Resumo: The analysis of the oscillations of biomass stocks in tropical forests allows us to describe the behavior of these ecosystems in the face of natural or anthropogenic changes. The objective of this study was to evaluate the inventory and dynamics of biomass in the period (2007-2010) in dense rain forest in two areas of research in the National Forest – Tapajos, eastern Amazonia, called Area 1 and Area 2, 45 km distant from each other. The biomass was estimated using allometric equation and DAP, from 12 permanent plots, with six in each area. The results showed a significant difference in annual average stock biomass between Area 1 (293.19 ± 27.74, 298.21 ± 31.73, 299.60 ± 29.46, 298.11 ± 29.40 Mg. ha-1) and Area 2 (254.35 ± 69.61, 259.10 ± 70.05, 261.00 ± 69.43, 248.92 ± 61.78 Mg.ha-1). Besides that, it was noted annual change in stock biomass measurements at intervals of greater than one year due to fluctuations in mortality, recruitment and growth, besides the basal area and abundance of individuals in each area. The highest concentration of individuals occurred in diametric classes DAP 10 ≤ DAP ≤ 30 cm, however, it was verified that individuals with DAP ≥ 60 cm in lower concentration stored biomass equivalent to diametric classes 10 ≤ DAP ≤ 30 cm. We conclude that fluctuations in mortality, recruitment and growth, and abundance and basal area of these sites affected the stock biomass.

O objetivo deste trabalho foi avaliar o estoque e a dinâmica de biomassa no período (2007-2010) em Floresta Ombrófila Densa de duas áreas de pesquisa na FLONA - Tapajós: Amazônia oriental, denominadas Área 1 e Área 2, distantes aproximadamente 45 km uma da outra. A biomassa foi estimada através de equação alométrica e medidas de DAP, proveniente de 12 parcelas permanentes, sendo 6 em cada área. Os resultados mostraram que houve diferença significativa no estoque médio anual de biomassa entre a Área 1 (293,19 ± 27,74; 298,21 ± 31,73; 299,60 ± 29,46; 298,11 ± 29,40 Mg.ha-1) e a Área 2 (254,35 ± 69,61; 259,10 ± 70,05; 261,00 ± 69,43; 248,92 ± 61,78 Mg.ha-1). Notou-se variação anual no estoque de biomassa em intervalos de medições superiores a um ano, devido às oscilações na taxa de mortalidade, recrutamento e incremento, além da área basal e abundância dos indivíduos em cada área. A maior concentração de indivíduos ocorreu nas classes diamétricas 10 ≤ DAP ≤ 30 cm, porém, verificou-se que os indivíduos com DAP ≥ 60 cm em concentração menor estocam biomassa equivalente à da classe diamétrica 10 ≤ DAP ≤ 30 cm. Concluiu-se que as oscilações na taxa de mortalidade, recrutamento e incremento, além da abundância e área basal nestes locais afetaram os estoques de biomassa.Universidade Federal de Santa Maria2018-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3338810.5902/1980509833388Ciência Florestal; Vol. 28 No. 3 (2018); 1049-1059Ciência Florestal; v. 28 n. 3 (2018); 1049-10591980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33388/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessSantos, Fabio GuerraCamargo, Plinio Barbosa deOliveira Junior, Raimundo Cosme de2018-11-14T10:03:46Zoai:ojs.pkp.sfu.ca:article/33388Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-11-14T10:03:46Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
