closely related to the photosynthetic capacity of a tree, is an important parameter in studies of the growth of individual trees. In this sense, the present study aimed to study the morphometric relationships of P. angolensis and B. madagascariensis a...
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES; This study was developed with aim of applying the modeling biometric of open-grown trees and under competition in Araucaria Forest. Data were collected in three cities in southern Brazil: Canoinhas (SC), Lages (SC) and São Francisco de Paula (RS). In eleven chapters were introduced studies for evaluating the growth space, the dimensional chara...
REGULAÇÃO DA ESTRUTURA DIAMÉTRICA DE UMA FLORESTA DE MIOMBO USANDO O MÉTODO DE LIOCOURT EM MOÇAMBIQUE Este trabalho teve como objetivo aplicar o método de De Liocourt na regulação da estrutura diamétrica de uma floresta de Miombo no distrito de Mocuba, na região central de Moçambique, a fim de subsidiar ações de regulação do corte de madeira e manejo. O estudo foi realizado em uma área de 4,0 ha, dividida em 16...
O presente estudo teve por objetivo avaliar a dinâmica da distribuição diamétrica e produção de Eucalyptus grandis W. Hill em diferentes idades e espaçamentos. Os dados são provenientes de parcelas permanentes nas regiões Centro-Oriental Rio-Grandense e Metropolitana de Porto Alegre, RS. A função de Weibull com dois parâmetros foi usada para representar a dinâmica da distribuição diamétrica no tempo. Os parâmet...
Reliable biomass data are very important in the evaluation of ecosystems, and help in understanding the contribution of forests in climate change. Variables that describe the size of the tree, like diameter and height are directly associated with biomass, which allows the use of regression models to estimate this element. Therefore, this study aimed to estimate by regression models, the biomass of different com...
The present study aimed to develop a mathematical model to describe annual periodic percentage increment in basal area of Araucaria angustifolia trees with data collected from increment cores extracted radially from the trunk at breast height of 109 trees distributed in a large diameter range. Dendrometric and morphometric attributes were tested by multiple linear regressions as independent variables and their ...
The influence of morphometric and dendrometric variables in periodic increase in basal increment area was measured on individual trees of Araucaria angustifolia (Bertol.) Kuntze in Lages, Santa Catarina having as objectives to select a model to estimate the total height, the diameter of the crown, to compare methods for the calculation of crown projection area, to model morphometric relations as a function of d...
