Comparison of progesterone concentrations in blubber and plasma among female Antarctic minke whales of known reproductive status
Abstract The utility of progesterone concentration in blubber as a means of determining reproductive status in the Antarctic minke whale Balaenoptera bonaerensis was assessed through a comparative analysis of progesterone concentration in blubber and plasma among 230 female whales of known reproduct...
