Growth and bioenergetic models for stellar sea lions (eumetopias jubatus) in Alaska ...
The primary goal of my study was to develop a bioenergetic model to predict the food requirements of Steller sea lions (Eumetopias jubatus). An important component of the bioenergetic model was a physical growth model. Growth models were constructed using morphometric measurements of males (> 1 y...
