Resumo: | The purpose of this work was to evaluate composition and aerial biomass dynamics after burning of a grassy-woody savanna in the Pantanal wetlands, Brazil. During 11 months, data on species frequency, aerial biomass and soil cover were collected in an area with burning (WB) and another free of burning (FB), both not grazed. Burning reduced the frequency of the most predominant grasses and increased the number of dicotyledons and cyperaceae species. The production of total aerial biomass was lower in the WB area, despite an increase tendency that was similar in both areas. Litter production was strongly affected by burnings. After 11 months its production was approximately 25% of the production exhibited by the FB area. Soil cover was also lower in the WB and only after four months it was similar to the FB area. |

Foram coletados dados mensais de freqüência de espécies, biomassa aérea e cobertura do solo durante 11 meses em uma área com queima (CQ) e outra sem queima (SQ), ambas sem pastejo. A queima reduziu a freqüência das gramíneas predominantes e condicionou aumento no número de espécies dicotiledôneas e ciperáceas. A produção de biomassa aérea total foi inferior na área com queima, embora a tendência de incremento tenha sido semelhante nas duas áreas. A produção de biomassa morta foi muito afetada pela queima, cuja produção, 11 meses após, representou aproximadamente 25% da obtida na área sem queima. A cobertura do solo foi inferior na área com queima e somente no quarto mês assemelhou-se à área sem queima.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCrispim, Sandra Mara AraújoRodrigues, Cristina Aparecida G.Junior, Waldomiro BarioniCardoso, Evaldo Luis2000-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6026Pesquisa Agropecuaria Brasileira; v.35, n.11, nov. 2000; 2209-2316Pesquisa Agropecuária Brasileira; v.35, n.11, nov. 2000; 2209-23161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6026/3130info:eu-repo/semantics/openAccess2014-08-20T18:38:39Zoai:ojs.seer.sct.embrapa.br:article/6026Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-20T18:38:39Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
