Congratulations to Emma Chereskin for winning the University of Bristol Faculty of Life Sciences Award for best Masters by Research (MScR) thesis! This work was published earlier this year in Current Biology
(you can find the article here) and we can't wait to see what comes out of Emma's PhD research (we are lucky that Emma will be staying with CetaceanCommCog for her PhD, funded by the University of Bristol International PhD Scholarship).
HUGE Congratulations to Katy Holmes for passing her viva! Katy's thesis investigated the ontogeny of male alliance behaviour in juvenile bottlenose dolphins (Tursiops aduncus) in Shark Bay and we look forward to sharing publications from Katy's exciting doctoral research in the near future. Big thank you to Shane Gero and Jennifer Smith for examining the thesis!

We are pleased to share our recent paper in PNAS on strategic intergroup alliances in male bottlenose dolphins:
RC Connor, M Krützen, SJ Allen, WB Sherwin and SL King (2022). Strategic intergroup alliances increase access to a contested resource in male bottlenose dolphins. Proceedings of National Academy of Sciences 119 (36), e2121723119.
This research shows that male bottlenose dolphins form the largest known multi-level alliance network outside humans, and that dolphins benefit from intergroup cooperation. This is striking because intergroup cooperation was thought to be unique to humans and dependent upon two other features that distinguish us from our common ancestor with chimpanzees: the evolution of pair bonds and parental care by males. However, our work shows that intergroup cooperation can emerge without these features in a chimpanzee-like, promiscuous mating system.
The paper is free to access and can be found here.
