The Sea Mammal Research Unit carries out fundamental, cutting-edge research on marine mammals in many different subject areas. This research is carried out worldwide with a core objective of understanding the causes and consequences of changes in populations. With ever increasing pressure on the world's oceans and it resources, marine mammals are consequently often impacted by man's marine activities. One of our main aims is to therefore determine the nature, magnitude and significance of these expanding interactions.

  • Discrimination of fast click series produced by tagged Risso’s dolphins (Grampus griseus) for echolocation or communication 

    Arranz Alonso, P.; DeRuiter, S. L.; Stimpert, A. K.; Neves, Silvana; Friedlaender, A. S.; Goldbogen, J. A.; Visser, F.; Calambokidis, J.; Southall, B. L.; Tyack, P. L. (2016-07-08) - Journal article
    Early studies that categorized odontocete pulsed sounds had few means of discriminating signals used for biosonar-based foraging from those used for communication. This capability to identify the function of sounds is ...
  • Sperm whale predator-prey interactions involve chasing and buzzing, but no acoustic stunning 

    Fais, A.; Johnson, Mark; Wilson, M.; Aguilar de Soto, Natacha; Madsen, P. T. (2016-06-24) - Journal article
    The sperm whale carries a hypertrophied nose that generates powerful clicks for long-range echolocation. However, it remains a conundrum how this bizarrely shaped apex predator catches its prey. Several hypotheses have ...
  • Disturbance-specific social responses in long-finned pilot whales, Globicephala melas 

    Visser, Fleur; Curé, Charlotte; Kvadsheim, Petter H.; Lam, Frans-Peter A.; Tyack, Peter L.; Miller, Patrick J O (2016-06-29) - Journal article
    Social interactions among animals can influence their response to disturbance. We investigated responses of long-finned pilot whales to killer whale sound playbacks and two anthropogenic sources of disturbance: Tagging ...
  • Vocal Learning and Auditory-Vocal Feedback 

    Tyack, Peter Lloyd (Springer, 2016) - Book item
    Vocal learning is usually studied in songbirds and humans, species that can form auditory templates by listening to acoustic models and then learn to vocalize to match the template. Most other species are thought to develop ...
  • Novel application of a quantitative spatial comparison tool to species distribution data 

    Jones, Esther Lane; Rendell, Luke Edward; Pirotta, Enrico; Long, Jed A. (2016-06-15) - Journal article
    Comparing geographically referenced maps has become an important aspect of spatial ecology (e.g. assessing change in distribution over time). Whilst humans are adept at recognising and extracting structure from maps (i.e. ...
