Resumo: The size and spatial structures of populations are a synthesis of demographic attributes and indicators of competitive ability, colonization, and survival. In this study, the objective was to analyze the height and spatial pattern of an understory and canopy/emergent tree populations group in two protected fragments of seasonal semideciduous forest, one with a history of selective logging and another without selective logging evidences. Six species with high importance values (IV) from different guilds were selected and height and spatial pattern analysis was realized in both areas. Then, comparison of results was realized in an area with history of selective logging and another without selective logging evidences. Differences in height and spatial pattern were found between the two areas, including species not directly exploited. In Logged Forest the size structure for all species presented a higher coefficient of skewness, showing a greater proportion of young trees. Random distribution was observed for the majority of species in both areas. Some emergent/canopy species had a deficit of individuals in the largest size classes and the majority of understory species showed more individuals in Logged Forest. Selective Logging changed the pattern of populations. Selecting species based on IV together with spatial patterns data contribute to demonstrating the impacts of exploitation. The Logged Forest is surrounded by an agricultural matrix, limiting arrival and dispersion of propagules of shade-tolerant species. Efforts to connect surroundings fragments to Logged Forest will be necessary.

En este estudio, el objetivo fue analizar el tamaño y la estructura espacial de un grupo de poblaciones de árboles de sotobosque y dosel/emergentes en dos fragmentos de bosque semideciduo, uno con historia de tala selectiva y el otro sin evidencia de tala selectiva. Se seleccionaron seis especies con valores altos de importancia (VI) y de diferentes gremios y se realizó el análisis de tamaño y estructura espacial en ambas áreas. comparamos los resultados por área. Se encontraron diferencias de tamaño y estructuras espaciales entre las dos áreas, incluidas las especies no explotadas directamente. En el bosque donde se realizó la tala selectiva, la estructura de tamaño para todas las especies mostró un coeficiente de asimetría más alto, mostrando una mayor proporción de juveniles. El patrón de distribución aleatoria se observó para la mayoría de las especies en ambos fragmentos. Algunas especies de dosel/emergentes tuvieron menor abundancia en las clases de mayor altura. La tala selectiva cambió el patrón de poblaciones. La selección de especies basada en VI junto con los patrones de distribución espacial contribuye a demostrar los impactos de la exploración. El área con antecedentes de tala selectiva lo es rodeada por una matriz agrícola, lo que limita la llegada y propagación de propágulos de especies tolerantes a la sombra. Se hacen necesarios los esfuerzos para la conectividad con otros fragmentos de bosque en los alrededores.O tamanho e a estrutura espacial das populações são uma síntese de atributos demográficos e indicadores de capacidade competitiva, colonização e sobrevivência. Neste estudo, o objetivo foi analisar o tamanho e a estrutura espacial de um grupo de populações arbóreas de sub-bosque e dossel/emergentes em dois fragmentos de Floresta Estacional Semidecidual, um com histórico de corte seletivo de madeira e outro sem evidências de corte seletivo. Seis espécies com altos valores de importância e de guildas diferentes foram selecionadas e a análise de tamanho e estrutura espacial foi realizada em ambas as áreas. Em seguida, comparamos os resultados das espécies na área com histórico de corte seletivo com a área que não sofreu corte seletivo. Diferenças de tamanho e estruturas espaciais foram encontradas entre as duas áreas, incluindo espécies que não exploradas diretamente. Na floresta em que ocorreu o corte seletivo, a estrutura de tamanho para todas as espécies apresentou um maior coeficiente de assimetria, mostrando uma maior proporção de juvenis. O padrão de distribuição aleatória foi observado para a maioria das espécies em ambas as áreas. Algumas espécies do dossel/ emergentes tiveram menor abundância nas maiores classes de altura. O corte seletivo alterou o padrão das populações. Selecionar espécies baseado no VI juntamente com padrões de distribuição espacial contribuem em demonstrar os impactos da exploração. A área com histórico de corte seletivo é circundada por matriz agrícola, limitando a chegada e dispersão de propágulos de espécies tolerantes à sombra. Esforços para conectividade com fragmentos do entorno serão necessários.Research, Society and Development2021-09-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1989710.33448/rsd-v10i11.19897Research, Society and Development; Vol. 10 No. 11; e487101119897Research, Society and Development; Vol. 10 Núm. 11; e487101119897Research, Society and Development; v. 10 n. 11; e4871011198972525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/19897/17754Copyright (c) 2021 Yves Rafael Bovolenta; Diego Resende Rodrigues; Edmilson Bianchini; José Antonio Pimentahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBovolenta, Yves RafaelRodrigues, Diego ResendeBianchini, EdmilsonPimenta, José Antonio2021-10-23T19:01:11Zoai:ojs.pkp.sfu.ca:article/19897Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:41.395132Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
