Abstract
The objective of this study was to determine the structure, diversity, composition and drivers of AMF communities in succession areas of Atlantic Forest. Soil and root samples were collected in three natural ecosystems (mature rainforests, early and late secondary forests) with three areas on each ecosystem. In total, 38 AMF taxa were identified in field samples and three more in trap cultures with a greater richness of Acaulospora and Glomus . Based on a richness estimator, 70% of the AMF species were identified. Highest rates of root colonization and number of glomerospores were recorded in the early secondary forest. AMF species diversity differed between early and late forests. The main drivers of AMF distribution were coarse and fine sand, silt, Al, P, Na, pH and base saturation. The greatest number of exclusive species was recorded in the mature rainforests. The distribution of AMF communities was influenced by different successional stages and some soil attributes.
期刊介绍:
Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
