Resumo: Logged forests are more prone to fire, shifts in species composition, and losses in biodiversity. In this work changes in the horizontal structure and species composition of a managed forest in the Tapajós National Forest, Eastern Amazon, Brazil, along 31 years (1981-2012) was evaluated. The disturbances included logging (1982), thinning of non-commercial species (1993/1994), and fire (1997). Data were obtained in 36 0.25-ha permanent plots split in 12 plots per each one of three harvesting treatments. In 1997, 16 plots were reached by an accidental superficial fire. The changes in species composition and diversity between the last measurement after logging and before fire (1995) and the last measurement (2012) were compared. PERMANOVA, considering the relationship between the NMDS axes and the treatment variable (logging / control + unburnt / burnt) differed in species composition, among treatments before fire (1995) and 15 years after fire (2012). The post-hoc test for PERMANOVA showed great similarity among logged forests before and after fire. The forest pre-disturbance conditions were important drivers in forest recovery, since logged forests under heavy thinning presented more losses in basal area and alterations in species composition. Therefore, stronger and more frequent disturbances can compromise the forest resilience.

Neste estudo foram avaliadas as mudanças na estrutura horizontal e a composição de espécies, ao longo de 31 anos (de 1981 a 2012), de uma floresta manejada na Floresta Nacional do Tapajós, Amazônia Oriental, Brasil. Os distúrbios incluíram a exploração madeireira (1982), o desbaste de espécies não comerciais (1993/1994) e a ocorrência de fogo (1997). Os dados foram obtidos em 36 parcelas permanentes de 0,25ha, com 12 parcelas para cada um dos três tratamentos: corte seletivo + desbaste leve de espécies não comerciais, corte seletivo + desbaste intenso de espécies não comerciais e área controle, sendo acrescida aos tratamentos a ocorrência ou não de um incêndio florestal. A PERMANOVA, considerando a relação entre os eixos NMDS e a variável de tratamento (exploração/controle + ocorrência de fogo/sem fogo), indicou diferença na composição de espécies, entre os tratamentos de antes do fogo (1995) e 15 anos após o fogo (2012). Em nenhum dos tratamentos houve perda de diversidade, mas os resultados mostraram que as florestas exploradas com histórico de desbaste pesado apresentaram maiores perdas na área basal e alterações na composição das espécies, com aumento na densidade de indivíduos de espécies pioneiras, principalmente entre as menores árvores. Los bosques sometidos a tala selectiva de madera son más propensos a incendios, cambios en la composición de especies y pérdidas de biodiversidad. En este estudio, se evaluaron los cambios en la estructura horizontal y la composición de especies de un bosque manejado en el Bosque Nacional Tapajós, Amazonía Oriental, Brasil, durante 31 años (1981 a 2012). Las perturbaciones incluyeron tala (1982), raleo de especies no comerciales (1993/1994) y incendio (1997). Los datos se obtuvieron en 36 parcelas permanentes de 0,25ha, con 12 parcelas para cada uno de los tres tratamientos: tala selectiva + aclareo ligero de especies no comerciales, tala selectiva + aclareo intenso de especies no comerciales y área de control, agregándose a la tratamientos la ocurrencia o no de un incendio forestal. PERMANOVA, considerando la relación entre los ejes NMDS y la variable tratamiento (explotación/control + ocurrencia de fuego/no fuego), indicó diferencia en la composición de especies, entre los tratamientos antes del incendio (1995) y 15 años después del incendio (2012). En ninguno de los tratamientos hubo pérdida de diversidad, pero los resultados mostraron que los bosques explotados con antecedentes de fuerte raleo presentaron mayores pérdidas en área basal y cambios en la composición de especies, con un aumento en la densidad de individuos de especies pioneras, especialmente entre los árboles más pequeños. Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio)2022-05-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistaeletronica.icmbio.gov.br/BioBR/article/view/197210.37002/biobrasil.v12i2.1972Biodiversidade Brasileira - BioBrasil; Vol. 12 No. 2 (2022): Fluxo ContínuoBiodiversidade Brasileira - BioBrasil; Vol. 12 Núm. 2 (2022): Fluxo ContínuoBiodiversidade Brasileira - BioBrasil; v. 12 n. 2 (2022): Fluxo Contínuo2236-2886reponame:Biodiversidade Brasileirainstname:Instituto Chico Mendes de Conservação da Biodiversidade (ICMBIO)instacron:ICMBIOenghttps://revistaeletronica.icmbio.gov.br/BioBR/article/view/1972/1391Copyright (c) 2022 Biodiversidade Brasileira - BioBrasilinfo:eu-repo/semantics/openAccessCarvalho de Andrade, Darlison FernandesRoberto Ruschel, AdemirSchwartz, Gustavo de Souza Oliveira , Alan Filipe Freitas dos Santos, MisaelLima da Costa, Daniele Pereira de Carvalho , João Olegário Vasconcellos Gama , João Ricardo 2022-05-06T13:21:24Zoai:ojs.icmbio.gov.br:article/1972Revistahttps://revistaeletronica.icmbio.gov.br/BioBRPUBhttps://revistaeletronica.icmbio.gov.br/BioBR/oaifernanda.oliveto@icmbio.gov.br || katia.ribeiro@icmbio.gov.br2236-28862236-2886opendoar:2022-05-06T13:21:24Biodiversidade Brasileira - Instituto Chico Mendes de Conservação da Biodiversidade (ICMBIO)false
