DIVERSIDADE DE ESTRATÉGIAS PRODUTIVAS EM ECONOMIAS PRIVADAS E COLETIVAS NA AMAZ...
Vieira, Timni; do Socorro da Silva, Camila de Cássia; de Andrade Rodrigues, Thayana Cristina; da Rosa, Círia CristianeEsta pesquisa teve como objetivo analisar se há diferença entre estratégias familiares de uso do solo nas diferentes formas de propriedade da terra na Amazônia, a partir de uma pesquisa com 345 entrevistados em 15 municípios no Pará. Os resultados apontaram uma maior diversificação em arranjos coletivos com a combinação “agricultura, capoeira e extrativismo florestal”. Não houve diferença na diversidade produti...
Projection model by diameter class for native forests: focus on the Weibull pro...
Mendes Nascimento, Rodrigo Geroni; Machado, Sebastião do Amaral; Figueiredo Filho, Afonso; Higuchi, NiroIn 1979 the technique of modeling diameter distributions by probabilistic functions was first applied for Hyink & Moser in forecasting growth and production of uneven aged and heterogeneous forests. However, today few studies use this method for planning the production in these forests for not knowing the operational feasibility of the technique. Therefore this paper presents a review of the characteristics...
Dendrometric relationship of Araucaria angustifolia
Mendes Nascimento, Rodrigo Geroni; Machado, Sebastião do Amaral; Figueiredo, Décio José de; Augustynczik, Alan Lessa Derci; Cavalheiro, RicardoThe objective of this research was to study the relationship between the DBH with crown diameter,stump diameter and inside bark diameter at breast height of Araucaria angustifólia (Bert.) O, Kuntze. The data from the mentioned variables came from 162 Araucaria distributed in the whole amplitude of diameter at breast height in a Mixed Ombrophylous Forest fragment with 15,24 hectares located at the Curitiba urban...
Behavior of the hypsometric relationship of Araucaria angustifolia in the fores...
Machado, Sebastião do Amaral; Mendes Nascimento, Rodrigo Geroni; Augustynczik, Alan Lessa Derci; Silva, Luís César Rodrigues da SilvaThe objective of this research was to test and select mathematics models for estimating total heigh (ht) and bole high (hb), as a function of DBH, as well as, to establish the dendrometric relationship between ht/hb. The data came from measurements of diameters (DBH), total height and bole height of all Araucaria angustifolia trees from an Ombrophylous Mix Forest fragment of 15,24 ha situated in the Botanical ...
Growth dynamics of young trees of Araucaria angustifolia and Pinus taeda
Machado, Sebastião do Amaral; Figura, Marco Aurélio; Silva, Luís César Rodrigues da; Mendes Nascimento, Rodrigo Geroni; Quirino, Sandra Mara dos SantosThe objective of this research was to investigate the monthly growth rhythm of young trees of Araucaria angustifolia and Pinus taeda throughout the vegetative year and to establish its correlation with climatic variables. Monthly measurements of diameter and total height were carried out in one stand of A. angustifolia and two of Pinus taeda. Correlation matrices among the current monthly increments and the cli...
