New paper on Hawaiian Spinner Dolphin Abundance

I’m happy to announce the publication of the first quantitative abundance estimate for spinner dolphins on the Kona Coast of Hawaii Island. This work, led by Julian Tyne and part of the joint Duke/Murdoch SAPPHIRE project provides managers much needed information for managing human effects on this species in Hawaii.

This newly identified stock of spinner dolphins is small – apron 631 individuals (±60.1 SE, 95% CI 524–761).

Congratulations to Julian and the rest of the SAPPHIRE team.
