Efeito Do Fogo Sobre Vegetação E Solo a Partir De Estudo Experimental Em Ambiente De Cerrado

Abstract: <p>Muito se discute sobre o efeito do fogo ao ecossistema, podendo ser positivo ou desprezível para seu desenvolvimento ou ainda degradante do meio. Contudo, o seu efeito e intensidade de alteração no ambiente terá influência de acordo com as características do ecossistema que atinge. Sendo assim, o presente trabalho tem como objetivo compreender e quantificar o efeito do fogo sobre um ambiente de Cerrado mineiro em estado de recuperação, utilizando como parâmetro de análise o tempo de reestabelecimento … Show more

“…Still regarding 2016, larger productions of buds and flowers per panicle in the burned area may have been favored by the greater availability of light and nutrients such as calcium, phosphorus and nitrogen on the soil surface soon after burning (Kellman, 1984;Kauffman et al, 1997) and neutralization of soil acidity by means of ash (Costa and Rodrigues, 2015). The reproductive effort of individuals in the burned area was higher when compared to the control area, even with less loss of buds before developing flowers, 64% before to 74% of the control area.…”

“…However, in recent history the fire frequency has been significantly altered due to the anthropogenic actions, contributing to increasing the degradation of this biome considered one of the great world biodiversity hotspots (Myers et al, 2000;Fiedler et al, 2004). Fires can affect flowering and fruiting (Miranda, 1995;Sanaiotti and Magnusson, 1995;Miola et al, 2010;Palermo and Miranda, 2012;Françoso et al, 2014;Deus et al, 2016;Sato et al, 2018), including pollinators richness and abundance (Giehl et al, 2013;Deus et al, 2016), seed dispersion, recruitment and mortality rates of several species (Miranda and Sato, 2005;Medeiros and Miranda, 2005;Cirne and Miranda, 2008;Bouchartdet et al, 2015) especially in the driest months (Costa and Rodrigues, 2015).…”

“…Uma série de estudos apresenta resultados sobre a influência dos aerossóis no índice de precipitação. Esses estudos relataram correlações positivas ou negativas entre aerossóis, como a Profundidade Ótica de Aerossóis, doravante denominada AOT, e o índice de precipitação, a radiação a saúde humana, e a qualidade do ar com base em produtos de dados observacionais CHENG et al, 2017;COSTA et al, 2015;PALACIO et al, 2014;CAMPONOGARA et al, 2014;CARREA et al, 2013;COELHO et al, 2013;SILVA DIAS et al, 2012;COELHO et al, 2012;FREITAS, 2011;TORRES et al, 2010;VENDRASCO et al, 2009;SENA et al, 2013;SISENANDO et al, 2012SISENANDO et al, , 2011ROSÁRIO et al, 2011;YAMASOE et al, 2006;PROCOPIO, S. et al, 2004;ARTAXO et al, 1998;GOTO et al, 2011;PIRES-NETO et al, 2007;LONGO et al, 2013;PEREIRA et al, 2011;FREITAS et al, 2011FREITAS et al, , 2005. No entanto, é importante notar que as correlações observadas não implicam causalidades e que podem ser atribuídas a fatores externos.…”

“…Cerrado's climate acts directly on the vegetation, the soil, the availability of water, fire's frequency and depth of the water table. Due to the weather to the action of fire, there is constant mention of the physical and chemical effects on soil and vegetation through fires (Nascimento, 2001;Costa and Rodrigues, 2015).…”
