Resumo: The objective of this work was to analyze the spatial distribution and the behavior of species richness and diversity in a shrub savanna fragment, in 2003 and 2014, using ordinary kriging, in the state of Minas Gerais, Brazil. In both evaluation years, the measurements were performed in a fragment with 236.85 hectares, in which individual trees were measured and identified across 40 plots (1,000 m2 ). Species richness was determined by the total number of species in each plot, and diversity by the Shannon diversity index. For the variogram study, spatial models were fitted and selected. Then, ordinary kriging was applied and the spatial distribution of the assessed variables was described. A strong spatial dependence was observed between species richness and diversity by the Shannon diversity index (<25% spatial dependence degree). Areas of low and high species diversity and richness were found in the shrub savanna fragment. Spatial distribution behavior shows relative stability regarding the number of species and the Shannon diversity index in the evaluated years.

Nos dois anos de monitoramento, as avaliações foram realizadas em um fragmento de 236,85 hectares, em que indivíduos arbóreos foram medidos e identificados em 40 parcelas (1.000 m2 ). A riqueza foi determinada pelo número de espécies em cada parcela, e a diversidade, pelo índice de diversidade de Shannon. Para o estudo variográfico, foram realizados ajuste e seleção de modelos espaciais. Posteriormente, foi aplicada krigagem ordinária e descrita a distribuição espacial das variáveis avaliadas. Observou-se forte dependência espacial entre riqueza e diversidade de espécies pelo índice de diversidade de Shannon (<25% de grau de dependência espacial). Áreas de baixa e alta diversidade e riqueza de espécies foram identificadas no fragmento de campo cerrado. O comportamento da distribuição espacial mostra relativa estabilidade quanto ao número de espécies e ao índice de diversidade de Shannon nos anos avaliados.Embrapa - Secretaria de Pesquisa e Desenvolvimento Pesquisa Agropecuária Brasileira2018-11-17T11:44:49Z2018-11-17T11:44:49Z2016-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfBATISTA, A.
