Stratification criteria to fit taper functions on pine boles
David, Hassan Camil; Marinheski Filho, Ataides; Pelissari, Allan; Péllico Netto, Sylvio; Araújo, Emanuel; Baum, LuizaThis paper aimed to evaluate the accuracy of taper functions fitted with and without stratification on Pinus sp. trees. Three strata were allocated using diameter at 1.3 m above the ground, artificial form factor and Schiffel’s form quotient as stratification criteria. Schöepfer, Kozak et al. Hradetzky, Garcia et al., Ormerod and Demaerchalk taper functions were tested and the one which best fitted to the total...
Padrão espacial de espécies arbóreas em fragmento de floresta estacional semide...
Araújo, Emanuel José Gomes de; David, Hassan Camil; Péllico Netto, Sylvio; Morais, Vinícius Augusto; Scolforo, José Roberto SoaresConhecer o padrão de distribuição espacial de espécies florestais é importante para compreender os processos ecológicos de uma dada comunidade. O objetivo deste trabalho foi analisar o padrão de distribuição espacial de quatro espécies de maior densidade em um fragmento florestal. Os dados de diâmetro a 1,3 m do solo (DAP), altura total e as coordenadas geográficas de todos os indivíduos arbóreos com DAP ≥ 10...
Hypsometric relation for candeia (Eremanthus erythropappus) under different pla...
Araújo, Emanuel José Gomes de; Pelissari, Allan Libanio; David, Hassan Camil; Scolforo, José Roberto Soares; Netto, Sylvio PéllicoThe objective of this work was to adjust traditional models of hypsometric relations for homogeneous candeia stands, under different initial spacings. Ten models were adjusted for hypsometric relations. The assessment criteria obeyed the highest determination coefficient and the lowest standard error of estimate in percentage. The F test was also evaluated, as well as the significance of the regression coeffici...
Dendrometric relationship in fragments of pine stands in Minas Gerais
Araújo, Emanuel José Gomes de; Pelissari, Allan Libanio; David, Hassan Camil; Miranda, Rodrigo Otávio Veiga de; Péllico Netto, SylvioThe aim of this work was to adjust diameter distribution, hypsometric relation, taper and volume models to characterize the dendrometric relations on remaining fragments of Pinus sp. from stands of the 1970s, in the region where the Reserva de Desenvolvimento Sustentável Veredas do Acari is located, north of the state of Minas Gerais. The identification of the Pinus sp. fragments and its mapping was made. Biome...
