The integrative approach uses many tools, including field work, molecular biologe (population genetics/genomics), paleoecology and modelisation. The conceptual frame allows the joint study of the various responses in order to acquire a global perspective, from genes to ecosystems.QCBS studentsJulie Morin-RivatPostdoctoral fellow Relevant QCBS research themes
