My contribution to dolphin conservation comes not from observing bottlenose dolphins directly in the warm Sarasota sun but rather by exploiting new mass spectrometric techniques that allow me to uncover various attributes of foraging habits by measuring tiny amounts of animal tissue. These techniques involve analysis of the stable isotopes of carbon. Different types of [...]

This will be the first time that stable isotope analysis will be applied to individual annuli of bottlenose dolphin teeth.
