GENERAL ORAL SESSIONS Morning, afternoon and evening sessions (Monday 7th to Thursday 10th) A number of abstracts have been selected for presentation in nine General Oral Sessions (GO) which will take place in parallel to Symposia and Workshops. Due to the large number of applications for oral presentation received these presentations will have 15-min long format. The Organizing Committee decided to allocate some oral presentations to particular sessions, always in agreement with the organizers and presenters, and when the thematic affinities permitted it. General Oral Sessions will take place in: Celestino Mutis building (CITIUS II) Edificio Celestino Mutis (CITIUS II) Reina Mercedes Ave., 41012 Sevilla Conference Classroom (Salón de Grados) Faculty of Biology – Red Building Facultad de Biología – Edifício Rojo Reina Mercedes Ave. 6, 41012 Sevilla Conference Classroom (Salón de Grados), ground floor GO-1 GO-2 GO-3 GO-4 GO-5 GO-6 GO-7 GO-8 GO-9 Cell Biology Taxonomy - Environmental Microbiology (I) Genomics/Molecular Biology – Parasitology (I) Parasitology (II) Evolution/Phylogeny (I) Evolution/Phylogeny (II) Evolution/Phylogeny (III) Environmental Microbiology (II) Ecology - Barcoding GO-1 (Monday 7th, 10.00-11.40 h) Cell Biology Chair: Juan C.
