520 |a There is considerable interest in documenting the biodiversity of plants together with the associated microorganisms. We investigated the species composition and colonisation patterns of arbuscular mycorrhizal fungi [AMF] in five vegetation types in El Palmar National Park, Entre Rios, Argentina. The plant communities consisted of: gallery forest, grassland, marsh, palm forest and scrubland. The roots of 103 plant species of 42 families were examined for AMF colonisation. Ninety-three plant species were found to be colonized. Arum-type mycorrhizal colonisation occurred in 74 species, Paris-type in three species, three species had a mix of both Paris- and Arum-type. It was not possible to determine the colonisation type for 13 plant species. A total of 46 taxa of AMF, including the genera Glomus [15 taxa], Acaulospora [14 taxa], Scutellospora [8 taxa], Gigaspora [5 taxa], Archaeospora [1 taxon], Entrophospora [1 taxon], Pacispora [1 taxon] and Paraglomus [1 taxon], were identified. A higher diversity was observed in the grassland and palm forest, mainly due to a high proportion of Acaulosporaceae and Gigasporaceae. El Palmar National Park contains a well-established, highly diverse, native community of AMF. Consequently, the park may act as a place for in situ conservation of Glomer-omycota.
