Padrão espacial de espécies arbóreas em fragmento de floresta estacional semidecidual

Abstract: RESUMO:Conhecer 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 cm foram coletados em fragmento de Floresta Estacional Semidecidual. As coordenadas das espécie… Show more

“…Among these species, Vantanea parviflora was the only one with variations in the spatial pattern at different distance scales, behavior that was also observed by Araújo et al (2014) in individuals from Callisthene major Mart. These variations may be related to the size of the individual, since the younger individuals tend to appear closer to each other, forming aggregates.…”

“…These variations may be related to the size of the individual, since the younger individuals tend to appear closer to each other, forming aggregates. According to Araújo et al (2014), there is an increasing competition as these individuals grow, and few reach the larger diameter being more distant from each other, causing random distribution.…”

“…As variações de padrão na escala de distância são geralmente relacionadas ao porte arbóreo das árvores, pois árvores mais jovens tendem a ocorrer mais próximas umas das outras, formando agregados. À medida que elas crescem ocorre aumento da competição e poucas alcançam os maiores diâmetros, ficando mais distantes umas das outras, o que leva a distribuição aleatória (Araújo et al 2014 A maior ocorrência de árvores com fuste do tipo 1e 2, aliado ao estoque de colheita simulado para o manejo madeireiro da espécie e a análise de sua distribuição diamétrica, demonstram o potencial da área para um possível manejo madeireiro. De acordo com Silva (2010), a forma do fuste sem achatamento e curvatura são determinantes para se obter boa qualidade e rendimento satisfatório no processo de madeira serrada.…”

“…The spatial pattern with the 100% inventory data was defined by the Ripley function K(s). The calculation of K(s) was performed as a function of a circle with a radius of 5 m centered in each tree, in which the number of events present in the area of that circle was counted (Araújo et al, 2014). By varying the radius at a maximum distance of 500 m, the spatial pattern of the species was detected at different distance scales.…”
