Hola a
todas/os:
El VIERNES 1 de
FEBRERO, a las 12h hay un seminarion de investigación en el salón de actos del Museo de Ciencias Naturales (C/José Gutiérrez Abascal 2, 28006-Madrid)
Título: "SECASOL
project: direct and indirect effects of climatic variability on soil microbial
communities and soil C fluxes"
Impartido por: Dr. Jorge Curiel Yuste, Ramón y Cajal Fellow, Museo Nacional de Ciencias Naturales (MNCN-CSIC)
Resumen/Abstract:The aim of our talk
will be to show an overview of the results obtained within the framework of
SECASOL project. The central hypotheses of this project was that both direct
effects (increasing summer droughts) and indirect effects (climate-change
driven changes in forest structure and composition) of climate change in the
Mediterranean basin would strongly affect microbial community ecology and
functioning, and consequently affecting C cycles in these ecosystems. More in
detail, activities within this project were: (1) To investigate possible
effects of climate -change driven secondary succession on soil bacterial/fungal
taxonomic composition as well as soil C dynamics in ecotonal forest. (2) To
investigate possible effects of long-term droughts (10 years) on both structure and functioning
(SOM decomposition) of soil microbial communities (3) To investigate the
effects of secondary succession and drought on soil respiration and its
different biological soil compartments (autotrophic, symbiotic and
heterotrophic). We applied
a very interdisciplinary approach for these purposes, combining
state-of-the-art molecular methodologies (DNA pyrosequencing), 13C
solid-state Nuclear Magnetic Resonance (CP-MAS 13C NMR) to
investigate changes in SOM composition, different techniques to study soil
respiration (soda lime, IRGA and solid-state open path sensors) and methods to
partition flux in its main biological compartments. Besides the observed high
functional redundancy and resilience of soil microbial communities, our results
points to mechanisms of plant-soil interactions as main controllers of soil C
dynamics.
