The role of oceanographic processes in mediating passive marine dispersal events is poorly understood. We conducted transect surveys across the subtropical front (STF), a major oceanographic boundary, to test the hypothesis that this physical feature constrains the rafting of detached macroalgae. Specifically, we used genetic analysis to assess the geographic origins of floating bull-kelp Durvillaea antarctica specimens in southern New Zealand. Nearly half of the floating specimens sampled...[Show more]
