O presente relatório refere-se a mais uma prospecção realizada dentro do cronograma do Projeto Banco Ativo de Germoplasma (CNPSD/CENARGEN). A mesma foi realizada no km 250 da BR 230 (rodovia Transamazônica), no sentido de Humaitá (AM) - Jacareacanga (PA). Neste relatório são apresentados dados referentes à localização da coleta, solo, vegetação, observações de campo, características da análise da casca e a situação atual do material. |

The ecotone forests in the northern region of Brazilian Amazonia are important areas representing transition zones between forest and non-forest ecosystems. These areas have soils nutrient-poor that poorly drain. Under these environmental conditions, Peltogyne gracilipes (Leguminoseae), an endemic tree species, can form natural monodominant forests. Here, we assessed the arbuscular mycorrhizal fungi (AMF) community in three forest types on the eastern side of Maraca Island and the relationship of these microorganisms with the monodominance of P. gracilipes. In this study, soil samples were collected in two seasons (dry and rainy). The samples were collected in 9 plots, in rich areas, poor areas and areas without P. gracilipes. Soil samples were evaluated for chemical and particle size analysis, spore density and morphology, and identification of AMF. AMF species were identified using two approaches: spores collected in the field and trap cultures. Eighteen and 13 AMF species were identified in the dry and rainy seasons, respectively, for spores extracted from the field. Six total species were detected exclusively in trap cultures in the dry season. AMF communities were co-dominated by members of the Gigasporaceae, Acaulosporaceae and Glomeraceae families. Redundancy analyses indicated that several soil attributes, such as pH, Fe, Mg, and sand content associated with the AMF species richness in both seasons. We conclude that the ecotone forests in the eastern region of Maraca Island are home to important richness and diversity of AMF species and that various soil factors influence the composition of the AMF community in this ecosystem.
