More Information
  • The symbiotic association between AMF and plants in coastal areas is a major strategy for the survival of native vegetation, due to the ability of external hyphae of fungi to absorb the scarce nutrients in substrates and to further the aggregation of soil particles promoting its stability. Despite its importance to the maintenance of coastal ecosystems, little is known about the dynamics of the AMF communities in tropical areas. The aim of this study was to evaluate the occurrence and diversity of AMF in maritime dunes from the Parque Ecológico Dunas de Genipabu, in Rio Grande do Norte (RN), Brazil. From August / 2010 to February / 2012, on four occasions in the rainy and dry seasons, rhizosphere soil samples from 48 plants were collected and 46 species of AMF were found, distributed among 10 families: Glomeraceae (12), Acaulosporaceae (7) Dentiscutataceae (7), Diversisporaceae (2), Gigasporaceae (5), Scutellosporaceae (4), Ambisporaceae (3), Racocetraceae (3), Intraornatosporaceae (2) and Sacculosporaceae (1). A higher richness and diversity were associated with dry season. The data obtained show that coastal areas are AMF diversity hotspots, with a high number of species associated with native vegetation.

Abstract: The symbiotic association between AMF and plants in coastal areas is a major strategy for the survival of native vegetation, due to the ability of external hyphae of fungi to absorb the scarce nutrients in substrates and to further the aggregation of soil particles promoting its stability. Despite its importance to the maintenance of coastal ecosystems, little is known about the dynamics of the AMF communities in tropical areas. The aim of this study was to evaluate the occurrence and diversity of AMF in maritime dunes from the Parque Ecológico Dunas de Genipabu, in Rio Grande do Norte (RN), Brazil. From August / 2010 to February / 2012, on four occasions in the rainy and dry seasons, rhizosphere soil samples from 48 plants were collected and 46 species of AMF were found, distributed among 10 families: Glomeraceae (12), Acaulosporaceae (7) Dentiscutataceae (7), Diversisporaceae (2), Gigasporaceae (5), Scutellosporaceae (4), Ambisporaceae (3), Racocetraceae (3), Intraornatosporaceae (2) and Sacculosporaceae (1). A higher richness and diversity were associated with dry season. The data obtained show that coastal areas are AMF diversity hotspots, with a high number of species associated with native vegetation.
