How You Doin': Dolphins Use Whistles to Say Hello

What does a dolphin say when it crosses oceanic paths with other dolphins? Hello, of course, followed by a formal introduction that’s relayed through a high-pitched “signature whistle.” Marine biologists from the University of St. Andrews in Scotland have long been studying dolphin’s cacophonous communication style — including a series of clicks, pulses and whistles — while the animal is in captivity. But until recently, they questioned how the signature whistles were used in the wild.

Now, they have an answer. The researchers used underwater microphones to follow pods of bottlenose dolphins in St. Andrews Bay. After weeding out some of the other sounds the animals make, they were able to determine that dolphins utilize their “signature whistles” when meeting up with other pods of dolphins — much like a catchphrase. Think, “Hey, how’s it going?” but in whistle form.

“It’s not just ‘I’m so-and-so,’ but the other information also in that whistle is, ‘I’m so-and-so, and I’m interested in making contact in a friendly way, I’m not attacking,’” Vincent Janik, one of the study’s researchers. “What I found really rewarding is to be out there and see how they communicate amongst themselves,” Janik said. “These are wild groups that are just doing whatever they’re doing. It’s really the first time that we can pinpoint down two individual groups and how they interact in a vocal domain, which is really cool.”

  • Looking at telemetry data from above and below: some technological and methodological thoughts of an animal movement ecologist

    Telemetry (the remote collection of data via communications systems) allows us to study animals that we would otherwise be unable to observe, in environments we don't have easy access to. The collection of such data is racing ahead of the analytical techniques we have available to understand the data and the systems under study. The type of information we can or should collect both determines, and is determined by, the questions we are able to address regarding the ecology, life-history and behaviour of animals. Challenging systems are often the most interesting, and sometimes the most important to study, but they present us with special practical and analytical challenges. Even though we now have the capacity to collect data in more detail and greater quantities than ever before, we often still have to make do with whatever we can get, or conversely, end up with data in large volumes or with more complexity than we know how to analyse. I will present examples of the data types and study systems I work with, including seals and black eagles, the importance of knowing how data are collected, and some of the methods I use to try to get the most out of these data.

    06-07-2015 at 09-00 - Academic, Conference, Meeting
    THIRD INTERNATIONAL ENVIRONMENTAL 'OMICS SYNTHESIS CONFERENCE

    The IEOS Conference Organising Committee
    University of St Andrews

    The aim of this conference is to bring together researchers and organisations from a range of disciplines with shared interests in the development of new approaches for data handling, generation and analysis in environmental omics. It is our hope is that the resulting interaction and exchange of ideas will lead to novel approaches, new collaborations and the consolidation of a wider integrated environmental ‘omics community.

    <p>ABSTRACT (TALK) and REGISTRATION DEADLINE: 6 June 2015 Science areas include bioinformatics, DNA-barcoding, genomics, metagenomics, metabarcoding, transcriptomics, proteomics, metabolomics, epigenetics, evolutionary and ecological omics, phylogenetics, study of ancient DNA and anthropology, new tools, resources and training--as applied to the study of the natural environment and environmentally relevant organisms and systems. We hope the resulting interactions and exchange of ideas will lead to novel approaches, new collaborations and the consolidation of a wider integrated environmental &lsquo;omics community. Keynote speakers are Professor Elizabeth Thompson from the University of Washington, Professor Mark Blaxter from the University of Edinburgh, and Professor Barbara Meth&eacute;, J Craig Ventor Institute. Invited speakers include Dr Logan Kistler from the University of Warwick, Dr Umer Zeeshan Ijaz from the University of Glasgow, and Dr Nathan Bailey from the University of St Andrews.</p>
