Resumo: | The objective of this study was to identify communities of arbuscular mycorrhizal fungi (AMF) in soils under pasture, silvopasture, and Cerrado forest ecosystems, and evaluate the effects of land use system, soil texture, and seasonality on the dynamics of AMF communities, in Alta Floresta D'Oeste, Rondônia, Brazil. Samples of the soil 0-20 cm layer were randomly collected in each ecosystem in July, 2010 (dry season) and January, 2011 (rainy season). Spores were extracted, counted, and identified. The spore density and density of each species of AMF were estimated. The frequency of occurrence, Shannon diversity index, and Simpson diversity index were calculated for each species. Multivariate clustering analysis was carried out, considering the number of AMF of each species. The results showed a trend of higher number of spores in the Cerrado forest ecosystem, regardless of the soil texture or season, when compared to pasture and silvopasture areas. The Glomus macrocarpum species presented 100% frequency of occurrence in the rainy season in both soil textures. The effects of texture and seasonality on the composition and diversity of AMF communities was more expressive in the Cerrado forest ecosystem. The climate, soil texture, and land use and management affected the composition and diversity of AMF species. |

As amostras de terra foram coletadas aleatoriamente na profundidade de 0 a 20 cm, em cada um dos ecossistemas em Julho/2010 (período seco) e Janeiro/2011 (período chuvoso). Após extraídos, os esporos foram contados e identificados. Estimou-se a densidade dos esporos e a densidade de cada espécie de FMA. Calcularam-se a frequência de ocorrência de cada espécie, o índice de diversidade de Shannon e o índice de diversidade de Simpson. Realizou-se uma análise multivariada de agrupamento baseado no número de indivíduos das espécies dos FMAs. Houve tendência de um maior número de esporos no ecossistema de mata de Cerrado independente da textura do solo ou da estação do ano, quando comparado as áreas de pastagem e silvipastagem. A espécie de Glomus macrocarpum apresentou 100% de frequência de ocorrência na estação chuvosa em ambas as texturas do solo. A influência da textura e da sazonalidade na composição e diversidade da comunidade dos FMAs foi mais expressiva no ecossistema de mata de Cerrado. O clima, a textura do solo, o manejo e o sistema de uso do solo afetam a composição e diversidade de espécies de FMAs.
