Resumen
Este estudio investigó la sucesión temporal de las comunidades de hongos micorrícicos
arbusculares (HMA) en un sistema de islas de diferentes edades en un ambiente costero. Todavía
existe una brecha de conocimiento respecto a las fuerzas que impulsan la sucesión primaria de los
HMA. Planteamos la hipótesis de que las etapas sucesionales tempranas son gobernadas por
procesos estocásticos, mientras que más tarde sus comunidades estarán más influenciadas por
factores deterministas como respuesta al entorno abiótico. Nuestra tarea principal fue analizar un
conjunto de datos moleculares sobre la composición de la comunidad de HMA, analizando los
cambios en la diversidad alfa, beta y filogenética. La diversidad beta no mostró un aumento
significativo a lo largo del tiempo. Sin embargo, la diversidad alfa aumentó indicando una mayor
diversidad de especies de HMA a medida que avanzaba la sucesión. Enfatizamos la importancia de
incorporar tanto factores estocásticos como deterministas para entender la sucesión de los HMA.
This study investigated the temporal succession of arbuscular mycorrhizal fungal (AMF) communities in a system of islands of varying ages in the coast of northern Europe. There is still a gap of knowledge concerning the forces that drive the primary succession of AMF. We hypothesized that early successionalstages were primarily governed by stochastic processes, while later stages will be more influenced by deterministic factors as a response to the abiotic environment. Our main was to analyze a molecular dataset of AMF community composition. We analyzed the change of alpha, beta and phylogenetic diversity of the AMF communities. Contrary to our expectations, beta diversity did not show a significant increase over time. However, alpha diversity did increase, indicating a higher diversity of AMF species as succession advance. Overall, this study emphasizes the importance of incorporating both stochastic and deterministic factors when examining the formation of AMF communities during succession.
