Dr. Silvina Botta from ECOMEGA FURG, our partners in Brazil, is currently visiting the Endocrinology Laboratory at Toronto Zoo for a YAQU PACHA-sponsored training program on hormone analysis in marine mammals. Stress-associated hormones such as cortisol are being analyzed in samples from bottlenose dolphins collected by ECOMEGA FURG and PROJETO BOTOS. The samples were obtained from tooth dentin using the automated MicroMill drilling system at ECOMEGA FURG. The main objective is to link stress hormone levels to environmental factors such as changes in prey availability or deteriorating habitat conditions.
