2. On the estimation of some demographic parameters for Adelie penguins

   Abstract:  A population dynamics model for Adelie penguins is developed which takes account of the ... factors of lower adult survival rates in the year of first breeding, and the possibility that such ... breeding may be deferred one year if conditions are poor. A Bayesian approach for estimation of the model ... for illustrative purposes. The results for this case would likely be improved by the provision of more ...
