ABSTRACT The effect of arbuscular mycorrhizal fungi on seedling growth across the rain forest-pasture edge has not received much attention. In a tropical rain forest in eastern Mexico, the seedlings of light demanding ( Ficus insipida ), nonsecondary light demanding ( Lonchocarpus cruentus ) and shade tolerant species ( Nectandra ambigens, Coccoloba hondurensis ) were grown and transplanted to a forest edge with three inoculation treatments (AM fungus spores and colonized roots, spores, and no inoculum). For all species, stem height, stem diameter, tota...
