Dear colleagues,

We are pleased to announce the publication of the following article:

Vermeulen, E., Balbiano, A., Beleguer, F., Colombil, D., Failla, M.,
Intrieri, E., Bräger, S. 2016. *Site-fidelity and movement patterns of
bottlenose dolphins in central Argentina: essential information for
effective conservation. *Aquatic Conservation. DOI: 10.1002/aqc.2618

1. The effectiveness of conservation measures such as marine protected
areas (MPAs) for the conservation of cetaceans is determined by how well
their home range or critical habitat is covered. The present study seeks to
provide information on the site-fidelity and movement patterns of
individual bottlenose dolphins (*Tursiops truncatus*) in central Argentina.
2. Between 2007 and 2013, photo-identification data of bottlenose dolphins
were collected in four study sites some 90–200km apart from each other
along the central Argentinean coast.
3. Results show long-term site-fidelity (over 5 years) in one of the study
areas. Re-sighting rates further suggest the existence of different
sub-populations of bottlenose dolphins, but also confirm some connectivity
(with movements over 200–290 km) and thus potential for gene flow within
the region.
4. Considering the population declines of bottlenose dolphins in Argentina,
information on site-fidelity and movement patterns will be of value to
improve the effectiveness of existing MPAs for the conservation of the
species as well as prioritizing areas for increased research.
