spitz-tThe Science of Stress: A Nutrigenomic Approach

What if scientists could take a single drop of blood to determine whether sea lions are nutritionally stressed? In a new study, Consortium researchers have shown that it is indeed possible to detect changes in nutritional status from simple changes in gene expression contained within blood samples. This new technology can help identify sea lions that are in distress, and may provide a means to determine whether fishery management actions are effective at reversing nutritional stress.

The Consortium is conducting a long-term research program on Steller sea lions, northern fur seals and other marine mammals and their interactions with fisheries, other species and oceanographic conditions in the North Pacific Ocean and Eastern Bering Sea.
