Dear Marmammers,

on behalf of all co-authors, I'd like to announce the publication of the following paper:

Cunha HA, Medeiros BV, Barbosa LA, Cremer MJ, Marigo J, Lailson-Brito J, Azevedo F, Solé-Cava AM (2014)
Population Structure of the EndangeredFranciscanaDolphin (Pontoporia blainvillei): Reassessing Management Units. PLoS One 9 (1): e85633. doi:10.1371/journal.pone.0085633

Franciscanas are the most endangered dolphins in
the Southwestern Atlantic. Due to their coastal and estuarine habits,
franciscanas suffer from extensive fisheries bycatch, as well as from habitat
loss and degradation. Four Franciscana Management Areas (FMA), proposed based
on biology, demography, morphology and genetic data, were incorporated into
management planning and in the delineation of research efforts. We re-evaluated
that proposal through the analysis of control region sequences from
franciscanas throughout their distribution range (N = 162), including novel
sequences from the northern limit of the species and two other previouslyunsampledlocalities in Brazil. A deep evolutionary break was observed between franciscanas
from the northern and southern portions of the species distribution, indicating
that they must be managed as two Evolutionarily Significant Units (ESU). Furthermore, additional FMAs should be recognised
to accommodate the genetic differentiation found in each ESU. These results
have immediate consequences for the conservation and management of this
endangered species.
