FOREST FRAGMENT GROUPING ANALYSIS UNDER SELECTIVE LOGGING IN AMAZONIAN BIOME
Rocha, Karen Janones da; Souza, Édila Cristina de; Favalessa, Cyro Matheus Cometti; Caldeira, Sidney Fernando; Rodrigues, Silvo AlvesABSTRACT: The aim of this study was to analyse the existence of floristic groups in Seasonal Semi-deciduous Forest fragments under the effects of selective logging located in Tapurah-MT. The given clusters were allocated and measured, and each one had five subunits of 500 m². For each sampling unit, all of the arboreal and shrub species with a diameter at breast height (DBH) equal to or greater than 10 cm were ...
Estruturação da produção de Tectona grandis Linn f. em Mato Grosso
Favalessa, Cyro Matheus ComettiThe need to improve the management of forest resources, the growth modeling is fundamental to suport the decision-making regarding to the forest planning and yield structuring. The general goal int his research was to develop a diameters distribution model and yield structure of Tectona grandis in Mato Grosso. The research was developed in a forest stand of Tectona grandis in Nossa Senhora do Livramento, in the...
Effect of selective logging on floristic and structural composition in a forest...
Rocha, Karen Janones da; Souza, Édila Cristina de; Favalessa, Cyro Matheus Cometti; Caldeira, Sidney Fernando; Martinez, Diego TyszkaThis study was conducted in one region of a Seasonal Semideciduous Forest located in Tapurah (Mato Grosso State, Brazil) with the aim of studying its floristic and structural composition. The fixed area method was applied to 10 × 250 m clusters, allocating and measuring five clusters with five subunits of 500 m² each. Species with a diameter at breast height greater than or equal to 10 cm were considered, and ...

O presente estudo teve como objetivo aplicar e selecionar modelo de volume com e sem casca para Qualea paraensis Ducke e Erisma uncinatum Warm., a partir de dados de um inventar...
Non-segmented and segmented taper models to Tectona grandis in center-southern ...
Favalessa, Cyro Matheus Cometti; Ubialli, Jaime Antônio; Caldeira, Sidney Fernando; Drescher, RonaldoThe aim of this study was to compare the accuracy of the non-segmented polynomial models of Fifth degree and Hradetzky from 1976 and the segmented models of Max and Burkhart from 1976 and Clark et al. from 1991, in estimating diameters along the stem of Tectona grandis L.f., with adjustments for the full set of data and by diameter class in a 16 years old stand in the center–southern region of Mato Grosso State...
Assortment of Tectona grandis in south–central region of Mato Grosso, Brazil
Favalessa, Cyro Matheus Cometti; Ubialli, Jaime Antônio; Caldeira, Sidney Fernando; Drescher, Ronaldo; Acosta, Fidel CándanoThe aim of this study was to compare the accuracy of volume estimative along the stem of Tectona grandis L. f obtained by adjustment of non–segmented and segmented polynomial models, for a forest stand in South–Central region of Mato Grosso State, Brazil. Data from rigorous tree scaling of Tectona grandis, using One hundred and fourtheen trees were measured by Hohenadl method, using 16 sections. The non–segment...
