Riqueza de espécies, estrutura e composição florística de uma floresta secundária de 40 anos no leste da Amazônia

Abstract: A perda de florestas naturais devido a pressões antrópicas levou as florestas secundárias a ocupar uma grande proporção de áreas no leste da Amazônia. Com o objetivo de conhecer as características de uma comunidade arbórea e a estrutura populacional das espécies mais representativas, foram investigadas a riqueza de espécies, a estrutura e a composição florística de uma floresta secundária de 40 anos no município de Bragança (01°11'S e 46°40'W), Estado do Pará, Brasil. A amostragem contou com todos os indivíduo… Show more

“…The composition of the families is similar to other studies held on secondary forests in Amazon region (CARIM et al, 2007;RAYOL et al, 2008;RAYOL et al, 2011;ARAÚJO et al, 2012), being Fabaceae, Malvaceae, Myrtaceae, Salicaceae and Arecaceae the most important in the phytocoenosis.…”

“…in other tropical forests (Guariguata et al 1997, Peña-Claros 2003, Capers et al 2005, Carim et al 2007, Chazdon et al 2007, Liebsch et al 2007, Castillo-Campos et al 2008, Norden et al 2009, Lebrija-Trejos et al 2010. The formation of secondary forest groups composed of distinct regeneration ages, as observed in the grouping analysis and ordinations of the arboreal habit, can be justified by the similarities of the soil characteristics within the groups (which is often a consequence of the close proximity of these areas).…”
