Resumo: | Euterpe precatoria Mart., is used in the cosmetic and food industry and has been increasingly exploited in the Amazonian environment. The objective of this work is to analyze the spatial-temporal dynamics of the landscape and the effect of fragmentation on the structure and pattern of spatial distribution of Euterpe precatoria, using a forest fragment in the municipality of Alta Floresta, MT state. Orbital images of Landsat-2/MSS satellite from 1975, Landsat-3/MSS from 1979, Landsat-5/TM from 1985, 1990, 1995, 2000, 2005 and 2010 and from Landsat-8/OLI from 2017 were used. From the data generated by means of remote sensing, the Anthropic Transformation Index –ITA and Linear Regression were calculated. Two plots of 200 m x 25 m were drawn in the edge-inland direction. The horizontal and vertical structure of the species was characterized by means of the analyzes: number of individuals, density, basal area, diameter distribution and spatial distribution. The spatial distribution pattern was estimated by the Morisita index, with a significance level of 5%. The first anthropic activities around the study fragment began in 1984 with the opening of the MT-325 highway. The intensification of land use contributed to the reduction of vegetation, which most critical period occurred between 1990 and 2000. We sampled 102 individuals in plot A and 218 in plot B. The density was higher in plot B. The two plots had a larger number of individuals distributed in the first diametric class. The analyzed population presented two spatial distribution patterns, random pattern in plot A and aggregate pattern in the B. Euterpe precatoria plot is balanced on the process of succession and the recruitment of individuals, since the values of the 'q' ratio show that there are a large number of individuals in the first height classes and DAP. |

O objetivo deste trabalho é analisar a dinâmica espaço-temporal da paisagem e o efeito da fragmentação na estrutura e no padrão de distribuição espacial da espécie Euterpe precatoria, tendo como modelo um fragmento florestal no município de Alta Floresta-MT. Foram utilizadas imagens orbitais do satélite Landsat-2/MSS de 1975, Landsat-3/MSS de 1979, Landsat-5/TM de 1985, 1990, 1995, 2000, 2005 e 2010 e do Landsat-8/OLI de 2017. A partir dos dados gerados por meio de sensoriamento remoto foi calculado o Índice de Transformação Antrópica – ITA e Regressão Linear. Foram traçadas duas parcelas de 200 m x 25 m, no sentido borda-interior. A estrutura horizontal e vertical da espécie foi caracterizada por meio das análises: número de indivíduos, densidade, área basal, distribuição diamétrica e distribuição espacial. O padrão de distribuição espacial foi estimado pelo índice de Morisita, com um nível de significância de 5%. As primeiras atividades antrópicas no entorno do fragmento de estudo iniciaram-se a partir de 1984 com a abertura da rodovia MT-325. A intensificação do uso da terra contribuiu para a redução da vegetação, cujo período mais crítico ocorreu entre 1990 a 2000. Foram amostrados 102 indivíduos na parcela A e 218 na parcela B. A densidade foi maior na parcela B. As duas parcelas apresentaram maior número de indivíduos distribuídos na primeira classe diamétrica. A população analisada apresentou dois padrões de distribuição espacial, padrão aleatório na parcela A e padrão agregado na parcela B. Euterpe precatoria encontra-se balanceado quanto ao processo de sucessão e recrutamento dos indivíduos, pois os valores da razão ‘q’ mostram que há um grande número de indivíduos nas primeiras classes de altura e DAP.Universidade Federal de Santa Maria2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3173710.5902/1980509831737Ciência Florestal; Vol. 29 No. 3 (2019); 1398-1414Ciência Florestal; v. 29 n. 3 (2019); 1398-14141980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31737/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessCochev, Jakeline SantosRossi, Ana Aparecida BandiniNeves, Sandra Mara Alves da SilvaZortéa, Kelli Évelin MullerRodrigues, Alex de Souza2019-10-01T13:06:32Zoai:ojs.pkp.sfu.ca:article/31737Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-10-01T13:06:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |

The objective of this work is to analyze the spatial-temporal dynamics of the landscape and the effect of fragmentation on the structure and pattern of spatial distribution of Euterpe precatoria, using a forest fragment in the municipality of Alta Floresta, MT state. Orbital images of Landsat-2/MSS satellite from 1975, Landsat-3/MSS from 1979, Landsat-5/TM from 1985, 1990, 1995, 2000, 2005 and 2010 and from Landsat-8/OLI from 2017 were used. From the data generated by means of remote sensing, the Anthropic Transformation Index –ITA and Linear Regression were calculated. Two plots of 200 m x 25 m were drawn in the edge-inland direction. The horizontal and vertical structure of the species was characterized by means of the analyzes: number of individuals, density, basal area, diameter distribution and spatial distribution. The spatial distribution pattern was estimated by the Morisita index, with a significance level of 5%. The first anthropic activities around the study fragment began in 1984 with the opening of the MT-325 highway. The intensification of land use contributed to the reduction of vegetation, which most critical period occurred between 1990 and 2000. We sampled 102 individuals in plot A and 218 in plot B. The density was higher in plot B. The two plots had a larger number of individuals distributed in the first diametric class. The analyzed population presented two spatial distribution patterns, random pattern in plot A and aggregate pattern in the B. Euterpe precatoria plot is balanced on the process of succession and the recruitment of individuals, since the values of the 'q' ratio show that there are a large number of individuals in the first height classes and DAP. |
