Dear all, on behalf of my co-authors, I’d like to announce thatthe following paper is now available online:

Zoological Journal ofthe Linnean Society This is the first perspective on the geneticdifferentiation of rough-toothed dolphins worldwide. Abstract:
Several delphinid species have shown geneticpopulation structure, both between and within ocean basins. We investigatedgenetic differentiation in the rough-toothed dolphin, Steno bredanensis, using mitochondrial control region sequences from several localitiesworldwide (N = 112). Preliminary analyses indicated highlevels of genetic differentiation between the Atlantic and Pacific/IndianOceans, which were further investigated using complete cytochrome b sequences and mitogenomes. Phylogenetic analyses were inconclusive aboutthe existence of cryptic speciation in the genus Steno.Notwithstanding this result, analysis of molecular variance and Φ-statistics analysesrevealed strong population differentiation not only between the Atlantic andPacific, but also within the Atlantic, where three populations were detected:Caribbean, southeastern Brazil, and southern Brazil. We propose that thesepopulations be considered management units for conservation purposes. Ourresults provide the first perspective on the worldwide genetic differentiationof S. bredanensis. The pdf can be downloaded at: http://onlinelibrary.wiley.com/doi/10.1111/zoj.12301/abstract.
