| The diversity of arbuscular mycorrhizal (AM) fungi in six Capsicum annuum or Lycopersicum escuíentum L. horticultural production systems of small farmers, and of two wheat agrosystems was comparatively investigated in Southern Chile (La Araucania). Soils in this region are mostly originated by volcanic ashes which are characterized by high organic matter content and high P-fixing capacity. Arbuscular mycorrhizal fungal symbioses are playing a key role for P uptake by horticultural crops grown there. The objective of this study was to determine AM fungal communities in cropping systems and to identify soil factors affecting their frequency and diversity. Of the totally 32 AM fungal species identified, 5 to 21 AM fungi species were found in horticultural... |

| Three forest reserves, with highly degraded areas, are open to visitors in Maringá, Paraná, Brazil. Impact caused by tree cutting, heavy traffic and visitors on the establishment of arbuscular mycorrhizal fungi (AMF) was evaluated in two areas with different degradation stages of the Dr. Luis Teixeira Mendes Forest Garden, a remnant of semideciduous forest. Soil samples were removed from three locations within each area; spores were isolated from the soil by wet sieving and sucrose centrifugation and mounted on permanent slides. Spores were counted and identified taxonomically under a microscope. Diversity, dominance, equitability and similarity indexes were calculated from abundance data. The degraded area had the highest number of spores and featured... |

| As micorrizas são consideradas importante componente na recuperação e restabelecimento da vegetação em áreas frágeis ou degradadas, bem como na manutenção da biodiversidade de plantas e das funções dos ecossistemas. O conhecimento da diversidade e dinâmica dos fungos micorrízicos arbusculares (FMA) em áreas impactadas pela ação humana é importante para seu manejo e como indicador de sua qualidade. O Parque Cinqüentenário, localizado no município de Maringá, PR, pertence à formação original do conjunto Mata Atlântica, do domínio da floresta Estacional semi-decidual, é um dos poucos remanescentes florestais existentes na cidade de Maringá, PR, e encontra-se em estádio acelerado de degradação. O objetivo deste trabalho foi avaliar a diversidade de FMA nativos... |
