The goal of this working group is to bring researchers in the fields of population genomics and spatial ecology together to understand how individual dispersal patterns are reflected in genomic population structure. To bridge the gap between population connectivity estimates from the perspectives of population genomics and spatial ecology we must reconcile different definitions of connectivity and the influence of different data types on common connectivity estimations. Identifying a common framework for unifying these branches of population research will allow for increased syntheses of disparate data types and ultimately an increased understanding of population dynamics and the distribution of genetic diversity across the sea. *This project is funded by NSF's RCN for Evolution in Changing Seas.*
