Resumo: The objective of this research was to evaluate the dynamics of Protium pallidum Cuatrec. Regenerants, in clearings resulting from selective logging, nine clearings were used in this study, ranging in size from 231m2 to 748m2. Each clearing had its center determined and from the edge four strips of 10m x 50m were marked in the North, South, East and West directions. For the evaluation of natural regeneration, three plots of 2m x 2m were implanted in each strip, at distances of 0, 20 and 40m respectively. the mathematical models called Natural Regeneration Rate (TR%), Ingresso (I%) and Mortality (M%) were used. Three-way analysis of variance was performed. There was no significant difference in the TR% values as a function of distances, as well as directions and also as a function of years, however this TR% had the highest values recorded for the South direction and in the plot 40m away in the interior of the sub- grove.

Los estudios sobre estos eventos son esenciales para comprender las posibles direcciones de la sucesión forestal y pueden ser indicadores importantes de la sostenibilidad de los bosques tropicales y los sistemas de manejo. Este estudio tuvo como objetivo evaluar la dinámica de individuos de regeneración natural (DAP <5cm) de Protium pallidum Cuatrec., Bajo la influencia de claros, mediante la determinación de las tasas de entrada, mortalidad y regeneración natural, en un tramo de bosque tropical primario. explorado en el Estado de Pará, Brasil. A partir de esta exploración se originaron varios claros, de los cuales nueve se utilizaron en este estudio, que varían en tamaño desde 231m2 a 748m2. Cada claro tenía su centro determinado y desde el borde se marcaron cuatro franjas de 10 mx 50 m en las direcciones norte, sur, este y oeste. Para la evaluación de la regeneración natural, se implantaron tres parcelas de 2m x 2m en cada franja, a distancias de 0, 20 y 40 m respectivamente. Posteriormente se utilizaron modelos matemáticos denominados Tasa de Regeneración Natural (TR%), Ingresso (I%) y Mortalidad (M%). Los datos fueron analizados en el programa SYSTAT 10, mediante el análisis de varianza de tres factores (direcciones, distancias y el período de tres años). No hubo diferencia significativa en los valores de TR% tanto en función de distancias, como de direcciones y también en función de años, sin embargo este TR% tuvo los valores más altos registrados para la dirección Sur y en la parcela 40 m dentro de la sub-arboleda.O objetivo desta pesquisa foi avaliar a dinâmica de regenerantes de Protium pallidum Cuatrec., em clareiras resultantes da exploração madeireira seletiva, foram utilizadas nove clareiras neste estudo, com tamanho variando entre 231m2 e 748m2. Cada clareira teve seu centro determinado e a partir da borda, foram marcadas quatro faixas de 10m x 50m nas direções Norte, Sul, Leste e Oeste. Para a avaliação da regeneração natural, foram implantadas três parcelas de 2m x 2m em cada faixa, nas distâncias de 0, 20 e 40m respectivamente. utilizou-se os modelos matemáticos denominados Taxa de Regeneração Natural (TR%), Ingresso (I%) e Mortalidade (M%). Foi feita a análise de variância de três fatores. Não houve diferença significativa dos valores de TR% tanto em função das distâncias, quanto das direções e também em função dos anos, porém essa TR% teve os maiores valores registrados para a direção Sul e na parcela a 40m de distância no interior do sub-bosque.Research, Society and Development2021-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1353410.33448/rsd-v10i3.13534Research, Society and Development; Vol. 10 No. 3; e41510313534Research, Society and Development; Vol. 10 Núm. 3; e41510313534Research, Society and Development; v. 10 n. 3; e415103135342525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13534/12131Copyright (c) 2021 Stone César Cavalcante da Costa; Fernando Cristóvam da Silva Jardim; Francimary da Silva Carneiro; Marcio Braga Amorim; Klewton Adriano Oliveira Pinheirohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Stone César Cavalcante da Jardim, Fernando Cristóvam da Silva Carneiro, Francimary da Silva Amorim, Marcio Braga Pinheiro, Klewton Adriano Oliveira 2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/13534Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:51.228101Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
