“…Carneiro et al (2009) also found lower sporulation under native vegetation of Cerrado, for both sandy soil, similar to that of the present study, and clayey soil. A similar pattern was also observed by Sturmer & Siqueira (2011) in the Amazon biome, by Lima et al (2007) in areas of Caatinga and Zandavalli et al (2008) in Araucaria forests in Southern Brazil. According to Lima et al (2007), the negative anthropic interference has different effects in the study on variations in each system; while the increase in degradation level stimulated AMF multiplication in areas of native vegetation, the opposite effect occurred in crop areas.…”

“…According to McGee (1989), the number of viable spores in arid and semi-arid regions is usually relatively low. Lima et al (2007) also observed that the number of viable spores was low, oscillating between 1.5 and 3.7% of the totalnumber of spores, regardless of the land use system. The authors attributed these results to the environmental conditions of the semi-arid region in which the work was conducted.…”

“…However, in the dry period, an increase to 84 and 62% was observed in mycorrhizal colonization in the maize + beans and in the opuntia systems, respectively, in the presence of gliricidia and maniçoba trees. Due to their deep root systems, the gliricidia trees possibly had greater tolerance for water stress, which promoted greater stability and resistance in the production systems, as they may have been able to take up water and nutrients from deeper layers of the soil (MARIN et al, 2007).…”

“…Além disso, os FMAs podem ainda determinar o padrão de sucessão de uma comunidade vegetal (RAMOS ZAPATA; ORELLANA; ALLEW., 2006;STÜRMER;SIQUEIRA, 2010). A degradação dos ecossistemas é resultado de fatores diversos que atuam sobre o solo e sua vegetação, alterando suas propriedades físico-químicas e principalmente biológicas, comprometendo o funcionamento dos sistemas simbióticos, tais como as micorrizas arbusculares (LIMA et al, 2007;SIQUEIRA et al, 2007). A baixa resiliência é uma característica marcante de um ecossistema degradado, pois a sua recuperação pode ser lenta ou até mesmo não ocorrer, o que demanda a intervenção antrópica por meio de práticas de recuperação do solo e consequentemente o monitoramento da sua eficácia (LIMA et al, 2007).…”
