Diving into the genetics of range shifts

Jorge E. Ramos is a marine biologist with a PhD in Natural and Physical Sciences from the University of Tasmania. His PhD project focused on examining the life-history characteristics, genetics and population dynamics of the range extending common Sydney octopus (Octopus tetricus).

Here, Jorge describes interesting genetic patterns across the shifting distribution of Octopus tetricus.
