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 ... tested by simulation, and it is applied to preliminary data for penguin colonies in the South Shetlands ...

Comparison of age- and length-based harvest control rules for the South Georgia icefish (Champsocephalus gunnari) fishery
age vector for the population. An age-based harvest control rule was then applied using the operating ... model dynamics and assuming perfect knowledge of the resource (initial numbers at age, maturity and ... weight at age). The initial numbers at age was also converted to numbers at length, which was used to ... initialise the length based harvest control rule, again assuming perfect knowledge of the resource. Total ...
