As neotropical forests are increasingly converted to agriculture (especially pastures), little is known about the impacts on microbial biodiversity. To assess such impacts, spore abundance and diversity of arbuscular mycorrhizal fungi (AMF) (Glomales) in soils from lowland evergreen forests and pastures in Nicaragua and Costa Rica were compared. Species composition, dominance-diversity curves, and Simpson's diversity indices were similar for both forest and pasture soils.
