Biological Complexity Unit). \nAbstract:  Oceans host communities of plankton composed of a huge number of rare species that\, as estimated in metagenomic studies\, decay as a steep power law of their abundance. We propose that the way chaotic advection of oceanic currents limit protists dispersal is a key  factor of such biodiversity pattern. We introduce a spatially explicit coalescence model able to reconstruct species ancestry and diversity in the presence of currents. Our model predicts a steep power law decay of the species abundance distribution and a steep increase of the number of observed species with sample size. Indeed\, we find a significant correlation of the local finite-size Lyapunov exponents of our chaotic currents and the power law exponents of the species abundance distribution. Metagenomic studies of planktonic protist communities show excellent agreement with our results. \nReferencia: https://advances.sciencemag.org/content/6/29/eaaz9037 \n\n\nFecha: Viernes 9 de Octubre de 2020\nHora: 12 horas.\nLugar: Laboratorio de Física Computacional\, Planta baja del edificio de Física\, Facultad de Ciencias.\nEl seminario será presencial\, hasta completar el aforo reducido del aula.
