Physical oceanography meets genetics: tools for marine biodiversity conservation

I present results from an ongoing collaboration between the oceanscape genetics team and the division’s physical oceanographers. We are combining modelling tools from physical oceanography with observational and analytical tools from molecular ecology to investigate how the hydrodynamics of Australian waters determine the spatial and temporal connectivity of marine populations and ecosystems. Three dimensional particle dispersal modelling based on the BlueLink Reanalysis product is used to generate predictions of connectivity as a function of larval dispersal and migration, and molecular genetics is then used to test these predictions by characterising spatial population structure. This structure reflects realised patterns of larval and adult dispersal at multigenerational timescales. We are applying this approach in a comparative study of connectivity in sea urchins in southwest WA, in a study aimed at informing management of WA’s iconic recreational dhufish fishery and in a study of connectivity among southeast Australian Marine Protected Areas using seamount fauna.
