Programa Synthesys

Conferencia: 'Impact of wildfire frequency on the ectomycorrhizal fungal communities of a Mediterranean forest'.

Erika Buscardo, visitante del Programa Synthesys en el Real Jardín Botánico, CSIC, ofrecerá el próximo jueves, 18 de marzo, a las 13:00 horas, en la Sala de Seminarios (frente Pabellón Villanueva), este seminario científico, que se realizará en idioma inglés.

Ectomycorrhizal fungi play an important role in secondary succession processes facilitating regeneration following disturbance events. The effects of wildfire return interval on ECM and in particular on the resistant propagules communities (RPC) are poorly known. For a better understanding of the influence of fire frequency on the ECM communities of a Mediterranean open pine forest we collected soil samples in areas with different fire return intervals and used to test ectomycorrhiza development in two hosts, Pinus pinaster and Quercus suber. The RPC were characterized using PCR-sequencing. Short fire return interval promoted species like Rhizopogon roseolus, and influenced negatively other species like R. luteolus. Inocybe jacobi was positively affected by long fire return interval, but decreased significantly with high fire return interval. The number of ECM species colonizing Q. suber decreased significantly with fire frequency. High frequency fires have different effects than moderate frequency fires on the structure, composition, and diversity of ECM communities, and induce alterations on the ECM communities that could compromise the resilience of the ecosystem.
