Franciscanas are small coastal cetaceans threatened by human activities, such as by-catch in driftnet fisheries. During the last two decades, research and conservation actions for this species have been delineated based on management units named Franciscana Management Areas (FMA). Recently, genetic data provided preliminary evidence that FMAII comprises two population units. The present study presents new evidence in favour of subdivision of FMAII from genetic, organochlorine compounds and stable isotopes data.
