Abstract:
Abstract: For the first time in tropical mountain rain forest, arbuscular mycorrhizal fungal<br/> richness and community composition was investigated from planted seedlings of Cedrela<br/> montana, Heliocarpus americanus, Juglans neotropica and Tabebuia chrysantha in reforestation<br/> plots on degraded pastures. A segment of fungal 18S rDNA was sequenced from the mycorrhizas.<br/> Sequences were compared with those obtained from mycorrhizas of adult trees of 30<br/> species in the neighboring, pristine tropical mountain rain forest. In total, 193 glomeromycotan<br/> sequences were analyzed, 130 of them previously unpublished. Members of Glomeraceae,<br/> Acaulosporaceae, Gigasporaceae and Archaeosporales were found in both habitats, with Glomus<br/> Group A sequences being by far the most diverse and abundant. Glomus Group A sequence type<br/> richness did not appear to differ between the habitats; a large number was observed in both.<br/> Glomus Group A sequence type composition, however, was found distinctly different. Seedlings<br/> were rarely colonized by fungi of the pristine forest but trapped a number of fungi known from<br/> other areas, which were rarely found in the pristine forest.
